Repair positive film. In the case of major corrections, a proof print is made using the corrected decomposition film and submitted to the customer again for review. In case of partial correction (
In other words, if the film is valuable, the corrected positive film is blueprinted (on diazo paper) and checked by a third party internally. In this case, the complicated thing is that when there is a combination of multiple colors in the corrected area, you have to compare the blueprints of each color, and for example, for the purple part, you have to inspect the blueprint of the eye version and the blueprint of the red version. Must be. Also, when correcting a certain part in green, that pattern exists only in the eye version and the key version,
You must confirm that the pattern does not exist in the red version and the θ-sumi version.

る。Here, the photosensitive belt is an endless belt, and is made of a flexible thin plate of non-magnetic metal such as nickel or stainless steel, and is coated with ZnO-resin, 'Cd5-resin, Se, black liquor, etc. A material provided with a photoconductive layer such as an organic photo-semiconductor can be used. Further, the length of the photosensitive belt is equal to the circumferential length of the moving locus of the transparent circular arc member, and the circumferential length of the transparent circular arc member is at least shorter than the distance between the transfer position and the cleaning position of the photosensitive belt. After the transfer, the photosensitive belt can be stopped at the point where the pin bar attached to the photosensitive belt is in front of the static elimination lamp,
It is kept ready to respond quickly to the next iteration.

簡単に、精度良くスリット露光できるものである。In addition, the transparent arc member is made of transparent resin or glass, but unlike a cylindrical transparent drum, it can be manufactured by bending a flat plate rather than by molding, so it can be manufactured at low cost and with high precision. The reason why the shape of the transparent arc member is an arc is, in addition to the above-mentioned manufacturing reasons, to prevent the transparent arc member from being damaged by pressing on the bin bar attached to the photosensitive belt. Therefore, the transparent circular arc member and the photosensitive belt are moved in synchronization, and the decomposed mesh positive film is moved onto the photosensitive belt while avoiding the bin bar attached to the photosensitive belt, and the film is brought into close contact with the elastic pressure roll to easily and accurately slit the film. It can be exposed to light.

を転写シートに転写する。Next, a series of operations of the color copying machine of the present invention will be described in detail. First, the separation net positive film, which has been registered in advance and has a hole punched in the document tray, is placed in the order of the following: Stack them from the bottom and put them in place. Next, the photosensitive belt is charged while moving, and the decomposed mesh positive film of the sumi plate is adsorbed from the document tray by a sucker, moved onto the photosensitive belt, and attached to the photosensitive belt while synchronizing with the moving speed of the photosensitive belt. The transparent circular arc member is inserted and fixed into a bin bar that is attached, and is moved so as to overlap the charged photosensitive belt, and the transparent arc member is rotated and moved in synchronization with the photosensitive belt, so that the bin bar does not come into contact with the transparent arc member. Passing directly above the pressure roll 1-
Immediately after, while the decomposition net positive film is passing over a pressure roll, the decomposition net positive film is brought into pressure contact with the photoreceptor belt, and while the decomposition net positive film is in pressure contact with the photoreceptor belt, exposure is performed. Close-contact slit exposure is performed using a lamp, and then the separation net positive film is moved and adsorbed by a sucker to separate it from the photoreceptor belt.The photoreceptor belt with the electrostatic latent image formed thereon is moved to a developing unit, where a dark-colored developer is applied. A developing device housing the photosensitive belt is moved close to the photosensitive belt and developed.The transfer sheet is sent out and attached to the transfer drum, and the developed photosensitive belt is moved and comes into contact with the transfer sheet on the transfer drum. The developed image is transferred to the transfer sheet.Next, the photoreceptor belt after transfer is destaticized, cleaned, and charged again, and the eye plate decomposition mesh positive film is transferred from the original tray to the suction cup 7 (thus, it is attracted to the photoreceptor belt). The eye image is transferred to the transfer sheet using the same procedure.

Next, the transfer sheet on which the four-color toner images of black, eye, red, and yellow have been transferred is separated from the transfer drum and fixed by a fixing device to obtain a four-color color reproduction.
以上のような操作で得られた複製物を検版の用途に使い

よる各色の露光量を変化させる方法が用いられてきた。In conventional color copying machines, color-separated images of a reflective original are sequentially projected onto a photoreceptor, but the spectral energy distribution of the light source, the spectral sensitivity distribution of the photoreceptor, and the spectral energy distribution of the color separation filter are different for each color. Since each separated image is significantly different, methods have been used to adjust the differences in the overall sensitivity of blue, green, and red by changing the exposure time of each color or the exposure amount of each color by adjusting the ND filter or lens aperture. .

。On the other hand, in the color copying machine of the present invention, since separation net positive film is used for the original, color separation filters are not necessary. There is no need to change the exposure amount. In addition, the exposure method of the present invention is not a method of exposing through a lens, but a contact exposure method using a transparent original, so the reproduction is faithful to the original,
Accuracy is also good. Further, the color of the toner of the developer used in the present invention must be close to that of the ink actually used in offset printing. And in the case of full color, as with general offset printing, there are
It is a combination of four colors, black and white, and not a combination of three colors, cyan, magenta, and yellow, as in conventional color copying machines.

複製物は良質なものとなる。The color copying machine of the present invention uses separation net positive film of each color, which has already been registered and has bin holes, as an original.
By fixing the original to the bin bar of the photosensitive belt, the registration between the four-color images of yellow, red, eye, and black is accurate.In addition, since the contact exposure method is used, the resulting color reproduction is will be of good quality.

製物が得られる。In addition, the decomposition net positive film can be automatically attached and detached from the photosensitive belt.
Since the photosensitive belt roller does not stand still and moves continuously to repeat charging, exposure, development, and transfer, color reproductions can be obtained in a short time. In addition, because the developing units are separated for each color and are moved close to the photosensitive belt to perform development in response to the separation mesh positive film, there is a risk that toner of a different color may mix in each developing unit. You can obtain clear color reproductions with fewer copies.
