Neutral gray balance is very important because it can ensure the correct reproduction of the original style during the printing process. In order to ensure the neutral ash balance in the printing process, it is necessary to understand the influencing factors of neutral ash balance. Now, Jinan Printing Editor will explain it to you.
First of all, we need to understand the law of color change. Three primary colors ink can be mixed with approximate black according to a certain proportion, and then with different proportion of diluents, we can get neutral gray of different colors. The three primary colors can be mixed in different proportions to obtain intermediate or multiple colors of different hue, and the hue is biased to the hue with large proportion.
The performance of paper is related to the neutral gray balance. The product quality of printing enterprises is greatly affected by the raw material paper. The ideal paper whiteness is 100% reflectivity, and the total reflection is 380~700nm.
In the process of plate making and printing, it is necessary to consider "different from paper to paper", and adopt the appropriate process content to adapt to the paper used, especially in terms of the thickness of the dot, the number of overprinting, the size of the page contrast, etc.
For the relationship between printing color sequence and neutral gray, it is first considered that the ink with low transparency is printed in one color, and then the ink with high transparency is printed. This color sequence is arranged according to the transparency of the ink.
At the same time, considering the viscosity of the ink, it can avoid the sticky dirt on the back of the printed matter; Light color is printed on the front, and it is easy to clean the ink roller; It also facilitates the accuracy of four-color overprint. The multi-color offset press is wet and overlapped. When the printing ink is dry without oxidation conjunctiva, another color ink is overprinted.
Different color sequence arrangement has a great impact on neutral gray balance, and different color sequence will directly affect the quality of printed products and color tones.
In the actual production, comprehensive analysis should be made to consider more variable factors involved in the printing process. In terms of color sequence arrangement, color sequence should be arranged according to different types of originals and the effect of printing required by customers, so as to meet the requirements of reproduction of originals.
