Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a silver halide color photographic light-sensitive material. The present invention relates to a method for processing a light-sensitive material having emulsions having different silver halide compositions and different development behavior. Another object of the present invention is to provide a processing method capable of maintaining excellent photographic characteristics, and capable of simultaneously processing photosensitive materials having emulsions having different silver halide compositions by simple modification.

[0002]

2. Description of the Related Art Among silver halide color photographic light-sensitive materials, photographic film light-sensitive materials (hereinafter also referred to as films) used for photography have a larger amount of silver applied than print materials (hereinafter also referred to as prints). Generally, the load on the development step and the desilvering step is large, and therefore, the development processing time is generally long. On the other hand, recent color labs (developers)
Due to the decentralization of small labs, the number of small color labs called minilabs that perform development processing (hereinafter simply referred to as “processing”) at stores such as photo shops in the market is increasing. The tendency to replace the collection and delivery processing on the premise of collection and delivery is remarkable. In the in-store processing, it is particularly important to shorten the finish delivery time, and it is particularly desired to reduce the processing time of a long film.

[0003] As a means for shortening the film processing step, instead of a conventionally used film containing a high silver bromide emulsion in which the main component of silver halide is silver bromide, silver halide is mainly used. Films containing high silver chloride emulsions whose component is silver chloride are disclosed. Compared to the former, the latter has a higher reaction rate during development and has almost no iodine ion release which hinders the fixing process, and thus can be said to be an emulsion excellent in rapid processing and reduction in replenishment amount. An example of such a high silver chloride emulsion is disclosed in
No. 2,299,932 discloses a technique containing a high silver chloride emulsion having a (111) plane. Also, US Pat.
No. 64337 discloses a tabular emulsion having a (100) plane.

Although such high silver chloride type photographing materials have the advantage of being excellent in rapid developability, the current color photographic and color lab markets are composed of high silver bromide type photographing materials. There is no system for developing high silver chloride type photographic materials. High silver chloride type photography material was introduced and spread, it became the main photography material in the market,
If a dedicated development service network is completed, users will be able to obtain many benefits, but at the beginning of the introduction of high silver chloride photographic materials, it is not enough to have a new processing development service network for introduced photographic materials. Instead, a development service may be performed using an existing processing system for a film using a high silver bromide emulsion. That is, at the beginning of the introduction of the high silver chloride photographic material, it is expected that a mixing process of the old and new photosensitive materials will be performed. Both photographic materials having silver halide emulsions and photographic materials having high silver chloride emulsions have remarkable fluctuations in photographic characteristics (especially sensitivity and gradation), making it difficult to maintain photographic performance. found. Needless to say, if the market is all changed to a photographic material having a high silver chloride emulsion, a dedicated developing process can be performed, and such a problem can be solved. In the stage of introduction of high silver chloride photography materials, if the same processing as conventional high bromide photography materials must be performed, if the replenisher for conventional high bromide photography materials can be used in common, a new type of photography As the difficulties hindering the introduction of materials are solved, a proposal for a new replenishment method that makes this possible is awaited.

[0005]

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific embodiments of the method for processing a silver halide color light-sensitive material of the present invention will be described in detail. The silver halide color photographic light-sensitive material for photography currently distributed in the color photographic market has a silver bromide content of 50 to 50%.
A material containing 100 mol% of a high silver bromide emulsion (hereinafter also referred to as a photographic material A or a film A). In the global color photographic market, photosensitive material manufacturers supply corresponding photosensitive materials containing high bromide emulsions, and each color lab performs the same development process regardless of the manufacturer. In the present invention, all of these are referred to as photographing material A or film A.

A silver halide color photographic light-sensitive material for photography, which is desired to be introduced because of its advantages such as rapid developability, is a high silver chloride emulsion having a silver chloride content of 50 to 100 mol%. (Hereinafter also referred to as photographing material B or film B). As with the film A, this type of film is referred to as a film B regardless of the supplier of the photosensitive material.

As a method of processing the film A and the film B with a common color developer, Japanese Patent Application Laid-Open No. 9-204 discloses
No. 030 discloses that two types of replenishers having different bromine ion concentrations are prepared and processed based on the silver bromide content and the processing amount of the two. On the other hand, in the present invention, not only the replenishing amount of the color developing replenisher but also the concentration of the replenishing solution is changed in accordance with the processing amounts of the two, so that it is more stable and the adjustment for each small fluctuation of the processing amount becomes unnecessary. This is a method that enables simple development processing. In addition, by changing both the replenishing amount and the concentration, it is not necessary to set the replenishing amount to be high, and practical replenishment can be performed economically and with a small amount of waste liquid.

Here, the concentration of the replenisher refers to the concentration of the constituent to water in which the constituent is dissolved in the formulation of the replenisher. In other words, it refers to the concentration obtained by changing the amount of water in the replenisher while keeping the relative amount ratio relationship between the individual constituents of the replenisher constant.

In the present invention, film A and film B
The replenishment amount and the concentration of the color developing replenisher in the common processing are changed so as to keep the bromine ion concentration in the developing tank within an allowable range centered on the standard concentration. The term "standard density" as used herein refers to a density determined to make the photographic characteristics of the film a standard finish. The standard concentration is
It is determined at the stage of development processing design, and the development operation is performed to maintain this standard density. Further, the allowable range of the density fluctuation around the standard density of the density in the developing tank is determined so that the fluctuation of the photographic characteristics is within an allowable range. The range in which the change in the photographic characteristics is acceptable is within a range in which a finish satisfying most users can be obtained, and is specifically described in International Standard ISO10977 and the like. In the present invention, the replenishing amount and the concentration of the replenisher are set so that the fluctuation of the bromine ion concentration is kept within this range.

The specific contents of changing both the replenishing amount and the concentration of the color developing replenisher will be described.
When the film B is mixed and processed simultaneously in the developing device that is processing the film A, the amount of bromide ions released into the developing solution during the development of the film B is small, so that the bromine ion concentration in the developing tank is reduced as it is. As a result, the photographic properties of the finished film become unsatisfactory. Therefore, it is generally necessary to change the composition of the replenisher. However, in the method of the present invention, the amount of replenishment added to the developing tank is reduced to maintain the bromine ion concentration in the developing tank (the replenisher does not contain bromine ions, or even if it does contain bromine ions, Lower than the concentration). When the replenishing amount is reduced, even if the bromine ion concentration can be maintained, the concentration of other constituent chemicals such as the color developing agent cannot be maintained. Therefore, in the present invention, the concentration of the replenisher is also changed so that the concentrations of other constituent chemicals in the developing tank can be maintained. This is the essential point of the present invention in which two types of films can be developed simultaneously by changing both the replenishing amount and the density. According to this method, even if the mixing ratio of the film B changes, there is no need to change the prescription of the basic replenisher, and the replenishment amount and concentration of the replenisher during use (that is, the water for dilution or dissolution used in the preparation) It is possible to respond only by changing the amount.

In particular, it is further preferable that the replenishment amount and the concentration are changed so that not only the bromine ion but also the color developing agent is kept within an allowable range centered on the standard concentration. As a guideline for the development of ordinary color light-sensitive materials for photography, the bromine ion concentration in the developing tank differs slightly from the prescription set concentration depending on the product of each brand,
Up to ± 10% (usually about ± 0.14 g / liter)
Photographic properties are almost acceptable. Further, the concentration of the color developing agent can be almost tolerated up to ± 10% (usually about ± 0.5 g / liter) with respect to the set concentration. Also, the pH of the developer
A variation range of ± 0.01 is acceptable. Therefore, according to the present invention, both the concentration and the replenishment amount of the developing replenisher are changed in accordance with the change in the mixing ratio of both photosensitive materials, and these concentration values and pH values in the developing tank, in particular, the bromine ion concentration value Is maintained within an allowable range in which the photographic characteristics of both photosensitive materials are maintained.

The above is the basic method of the present invention, and specific embodiments when applied to each of the main color developing methods will be described below. In the following description of the embodiment of the present invention, "change both the replenishing amount and the concentration of the replenishing solution" means:
If the replenisher is a liquid, change the volume and concentration. If the replenisher is a solid (powder, granule, tablet, etc.), adjust the amount and concentration of the corresponding replenisher. The corresponding change in solids weight and water (dilution water) per charge. In the latter case, it is possible to substantially "change both the replenishing amount and the concentration of the replenishing solution" by changing the interval and speed of charging the solid and water (diluting water) as described later. In many color labs, especially mini labs, replenisher solutions are prepared by dissolving or diluting a preparation agent supplied by a processing agent manufacturer in water at a specified ratio. When the present invention is applied to a developing process using a compounding agent, the concentration of the color developing replenisher can be changed by using the developing replenisher of the compounding agent supplied on the market as it is and preparing the replenisher. By changing the amount of water for dissolution or dilution.

The processing agent (including solid processing agents in addition to those in the form of an aqueous solution) of a development replenisher may be a single composition or may be a plurality of compositions (usually individual compositions). The composition may be referred to as a part). In any case, when these are dissolved or diluted in water to prepare a replenisher, in the present invention, the concentration of the replenisher is changed by changing only the amount of water that dissolves or dilutes the preparation agent. So simple and practical.

Instead of preparing a replenisher by mixing each part (including a single component part) with water for dissolution and dilution, and then putting the mixture into the developing tank, There is also a method disclosed in, for example, Japanese Patent Application Laid-Open No. 7-295190 in which water is separately charged into a developing tank and substantially dissolved and diluted in the developing tank. When the development processing method of the present invention is applied to this method, the concentration of the development replenisher is changed by changing the amount of water supplied relative to the amount of each part, and the intervals between the parts of the processing agent are changed. It is a practically preferable embodiment to change the replenishment amount of the replenishment medicine by changing. When a high silver chloride photosensitive material is mixed with a high silver bromide photosensitive material, the concentration of the replenisher added is increased by slowing down the injection speed of water with respect to the injection speed of each part, and at the same time, Replenishment speed also slows.

As the compounding agent, a solid compounding agent having a part composition (including a single component part) and water for dilution are charged into a developing tank, for example, as disclosed in JP-A-5-107712. There is also a method. When the development processing method of the present invention is applied to this system, the concentration of the development replenisher is substantially changed by changing the ratio of the water supply interval or the supply speed to the supply interval of each part,
It is a practically preferable embodiment to substantially change the replenishment amount of the replenishment chemical by changing the feeding interval of each solid processing agent part.

In a general-purpose color developing method, a concentrated processing replenisher is prepared by dissolving a compounding agent with water, and the concentrated replenisher and water for dilution are added to a developing tank. For example, Japanese Patent Application Laid-Open Nos. 8-248606 and 8-2
There is also a method disclosed in Japanese Patent No. 34389. In this case, the replenishing amount is changed by changing the feeding speed or the feeding interval of the concentrated replenisher, and the bromine ion concentration and the like are changed by changing the feeding interval (or speed) of the water for dilution. Maintain each component concentration.

In the present invention, the film A is a film containing a silver iodobromide emulsion containing 0.1 to 15 mol% of iodine ions, and is regarded as representative of a conventional general-purpose film. On the other hand, the film B is (100)
A film containing a high silver chloride emulsion consisting of tabular silver halide grains having a silver chloride content of 50 to 100 mol% and having a major surface as a main plane, and a film expected to be a general-purpose film in the future. I assume.

As can be seen from the above description, it is desirable that the developing replenisher used in the developing method of the present invention is a developing replenisher supplied to the market for the film A or presented as a prescription. In the case of this development replenisher, the supply of processing chemicals and processing agents is ensured, and the development processing method is established for the film A. Thus, it can be modified according to the method of the present invention described above. Therefore, in the mixing process, there is no need to change the preparation agent for development or the formulation of the developing replenisher, and the remodeling of the developing apparatus is unnecessary or can be kept to a very small extent.

A part of the above is repeated.
Is the development process in the current market where film A is mainly used?
Film B is introduced and mixed, and eventually
Of the present invention before film B became the main market
An embodiment of the image processing method will be specifically described. the film
In the current color lab where A is the main body, there is a dedicated film A
Processing is taking place. In this process, the development replenishment amount is
200-1500 mm
Liter / m^TwoAnd the bromine ion concentration in the developing tank is 8
× 10 ^-3~ 13 × 10^-3Mol / l
Preferably, more preferably 1 × 10^-2~ 1.2 × 10^-2
It is in the mole / liter range.

As a general-purpose form of the developing replenisher, A agent,
It is composed of parts consisting of three agents called agent B and agent C, and when water is added to make up a replenisher, agent D,
When a replenisher is made by adding water to a two-part component called E-agent, it may be made up of a one-part component called F-agent and made into a replenisher by adding water. . Further, these parts and water may be respectively fed by a metering pump to be automatically prepared. Further, as described above, each of them may be automatically sent to the developing tank, and substantial preparation and replenishment may be performed in the developing tank. Further, even if a part or the whole of the parts is a solid processing agent, it is substantially the same, except that the liquid is supplied instead of the solid material.

Here, the method of the present invention is started when the film B is introduced into the market and mixed. The replenishing amount is changed according to the mixing ratio of the film B. For example, when the film B is a film containing no silver bromide and the ratio is 20%, the bromine released into the developing tank during the development is reduced. Since the amount of ions is reduced by 20%, if the replenishing amount is reduced by 20% correspondingly, a constant bromine ion concentration is maintained by the bromine ions released from the film A to the developing tank during the development and the replenisher. Even when the film B is introduced, it is necessary to maintain the bromine ion concentration in order to maintain the finished quality of the film. On the other hand, if the replenishment amount is reduced, the concentration of the constituent chemicals consumed in the developing solution such as the color developing agent cannot be maintained as it is, so that the concentration of the consumed constituent chemicals is reduced by the amount corresponding to the reduction in the replenishment amount. By increasing the concentration by 20%, the concentration can be maintained, and it can be dealt with by reducing the amount of water when preparing the replenisher by 20%.

More generally, the emulsions of Film A and Film B have silver bromide contents of a mol% and b mol%, respectively.
Mol% and the mixing ratio of the film B is x%, the replenishment amount V1 in the mixing process is represented by the following formulas. V1 = V × [a × (1-0.01x) + b × 0.01
x] / a Further, the concentration rate of the replenisher is approximately V / V1. Here, V is the replenishment amount when only the film A is developed. The replenishment amount and the concentration of the replenisher can be changed continuously according to the change in the mixing ratio x, but more practically, may be changed stepwise as x increases. For example,
The following configurations are possible. Film A in the color lab
Photosensitive material called film B is requested by various photosensitive material manufacturers for development under various brand names with different sensitivities and the like. A wide processing formula is designed. Therefore, even if the following gradual changes are made, a substantial decrease in photographic characteristics is usually avoided.

X is between 0 and 10%: V1 = 95%. x is between 11 and 20%: V1 = 85%. x is between 21 and 30%: V1 = 75%.

In this method, the replenishing amount was reduced from 100% to 95%, 85%, and further to 75% with the increase of the mixing ratio of the film B, and a replenisher having a correspondingly higher concentration was used. Process. By this method, up to a mixing ratio of the film B of 50%, development processing can be performed while maintaining the photographic characteristics of the finished film within an allowable range. When the mixing ratio of the film B is further increased, the replenishing amount may be further reduced accordingly.
It is more preferable to use the method of separately adding bromine ions proposed in JP-A-2004030.

The mixing ratio of the film A and the film B can be known by the number of orders for development requests from the user, but a simpler method is to use a DX code reading device in the development processing device. By attaching it, each film type of the film A and the film B can be counted, and it can be known from the integrated value. Further, in a large-scale developing laboratory which performs analysis and management of the developing solution, when the composition of the tank solution in the developing tank is monitored and the ratio is out of an allowable range centered on the standard value, the film B is removed. It is also possible to adopt a method of changing the setting of the replenishing amount and the replenishing solution concentration at a stage where the mixing ratio is high.

As the common color developing replenisher used in the above-mentioned developing method, chemicals and compounding agents currently supplied by the respective processing chemical manufacturers and processing agent manufacturers can be continuously used.

The development replenisher or replenisher contains an aromatic primary amine color developing agent as an essential component. Aminophenol compounds are also useful as the color developing agent, but p-phenylenediamine compounds are preferably used.

In the processing method of the present invention, after color development, desilvering is performed. In the desilvering step, it is desirable that both photosensitive materials be processed with a common tank solution and a common replenisher. However, the replenishment amount can be set differently for each photosensitive material, and the replenishment amount may be appropriately changed according to the mixing ratio.

Can be used as is.

In the desilvering step, it is preferable that the stirring is strengthened as much as possible. As a specific method of strengthening stirring, a method described in JP-A-62-183460, in which a jet of a processing solution is made to impinge on the emulsion surface of a photographic material, and a method described in JP-A-62-1834.

And a method of increasing the circulation flow rate of the entire processing liquid. Such a stirring improving means is effective for any of a bleaching solution, a bleach-fixing solution and a fixing solution. It is considered that improving the stirring speeds up the supply of the bleaching agent and the fixing agent into the emulsion film, and consequently increases the desilvering speed. Further, the above-described means for improving the stirring is more effective when a bleaching accelerator is used, and can significantly increase the accelerating effect or eliminate the fixing inhibiting effect of the bleaching accelerator.

The automatic developing machine used for the light-sensitive material of the present invention is described in JP-A-60-191257, JP-A-60-191258 and JP-A-60-1912.

As described in the above-mentioned JP-A-60-191257, such a conveying means can significantly reduce the carry-in of the processing solution from the pre-bath to the post-bath, and is highly effective in preventing the performance of the processing solution from deteriorating. Such an effect is particularly effective for reducing the processing time in each step and reducing the replenishing amount of the processing solution.

The overflow solution accompanying the washing and / or replenishment of the stabilizing solution can be reused in other steps such as a desilvering step. In processing using an automatic developing machine or the like, when each of the above processing solutions is concentrated by evaporation,
In order to correct the concentration by evaporation, it is preferable to replenish an appropriate amount of water or a correction solution or a processing replenisher. There is no particular limitation on a specific method for performing water replenishment. Among them, a monitor water tank separate from the bleaching tank described in JP-A Nos. 1-254959 and 1-254960 is installed, and water in the monitor water tank is provided. The amount of evaporation of water in the bleaching tank is calculated from the amount of evaporation of water, and the amount of water in the bleaching tank is replenished in proportion to the amount of evaporation.
The evaporation correction method using a liquid level sensor or an overflow sensor described in JP-A Nos. 3-249644, 3-249645 and 3-249646 is preferable.
Tap water may be used as the water for correcting the evaporation of each processing solution, but it is preferable to use deionized water or sterilized water which is preferably used in the above-mentioned washing step.

[0055] For drying method is any method can be selected, it is preferable to use a ceramic hot air heater is preferably min 4m ³ to 20 m ³ as feed air volume, particularly 6 m ³ through 10m ³ preferred.

Next, the photographic material used in the present invention will be described in detail. The preferred silver halide composition of the high silver bromide photosensitive material used in the present invention is a silver iodobromide or silver iodochlorobromide emulsion containing about 40 mol% or less of silver iodide. Particularly preferred is from about 0.1 mol% to about 15 mol%
Silver iodobromide containing up to silver iodide. The preferred silver halide composition of the high silver chloride photographic material used in the present invention is a silver chlorobromide emulsion containing about 50 mol% or less of silver bromide or a pure silver chloride emulsion. Preferred is silver chloride or silver chlorobromide which is substantially free of silver bromide, or at most about 10 mole%, and more preferably 5 mole% or less. Further, if necessary, a small amount (10 mol% or less) of silver iodide may be contained.

Next, both silver halide emulsions used in the present invention, which have been referred to as film A and film B, may be emulsions of any shape such as octahedral, cubic, spherical, etc., and preferably tabular emulsions. It is preferred to contain at least one layer. Particularly, in the latter high silver chloride emulsion, a tabular silver halide emulsion having a (100) plane is preferable. Hereinafter, tabular silver halide emulsions that are preferably used will be described in detail. In the tabular silver halide emulsion used in the present invention, the average aspect ratio means the average value of the ratio of the diameter to the thickness of silver halide grains. That is, it is the average of the values obtained by dividing the diameter of each silver halide grain by the thickness. Here, the diameter refers to the diameter of a circle having an area equal to the projected area of the grain when the silver halide emulsion is observed with a microscope or an electron microscope. Therefore, an average aspect ratio of 2: 1 or more means that the diameter of the circle is twice or more the thickness of the particle.

In the tabular silver halide grains used in the silver halide emulsion to which the present invention is applied, the grain size is at least twice the grain thickness, preferably 3 to 20 times, more preferably 4 to 20 times. It is 15 times, particularly preferably 5 to 10 times. The proportion of tabular silver halide grains in the projected area of all silver halide grains is at least 50%, preferably at least 70%, particularly preferably at least 85%.

By using such an emulsion, a silver halide photographic material having excellent sharpness can be obtained. The sharpness is excellent because the light scattering by the emulsion layer using such an emulsion is extremely small as compared with the conventional emulsion layer. This can be easily confirmed by those skilled in the art using experimental methods that can be used on a daily basis. The reason why the light scattering of the emulsion layer using the tabular silver halide emulsion is small is not clear, but it is considered that the main surface of the tabular silver halide emulsion is oriented parallel to the support surface.

Further, the diameter of the tabular silver halide grains is in the range of 0.1 to 0.3.
It is 2 to 20 μm, preferably 0.3 to 10.0 μm, and particularly preferably 0.4 to 5.0 μm. The thickness of the particles is preferably 0.5 μm or less. Here, the tabular silver halide grain diameter refers to the diameter of a circle having an area equal to the projected area of the grains. The thickness of the grains is represented by the distance between two parallel planes constituting the tabular silver halide grains.

More preferred tabular silver halide grains used in the present invention have a grain diameter of 0.3 μm to 10.0 μm.
m or less, the particle thickness is 0.1 μm or more and 1.0 μm or less, and the average aspect ratio (diameter / thickness) is 3 or more and 1 or more.
0 or less. If the aspect ratio exceeds 10, the photographic performance may be abnormal when the photosensitive material is bent, wrapped tightly, or touched by a sharp object, which is not preferable. More preferably, the particle diameter is 0.4 μm or more.
This is the case of a silver halide photographic emulsion in which grains having a mean aspect ratio (diameter / thickness) of 5 μm or less and 0 or less account for 85% or more of the total projected area of all silver halide grains.

The tabular silver halide grains of the light-sensitive material to which the present invention is applied are preferably the silver bromide, silver iodobromide, silver chloride and silver chlorobromide described above. The composition distribution may be uniform or localized.

The grain size distribution of the tabular silver halide grains of the light-sensitive material to which the present invention is applied may be narrow or wide. The amount of silver applied is about 2 to 10 g per square meter of the light-sensitive material, and particularly preferably 2 to 6 g, and most preferably 2.5 to 5.5 g for a high silver chloride photographic material. The silver halide emulsion composed of tabular silver halide grains of the photosensitive material to which the present invention is applied is Cugn.

For example, a relatively high pA having a pBr of 1.3 or less
tabular silver halide grains in an atmosphere having a g value of 40
% Of a seed crystal is formed, and the seed crystal is grown while simultaneously adding silver and a halogen solution while maintaining the same pBr value. It is desirable to add a silver and halogen solution so that no new crystal nuclei are generated during the grain growth process. The size of the tabular silver halide grains can be adjusted, for example, by controlling the temperature, selecting the type and quality of the solvent, and controlling the addition rate of the silver salt and halide used during grain growth. In the production of the tabular silver halide grains of the present invention, a silver halide solvent may be used as necessary to obtain a grain size, a grain shape (for example, diameter / thickness ratio), a grain size distribution, and a grain growth rate. Can be controlled. The amount of the solvent used is preferably in the range of 10 ^{-3 to} 1.0% by weight of the reaction solution, and particularly preferably in the range of 10 ^-2 to 10 ^-1 % by weight. In the present invention, the particle size distribution can be monodispersed and the growth rate can be increased with an increase in the amount of the solvent used, but the thickness of the particles tends to increase with the amount of the solvent used.

In preparing the silver halide grains of the photographic emulsion used in the present invention, known silver halide solvents can be used. Examples of frequently used silver halide solvents include ammonia, thioether,

That is, silver halide grains taken out of the emulsion with care not to apply enough pressure to generate dislocations on the grains are placed on a mesh for observation with an electron microscope to prevent damage (for example, printout) by electron beams. Observation is performed by a transmission method in a state where the sample is cooled as described above. At this time, the thicker the particles, the more difficult it is for an electron beam to pass. Therefore, a high-pressure type (200 k
The use of the electron microscope of V) allows clearer observation. From the photograph of the particles obtained by such a method, it is possible to observe the position and number of dislocations for each particle when viewed from the direction perpendicular to the main plane.
