Multicolor seal and stamp

FIELD: multicolor printing methods.

SUBSTANCE: method involves transferring positive image formed on film onto carbon-treated microporous rubber; dividing portion of microporous rubber of, for example, round shape, which had not been subjected to pulsed light treatment, into n number of sectors of different shapes; creating boundaries between sectors by exposing microporous rubber to thermal action of maximal depth. With 1.5 mm thick rubber, depth of boundary shall be at least 1.1 mm and shall not exceed 1.4 mm, said depth preferably approximating to thickness of rubber. Upon subjecting rubber to thermal action, pores are caked to define boundary, which protects sectors from mixing of inks of different colors. Resultant sectors are further charged with inks of different colors.

EFFECT: provision for creating of high-quality multicolor print.

The technical field to which the invention relates.

Multicolor printing, and stamps can be used in the proceedings in the case of certification, or the identity of any documents, as well as one of the ways to protect them. Multicolor printing and stamps allow you to put a serious barrier to counterfeiting seals.

Such seals cannot be forged.

The level of technology

Existing technology seals allow you to create a seal of any one color. In our case, in the manufacture of printing on "flash" technology, first created the original print layout on the computer, which is then printed on a laser printer on the film, i.e., creates a positive image printing on film. This ends the first stage.

In the second stage, this positive image is transferred to the treated carbon microporous rubber. With the help of powerful light pulses, i.e., blowout rubber, its pores are sintered. Open only remain pores, which imposed a positive image, due to the fact that the toner of this image prevents the rubber baking. This ends the second stage.

At the third stage, the processed tires dressed with ink of any one color and can be left on the paper seal of the color, how it was filled rubber.

This technology is otopleniya seals are already known. Rather the details of this technique are described in the article Vratnica "New Japanese technology seals in the Russian market", published in the journal "FLEXAPLUS, No. 5, October 2000.

Disclosure of inventions

The basic idea of the invention is to create a multicolor print on paper. Part of microporous rubber round shape is processed by the above two stages. In fact, the method of manufacturing a multicolor printing is that you first create an original print layout on the computer, and then printing the print image on the film by a laser printer. While one side of the rubber, which overlay printing on film, processed, powerful light pulses, and the raw part is divided into sectors of different forms, among which are the boundaries by sintering pores of microporous rubber under thermal influence on almost the whole of its thickness.

The invention consists in creating boundaries between these sectors, which do not allow to mix paints of different colors, ie, for example, red paint first sector will not be mixed with blue paint in the second sector, which have one common border. The blue paint of the second sector will be mixed with purple paint of the third sector and so on. the pages in between sectors are created by the method of thermal effects on microporous rubber in as much depth. So, when the thickness of the rubber 1.5 mm depth boundaries shall be not less than and not more than 1.4 mm, and ideally should be close to the thickness of the rubber itself. Thus, thermal effects on the rubber, the pores are sintered, forming the border, protecting the sector from the mixing of inks of different colors.

At the third stage, we made the sector are filled with inks of different colors. Each sector correspond to certain elements of the graphical image printing. All sectors, taken together, constitute a single unit graphics printing. The product is ready for use. On paper appears multicolor graphic image.

Brief description of drawings

The drawings show a printing round shape (figure 1 and figure 2) and the stamp (figure 3) in the form of a rectangle, and also shows the boundaries of the sectors to which they are broken (items 1, 2, 3, 4 in figure 1 and items 1, 4, 5, 6, 7 in figure 2, items 1, 2, 3, 4, 5 in figure 3).

At the disposal of the author of the invention there are several existing experimental samples multicolor stamps and stamp impressions which is shown in figure 4.

A method of manufacturing a multi-color printing, consisting in the fact that you first create an original print layout on the computer, and then printing the print image on the film on a laser printer, characterized in that one side of the PE the ins, which overlay printing on film, processed, powerful light pulses, and the raw part is divided into sectors of different forms, among which are the boundaries by sintering pores of microporous rubber under thermal influence on almost the whole of its thickness.
