Abstract
The invention relates to a method for UV (Ultra-Violet Ray) lustering of an offset press through hollowing lining papers, which has advantages of low production cost, high efficiency and improvement of service life of rubber blankets. The method specifically comprises the following steps of: choosing 3-6 pieces of lining papers, wherein the width of the lining papers is 750-800mm, the length is 1000-1100mm and the thickness of each piece of lining paper is 0.1-0.3mm; cutting the areas of the lining papers where corresponded to non-image parts of a print to form hollows, and reserving printing areas; according to the specification and the thickness of the papers of the print, calibrating the pressures among the ink rollers of all printing units, and then installing color sequence printing plate; flatly paving and correspondingly arranging the cut lining papers on the printing area of the rubber blanket, then installing the lining papers and the rubber blanket on a rubber roller, and then fixing and locking; choosing an anilox roller, starting a gloss oil after calibrating printing pressure, and then pumping UV gloss oil to a gloss oil chamber; adding ink to a printing color unit, then calibrating the pressures of the ink rollers and the printing pressure among the three rollers, and then starting the offset press.
Description
Technical field
The present invention relates to printing technology, especially a kind of method of carrying out offset press UV glazing by hollowing out interleaving paper.
Background technology
In China, a kind of mode of printing having empery status during offset printing, because print speed printing speed is fast, the multiple advantages such as printing quality is relatively stable, and the whole print cycle is short,
Offset printing is lithographic one, by means of rubber (rubberized fabric) picture and text on forme is delivered to the mode of printing on stock exactly.Blanket in press serves irreplaceable effect, as: it can well make up the out-of-flatness on stock surface, is that ink fully shifts, and he can reduce water on forme to transmission on stock etc.
When product produced by offset press, existing the line method that completely version UV glazing requires can have two kinds, and one adopts flexible resin plates to carry out glazing, and another kind adopts the method for segmentation blanket to carry out glazing.Adopt flexible resin plates glazing method, hollow out edge is relatively more neat, and printing quality is better, but when using flexible resin plates to print, due to paper knuckle or be accompanied with foreign material and make flexible resin plates be easy to damage, and then causes production cost higher; And adopt the method for segmentation blanket, segmentation blanket needs to expend the most of the time, operating efficiency is caused greatly to reduce, and the hollow out edge of the blanket of segmentation is neat not, printing quality is poor, blanket durability after segmentation is not strong, and as easy as rolling off a log damage, result also in the problem that production cost is higher.
Summary of the invention
The invention provides a kind of method of carrying out offset press UV glazing by hollowing out interleaving paper, technical problem to be solved is high, the inefficiency of production cost and the not strong problem of blanket durability in existing offset press UV method of lustering.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of method of carrying out offset press UV glazing by hollowing out interleaving paper, comprises the following steps:
Step 1: selecting 3-6 to open wide is 750-800mm, the long interleaving paper for 1000-1100mm, and the thickness often opening described interleaving paper is 0.1-0.3mm.
Step 2: the region of the non-image portion corresponded in printing by described interleaving paper cuts away, and forms hollow out, remaining printing zone.
Step 3: according to specification and the thickness of printing paper, between adjustment good each print couple, the pressure of ink roller, installs lustful sequence forme.
Step 4: by the corresponding printing zone be positioned on blanket of described interleaving paper tiling after cutting, more described interleaving paper to be installed on blanket cylinder and fixing and locking together with described blanket.
Step 5: select anilox roll, after the good squeegee pressure of adjustment, starts gloss oil pump and is extracted in gloss oil chamber by UV gloss oil.
Step 6: add ink to print couple, and after squeegee pressure between the good ink roller of adjustment, blanket cylinder and impression cylinder, start offset press and operate, realize line glazing.
The invention has the beneficial effects as follows: in prior art, the printing process of most of offset press is all directly cut blanket printing, and the difficulty of cutting blanket is larger than the difficulty of cutting mat paper, and consuming time, the blanket after cut is very short for service life, and the cost of blanket is higher; And in method of the present invention, interleaving paper is adopted to replace the printing zone part of blanket, blanket is made to avoid being cut, be specially: before offset press printing, first printing pattern copied on interleaving paper, as requested not needing the part of glazing to fall according to trace edge cuts, only leave the part needing glazing, want comparison blanket to cut to interleaving paper cutting much easier, and the hollow out edge of cutting is more neat, provides the printing quality of printing; When offset press prints, be contained on blanket cylinder by interleaving paper together with no longer needing the blanket split, the position of interleaving paper on blanket corresponds to the position of the glazing part originally needed when splitting blanket; Cost due to interleaving paper is lower and reusable, and structure is simple, fast easily manufactured, therefore not only reduces printing cost, also improves production efficiency; Because blanket no longer needs cut, durability greatly increases, and also further reduces production cost.
On the basis of technique scheme, the present invention can also do following improvement.
Further, in described step 1, selection 4 is wide is 787mm, the long described interleaving paper for 1092mm, and the thickness often opening described interleaving paper is 0.2mm.
The beneficial effect of above-mentioned further scheme is adopted to be the value range specifying squeegee pressure according to the thickness bonding apparatus of printing paper, selection can bear the interleaving paper close to this squeegee pressure scope, avoid causing dot gain because pressure is excessive, pressure is too small cause again trace apprehensive, print unreal, have a strong impact on the quality of printing; Plate cylinder and between blanket cylinder and impression cylinder by squeegee pressure effect under carry out indirect printing, under interleaving paper is padded on blanket, because blanket must control in the error range of 0.015mm to the required value of interleaving paper, error is crossed conference and is caused dot gain, error is too small, can cause the phenomenons such as low level site can not print, have a strong impact on product quality, then can select the interleaving paper of different size thickness according to the pressure between both printing thickness and blanket cylinder and impression cylinder.
Further, described interleaving paper adopts big gun base stock.
The beneficial effect of above-mentioned further scheme is adopted to be adopt the benefit of big gun base stock to be the characteristic that big gun base stock is rich: 1. compare with plain paper, its thickness is accurate, can not change along with the change of temperature and humidity; 2. flatness is high, can ensure squeegee pressure uniformity; 3. surface scribbles nonskid coating, ensures can not produce displacement in operation process repeatedly, and ghost phenomena causes a large amount of waste product to avoid product to occur; 4. the fibre density of paper is high, withstand voltage durable again, long service life, effectively improves the utilization rate of blanket, reduces production cost.
Detailed description of the invention
Be described principle of the present invention and feature below, example, only for explaining the present invention, is not intended to limit scope of the present invention.
