Template printing form

FIELD: polygraphy, in particular, template printing forms.

SUBSTANCE: template printing form has meshed base and photo-resistive parts, limiting printing elements. Meshed base consists of cells in form of scalene n-angled shapes of even areas, where n≥3, positioned irregularly. Lengths of links, forming sides of n-angled shapes, are selected from condition of evenness of areas of these.

EFFECT: increased printing quality due to prevented appearance of moire pattern, appearing because of interference between regular polygraphic dot matrix and meshed base.

The invention relates to printing, in particular screen printing forms.

Well-known screen printing form, which can be manufactured using the method specified in patent RU No. 2222037.

Well-known screen printing form contains a grid, stretched on a frame. The disadvantage of screen forms is the inability to use it in rotary screen printing.

The closest in technical essence to the declared object is a well-known screen printing a form with a net basis and photoresistive part, limiting the printing elements [RU No. 2213666].

A disadvantage of the known screen printing plate is a moiré pattern resulting from interference between the regular printing a raster and a net basis, which reduces the print quality.

The objective of the invention is to improve the print quality.

This task is achieved by the fact that in screen-printed form, with a net basis and photoresistive part, limiting the printing elements, according to the invention netted base consists of cells, which is a versatile n-squares of equal area, where n≥3, spaced irregularly, and the length of the crosspieces that form the sides of the n-squares selected from the condition of equality of the areas of the latter.

The essence is subramania illustrated by drawings, which figure 1 shows an example of a mesh consisting of triangular cells 1 formed by jumper 2. Figure 2 shows an example of a mesh consisting of cells 1, consisting of versatile quadrangles formed by crosspieces 2 and photoresistive parts 3.

Mesh-based screen printing plate made of a metal foil or polymer film. Net framework is a cell in the form of diverse n-squares of equal area, for example a triangular or quadrangular shape (Fig.1, 2). For each mesh base n=const. Cell mesh base separated by jumper 2. On the surface mesh base in any known manner to form photoresistive part 3. Thus, the result is an irregular net basis.

The proposed stencil printing plate can be performed by means of chemical etching, laser engraving, electroplating, deposition, or other known method.

The proposed screen-printed form can be used in flat and rotary screen printing.

Between net basis and regularly spaced photoresistive parts interference does not occur, as a consequence, no moire, thereby improving print quality.

Screen-printed form with etcatu basis and photoresistive part, limiting printing elements, wherein the netted base consists of cells, which is a versatile n-squares of equal area, where n≥3, spaced irregularly, and the length of the crosspieces that form the sides of the n-squares selected from the condition of equality of the areas of the latter.

SUBSTANCE: method for manufacture of template for application of pattern on item includes manufacture of template on sticky transparent polymer film, which has been previously glued to glossy surface of base, for instance, glazed paper, hardness of the latter is higher than hardness of polymer film, and colours contrast with each other. Template is manufactured by cutting of windows along the circuit of applied pattern. Film pieces are removed from prepared cuts of windows to arrange template, which is fixed on top by the second polymer layer from sticky stripping film. Paper base is removed from the opposite side of template, and template is glued on item with open sticky side. Then stripping film is removed from external side of template, and pattern is applied through template windows.

EFFECT: higher convenience and quality of inscriptions or patterns application on flat items.

SUBSTANCE: invention is related to galvanoplastics. Matrix for galvanoplastics of printing screens includes matrix plate, on which metal is deposited for moulding of printing screen. Matrix plate includes the main surface of deposition, on which metal deposited to create the main body of printing screen, at least one pair of edge segments at the opposite borders of the main deposition surface, which include edge segments of deposition, which come out from plane produced by the main deposition surface, on which metal is deposited to create fastening elements of printing screen, and angular sections in appropriate angles of deposition surface. Matrix also includes non-conducting elements in the form of edge elements, which are located at edge sections so that they create length of these edge sections, and non-conducting elements in the form of angular elements, which are located near angle sections so that they protect them and create length of the main deposition surface near these angular sections.

EFFECT: expansion of assortment of produced items.

SUBSTANCE: method of screen printing of a high resolution image on a substrate is provided, in which a stencil sheet is used with a system of holes separated by partitions and points of intersection, having a flat surface on the scraper side. The stencil sheet on the printing side is provided with a three-dimensional structure comprising projections and recesses formed by the difference of the thickness between the partitions and the points of intersection, and the pattern facing the substrate and representing a mute negative of the image to be printed, and according to the method the ink is deposited on the substrate, thereby forming the image with a resolution of less than 100 mcm.

EFFECT: method of screen printing of high resolution image on the substrate is proposed.
