Some pictures printed by the large format uv flatbed printer may have different colors from the computer. Why is there a color cast? Here is a introduction to the reasons for the color cast.

1.If you want to compare, you can’t expect the pictures printed by the large format uv flatbed printer to be exactly the same as the color on the computer, because the monitor is RGB true color with a wide color gamut, and the large format uv flatbed printer is CMYK false color so the color gamut is narrow, and the software automatically converts the mode. Some colors will be lost, which is normal. 
The general solution is to adjust the color cast. The method is to reduce the amount of yellow in the Y channel, and make multiple adjustments each time. Of course, you can also ask a master to help you adjust the curve, and save it when you are satisfied.

2.Before printing, please check whether the mode of the picture in Photoshop is RGB or CMYK. When outputting pictures with a large format uv flatbed printer, change the mode of the picture to CMYK.

3.Color distortion is also related to computer color management, display resolution, printer resolution and printing media.

4.If the large format uv flatbed printer you use needs to be equipped with 4 or more print heads, please check whether it is the same brand. Because the ink colors of the same brand have good complementarity and coordination, so as to ensure the reproduction of its color.

5.Check whether the large format uv flatbed printer head is broken and the large ink bottle is out of ink.

6.Please check whether it is set to save ink or resume printing.
