Problems solved by technology

[0005] However, due to the low printing durability of the screen plate determined by the screen plate material and the general-purpose plate-making process, there is a huge difference between the printing durability of the printing plate currently used for banknote printing. The assembly line is composed of a large printing process. According to the 1:1 configuration of each type of printing machine, it can be matched only in terms of the speed of the printing machine.
However, due to the low printing durability of the screen plate, it takes a long time to stop the machine and change the plate, so it is difficult to balance the production of the assembly line
According to the survey, the general polyester silk screen has a print life of tens of thousands of prints, and the lowest one can only print a few thousand prints, and it is difficult to reach more than 100,000.
[0006] In addition, although the screen plate-making process has been greatly improved, it is still not separated from the traditional photochemical combination plate-making process of the photochemical film-forming method, so that the printing durability of the screen plate still depends on the screen-sealed photosensitive adhesive. The fastness of the screen plate is difficult to have a big breakthrough

Embodiment approach 1

[0030] Such as figure 1 As shown, the metal stencil proposed by the present invention includes a metal plate 1, on which an ink penetration hole 11 is provided, on the metal plate 1 and outside the area of ​​the ink penetration hole 11, a lining area 12 is opened, and the lining The area of ​​the plate area 12 is larger than the area of ​​the ink penetration hole 11, and the lining area 12 and the ink penetration hole 11 are distributed in steps.

[0031] Because the stencil of the present invention uses metal as the plate material, the printing durability of the stencil is greatly improved; due to the stress around the ink penetration hole, the stencil is prone to deformation during printing, so the present invention is still in the region of the ink penetration hole 11 A lining area 12 is set outside to increase the support for the ink penetration hole 11, and at the same time facilitate the flattening of the stencil to avoid deformation of the stencil, thereby improving the...

Embodiment approach 2

[0036] Such as figure 2 As shown, the manufacturing method of the metal stencil that the embodiment of the present invention proposes, it comprises the following steps:

[0037] Such as figure 2 As shown in (a), a stencil punch 2a1 is provided, and the punch 2a1 has more than one step 2b, here there are two steps 2b, and a plurality of bumps 2c are provided on the top of the step 2b; wherein, the punch 2a1 can be placed on the bottom support 2a2, and the convex mold 2a1 can be a nylon convex mold, such as alcohol-displaying nylon convex mold.

[0038] Such as figure 2 As shown in (b), the metal intaglio body 2d is turned over by the punch 2a1, and the metal intaglio body 2d forms a step-like lining area 12 corresponding to the above-mentioned step 2b, and forms a non-penetrating ink penetrating area corresponding to the above-mentioned bump 2c. Blind hole 11', that is, the ink-through blind hole 11' at this time is not a through hole, but a blind hole. The area of ​​the ...

Abstract

The invention discloses a metal porous plate and a preparation method thereof. The metal porous plate comprises a metal plate which is provided with ink through-holes, a plate lining region is arranged on the metal plate outside the ink through-holes, the area of the plate lining region is larger than that of the ink through-holes, and with the plate lining region and the ink through-holes are distributed in a stepped way. Because the metal porous plate is made from metal, the printing rate of the porous plate is greatly improved; because the porous plate is easy to deform in printing under the stress effect around the ink through-holes, the region outside the ink through-holes is further provided with the plate lining region to increase the support to the ink through-holes, be beneficial to stretching of the porous plate, and avoid the deformation, therefore, the printing quality is increased. The invention further discloses a method for making the metal porous plate.

Description

technical field [0001] The invention relates to a metal stencil with good printing durability and a manufacturing method thereof. Background technique [0002] Screen printing is to place the screen on the printing part of the printed matter, use a plastic plate to squeeze the ink, and the ink is extruded on the surface of the printed matter through the mesh. [0003] Banknote printing is different from general commercial printing. In addition to special printing process and high anti-counterfeiting function, the most notable feature is the large printing batch. The printing number of a banknote is calculated in units of tens of billions. In terms of the time span of printing, the "printing process" of a bond type can range from a few years to more than ten years. In the production process, after the new and old printing plates of the same type of coupon are replaced, the plate pattern and ink color of the printed product cannot be clearly seen from the eyes to see the diff...
