What are the reasons for the color difference between printed products and computer pictures?

In our daily customized products, how many always encounter customers asking why the printed product is different from the computer? This problem is actually the simplest problem in the printing industry, color difference! Well, today we will talk about why there will be color difference in the process of printing products.

Actually, color aberration is caused by a variety of reasons, so here is a summary.

1: The reason for the print head

The quality of the product print head directly affects the clarity of the entire product. This is the most direct impact, because a UV The core of the printer is the print head, so when you buy a UV printer, you must figure out the performance of the product print head you want to use. And regularly carry out the daily maintenance of the nozzle, try to ensure that the nozzle is not blocked.

Two: The cause of the ink

If the ink breaks during the printing process, the lack of ink will definitely affect the printing For the clarity and effect of the product, the ink normality test must be carried out before printing the product to ensure that there is no problem with the ink, so as not to delay the work efficiency of the whole machine.

Three: Picture problem

The degree of clarity of the pattern itself is also one of the basic factors that affect the color difference. In the process of selecting pictures and printing, ensure that the product has high-definition patterns. The higher the picture definition, the smaller the color difference printed.

Four: Body problems

If the machine has been used for a long time, the chassis and parts are unstable, which may affect the ink output, thereby affecting the quality of printing.

Five: Other issues

There may be some errors in the color of the computer display and the output of the UV printer. Besides, the color seen by the human eye and the color recognized by the machine will also be different. , These superimposed factors may cause the appearance of chromatic aberration. And this difficulty is inevitable.

The above is the reason for the difference between the printed product and the actual pattern effect. I want to say that the color difference is inevitable, but It can be avoided as much as possible. For example, the causes of human factors can be resolved through adjustment, but non-human factors cannot inevitably be dealt with. You can only wait for the emergence of higher technological products to solve such problems.
