To judge the color accuracy of a UV flatbed printer, you can refer to the following steps:
1. Print solid color patterns:
Printing solid color patterns can test the color accuracy of the UV machine.
Observe whether the color of the printed pattern is uniform and there is no color difference.
2. Check the sprinkler status:
Print the state diagram of the sprinkler head, and judge whether the state of the sprinkler head is good by observing the color.
3. Ink quality:
Different manufacturers of ink composition and proportion are different, which will affect the printing color.
Make sure the ink is of good quality and free of impurities or expired.
4. Check the color coverage:
Print four-color, six-color, eight-color patterns respectively, and check whether the device supports multi-color printing.
The absence of a certain color of ink (such as white ink) will result in a yellowish print pattern.
5. Software system test:
Print gray gradient color, identify whether the software system of the equipment is perfect.
-ICC color curve is normal, which affects the color performance on different materials.
6. Print height detection:
Test the performance of the device within the actual printing height range.
By increasing the material height, the printing accuracy and inkjet positioning accuracy are observed.
7. Equipment stability:
Observe the fuselage structure and judge the smoothness.
The body with small vibration amplitude is conducive to maintaining printing accuracy.
8. Color richness:
The human eye can distinguish about 500 million colors, and the higher the color richness, the more natural the print effect.
9. After-sales service:
Choose a UV printer with good after-sales service and warranty period, such as Toshiba brand UV printer provides a two-year warranty.
Through the above steps, you can evaluate the color accuracy of UV flatbed printers in a more comprehensive way.
