Abstract

The present invention relates to a kind of simple PS version production technologies used in a kind of printing PS version method for platemaking, it is characterized in that (1) the PS versions surface of aluminum plate has the Grains through electrochemical milling roughening treatment, (2) the PS version surface of aluminum plate has the AL of anodized2O3Oxide layer.

Description

A kind of simple PS versions production technology used in printing PS version method for platemaking
First, technical field
The present invention relates to the simple PS versions production technology used in a kind of printing PS version method for platemaking.
2nd, background technology
The PS versions that present offset press uses, are all the PS versions with photosensitive layer, with the raising of computer printout precision, we It is entirely possible to substitute CTP to make a plate with printer, being exactly the advantages of printer printing PS version plate-making in PS versions need not be photosensitive Layer, directly print can on hydrophilic layer with printer and complete the plate-making of PS versions, simplify plate-making program, reduce cost, carry High quality, saves the time, the technology is the trend of PS versions plate-making future development.
3rd, the content of the invention
Electrochemical milling processing is carried out to surface of aluminum plate, forms roughened layer；
Oxidation processes are carried out to surface of aluminum plate, form AL2O3Oxide layer.
4th, specific implementation method
The processing of electrochemistry nog plate：Make the process that surface of aluminum plate produces Grains we term it nog plate, also cry electrolysis, be roughened or Corrosion, we are put into nitric acid electrolyte PS versions processed with the aluminium sheet of 300 micron thickness, then ibid alternating current, voltage 30- 100V, current density 20-150A/dm2, aluminium negative half period H+- ＞ H2, are so alternately repeated in positive half cycle AL- ＞ AL3+, when Between be the 6-60 seconds, so as to form the small pits of various 1-20 microns, referred to as Grains on aluminum surfaces；
Anodic oxidation：By electrochemistry nog plate treat aluminium sheet, be put into anodic oxidation electrolyte, electrolyte by sulfuric acid, Malonic acid, oxalic acid, glycerine composition, then to lead to upper direct current and carry out anodic oxidation, voltage is 30~100V during above-mentioned anodic oxidation, Current density is 2.5~3.0A/dm2, and processing time is 50~300min, and treatment temperature is 15~21 DEG C.
By said process, we have just made simple PS versions, and the version has double-layer structure, and one layer is aluminium sheet, and one layer is band sand Purpose oxide layer.

Claims (2)

1. a kind of simple PS versions, it is characterised in that there is the roughened layer through electrochemical milling processing and oxidation in PS version surface of aluminum plate The AL of processing2O3Oxide layer.
2. aluminium sheet described in claim 1 is the thick cold-reduced sheet of 100-400 microns.
