If the uv printer is used, it is found that the printed substrate sometimes has a lack of color. When this phenomenon occurs, as long as we do a good job of maintenance, we can reduce the occurrence of color deficiency. The following is the solution to the problem of lack of color.

1.When we start printing every day, you should test it with white paper or other items. When it is determined that the pattern and color of the printer are complete,you can proceed with the work.

2.The lack of color in a short period of time caused the lack of color. We first extracted the waste ink, and then inspected and cleaned the nozzle. However, it should be noted that the cleaning of the nozzle should not be too many times, less than three times.

3.This phenomenon occurs if the printer has not been used for a long time. Then we will use a special nozzle cleaning liquid to clean the nozzle. Here, stormjet printer reminds you that we must use the cleaning liquid recommended by the manufacturer. Do not use other cleaning liquid at will to avoid irreparable damage to the nozzle.

4.Check whether the continuous ink supply has not been cleaned for a long time and there is a lack of color. We will thoroughly clean the ink bottle and ink cartridge corresponding to the lack of color. Then refill the ink. If it still appears, then we need to replace the continuous ink supply.

5. Use drawing software to create color patches of missing colors, and then repeatedly print, can also play a certain effect.
