printing paper products have been widely used in our daily life. Every day when we go out, we will carry some items in a handbag, because printing paper products are easy to use, not afraid of losing, very suitable for temporary use or application in unexpected scenarios. For consumers, the most basic function of a handbag is to be durable. However, for merchants or printers, handbag printing will encounter various problems. Today Xiaobian will tell you how to solve these problems when we encounter them!

1. Since the ink is a pure water system, it is not allowed to mix the ink with alcohol ink and solvent ink or add organic solvents to the ink to avoid printing quality problems.

2, ink should be in the room, the room temperature is 5℃ -50 ℃ Celsius.

3, when using, use the mixing rod to stir the ink in the barrel, measure its viscosity and pour it into the ink tank. If the viscosity is too high or too low, thinner or thickener can be added for conditioning.

4. In the printing process, due to the evaporation of water, the viscosity of the ink will increase the PH value, the PH value should be controlled between 8.5 and 9.5, if beyond this range, the PH conditioning stabilizer can be used to maintain the stability of the viscosity and viscosity PH value.

5. In general, ink is very suitable for printing paper products and high-speed printing. If the low-speed printing is too fast or the printing effect is poor, a certain proportion of slow drying agent can be increased.

6. After printing, the remaining ink should be collected back into the corresponding original bucket, or the ink tank should be covered tightly for next use. Be careful the conjunctiva on the surface of the ink is caused by water evaporation. Thicken and even dry out.

7. The ink left on the printing setting after printing paper products can be cleaned with water before it is completely dry, and the ink that cannot be cleaned with water can be cleaned with a cleaning agent.

8. The suitability of ink printing is affected by printing conditions. Surface characteristics of the substrate. Ambient temperature and humidity; The influence of objective conditions such as the storage time of ink painting, so when using ink painting, it is necessary to use some additives to make minor adjustments to ink painting to obtain the best printing effect.
