In fact, you only need to increase the rising angle behind the curve in

the color software to solve the problem. The specific rising angle value

needs to be adjusted by the technical personnel according to the color

status of the customer's pattern, only until it reaches the required standard.

In addition, sometimes the image output by the uv flat-panel printer will

suddenly fade. There are three reasons for this problem:

1. Influence of material. The transparency, glossiness, smoothness and other

characteristics of the substrate itself will affect the final uv flat printing effect,

resulting in some light and some deep output images. In addition to the visual

error of the naked eye, some materials can absorb ink, and some materials

can dissolve ink.

2. The ink volume in the print setting is too low. Generally, there are 40%, 60%, 80%,

100% and other different ink output controls in the image control software of

the uv flat-panel printer. If the operator is inexperienced, he will print the original

100% ink volume with 80% ink volume, which will cause the output image to be faint.

The solution is to increase the ink volume.

3. The printed PASS is too low. The color and accuracy of the patterns printed by

different PASS are different. Generally, on objects with smaller materials, high pass is

used for printing, which can make the patterns clear and colorful. If it is a large-format

printing, lower PASS can be used for printing.
