Abstract

A method for printing paper that is used for computer printouts, prints clearly has good type adherence, and a printed layer and prevents photograph slippage. This method comprises (1) making space for printing an item; (2) coating the printing paper with a solution composed of poly vinyl alcohol powders(5g), toluene(50cc), and aceton(100cc); (3) drying the printing paper; (4) writing an item by computer; (5) coating the photographic space with an exposure solution to print a photograph. In the treatment of the computer paper, mixing ratios of poly vinyl alcohol, toluene, and acetone are very important.

Description

Processing method of computer printing paper for anti-counterfeiting proof

The present invention relates to a computer printing paper for anti-counterfeiting proof. Conventional automobile driver's license, such as a base sheet paper should be typed one by one with a special ink on a vinyl paper, and in the photo column was formed by the adhesive layer, the photosensitive liquid was applied to print the photograph.

Applicant of the present application is a general computer printing paper printed with a personal information sheet in the process of studying a problem of automatically printing and issuing by a computer without the inconvenience of having to type personal information into a special ink one by one. After printing the descriptions by the computer with the printer of the computer and print the photo by applying a photosensitive liquid to the photo field.

When washing with a printing solution, the printing paper was swelled with water, the printing layer and the photo layer were peeled off, and it was impossible to use the certificate for preventing the counterfeit.

Therefore, in order to issue the anti-counterfeiting proof to a computer, first print the description column on the computer printing paper in the usual way, and then print the computer on the personal information field of this paper, and then print the paper in the printing process. It should not be shrunk or stretched afterwards, and the processed print paper cannot function even if there is a minute error requiring ultra precision.) Printing should be possible with a computer, and the processed print paper should be printed on the computer print ink. The results of the experiment proved that printing is possible and at the same time the printed print should not be erased.

The inventors of the present invention have been conducted to solve the problems of computer printing of the anti-counterfeiting proof personal information base paper as described above, and the invention has been developed a method for treating a printing paper for a computer satisfactory. same.

Print the proof information on the printing paper by the usual method, dissolve 5g of polyvinyl alcohol powder in 50cc of toluene, immerse 100cc of acetone in the mixed solution, infiltrate it, dry it, and hang it on the computer to write the proof information. Was printed by a computer, the photosensitive liquid was applied to the photographic field by the usual method, and the photograph was printed to produce a driver's license for preventing forgery by welding the main surface at high frequency by inserting vinyl between the surface.

The blending ratio of polyvinyl alcohol, toluene and acetone is very important in the processing of the computer printing paper of this company. If more polyvinyl alcohol is added, the computer printing and photo printing are not possible, and if the amount of toluene and acetone is increased, the printed matter becomes It is erased.

Printed papers processed as described above have almost no shrinkage or elongation, which enables computer printing that does not allow for minute errors, as well as print and photo prints, which are clear and have good adhesion, so that print layers and printed pictures do not come off. will be.

In addition, by using the paper of the present method, it is possible to issue the anti-counterfeiting certificate to a computer, and there is no need to separately form the adhesive layer applied to the conventional photograph column, so that the anti-counterfeiting proof can be issued very simply and efficiently.

Since the paper treated by the present invention has almost no shrinkage or elongation and is water-resistant, it can be very effectively used in the field of the right field such as military operation map or cadastral map in addition to computer printing paper for anti-counterfeiting proof.

Claims (1)

As described above, 5g polyvinyl alcohol is dissolved in 50cc of toluene, and then 100cc of acetone is added thereto so as to immerse the printing paper in a solution having a mixing ratio.
