Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a thermal transfer printing method and a thermal transfer printer suitable for producing ID cards, cash cards, etc., and particularly relates to a technology for preventing children from producing these printed products. .

(Prior art) Conventional identification cards, ID cards such as driver's licenses, and some cash guards have information such as date of issue, registration number or certificate number,
It is created by pasting a photograph of a person's face on a card on which the name of the certification body, the name of its representative, and the name of the person in question are printed, and affixing the seal of the certification body or its representative. Of these, color photographs are common these days.

It is known that a color image such as a color photograph can be input using a scanner and reproduced by a color printer using an inkjet printer, an electrophotographic printer, a thermal transfer method, or the like.

In addition, in order to print such color images together with characters and symbols such as the date of publication and the person's name, for example, in a thermal transfer color printer, color materials containing cyan, magenta, yellow, and black if desired are used. A transfer film formed by dividing each transfer layer is conveyed sequentially to cover the recording paper with each transfer layer of the transfer film, and a thermal line head in which a headline in which printed dots are arranged in a line is arranged and fixed is used. Color printing has been proposed (Japanese Patent Laid-Open No. 11370/1983).

Furthermore, in order to protect the images obtained in this way,
It has been proposed to use a transparent transfer film with a transparent transfer layer formed on the entire back surface, and to transfer the transparent transfer layer of the transparent transfer film onto the obtained image (1986-
No. 5856, JP-A No. 60-23096).

If an ID card or cash card is created using this type of color printing technology, a face photo is pasted on the card with the date of issue, registration number or certification number, name of the certification authority, name of its representative, and the name of the person printed in advance. Compared to the case where the person's name and face photo read by a scanner are stored in memory in advance, these can be read out from memory, input, and printed, so the person's name and face photo can be stored in memory. In addition to being able to create ID cards and cash cards without fail, there is no need to attach a face photo, so the advantage is that the ID card, cash card, etc. created by peeling off the face photo cannot be discarded. be.

In addition, after creating an ID card, cash card, etc., please be sure to enter information such as the date of issue, registration number or certificate number, face photo, and name of the person, which varies from person to person, in case a problem arises later. Another advantage is that it can be stored and stored in memory in correspondence.

In addition, the thermal transfer method has the advantage that clear color images with excellent storage stability can be printed by selecting the coloring material in the transfer layer in the ink ribbon.

Furthermore, if a transparent transfer film with a transparent transfer layer formed on the entire back surface is used and the transparent transfer layer of the transparent transfer film is transferred onto the resulting image, the issue date may vary depending on the individual depending on the transparent transfer layer. , registration number or certificate number, and the person's name can be prevented from being stolen.

(Problem to be Solved by the Invention) However, even when an ID cart or cash card is created using such color printing technology, the ID card or cash card, etc., is partially duplicated and, for example, the name of the person is printed. There is a problem in that by changing the face photo to another person's name and face photo and printing them in color, it is easy to make four such cards, and moreover, it is possible to issue multiple cards in a quantity.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention transfers cyan, magenta, yellow, and optionally black high-density coloring materials from a transfer film to a recording medium by thermal transfer.
After blitting an image consisting of a symbolic photographic image, etc., a mark is placed on the image with a translucent coloring material to the extent that the image is not hidden.

In addition, for this purpose, a card conveying means is connected which sequentially conveys and supplies the cards from a paper feeding means that accommodates a plurality of printing cards and feeds the cards one by one to a thermal transfer printing means and a paper ejection means. Furthermore, the main body of the device is connected to the card conveying means and a card conveying control means that repeatedly moves and stands still at predetermined time intervals, and a device attached thereto has cyan, magenta, yellow, and, if desired, black colors on the surface. Transfer Rf containing a high-density coloring material: a transfer film formed by dividing each of them, and the printing means arranges a head line in which printed dots are arranged in a line along the conveyance direction of the card conveyance means. a thermal line head fixed to the thermal line head; a transfer film conveying means for conveying the film perpendicularly to the conveying direction of the card conveying means by bringing the back side of the transfer film into contact with the thermal line head; A thermal transfer printer having a card stage whose head surface can move up and down so as to bring the card into close contact with the card through the transfer film, and a card stage which can be horizontally reciprocated perpendicular to the transport direction of the card transport means, according to any of the following 2s. It was constructed by modifying it.

The first type has a transparent transfer layer on the entire back surface, and a transparent transfer film with a reversal mark printed with a translucent coloring material to the extent that it does not hide the image is attached, and it is compatible with this transparent transfer film. and a thermal line head in which the roller is slidably pressed in a linear manner through the card and the transparent transfer film to a roller forming a part of the card conveying means, and the transparent transfer buoy trem is attached to the thermal line head. and a transparent transfer film conveying means for conveying the film perpendicularly to the conveying direction of the card conveying means while bringing the surface of the card into contact with the transparent transfer film conveying means.

The other type is one in which a transparent transfer layer is added to the transfer film, in which a reversal mark is printed with a translucent coloring material to the extent that the image is not deposited on the surface.

(Function) According to the thermal transfer printing method of the present invention, 1. A mark is attached to the surface of the created ID card, cash card, etc. with a translucent coloring material, and the card,
The color photograph of the face formed on the surface of the cash card, etc., as well as the date of issue, registration number or certification number, name of the certification authority,
You can see the printed characters, symbols, etc. of the representative's name and the person's name.

When an ID card, cash card, etc. with this mark is copied, the translucent mark cannot be reproduced, so the original and the copy can be easily distinguished by visual inspection.

This semi-transparent mark is made by installing a laminating means on the main body of the device, forming a transparent transfer layer on the entire back surface, and then using a transparent transfer film on which a reversal mark is printed with a semi-transparent coloring material to the extent that it does not hide the image. With this laminating means of a thermal transfer printer equipped with a transparent transfer film,
Alternatively, it can be formed by a thermal transfer printer's transfer film and thermal transfer printing means, in which a transparent transfer layer is added to the transfer film and a reversal mark is printed with a translucent coloring material to the extent that the image is not hidden on the surface.

(Example) The present invention will be explained in more detail with reference to Examples below.

FIG. 1 shows an example of a thermal transfer printer of the present invention, which includes a paper feeding means 1, an encoding recording means 3 for recording a code on a print card 2 fed from the paper feeding means 1, A device main body comprising a thermal transfer printing means 4, a laminating means 5, a paper ejecting means 6, and a cart conveying means 7, and a transfer film 8 detachably attached thereto.

A machine-readable code such as a magnetic coat corresponding to Characters, symbols, and a face photograph are printed on the surface of the cart 2.

For this reason, the thermal transfer printing means 4 has a head line in which printed dots d are arranged in a line along the conveying direction of the cart conveying means 7, and a fixed thermal line head 4a is attached to the thermal line head 4a. A transfer film conveying means 4b conveys the transfer film 8 perpendicularly to the conveying direction of the card conveying means 7 with their back surfaces in contact with each other, and a head surface of the rad 4a transfers the cart 2 to the transfer film 8 to the thermal line.
A card stage 40 that can move up and down in close contact with each other and can move horizontally perpendicularly to the transport direction of the card transport means 7 is provided.
is provided. The surface of the transfer film 8 that comes into contact with the card 2 is coated with high concentrations of black (Bk), cyan (C), magenta CM), and yellow (Y), as shown in Figures 1 and 2 (a). A transfer layer containing a coloring material is formed by sequential fractionation. This order corresponds to the order in which the thermal transfer printing means 4 prints based on the input from the input means. Depending on this order, the arrangement order of the transfer layers containing each coloring material can be changed, and the printing method, that is, the thermal Depending on how the voltage is applied to the printing dots d of the line head 4a, a transfer layer containing a high density coloring material of black (Bk), for example, is formed on one side along the conveyance direction of the transfer film 8, and a transfer layer containing a highly concentrated coloring material of black (Bk) is formed on the opposite side. Of course, it is also possible to use a transfer film 8 formed by sequentially fractionating transfer layers containing high-density colorants of cyan (C), magenta (M), and yellow (Y).

Next, the card 2 on which the image required for a 10 card, cash card, etc. has been imprinted in this way is conveyed by the card conveying means 7 from the position of the thermal transfer printing means 4 to the position of the laminating means 5. A mark 10 is placed on the image of the cart 2 with a semi-transparent coloring material by the laminating means 5.

For this reason, the laminating means 5 has a rad 5a and a roller 7a forming a part of the card conveying means 7, through the card 2 and the transparent transfer film 9, to a thermal line where the roller 7a is slidably pressed in a linear manner. A transparent transfer film mu means 7b is provided which brings the surface of the transparent transfer film 9 into contact with the thermal line head 5a and transports the film 9 perpendicularly to the calligraphy direction of the card transport means 7.

Of course, it may also be formed by doing this.

Finally, this marked card 2 is delivered to the paper ejection means 6
The card 2 is ejected from the main body of the apparatus and a card 2 with a desired mark, ie, an ID card, a cash card, etc., is obtained.

Here, the timing of conveyance from these paper feeding means 1 to the paper discharging means 6, that is, each means is stopped at a predetermined time interval and the process in each means is executed, and then it is transferred to the next means. The timing of movement is automatically adjusted by a card conveyance control means (not shown) connected to the card conveyance means 7.

Then, as shown in FIG. 4, with the above printer, in the thermal transfer printing means 4, the transfer layer of the transfer film 8 conveyed by the transfer film conveying means 4b is brought into close contact with the car 12 and printed on the thermal line by the rad 4a. , a facial photograph 11a, the name of the certification institution, the name of its representative, and the name of the person 11b are printed, and then a certification stamp is attached to a predetermined position on the card 2 by stamping with a seal 12, and a transparent transfer film is conveyed in the laminating means 5. By bringing the transfer layer of the transparent transfer film 9 conveyed by the means 7b into close contact with the card 2 and printing with the thermal line head 5a, a translucent color material mark 10 is formed on the stamped image. Card with the desired markings shown in the figure 2. That is, ID cards, cash cards, etc. can be obtained.

FIG. 2 shows an example of a thermal transfer printer of the present invention, in which the laminating means 5 and transparent transfer film 9 of the printer of FIG. 1 are omitted, and each of the transfer films 8 in the printer of FIG. 1 is omitted. A transparent transfer layer on which a reversal mark is printed with a translucent coloring material is added to the end of the transfer layer, and a semitransparent coloring material mark 1O is formed by a thermal transfer printing means 4.

Therefore, when this transfer film 8 is viewed from the back side, a semitransparent coloring material mark 1O is observed as shown in FIG. 3(b) or (C).

Moreover, when the transfer film 8 shown in FIG. 3(b) is used, the proof 411! The black color in the personal name, the name of the representative, the name of the person, and the photograph of the person's face is obtained by overprinting a mixture of cyan (C), magenta (M), and yellow (Y).

The embodiments of the thermal transfer printing method and thermal transfer printer of the present invention have been shown above. In the thermal transfer printing method of the present invention, cyan (C), magenta (M) and yellow (
A thermal line head is placed through the ink ribbon of each color on which a transfer layer containing a high-concentration colorant of black (Bk) and, if desired, is formed, and after the final transfer process around this drum, for example, a translucent ink ribbon is placed. Of course, it can also be realized by a thermal transfer printer or the like in which a thermal line head is arranged through an ink ribbon on which a transfer layer containing a coloring material is formed.

(Effects of the Invention) As is clear from the above description, according to the present invention, in addition to the effects when ID cards and cash cards are created using the color printing technology already explained in the conventional technology,
