Process prepress print labels note
In pre-press processing, many customers orders are designed to offset or gravure-based approach, this manuscript if the use of flexible printing, proofs will be a lot of quality problems, such as color is not in place, the level was not obvious , such as a hard edge. Therefore, to solve such problems, communicate with customers in a timely manner is essential.
Print Network HC In recent years, Label Increasingly competitive market, users label printing quality is ever increasing, at the same time, narrow flexible printing technology used, not only to expand the company's business scope and production capacity, and in the pre-press processing, Plate Select, screen version of the production and flexible printing technology has also accumulated rich experience.
First, pre-press processing, many customers Design Orders are based on Offset printing Or gravure methods based, this manuscript if the use of flexible printing, proofs will be a lot of quality problems, such as color is not in place, the level was not obvious, such as a hard edge. Therefore, to solve such problems, communicate with customers in a timely manner is essential.
Secondly, the choice of flexo plates must shop around on. Companies need more than the printing plate with the company Cooperation , The use of the plates, cable version of the production level of the transition, the increase of network compensation, plate stretching rate of full understanding. This is not only conducive to the production, but also good quality parameters can be controlled to avoid human interference, reducing the generation of fault.
Again, due to the special label printing, flexo narrow Printing Equipment Compared with letterpress and other types of flexible printing equipment in terms of a prominent feature, narrow flexible printing equipment is not only simple, print quality and operational efficiency, portfolio and strong, can do a wider range of products, more competitiveness.
1. The choice of color sequence
Flexible label printing with its graphic part of the main field, lines, text-based, mostly used in printing materials, paper, aluminum foil, Plastic Films, stickers and other. Water-soluble or solvent based printing ink absorbent material, after the role of infrared hot air drying, materials pumping up phenomenon occurs, affecting the accuracy overprint. With large color version should be on the field after the unit by printing, as substrates, after absorbing a large number of ink through the infrared drying, change the field unit than other units pumping up big. If the field must be part of the group on the front of the color printing can be a conscious direction of the upper and lower slightly bigger compensation to cover printing material losses caused by pumping up.
2. Platemaking Note (1) trapping Flexibility in the production version, a certain amount of trapping is conducive to printing registration. Trapping is too small or without trapping processing, will result in bad printing appearing register (tainted white); trapping the edge of printed products through the General Assembly in the emergence of a large profile, affecting the overall effect of labels.
(2) layout design As the basic use of web flexo printing, seamless sleeve technology, significant savings in paper, but some Flexo machine And can not be achieved on-line die-cutting, but also follow-up processing (cutting, etc.), so in full consideration of the layout design process for the follow-up to leave a sufficient margin.
(3) the choice of raw and auxiliary materials
Choice should not be limited to its unit price, quality should be printed as the first element of the product cost analysis, the general need to consider the raw and auxiliary materials, mainly paper and ink.
I am an expert from Cheap On Sales, usually analyzes all kind of industries situation, such as industrial floor scrubbers , grating machine.
