Embodiment Construction

[0010] A method for manufacturing a pre-coated photosensitive plate for printing in the present invention is achieved in this way. It is formed by bonding and compounding an aluminum foil layer and a plastic layer through an adhesive layer. roughened layer and anodized AL 2 o 3 Oxide layer, in AL 2 o 3 A photosensitive resin layer is directly coated on the oxide layer. The thickness of the plastic layer is 0.1-0.3mm, and the thickness of the aluminum foil layer is 0.02-0.15mm.

[0011] The precoated photosensitive plate of composite plate base of the present invention is realized according to the following steps:

[0012] 1. The aluminum foil plate is anodized according to the conventional surface electrochemical method, and coated with a positive photosensitive resin solution to make a thin aluminum-based PS plate;

[0013] 2. Composite the thin aluminum-based PS plate with the plastic layer coated with adhesive.

Abstract

The invention relates to a preparing method for a precoating photosensitive plate which is used in printing, which is characterized in that: the precoating photosensitive plate is compounded and formed through an aluminum foil layer and a plastic layer which are jointed by an adhesive layer, an AL2O3 oxide layer is arranged on the surface of the aluminum foil layer, and a phototonus resin layer is coated on the AL2O3 oxide layer. The method comprises the following steps: 1. the aluminum foil plate can be executed anodic oxidation treatment according to the conventional surface electrochemistry way, light-sensitive resin liquid is coated to prepare the flake aluminium PS plate; and 2. the prepared flake aluminium PS plate and the plastic layer which is coated with adhesive are compounded. The precoating photosensitive plate has the advantages that the cost is low, the weight is light, the transportation is convenient, the preparing precision is high and the finished product rate is high; in addition, the physical chemistry performance is fine, the printing ink affinity performance is excellent after coating the light-sensitive resin liquid, so the planographic plate which has fine printing availability, good definition, perfect printing ink affinity performance and high printing resistance can be produced.

Description

technical field [0001] The invention relates to a method for manufacturing a precoated photosensitive plate for printing. Background technique [0002] In recent years, lithographic printing technology has been greatly developed in printing. The traditional method is to use metal aluminum plate as support for lithographic pre-coated photosensitive plate, which has played an important role in the development of lithographic printing technology. Metal aluminum plate has excellent Excellent mechanical properties, the surface of the aluminum plate has excellent physical and chemical properties after treatment, and it has excellent ink-friendly properties after coating the photosensitive resin solution, so it can produce good printing suitability, good clarity, good ink-friendly properties, and durability SCPG's lithographic printing plates. However, this kind of printing plate adopts an aluminum plate as a support body, which needs to consume a large amount of metal aluminum, a...
