What are the quality factors of the pattern?

The quality of the pattern is mainly the two aspects of the definition of the pattern and its color. Sharpness refers to the type of handwriting, the thickness of lines, etc., giving people a sense of whether it is clearly visible, not chaotic, even and so on. The chroma of a plate, commonly known as blackness, refers to the depth of the toner used for graphics and writing on the surface of the plate.

The clarity of the layout is very easy to do for publishing staff. If any quality problems are found, they can be corrected at any time. The color of the pattern is not easy to grasp, only professional personnel can judge. In some special cases, it is necessary for the publication-like personnel to adjust the thickness of the writing and the amount of toner at any time according to the actual situation. If the surface of the pattern is a very fine line, the publishing staff should increase the thickness of the line (or increase the line number) and adjust the amount of toner properly. Otherwise, although the line can appear on the pattern, it gives a feeling of It is very clear, but it is because the lines are too thin. The printed plate that is made is not very resistant to printing force. Sometimes it is peeled off during the imposition because its adhesion is not strong.

The depth of shades of the plates affects the normal exposure time and development time of the PS plates for the plate makers. The exposure time of the plates is for the entire plate, not part of the plate. If the chroma of a certain part of the pattern does not meet the standard, it will affect the normal exposure time of this version, or at the same time due to overexposure, the resistance of this part is lower than other parts. If the exposure is according to the standard of this part, other parts will be underexposed.
