Problems solved by technology

①. Flexographic printing has not been promoted for a long time, and it is not as mature as offset printing and gravure printing in technology
It is manifested in the difficulty of plate making and high cost; there is still a gap between the printing dot definition and PS plate offset printing
②. Each trademark printing with different specifications needs to be equipped with high-precision rollers with different circumferences, which increases the printing cost
③. The stability of printing is not high, and it is easy to produce batch color difference
④, the quality inspection of printing is difficult, and it is not easy to exclude defective products
⑤ It needs to be printed with high-grade imported materials, which increases the cost
⑥ The equipment is expensive and difficult to maintain
[0003] 2. Reel gravure printing: printing with computer metal engraving plate, the cost is too high; it is mainly aimed at printing on plastic film, and the printing effect on coated self-adhesive materials is not ideal
[0004] 3. Reel form machine printing: PS plate is used for printing, but the size of PS plate is fixed, and the distance between trademarks cannot be guaranteed to be equal. Flexographic printing can be installed, but multiple sets of high-precision rollers of different specifications need to be configured, and the cost is too high
[0005] 4. Roll offset printing: Due to the fixed size of the PS plate, the equal spacing between trademarks cannot be guaranteed
[0006] 5. Ordinary sheet-fed offset printing PS plate printing: it has a solid and extensive technical foundation, fast printing speed, large printing area, printing with PS plate, low printing cost and high precision, but it cannot be printed on rolls

Embodiment Construction

[0041] The present invention will be further described below in conjunction with embodiment. The production process of this kind of sheet-fed offset printing reel color printing self-adhesive trademark mainly includes the following steps: surface paper sheet PS plate printing → edge trimming → sheet-fed printing surface paper is automatically glued into a roll → self-adhesive precision coating compound → Roll Die Slitting

[0042] 1. PS plate printing on surface paper sheet: ① Typesetting: according to the direction of automatic labeling of the roll, the trademarks are arranged equidistantly parallel to the bite edge, and the die-cutting tracking point and tracking line are marked on the edge of the bite edge and both sides of the drag gauge , Mark the trimming line on both sides of the pull gauge and side gauge. ②. The surface paper is treated with static electricity, temperature and humidity before printing to reduce the expansion and contraction of the paper. ③. When prin...

Abstract

The production process of plane sheet offset rolled colour-printed pressure-sensitive adhesive label includes the following steps: 1. face paper plane sheet PS plate printing; 2. edging; 3. automatically-adhering single-sheet printed face paper and coiling; 4. finely-coating pressure-sensitive adhesive and lamination; 5. cutting roll and die-cutting. The single-sheet printed face paper automatically adhering and coiling process includes the following steps: positioning face paper to the glue-applying place, at the same time transferring and pressing pressure-sensitive adhesive onto the face paper form parting paper; adhering head and tail of face paper, digital-control taking up by servo-motor, rectifying deviation, using position sensor and tension control system to regulate and control brake and constant tension rolling up.

Description

technical field [0001] The technical fields of offset printing, flexo printing, rotary trademark printing, self-adhesive coating compounding and post-processing, etc., are mainly a production process of sheet-fed offset printing roll color printing self-adhesive trademarks. Background technique [0002] 1. Flexographic full-rotary trademark printing: represents the highest level of roll-to-roll color printing self-adhesive trademark printing technology. It is comparable to offset printing, but it still has many unavoidable shortcomings. ①. Flexographic printing has not been popularized for a long time, and it is not as mature as offset printing and gravure printing in technology. It is manifested in the difficulty of plate making and high cost; there is still a gap between the printing dot definition and PS plate offset printing. ②. For each type of trademark printing with different specifications, high-precision rollers with different circumferen...
