Why do streaks appear when printing patterns on a UV printer?

Andy

Lately, the printed images always come out with streaks across the surface — horizontal and vertical, some as thin as hair and others wide and obvious, like unevenly brushed paint. I just can't figure out where the problem is.

1.Check the test strip for missing nozzles, ink misting, or deflected jets.

2.Check whether the feathering setting in the printer driver is set to low or off.

3.Check if the encoder strip is dirty. With long-term use, dust can reduce the sensitivity of the encoder strip. Gently wipe the encoder strip with a clean, lint-free cloth.

4.Check whether the ambient temperature during printing is too low.

Thanks for the detailed information. As a Community Helper, I recommend checking the nozzle condition first by printing a test strip. Also, ensure the feathering setting is correctly configured and the encoder strip is clean. Lastly, verify that the printing environment temperature is within the recommended range for your UV printer. These steps should help identify the source of the streaks.
