According to the processing method of self-adhesive labels, the gilding method is divided into sheet metal stamping and roll paper stamping. Sheet fed bronzing is the same as traditional bronzing process, and is processed on special bronzing machine. Roll foil stamping is finished on label linkage machine. It is the most widely used processing method. Now, Ji'nan dry glue introduces you to roll up data bronzing with the following methods:
1. Flat stamping on the label machine.
Gravure label printing machine is flat or circular press flat equipment, because the roll paper intermittent feeding, so all use flat stamping method. In general, the bronzing workstation is a separate unit, and some models share a single unit to separate the use of bronzing to die cutting.
2. Multi position flat stamping.
Some models have two-station bronzing units, one of which is close to the plate, the end of horizontal bronzing, the other is a separate unit, the end of vertical bronzing. The model can carry out double color bronzing together.
3. Flat press and hot stamping on the machine.
The processing machine is specially designed for processing the reel label after printing and the label that does not need printing. Hot stamping is one of the functions of the machine. Hot stamping equipment is widely used in the machine. Its working principle is the same as the above-mentioned labeling machine.
4. Rotary press stamping.
The stamping plate used for round stamping is in the shape of a cylinder. When stamping, the stamping cylinder and the stamping cylinder touch each other to finish stamping. Round stamping is suitable for the use of continuous paper feeding wheel labeling machine, but there are certain requirements for the speed of paper feeding, that is to say, the printing speed has an impact. However, compared with flat stamping, the power is greatly increased. The round pressure stamping roller has relatively high manufacturing cost, so it is only suitable for long version of live stamping.
5. Hot stamping on rotary machine.
This is a new process of bronzing, no longer the use of heated metal plate, but the use of printing adhesive method, so that the metal foil transport, complete bronzing. The technological process is as follows: the UV pressure-sensitive adhesive is printed on the position where the printing needs to be stamped, and the adhesive is dried by the UV drying equipment, then the special metal foil is combined with the pressure-sensitive adhesive, and then the metal foil is stripped off, so the transfer part of the metal foil is transferred to the surface of the printed matter, and the cold stamping is completed. Cold stamping is a new process with a bright future because of its low cost, energy saving, high output power, and the ability to use existing equipment and components without additional equipment.
