Paper Label Processing Features

Sheets

In the printing method of such adhesive materials, offset printing accounted for 95%, embossing printing accounted for 2%, screen printing accounted for 2%, and computer and printing accounted for 1%. The self-adhesive label printing of sheet-fed paper is the same as that of ordinary prints, and each process is completed on a single machine. The production efficiency is low, and the cost is high, but the printing quality is good. If the offset printing process is adopted, the quality of the labels printed by the four colors is much better than that of similar products printed by the label printers. However, since the form of the self-adhesive sheet-fed printing product is a sheet of paper and cannot be rewound, such products are only hand-labeled and cannot be automatically labelled on an automatic labeling machine. Sheet-fed printing is suitable for large-area self-adhesive color prints. Such as posters, posters, large-area labels, etc., are not limited to label products. It can be said that self-adhesive sheet-fed printing is an important part of the adhesive printing industry.

web

In the printing method of web-type self-adhesive materials, currently, 97% of the printing area, 1% of screen printing, 1% of offset printing, and 1% of flexographic printing. Due to the use of web printing, all processes are completed on one machine, resulting in high production efficiency, low consumption, and low cost. At present, China's label printing presses are in the form of letterpress printing, with few functions. They are only suitable for printing simple color blocks, and labels with line patterns are not as good as those for sheetfed offset printing in terms of printing quality. However, the label processed by the web can be re-wound into a roll, which can be applied to automatic labeling machines, bar code printers, electronic scales and the like, and can be easily automated. Web printing stickers are currently the mainstream of adhesive printing in the world.
