The self-adhesive label printing process is as follows: unwinding: intermittent: there is no tension change when the roll paper is unwinding, so no adjustment is required. Used in flat and round flat labeling machines, the unwinding speed is slow. Because this type of equipment has no paper positioning and correction device, the end of the roll paper is required to be clean and tidy to ensure accurate overprinting during printing.
Continuous type: used in the round-to-round labeling machine. Because the paper has tension changes when the diameter and speed of the roll paper changes, this device has an automatic or manual tension control mechanism, as well as a roll paper correction device to ensure smooth paper feeding and print quality.
Hot stamping: Flat flattening: used in circular flattening and flat flattening labeling machines, with low speed.
Round pressing: applied to round pressing round label printing machine, fast speed, continuous hot stamping, generally seldom used, generally use gold printing process instead of hot stamping.
Printing: Flat pressing: Suitable for small areas, simple pattern printing, such as price labels, bar codes, etc.
Round flattening: suitable for label printing with solid and general patterns, and can be used for simple color screen printing. Round press round is suitable for all kinds of pattern label printing, especially suitable for high-end color mesh label printing.
UV printing: In the above three printing methods, after UV drying, film adhesive materials can be printed.
