A printing company can print many things, such as color picture album printing, brochure printing, magazine printing and so on. So what should we do about color biasing in color album printing? Now let's follow Xiaobian to understand it.
To deal with the problem of color bias in color album printing, we must first know the elements of color bias in color album printing. The elements of color bias in color album printing are as follows:
There are different levels of color deviation in the three primary ink, which will have different levels of color deviation effect on the whole picture. But a small amount of color deviation can be corrected from the aspect of ink preparation. When printing, it is necessary to balance the gray of the ink used. The equal amount of yellow, grade and green does not produce neutral gray. They produce light, turbid and brown gray, rather than real gray. The reason is that the ink introduced above is not ideal absorption of color light (the spectral curve of the ink is not ideal), that is, caused by the impurity of the ink used. In the CMYK space of practical ink, in order to get real grey, we need to improve the amount of blue ink.
2. Paper itself
It is the smoothness, absorbability, whiteness and gloss of paper that have great influence on the reproducibility of tone and color of printed matter.
The smoothness is divided into apparent smoothness and printing smoothness. Apparent smoothness is the level of paper surface smoothness. It depends on the appearance of the paper, and describes the structure characteristics of the paper surface. The paper's apparent smoothness has a certain relationship with its glossiness. The paper with high apparent smoothness has a relatively high glossiness. Understanding the elements of bias will enable us to know how to stop dealing with him.
For a part of the category, the corners of CMYK without holes (light leakage) must be completely non-scratched and without obvious scratches. The proof must be substantially reduced and the obligation to correct it. Signature notes, paper making, printing quality, delivery time, process requirements, can not be slackened.
Pay attention to the chromaticity of color album printing; version (CMYK corner line is not aligned, using a magnifying glass, you can see errors) 1,2 lines; pay attention to, there is no obvious dirty spots, it should be noted that at any time, the color album printer erases the part of the printing plate; pay attention to the printing of unnecessary white spots or other color points, erase at any time; every part of the printing workers will be pumped out. As you come out, you can also run the color album printer for a period of time according to what you see, which may be a phenomenon of light or heavy tasks of a certain color.
This is where you can see the treatment of color bias in color album printing. I hope our introduction can help you understand more information about color album printing. Please continue to pay attention to our official website: http://www.ionexplorer.com.
