Description
Technical field
The invention belongs to printing technology fields, and in particular to a kind of back side mistake of the soft trade mark of intaglio printing press polychrome group chromatography
Water installations and technique.
Background technology
Current intaglio printing press mostly be use the mutual chromatography of polychrome group, recto printing technique carry out, from paper feed to
Polychrome printing finishes, and paper will pass through the processes such as multiple inking, baking, cooling.In ＜ 150g/m2In paper products printing, paper
Opening can be because ambient temperature and humidity variation and the influence of the factors such as each colour cell drying of printed on line, cooling make paper dehydration or moisture
It is uneven and phenomena such as lead to paper distortion, bending, seriously affect the quality of product, deformed sheet will have a direct impact on rear process and add again
Precision, quality and the working efficiency of work, more seriously influence product qualification rate, lead to product rejection.It is asked to solve this
Topic needs to infiltrate special moisturizing back coating liquid to back side of paper progress moisturizing damping by special printing plate before printing, then dries again
It is dry, so that paper is shaped before print, balancing paper for follow-up each colour cell chromatography stretches, and reduces chromatography error, and it is flat to improve printing product
Whole degree is laid a solid foundation.But existing intaglio printing press does not have the back side to cross water installations, need install additional or using original printing element into
Row transformation, originally printing element cannot overturn paper, therefore cannot carry out the back of the body and apply conditioning；Secondly original printing plate cylinder due to
Electric carving version depth crosses water paper page depth mismatch with the back side, can not be used for doing water roller；Moisturizing back coating liquid is matched again
The ratio of system is improper, and to also result in printing effect undesirable.Therefore, it is necessary to develop one kind to be overturn to paper printing face,
Electric carving version depth is crossed water paper page depth with the back side and is matched, the ratio intaglio printing press polychrome group set appropriate that moisturizing back coating liquid is prepared
Water installations and technique are crossed in the back side for printing soft trade mark, the problem of to eliminate paper distortion, improve printing product flatness, improve soft quotient
Chromatography effect is marked, to improve the qualification rate of product and the satisfaction of user.
Invention content
The purpose of the present invention is to provide one kind to be overturn to paper printing face, and electric carving version depth crosses water with the back side
Paper page depth matches, and water dress is crossed at the back side for the soft trade mark of ratio intaglio printing press polychrome group chromatography appropriate that moisturizing back coating liquid is prepared
It sets and technique, the problem of to eliminate paper distortion, improves printing product flatness, improve soft trade mark chromatography effect, to improve
The qualification rate of product and the satisfaction of user.
To achieve the above object, the technical solution adopted by the present invention is：
Water installations and technique are crossed in a kind of back side of the soft trade mark of intaglio printing press polychrome group chromatography, wherein：Water installations setting is crossed at the back side
Between the unwinding device being sequentially arranged along production line and the first colour cell gravure unit of polychrome group chromatography, water installations packet is crossed at the back side
Including rack, slewing rollers, crosses water roller, pressure roller, the second feed rollers and drying box at sink, and sink is arranged in rack, and sink is built-in
There is the moisturizing back coating liquid that water mixes in proportion with ethyl alcohol, crosses water roller and be mounted in sink across sink two side, pressure roller and mistake
Water roller excircle is tangent and is mounted on the top of water roller, and drying box is equipped with above rack, is arranged inside drying box
There are internal guide roller group, the quadrangle outside drying box to be provided with external orientation roller group, paper is from unwinding device, face-up
By the first feed rollers, changes paper printing face by slewing rollers and contact at the back side of paper with water roller is crossed, then by the second paper feeding
Roller and internal guide roller group are directed into drying box, finally flow surface are overturn again by external orientation roller group, by the front of paper
Enter in the first colour cell gravure unit through third feed rollers upward, makes the galley in the front and the first colour cell gravure unit of paper
Roller contact carries out presswork.
Further, it is electric carving gravure to cross water roller, and width is consistent with paper breadth, and electric carving version depth is 15-20 μm.
Further, drying box is thermostatic hot-air drying box.
Water installations and technique are crossed in a kind of back side of the soft trade mark of intaglio printing press polychrome group chromatography, and technique includes the following steps：
(1) moisturizing back coating liquid is prepared, it is different depending on the humidity of working environment, water and ethyl alcohol are pressed 1:0.2~4 ratio mixing
It stirs evenly；
(2) prepared moisturizing back coating liquid is added in screw clamp, liquid is made not cross at water roller circumference 1/5~1/4；
(3) back side of paper is contacted with water roller excessively downward, moisture supplement is carried out to back side of paper, then by the second feed rollers
It is directed into drying box with internal guide roller group, control drying temperature is 52 DEG C~58 DEG C；It is 115~125 to control print speed printing speed
M/min；
(4) paper after drying overturns flow surface by external orientation roller group again, by the face-up through third paper feeding of paper
Roller, which enters in the first colour cell gravure unit, to be printed.
Further, when working environment humidity is less than 20%, water and ethyl alcohol press 1 in moisturizing back coating liquid:0.2~0.25
Ratio mixes.
Further, when working environment humidity is less than 20%~30%, water and ethyl alcohol press 1 in moisturizing back coating liquid:0.5~
0.7 ratio mixing.
Further, when working environment humidity is 30~40%, water and ethyl alcohol press 1 in moisturizing back coating liquid:1 ratio is mixed
It closes.
Further, when working environment humidity is 40%~60%, water and ethyl alcohol press 1 in moisturizing back coating liquid:1.5 ratio
Example mixing.
Further, when working environment humidity is more than 60%, water and ethyl alcohol press 1 in moisturizing back coating liquid:4 ratio is mixed
It closes.
The beneficial effects of the invention are as follows：
1, paper printing face is overturn by slewing rollers, back side of paper is made to contact progress back side benefit with water roller is crossed
Water, it is dry after again by external orientation roller group to flow surface carry out overturning make recto contact with the printing plate cylinder of printing element into
Row printing, solves the problems, such as that existing equipment paper printing face cannot be overturn, and successfully having carried out the back of the body to paper applies conditioning；
2, the matched water roller excessively of water paper page depth is crossed using electric carving version depth and the back side, so that back side of paper is crossed water equal
Even consistent, depth is moderate, ensure that the flatness of printed matter；
3, fixed effect before paper print is made using the moisturizing back coating liquid of different proportion according to the variation of operating ambient temperature
It is good, it balances paper for follow-up each colour cell chromatography and stretches, reduce each colour cell chromatography error, improve printing product flatness and accomplish fluently base
Plinth.
