Why do we repeatedly emphasize that customers and friends must print test strips before printing tasks? The main reason is that after printing the test strip, we can see from the test strip whether the status of the printing machine is normal. Only when the printing status is normal can one day’s printing tasks be carried out. If the printing status is abnormal and you have not printed a test strip for inspection, it is likely to cause a lot of defective products.
To solve the problem of lack of color in the printing pattern and the color mismatch of the pattern, we must first know where is the fault of the printing printer? There are mainly the following points, let’s find out together!
1. When the printing settings are correct, there will be deviations between the computer monitor color and the actual printing color. Since the computer monitor and white ink heat transfer printing machine use different technologies to express colors, namely RGB mode and CMYK mode, the actual printed color Cannot exactly match the colors expressed on the monitor.
2. The ink setting in the DTF printer driver is “black”, modify the setting and set it to “color”.
3. The printing medium setting is not consistent with the actual printing medium, modify the printing medium setting in the driver, or replace the matching printing medium. If the media is face down, load the print media correctly with the print side facing up.
4. The ink in the ink cartridge is low, and one or more colors of ink are empty. Check the ink cartridge to determine whether it needs to be replaced.
5. The midtone and mode selection does not match the file type, and the mode setting does affect many other settings in the driver. The middle tone setting determines how the dtf printer sprays ink droplets onto the printing film. If it is not set properly, it will cause color deviation.
6. If the nozzles are clogged, some nozzle holes will not produce ink, which will also cause a lack of color in a certain part of the printed pattern. You can use the automatic cleaning system that comes with the printing machine to clean the nozzle twice repeatedly. If it can’t be improved, then you need to use cleaning fluid to clean the nozzle.
DTF printer may have various failures during operation, and it may be caused by various reasons. The above 6 points are the main reasons for the lack of color in the white ink heat transfer printing pattern. Customers and friends can check the above problems one by one and make corrections. If the problem still cannot be solved, you can contact professional maintenance personnel to deal with it!
