“PASS”—What’s meaning in UV printing?

In English, “pass” means “passing”. Will “pass” in the printing device be straightforward?! It can be said here, no. In the printing industry, “pass” refers to the number of times the screen needs to be printed (the number of masks per unit area). The higher the PASS number, the slower the printing speed, and the better the relative quality. Otherwise, the uv printer is usually used. In inkjet printing equipment, 6pass and 4pass printing are more common. For example, if you play a 4PASS map, each pixel needs to be divided into 4 masks to print. Usually, adding PASS number can improve the picture quality. PASS means that the printout is completed when printing. The inkjet is a line printing method, 4PASS is 4 times printing, and so on.

A few passes of inkjet is required to complete the print area. Different stacking points for different pass points will be different, and the colors will be different. PASS usually has controllable options on the relevant uv printer and printer control software. For example, the RIP printing software of the uv printer can print the PASS according to the needs of the user. Output a perfect picture effect. The PASS number is related to the printing accuracy, and the difference in the printing accuracy PASS number is different.

How to solve the phenomenon of pass channel drawing in uv inkjet printer?

The difference is the PASS road, or the disconnection. If you don’t understand these two concepts, there is no way to provide assistance. When you say the PASS channel, please stop printing immediately, and then print the test strip directly. If it is broken, look at the broken colors. If the broken color is the color of the margin part of the nozzle, you can think about it. The pump composition does not match print head, and the orientation of the two can be adjusted according to the specific situation. If the ink-breaking method is used in the middle of the nozzle, the pipeline should be considered, especially if the ink capsule is used for a long time. maybe the ink sac and the nozzle’s socket are not tight enough, there is a leaky scene? Maybe your ink may be of poor quality (some inks are not very fluid and will break the ink)
