What are the precautions in the process of paper bag printing?

Paper bag printing is a major development direction in the printing industry. Although the process of making handbags is relatively simple, there are still many details that need to be paid attention to.

1、 In the process of handbag printing, pay attention to the use of the same ink and do not mix different inks. If the two cannot be dissolved, the quality of handbag will be affected.

2、 When printing, the nature of the ink should be, the direct sunlight should be avoided, and the indoor temperature should be maintained, preferably within 10-26 degrees Celsius.

3、 In the process of handbag printing, if the ink is not stirred regularly, it is easy to bond, which will affect the overall presentation of the handbag. However, be careful not to dilute too much, so the printed products will have color difference, which can be adjusted by adding thickener appropriately.

4、 In the printing process, we should also give full play to the role of water. It can not only control the ink viscosity, but also balance the pH value. If the pH value is not controlled between 8.5-9.5, water or pH stabilizer should be added for adjustment.

5、 Handbag is a kind of high-speed printing. The printing process is fast, so there are also requirements for the dryness of the ink. If the drying speed of the ink is too slow, desiccant can be added appropriately to its drying speed. If the printing is carried out before the ink is dry, the layout will be wasted, sticky and dirty, This will also affect the overall printing efficiency.

6、 After printing, the equipment should be cleaned. Only when the ink on the equipment is still viscous can the cleaning speed be improved. If it cannot be cleaned with clean water, some cleaning agents can be added appropriately.
