What Is The Reason For The Color Difference in The Products Of UV Flatbed Printers?

The color difference of products printed by UV tablet printers is mainly caused by the following reasons: ICC curve, color adjustment, ink, software, and temperature. Let's take a detailed look together:
1. There is a problem with the color adjustment of the UV printer
Solution: Modify the original image, for example, use PS, AI, and CDR software to correct the color of the original image, then fill and compare the colors, and then perform one-to-one printing;
2. There is an issue with the ink of the UV tablet printer
Solution: Different types of UV ink have differences in color, saturation, brightness, and color gamut. Replacing with a new UV ink will inevitably lead to color problems in pattern printing, and a new color curve needs to be made. Secondly, due to different ink points, the printing side view needs to observe the status of the spray holes. If there is a blockage that causes ink output to be not smooth, the spray head needs to be cleaned. If it is an ink deposition problem, Because the internal color of UV ink that has not been used for a long time may cause sedimentation issues, it needs to be thoroughly stirred before use. If condensation or bonding occurs, it indicates that the UV ink has expired and needs to be replaced;
3. There is an issue with the ICC curve of the tablet printer
Solution: Restore the color ICC curve values to the factory settings. If they are not set, you can contact the manufacturer's technical personnel for remote guidance or modification. If you have replaced other types of UV ink, you need to remake the color ICC curve;
4. UV tablet printer is affected by temperature
The solution is that an external temperature between 15 to 30 degrees Celsius is a good temperature environment for UV printers. If the temperature is too low, air conditioning needs to be installed. If the temperature is too high, it needs to be cooled down;
5. The software of the UV tablet printer has malfunctioned
Solution: Reinstall the software of the UV tablet printer. If the value is incorrect, it needs to be restored. However, it should be noted that before reinstalling, the computer needs to be antivirus and the UV printer software should be added to the antivirus software's whitelist;
