Abstract

Use: replication of line images, such as book marks. SUMMARY OF THE INVENTION: Aluminum foil 0.1 mm thick with a pre-printed pattern rolls over a layer of plastic material and imprints a pattern with a recess of 1.0-1.5 mm. A frame is laid on the foil and fixed, and the epoxy resin is poured into the frame and held until it hardens.

Description

The invention relates to a process for the manufacture of forms for flat printing and can be used when it is necessary to replicate line art, such as book marks.

A known method of making decals of multiple uses, including photocopies of the original decal onto a film, dekolkopir film, film processing and dyeing;

The disadvantage of the known method is the complexity of the method of manufacturing the mold.

A known method of making a flat printing mold consists in coating a substrate with a layer of silicon resin, vulcanizing this layer, applying an oleophilic image, and applying an adhesive polymeric material to the substrate before applying the silicon resin on the substrate. particles of the electrographic developer before they penetrate into the adhesive polymer material, and the oleophilic image after pressing is melted and after pressing the oleophilic image the particle, the developer is removed.

The disadvantage of the known method is the complexity of the method of manufacturing the mold.

The purpose of the invention is to simplify the method of manufacturing a form for flat printing.

This method is achieved by applying a layer of plastic material to a flat rigid plate, for example wax, plasticine, shoemaker, a layer thickness of 1.5-2.0 mm, aluminum foil with a thickness of up to 0.1 mm is rolled over a layer of plastic material a print with a blunt object on the foil makes an impression of a pattern with a recess of 1.0-1.5 mm, after which

A frame is superimposed on the foil and fixed, and a fast-hardening material, such as butacryl-sterocryl, is poured into the frame, and is held until hardened. The proposed method of manufacturing a flat printing mold is characterized in that an aluminum foil with a thickness of up to 0.1 mm with a pre-printed pattern is rolled over a layer of plastic material, an image with a recess of 1.0-1.5 mm is printed on the foil, after which the foil is applied the frame is fixed, the fast-hardening material is poured into the frame and is held until hardened.

A method of making a form for flat printing is carried out as follows.

A layer of plastic material is applied to a flat rigid plate, for example wax, clay, shoe varnish, thickness of 1.5-2.0 mm. A material having deep-drawing properties, for example aluminum foil up to 0.1 mm thick, is rolled over the layer of plastic material. on which the image is pre-printed. Then a thin hard object with a blunted end makes an imprint of a pattern with a recess of 1.0-1.5 mm, after which a frame is laid on the foil and fixed. A rapidly hardening material, such as butacryl-sterocryl, is poured into the frame and held until it is completely cured. After za0

material hardening the frame is removed and separated from the hardened mass. The resulting form can be refined - corrected (if necessary) the difference in strokes, the width (by grinding the engraving on a thin abrasive cloth, stretched on a flat surface).

Using the proposed method of making a mold for flat printing, simplicity of manufacture is achieved, low cost of manufacture, high productivity of mold manufacture.
