2The charged plating cylinder that enters of low current density, treat in the parcel plating of figure line to increase current density gradually to 4-5A/dm behind the metal
2
The present invention adopts said method, owing to adopted Computer Design and modification, can handle figure line place's wedge angle and edge, and having avoided traditional weave is the clear increase braiding of realization figure line order number, thus the problem that causes some figure line to make; The shape in the hole of the hole version that the use said method is made, density, size can be regulated arbitrarily according to design of figure line and printing demand in unit figure line, present braided wires half tone can't be realized, utilize this characteristic, can be on the anti-counterfeit printing basis of silk screen, the anti-counterfeiting technology that shows unique characteristics that exploitation makes new advances; The mother matrix that method of the present invention is made can be reused, and the metal porous plate that uses on the machine has improved its press resistance rate greatly because of overlay film; Adopt method of the present invention to make metal porous plate, its cost only is 1/10th of similar import braiding sensitization silk screen version or a laser boring version cost.
As seen, adopt the present invention of said method, not only can improve the figure line measure of precision of porous printing and the durability of hole version, and can further improve the anti-counterfeiting performance of porous printing product and reduce the plate-making cost.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Make the method for nonwoven metal porous plate used for printing, be that printing down corrosion technology and plating (casting) plate-making technology are combined and form a kind of method, promptly form the master of production usefulness with the printing down etch, and produce a kind of special through printing forme with this master, realize that accurate figure line mesh changes arbitrarily, with electrodeposited coating as every China ink layer, thereby replace the printing block of traditional braided wires half tone.
The concrete steps of said method are:
A. design on computers has the pressing of the metal porous plate of figure line;
B. above-mentioned pressing is sent a manuscript to the compositor by the film setter that is connected with computing machine and made branch version film;
B1. the figure line on minute version film is checked, will be checked out that undesirable part repairs on computers then, as the wedge angle at figure line place and burrs on edges etc.;
C. prepare mother matrix version base, on the mother matrix version base of making metal porous plate, be coated with photoresists;
D. above-mentioned branch version film is covered on the mother matrix version base that is coated with photoresists and carry out printing down, develop then, pressing is presented on the photoresists;
E. after treating that photoresists are aging, corrode mother matrix version base, make the mother matrix of metal porous plate with above-mentioned figure line;
F. earlier to the mother matrix processing of coming unstuck, again mother matrix is checked and repaired, clean up mother matrix and water spacer pad, electroplate by mother matrix then and make the hole version, to this hole version overlay film, by laser carving method the overlay film at the place, hole of biting of figure line is removed again, make the metal porous plate that the machine printing is used.
The temperature that the material that adopts in the above-mentioned overlay film process generally is a thinner thickness, ability is certain (60 ℃), certain stretch-proof deformability, any surface finish (roughness is less than 2um) are arranged, and the material that under the burning of laser, can gasify.Among the embodiment, what adopted is the preceding shelves blow-out disc of vehicle glass.
