, Expand device functions. Some simple label equipment has few functions, such as hot stamping, die cutting, punching and printing using a set of channels. In order to meet the various processing needs of labels, the web needs to be processed twice or multiple times at the same station. Complete printing of the entire label.

2. Ensure quality and reduce costs. Multi-functional self-adhesive label equipment often uses secondary processing of labels in order to ensure quality and reduce consumption. Because the rotary machine has many functions, any problem in any process will cause the labels to be scrapped during the printing process. Therefore, in order to ensure the printing quality of the labels, some printing factories choose to process the labels by printing first and then processing, and loading the roll paper on the machine twice. (Can be on your own machine or on two devices). Although production efficiency dropped, overall consumption dropped. Quality is guaranteed and costs are reduced.

4. Increase the number of printing colors. Intermittent rotary machines (flat flattening, round flattening), limited by the structure of the rubber roller, can print up to four colors. If more than five colors need to be printed on the label, it must be printed twice: that is, four colors can be printed at one time. Then, use the machine again to print other colors.

5. Increase the printing area. The paper feeding width of the intermittent rotary machine is fixed. To increase the printing area of ??the label, it is necessary to use a large-area rubber roller (usually the machine is equipped with four-color, three-color, and two-color rubber rollers). The inking area of ??the rubber roller increases and the number of colors on the rubber roller decreases. Therefore, to ensure large-area label printing, it is necessary to print twice or multiple times.

Rotary printers have very high requirements for the printing production environment. The power must be stable, the temperature and humidity must be moderate, the ventilation must be good, and the operation must be standard, so this requires operators to have a strong sense of responsibility and be strict. Follow the operating procedures, develop good working habits in daily work, pay attention to the operation and maintenance status of the rotary printer, check if there are any problems with the machine, ensure that the machine is in good technical condition, and make full preparations to make the rotary printer functions can be fully utilized.

The ink balance of the trademark printer's printing. During the printing process, even if the water delivery equipment is adjusted and operated accurately, it will be affected by shutdowns, changes in temperature and humidity in the printing workshop, machine operating speed, ink, paper types, and blank areas of the layout as the number of prints increases. Restrictions such as weakened water function will also directly affect the ink balance. Therefore, the balance of ink and wash must be controlled by experienced technicians.
