Abstract

A manufacturing process for a printing lithographic plate comprises the steps that a layer of nickel is plated on a roller blank which is a steel pipe; a first layer of copper is plated on the nickel; the first layer of copper is coated with a layer of Ballard developing solution; a second layer of copper is plated; engraving platemaking is carried out on the second layer of copper; a layer of chromium is plated after engraving platemaking; and the pattern part on the roller blank is cut off after chromium plating and then pasted to an aluminum plate, and therefore the printing lithographic plate is obtained. Compared with roller gravure, the number of steel pipes needed during manufacturing of printing rollers can be reduced according to the lithographic plate, and waste of ink and printed materials of a printing house during sample making can be reduced; environment pollution which occurs due to the fact that residual materials of the printing house cannot be recovered after printing can be reduced.

Description

The manufacture craft of printing lithographic plate

Technical field

The present invention relates to printing technology, particularly a kind of manufacture craft of printing lithographic plate.

Background technology

The intaglio printing of prior art all adopts columnar roller, and the Making programme of roller is on steel pipe, plate one deck nickel, then copper facing on nickel, then engraving, chromium plating.When client needs to see printing sample, printing house must make roller, then print on track, but this kind of method cost is high, and the finished product printed, and client only sees portion, all the other print additional can only slatterning, for some PET, PVC, OPP materials, it cannot be recycled, also very serious to the pollution of environment.

Summary of the invention

Object of the present invention, exactly in order to provide a kind of manufacture craft of printing lithographic plate, to solve, the number to be printed that printing house's early development produces is large, the phenomenon of waste.

The object of the present invention is achieved like this: a kind of manufacture craft of printing lithographic plate, comprises the following steps:

A, be roller stock with steel pipe, roller stock plates one deck nickel;

B, on nickel, plate ground floor copper;

C, on ground floor copper, be coated with one deck Ba Lade developer solution;

D, plate second layer copper again;

E, engrave on second layer copper;

One deck chromium is plated again after F, engrave;

G, plated chromium after the pattern part on roller stock is cut, paste on aluminium sheet, obtain print lithographic plate.

The thickness of described ground floor copper is 0.01-0.02mm, and the thickness of second layer copper is 0.14-0.16mm.

Compared with roller intaglio plate, lithographic plate not only can save required steel pipe when making roller, and (steel pipe can repeatedly reuse, and the girth of roller can not be confined to), and the waste of ink that printing house causes when drawing a design and stock can be reduced, more can alleviate printing house and cannot reclaim and pollution on the environment for excess stock after printing.When client needs to see printing sample, only need print according to customer requirement number, can not produce unnecessary waste, and after completing, roller embryo can reuse, cost-saving, favorable environment is protected.

Detailed description of the invention

The present invention prints the manufacture craft of lithographic plate, plated nickel on steel pipe after, nickel plates end copper that one deck 0.01-0.02mm is thick again, then on end copper, be coated with one deck developer solution (Ba Lade liquid), and then copper facing, engraving, chromium plating, after having plated chromium, pattern part in roller is cut, then pasted on aluminium sheet, make lithographic plate.

Compared with roller intaglio plate, lithographic plate not only can save required steel pipe when making roller, and (steel pipe can repeatedly reuse, and the girth of roller can not be confined to), and the waste of ink that printing house causes when drawing a design and stock can be reduced, more can alleviate printing house and cannot reclaim and pollution on the environment for excess stock after printing.When client needs to see printing sample, only need print according to customer requirement number, can not produce unnecessary waste, and after completing, roller embryo can reuse, cost-saving, favorable environment is protected.
