SU37718A1 - Printed form for multi-color printing on paper, fabric, leather and other materials with one print - Google Patents

Description

The proposal relates to a method for producing a printing plate for a multi-color "amati" print. In the main author's office for No. 37712, it is designed in the form of a filigree installed on a layer from a war, paraJiHHa and the like material, in order to gradually crush face fillers into a plate from warrior as the paint layer is consumed from the surface of the printing form during printing. The proposed improvements in the manufacture of such printing forms are aimed at obtaining the forms that are the most durable and at the same time giving the possibility of obtaining uniform prints.

In FIG. 1, 2 and 3 show printed filigree form in a perspective view; heck. 4 is a sectional view of the printing plate along the PQ line in FIG. 3; FIG. 5 and 6 - details of the shape of the leHEiH parts of the form; FIG. 7 and 8-perspective view of the form according to the second option; FIG. 9, 0 and 11, the first version of the device to protect the lines of the pattern from de Generation; FIG. 12 to 13 is a second option for the same purpose.

For a multi-color print and for a pack of flowers, a rigid metal etalon made of thin and rigid metal bands placed on an edge (t of fig. 1 and 4) from (waist, phosphor bronze; duralumin, copper, etc.) is made precisely along the lines of the reproduced pattern. connected at its intersection a-cross grooves a (fig. 5) and in some cases of meshes.

This rigid mesh connects with a sturdy

metal angular or strip iron angles) with an external frame AAi (Fig. 1) of any shape, corresponding to the figure of the original, and thickness values, depending on the length,; gtlotppdp reproducible pattern, the height of neso.l. more than the height of the indicated stripes, with a sharpening of the difference in height and the lower edge of frame b (Fig. 6). The joint is made firmly by punching into the paxte with the inner side of the grooves for placing at the ends of the grid lines that are in contact with the frame. These ends are inserted into the grooves, pressed into them with the talical pressure of the press flush with the super-lower surface of the frame and fixed in the grooves with (Fig. 1 and 6). In the case when the lines of the pattern are far from each other or from the outer frame of the filigree, they are fastened between themselves and with the outer frame of jumpers from straight steel strips a few millimeters already. Consequently; below the upper surface of the cliche, as a result of which they do not affect the pattern. The bottom edges of the jumpers are tapered.

Tough metal mesh and durable. The effective outer frame, connected together in this way, form rigid and stable truss lines in the form of AA F filigree (Fig. 1), which are not defined when printing or stuffing NK fabrics in vertical or horizontal directions.

According to the rigid filigree described above, the etv from the solidified mass is a solid matrix (fng. 2) as follows. A horizontal attachment of the horizontal polished plutt - matrix matrix CCi clade is ready for filigree LL, the lining and filigree are pre-lubricated with a special ointment, preventing adhesion of the lining and the farm of the filigree with a hardening mass, and bordered with an outer, open metal frame, with a hardened, external, open-frame metal frame and a hardened mass, surrounded by an external, open metal frame, are bonded with a hardening mass and surrounded by an external, open metal frame.

The dummy ferrule and filigree are filled (ia with a solidified mass D (Fig. 2) and placed under a press. By means of a vertical press, the mass enters all the nests of the filigree grid and fills them and the whole matrix shell exactly to the height of the craz of the latter, forming two horizontal; parallel, smooth matrix surfaces.

When the mass hardens sufficiently and engages with. with a non-lubricated BBi matrix padding, ready to separate firmly from the paddle, and that and the other is completely dried off the ointment. Then the solid matrix is re-deposited on the lining, but in the inverted form, the rigid filigree is removed from the solid matrix, forming the last grooves / (Fig. 2), completely identical to all the lines of the grid and the outer frame of the rigid filigree (depth, equal to the width of the metal bands of the filigree grids itolizdinnevnyeramy filigree).

A solid matrix made by the above method is superimposed (and slightly glued) thin, impermeable to paints, a paper layer, waxed or an oiler, and so on. (Fig. 3 and 41. The vertical planes of the grid and the filigree frames and the matrix grooves are smeared with a special ointment for easy sliding of the entire filigree truss when immersed in the matrix grooves, then the filigree is laid on the non-impacted core layer along the exact lines of identical matrix and solid matrix. light vertical pressure is slightly pressed into the grooves of the matrix, cutting through the impermeable layer and forming closed nests k, I, t, p.o, p filigree setfig. 3 and 4).

When the layer is cut through and the hard filigree is pressed into the matrix, the cut edges of the layer intervene slightly in the matrix grooves, and the entire filigree farm tightly enters them, which prevents the colors from penetrating into the matrix grooves when printing or stuffing cliche.

Thus, a hard filigree, hard matrix to the impermeable to the interlayer paints are combined into a single form of a multi-color cliche.

Formed nests /, t, n, o, and a small filigree are filled with paints of different chemical composition and different texture (depending on the desired type of multi-color printing or fabric printing), equalized on the upper surface and vertical pressure of the press are reduced to the level of the upper edges frames to the filigree mesh, acquires a smooth mirror surface.

FIG. 4, a section of the obtained multi-color cliche is shown with an index of the matrix lining C, the LH matrix lying on it, with grooves l identical to the external section

filigree frames and cuts of filigree grid lines t. lying on the matrix H, the perforation 1: the second layer of the E C is cut by the edges V of the f-edge, which enter a little into the grooves of the matrix I- and the nests of the f, n, n, and filigree mesh filled with different colors.

In order to give the greatest stability to all lines of the pattern, i.e., tonggim metal nolosam filigree mesh, the latter should, in addition to the mutual bonding of lines between them crosswise grooves and, partly, soldering, fixed on the bottom tape A with Jumpers a (Fig. 7 and 8), which are made of thicker and stronger metal strips, for example, steel, than the grid lines of the &pattern; in filigree f. The strips a are fastened together crosswise into the grooves and, thus, form squares of various sizes, depending on the complexity of the drawings.

The cassette L is firmly attached to the filigree frame / by pressing the end of all the lines (jumpers) into their corresponding slots from the core walls of the core, cemented, soldered and so on.

In order for the whole farm to filigree lines. so on its frame to the jumper line and from the figure h could be taken out of the hardened mass D of the matrix L-T. The upper cassette 5 was inserted from the strips d. They are the same in height and squares of the same material as the lower cassette A. The upper cassette B is fastened to the ferrous lines of the pattern b as well as the lower cassette A. in the groove before the casting of the matrix / L along the filigree F. After the solidification of the mass D from it removes the entire system of the filigree lines F, i.e., the frame, the grid of the lines of the pattern B n together the lower and upper cassettes A n B. and in the solidified mass D there are grooves for each of the lines.

By knockout (| or face F, the lining line of the pattern b is taken away from the A T B cassettes, then the upper cassette -B is taken away from the bottom / 5. And the L linewidth of the b drawing is put on again}: on the lower cassette A and is permanently attached to it. After that the entire filigree / is lowered several times into the grooves of the matrix M and is raised again to establish a completely unimpeded immersion of the filigree into the grooves of the matrix during printing.

Both the filigree frames f- and the cassettes, lower A and upper B, are made aarae, with the frames in sizes of typical printing plates, and the A and B cassettes with squares of several sizes, depending on the simplicity of the pattern complexity,

If necessary, the xapaicTopy lines of the junction and these or other sections of the jumpers can be cut off, and the ends of the jumpers that remain in place and are soldered by the lines of the pattern.

A cassette A with jumpers a can be made immediately to the whole grid height. The patterns of the fr pattern, as indicated in FIG. , without the additional upper cassette B. In this case, the top part of the strips / cassette is sharpened before filling the filigree with paints.

In order to avoid when pressing a drum of a lithographic or typographical machine on a multicolour MF when printing any harmful play of filigree F in the grooves of matrix M and deformation of lines of pattern f, firstly, the frame of filigree F is made much higher than the height of the lines of the pattern t and, secondly, special safety guards P in two versions are attached to the filigree f.

Option (fng. 9-11). In the filigree F, cuttings d (3-5 mm) are made in several rows of gradual, 1 mm or less, cutting drops cutting d, with stops at the bottom and with inclined planes upwards.

Fuse P is screwed to the matrix M and has grooves inside, corresponding to the movable locking teeth, and located at the same height. Springs b are placed in the slots. The teeth, if necessary, are secured to the fuse P with the clamping bolts c.

Accordingly, the teeth in the matrix and the solid mass D are drilled holes in which the tooth moves, and when the spring is pressed with its own pointed tips and the corresponding cuts d, are included in these cuts.

Option II (Fig. 12 and 13). The described cuttings d by ladders, with a drop of 1 quintal less, are made on plates A prefabricated, KOTOfibie is screwed in the right places to the frame of the filigree F. The fuses P are the same as in the first variant, with the sharp ends of the locking teeth a and H { . coincide with d slices on plates A.

The fuses P are installed on all four sides of the clip M in the right quantity.

According to the installation, according to the second variant, plates A cha. frame filigree F or on the first wa; And the notches on it are d, all the notches are smeared to a smooth surface, and after that the matrix M is cast on the filigree F

When the filigree F is taken out of the matrix M, the putty is removed, and the cuts d are cleaned.

By the filing of the filigree, the impermeable layer II filling its /, i.e., paint-and-gigall locks and the locks P in the fuses P are released, and under the pressure of the springs b part of them enters the cuts d.

When printing, when the frame of the filigree F is in contact with the drum of a lithographic or typographic machine and with its pressure on p; F, the opposite end of it and the whole system of filigree lines tend to rise and can get out of the grooves r, but this is prevented: - first, the elongated walls of the filigree frame F, abutting at the slightest deviation from the vertical into the walls of their grooves r in the solid mass D of the matrix M, and secondly, those in the locking teeth, which at any given moment fit tightly into the thread d, and horizontal cuts, resting against the horizontal lower parts of the teeth, do not allow the frame of the filigree F to rise, and hence the entire network of lines of the pattern f fixed in it, i.e. the entire system of the latter remains calm and protected from deformation.

The gradual fall of the ladder cuts d, pa. I mm n less, and the location of the fuses P and cuts .d in several places.

on all four sides of the filigree F mattress M, guarantees from the entire rise of the festival over the entire area of the cliché. To lower the entire filigree P into the grooves r, there is no obstacle when printing and pressing the drum of the machine, due to the sliding of the bevels at the ends of the locking teeth a along the inclined planes of the cuts d.

The multicolor cliche manufactured by the above method is put into a printing or ka-plw machine with vertical pressure (hydraulic-lever, eccentric), and the process of printing or stuffing the fabric is as follows: a) gradual and regular imposition of printing objects or printing on the multicolor cliche; b) in a regular and even (but a pressure gauge) press pressure, c) in a smoothly all over plane cliche impression of colors on printing objects and. and stuffing, due to the complete resistance of the solid matrix to the immersion of the paint layer in it, to prevent impermeable layer vpt; dyeing paints into the mass of the matrix, d) in the same way, free and easy immersion of the same Koi of the filigree in identical grooves firmly: the removed paint layer, with negligible opposition to such an immersion, only a trench of lubricated sliding vertical surfaces of the outer frame and filigree networks the smeared walls of identical; im matrix grooves; e) in the free and easy immersion of the filigree i: matrix holes until full use of the entire ink layer of the cliche during the furnace; 1T 1 or fabric pamping.

The subject matter of the invention.
