Processing Method Of Paper Self-adhesive Label

1. Web paper

Among the printing methods of web paper self-adhesive materials, at present, embossing 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 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, China's label printing machine is in the form of letterpress printing with few functions. It is only suitable for printing labels with simple color blocks and line patterns. The printing quality is not as good as that of sheet fed offset printing. However, labels processed with web paper can be rewound into rolls, which can be applied to automatic labeling machines, bar code printers, electronic scales and other equipment, which is convenient for automatic production. Web printed self-adhesive label is the mainstream of self-adhesive printing in the world. (self adhesive sticker)

2. Sheet fed

Among the printing methods of this kind of self-adhesive materials, offset printing accounts for 95%, embossing printing accounts for 2%, silk screen printing accounts for 2%, and computer and printing account for 1%. The self-adhesive label printing of single sheet paper is the same as that of ordinary printed matter. Each process is completed on a single machine, which has the advantages of low production efficiency, high consumption and high cost, but the printing quality is good. If the offset printing process is adopted, the label quality of four-color color printing is much better than that of similar products printed by label printing machine. However, since the finished self-adhesive printed on sheet fed paper is in the form of sheet fed paper and cannot be rewound, such products can only be labeled manually and cannot be labeled automatically on the automatic labeling machine. Sheet fed printing is suitable for large-area self-adhesive color printing. Such as posters, posters, large-area labels, etc., are not limited to label products. It can be said that sheet fed self-adhesive printing is an important part of self-adhesive printing industry
