The technical scheme adopted by the invention is as follows:
the local UV polishing method comprises a plate cylinder and an impression cylinder, wherein the plate cylinder and the impression cylinder are both rotatably arranged, and a gap exists between the plate cylinder and the impression cylinder; the hardness of the resin plate is 73HB-76HB;
and conveying the paper between a plate cylinder and an impression cylinder, transferring the UV varnish on the resin plate onto the paper by rotating the plate cylinder, and curing the UV varnish on the paper by UV to form a pattern.
It should be noted that, the present UV polishing method is based on the improvement of the present UV polishing machine, for the conventional UV polishing machine, only a PS plate capable of winding is required to be disposed on the plate cylinder, a resin plate is disposed on the PS plate, when the plate cylinder rotates, the anilox roller above the plate cylinder is only in contact with the resin plate, the anilox roller transfers the UV varnish of itself onto the resin plate, one side of the anilox roller is provided with a varnish groove, the varnish groove continuously transfers the UV varnish stored by itself onto the anilox roller, the resin plate transfers the UV varnish of itself onto the paper when contacting the paper, and since the PS plate is not in contact with the paper, only a UV varnish spot (namely, the partial polishing) with the same shape as the resin plate is left on the paper after the plate cylinder rotates, the UV varnish spot is cured after UV irradiation, thereby forming a cured pattern on the paper, and other places of the paper are not stained with UV varnish, and the cured pattern is not formed.
In the UV polishing method, the hardness of the resin plate is 73HB-76HB, so that the hardness value is moderate, and the resin plate cannot be obviously deformed.
In the UV polishing method, resin plates with different shapes are arranged on the PS plate, so that UV gloss oil spots with different shapes can be formed on paper.
In summary, according to the scheme, the PS plate and the resin plate are arranged on the basis of the traditional UV photochemical machine, so that the local polishing of paper is realized.
Optionally, the PS plate is an aluminum PS plate, and the resin plate is a resin plate made of photosensitive resin.
The PS plate is made of aluminum and has a relatively thin thickness so that the PS plate wound on the plate cylinder can be replaced as needed.
Alternatively, the shrinkage of the resin plate is 99.3%.
Optionally, the thickness of the resin plate is 1.1 mm-1.2 mm.
The beneficial effects of the invention are as follows: the PS plate and the resin plate are arranged on the basis of the traditional UV photochemical machine, so that the local polishing of paper is realized.
Description of the drawings:
FIG. 1 is a schematic diagram of the principle of a localized UV glossing method;
FIG. 2 is a schematic view of the positions of a resin plate, a PS plate and a plate cylinder;
fig. 3 is a schematic structural view of a resin plate.
The reference numerals in the drawings are as follows: 1. a plate cylinder; 2. PS version; 3. a resin plate; 4. paper sheets; 5. an impression cylinder; 6. an anilox roller; 7. and a gloss oil groove.
The specific embodiment is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a local UV polishing method comprises a plate cylinder 1 and an impression cylinder 5, wherein the plate cylinder 1 and the impression cylinder 5 are rotatably arranged, and a gap exists between the plate cylinder 1 and the impression cylinder 5, and the local UV polishing method is characterized by also comprising a PS plate 2 and a resin plate 3, wherein the resin plate 3 is arranged on the PS plate 2, the PS plate 2 is wound on the plate cylinder 1, the PS plate 2 does not contain UV varnish, and the resin plate 3 is used for absorbing the UV varnish; the hardness of the resin plate 3 is 73HB-76HB;
the paper 4 is fed between the plate cylinder 1 and the impression cylinder 5, and the plate cylinder 1 rotates to transfer the UV varnish on the resin plate onto the paper 4, and the UV varnish on the paper 4 is subjected to UV curing to form a pattern.
It should be noted that, the present UV polishing method is based on the improvement of the present UV polishing machine, for the conventional UV polishing machine, only a PS plate 2 capable of winding is required to be arranged on the plate cylinder 1, the PS plate 2 is provided with a resin plate 3, when the plate cylinder 1 rotates, the anilox roller 6 located above the plate cylinder 1 is only in contact with the resin plate 3, the anilox roller 6 transfers the UV gloss oil of itself to the resin plate 3, one side of the anilox roller 6 is provided with a gloss oil groove 7, the gloss oil groove 7 continuously transfers the gloss oil stored by itself to the anilox roller 6, when the resin plate 3 is in contact with the paper 4, the UV gloss oil on itself is transferred to the paper 4, and as the PS plate 2 is not in contact with the paper 4, only the resin plate 3 is in contact with the paper 4, so that after the plate cylinder 1 rotates, only a UV gloss oil spot (namely, the partial polishing is realized) with the shape of the same as that of the resin plate 3 is left on the paper 4, the UV gloss oil is cured after UV irradiation, thus the paper 4 is cured, and no other UV gloss oil is formed on the paper 4.
In the UV polishing method, the hardness of the resin plate 3 is 73HB-76HB, and the hardness value is moderate, so that the resin plate 3 does not deform obviously.
In the UV polishing method, the resin plates 3 with different shapes are arranged on the PS plate 2, so that UV gloss oil spots with different shapes can be formed on the paper 4.
