Abstract
The utility model provides a composite plate material for lithographic printing, comprising an aluminum layer and a plastic sheet base and being formed by the way that the aluminum layer and the plastic sheet base are glued together by an adhesive agent. The aluminum layer surface is composed of a surface coarsening layer, an oxide film layer and a photosensitive paste layer. The utility model has the advantages of aluminum material saving, ensured printing quality and decreased printing cost.
Description
The utility model relates to a kind of printing material, and specifically, it is a kind of lithographic printing composite.
As everyone knows, the plate that present lithographic printing is used generally adopts the metal mold plate, promptly full aluminium stencilling material.For intensity and the press resistance rate that guarantees plate, require the suitable thickness of plate; In order to guarantee printing quality, require plate flatness height simultaneously.Therefore, full aluminium stencilling material generally will consume a large amount of aluminium, and general rolls the requirement that the aluminium machine is difficult to satisfy its flatness.
So the utility model provides the compound plate of the novelty of aluminium lamination that a kind of lithographic printing uses and plastic base, its only needs to consume the aluminium of the full aluminium stencilling of 1/6-1/10 material, and the intensity of plate, press resistance rate and printing quality can reach the index of full aluminium type fully.
The purpose of this utility model reaches in the following manner:
A kind of composite plate material for lithographic printing comprises aluminium lamination, aluminium lamination surface coarsening layer and oxidation film layer and the photosensitive layer that applies above thereof, it is characterized in that described aluminium lamination is the composite layer of aluminum that aluminium lamination and plastic base form by the adhesive layer with adhesive.
It is characterized in that described aluminum layer thickness is that 30-100 micron and described plastic base thickness are the 100-500 micron.
It is characterized in that described plastic base is terylene, polyethylene, polypropylene foil base.
The adhesive layer that it is characterized in that described adhesive is the adhesive layer that polyurethane binder forms.
Advantage of the present utility model is tangible, and it and full aluminium stencilling material contrast have following advantage:
At first, the required aluminium of the utility model only is the 1/6-1/10 of full aluminium stencilling material consumption; Secondly, the flatness of aluminium of the present utility model, general milling train can reach; The 3rd, press resistance rate of the present utility model and printing quality can reach the index of full aluminium stencilling material fully; The 4th, cost is low, and processing is simple.
Below, the utility model will be done the detailed description in a step by drawings and Examples:
Accompanying drawing 1 is the generalized section of the compound plate of the utility model.
As shown in Figure 1, the compound plate of the utility model is mainly by 30 to 100 microns, be preferably the aluminium lamination ［ 3 ］ of 50 micron thickness and by 100 to 500 microns, be preferably the dacron chip base of 200 micron thickness, polyethylene or polypropylene foil base ［ 5 ］ form composite layer of aluminum by the adhesive layer ［ 4 ］ with polyurethane binder, described composite layer of aluminum is by degreasing, ac electrolytic roughening surface and alternating current electrolysis oxidation form surface film oxide ［ 2 ］, last on the roughened layer of composite layer of aluminum and oxidation film layer, apply photosensitive layer ［ 1 ］ again, thereby obtain the utility model composite plate material for lithographic printing.
Above-mentioned compound plate is made a plate according to operational procedure, and open or Hai Debao-4 opens on the offset press and uses by Hai Debao (GTO)-8, press resistance rate is 53000 seals, and can reach the printing quality of full aluminium stencilling material.
Claims (5)
1, a kind of composite plate material for lithographic printing comprises aluminium lamination, aluminium lamination surface coarsening layer and oxidation film layer and the photosensitive layer that applies above thereof, it is characterized in that also comprising the plastic base that forms composite layer of aluminum by adhesive and aluminium lamination.
2, compound plate as claimed in claim 1 it is characterized in that described aluminum layer thickness is 30 to 100 microns, and described plastic base thickness is 100 to 500 microns.
