Zhengzhou reel label printing technology centers - provide roll label printing technology, to undertake UV printing, PVC printing, label printing, wine label printing, variable data printing, barcode printing and other services

Label printing paper types can be divided into leaflets and the web in two ways, click into the Chinese version:

(1) self-adhesive label paper sheet printing: This paper self-adhesive materials, printing methods, offset printing 95%, 2% letterpress printing, screen printing accounts for 2%, variable data printing and spray Printing ink 1%. Label printing sheet of stickers printed with the same general, the process to complete a single printing press, low productivity, high cost of print production, quality control manual, but the print quality. If the use of offset printing press printing process, after four-color printing color quality than the sticker roll label printing press similar to the effect of self-adhesive material is better. However, self-adhesive sheet-fed printing leaflets in the form of the finished product is not rewinding, Label leaflet hand-labeling the product label only, not in the automatic labeling machine automatic labeling. For large sheetfed color printing self-adhesive, such as posters, posters, large area printed stickers, self-adhesive labels are not limited to the size and color. It can be said sheet-fed printing stickers sticker printing industry is an important part of this self-adhesive paper printing machine single major Heidelberg, Roland, Komori Japanese brands such as presses more.
(2) self-adhesive paper roll UV printing is generally the form of printing, web printing forms, self-adhesive paper labels in roll form printed materials, mainly letterpress 90%, 1% printing, offset printing 8%, 1% flexo. As a result of self-adhesive label paper roll printing process, all processes can also be a complete one-stop printing machinery, and can be rewinding, cutting, stamping can be produced, their production efficiency, low consumption of die, Printing costs are low. At present, China's label printing is letterpress printed form, the function of small, only suitable for printing simple blocks of color, line type pattern of self-adhesive labels, sheet-fed printing quality as offset printing out stickers. However, die-cutting process using the web can be rewinding label rolls, can be used in automatic labeling machines, barcode printers, electronic scales and other equipment used on continuous printing, suitable for automated production. Web printing stickers is currently the world's mainstream label printing. Web sticker printing and general printing to paper methods, it is axial tabs move to achieve overlay. On the plate cylinder is fitted with three overlay version of the same, when the self-adhesive paper in embossed platform shift once every jump, the plate cylinder reciprocating rotation along a horizontal direction, to achieve a color printing. Three-color overlay label printing, sticker paper on the platform must be moved three times to complete the full-page overlay work. The advantage of this printing structure, to simplify the construction of the equipment, reduce the size of the machine. However, due to the printing stroke is shorter, print is not easy to dry and not conducive to the completion of a large area of ??wet-wet trapping, and more suitable for small-area trapping or overprint. Structure from the imprint of view, rotary printing machine of quality self-adhesive flat platen-type machine than good, especially in the printing field layout, the ink can be achieved uniformly thick but good results. The structure of the self-adhesive platen machine, printing a large area on the ground version of the easy layout (self-adhesive printed) appears oil slick-like ink, print quality is not good, the layout is only suitable for small label printing, post-roll printing The label can be done by Rotary.
