1. roll paper
Among the printing methods of web self-adhesive materials, at present, letterpress printing accounts for 97%, silk screen printing accounts for 1%, offset printing accounts for 1%, and flexo printing accounts for 1%.
Due to the use of web printing and processing, all processes are completed on one machine, so the production efficiency is high, the consumption is low, and the cost is low.
At present, the label printing machine in our country is in the form of letterpress printing, which has few functions and is only suitable for printing simple color blocks and labels with line patterns.
However, labels processed with web paper can be rewound into rolls, which can be applied to automatic labeling machines, barcode printers, electronic scales and other equipment, which is convenient for automated production.
Roll paper printing self-adhesive labels is the mainstream of self-adhesive printing in the world. (sticker)
2. Sheet of paper
Among the printing methods of such self-adhesive materials, offset printing accounts for 95%, letterpress printing accounts for 2%, silk screen printing accounts for 2%, and computer and printing account for 1%.
The self-adhesive label printing on a single sheet of paper is the same as the ordinary printed matter. Each process is completed on a single machine, with low production efficiency, high consumption and high cost, but the printing quality is good.
If the offset printing process is used, the quality of labels printed in four colors is much better than that of similar products printed by label printing machines.
However, since the finished self-adhesive printed on a single sheet of paper is in the form of a single sheet of paper and cannot be rewound, such products can only be manually labelled and cannot be automatically labelled on an automatic labeling machine.
Sheetfed printing is suitable for large-area self-adhesive color prints. Such as posters, posters, large-scale labels, etc., not limited to label products. It can be said that sheet-fed self-adhesive printing is an important part of the self-adhesive printing industry. (Adhesive stickers)
