Abstract
The invention discloses an impression cylinder comprising a cylinder body, wherein the cylinder body is covered with a stainless steel metal plate; and the outer surface of the stainless steel metal plate is coated with an ink non-sticky ceramic coating. The impression cylinder has the characteristics that the cylinder body of the impression cylinder is covered with the stainless steel metal plate and the outer surface of the stainless steel metal plate is coated with the ink non-sticky ceramic coating, so that fresh ink which is not dried completely on paper can be prevented from staining the impression cylinder after reverse side printing.
Description
Technical field
The present invention relates to a kind of printing machine, particularly relate to a kind of impression cylinder that is used for printing machine.
Background technology
The two-sided printed matter that all need print of paper, usual way is twice printing, after one side is accomplished printing, paper is turned over a body, carries out the printing of another side then.Also having a kind of method is to use perfecting press, and paper once gets into machine, accomplishes double-edged printing; As shown in Figure 1, a colour cell of this perfecting press comprises two plate cylinders 1, two impression cylinders 2 up and down up and down; Coat blanket 3 on the impression cylinder 2; Picture and text printing ink on two plate cylinders 1 is up and down transferred on the blanket 3 of two impression cylinders 2 up and down separately, when paper 4 through up and down between two impression cylinders 2 time; Accomplish a double-edged color printing simultaneously; Usually chromatograp needs 2～4 colors, and then a perfecting press can comprise 2～4 identical colour cells, to accomplish the printing of tow sides 2～4 looks.
Such perfecting press because two impression cylinder 2 surfaces all coat blanket 3 up and down, paper is process between these two cylinders, be blanket and blanket to pressing, so be commonly called as " soft pressure is soft to roller ".Such machine is efficient, simplify, arrogate to oneself especially printed matters such as literal and chart owing to be " soft pressure is soft " form, congenital structures shape the sharpness of dots of its printed matter, reproducibility, all there is deficiency in Deformation of Paper property, and is prone to produce the flaw of printing ink ghost image.
Ad hocly want to set up the hard impression cylinder of a pair of surface texturisation; Impression cylinder is cooperated with blanket cylinder; And paper is between impression cylinder and blanket cylinder, to print; So just, it is clear to print, and overcomes defective in the past, is the current problem that solves of needing but how to design the hard and impression cylinder that oily dirt free is black of a surface texturisation.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art, and the impression cylinder that a kind of surface texturisation is hard and oily dirt free is black is provided.
Technical scheme of the present invention is achieved in that
A kind of impression cylinder comprises the cylinder body, on the cylinder body, is coated with the stainless steel metal plate, scribbles antiseized black ceramic coating at stainless steel metal plate outer surface.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
The present invention coats the stainless steel metal plate on the cylinder body of impression cylinder, and scribbles antiseized black ceramic coating on the stainless steel metal plate, thereby after can preventing back face printing, the fresh printing ink of the not bone dry on the paper is stained with dirty impression cylinder.
Description of drawings
Fig. 1 is the structural representation of a colour cell of printing machine in the prior art;
Fig. 2 is the structural representation of impression cylinder of the present invention.
The specific embodiment
The specific embodiment of the present invention is following:
Embodiment: a kind of impression cylinder, as shown in Figure 2, comprise cylinder body 1, on cylinder body 1, be coated with stainless steel metal plate 2, scribble antiseized black ceramic coating at stainless steel metal plate 2 outer surfaces.
Claims (1)
1. an impression cylinder is characterized in that: comprise the cylinder body, on the cylinder body, be coated with the stainless steel metal plate, scribble antiseized black ceramic coating at stainless steel metal plate outer surface.
