Neutral gray balance is very important because it ensures the correct reproduction of the original style during the printing process. To ensure neutral gray balance in the printing process, it is necessary to understand the influencing factors of neutral gray balance. The following is an analysis by Shandong printing and packaging manufacturers:
First, it is necessary to understand the law of color change. Three primary inks can be mixed to approximate black in a certain proportion, and then different proportions of diluents are added to obtain neutral grays of different colors. Mixing three primary colors in different proportions can result in different shades of intermediate or multiple colors, which tend to be larger in 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% reflectance, with a total reflection of 380 to 700 nm of light. In the process of plate making and printing, it is necessary to consider "paper specific" and adopt appropriate technological content to adapt to the paper used, especially in terms of the thickness of the dot, the amount of chromatic register, and the size of the page contrast.
The relationship between printing color order and neutral gray is first considered to allow low transparency inks to be printed on the first color, followed by high transparency inks. This color order arrangement is arranged according to the transparency of the inks. At the same time, ink viscosity is also considered, which can avoid the phenomenon of sticky dirt on the back of the printed matter; Light colors are printed on the front, making it easy to clean the ink roller; It also facilitates the accuracy of four-color overprinting.
Multicolor offset presses are wet stacked, and the printing ink is overprinted with another color ink without drying the oxidation film. Different color order arrangements have a significant impact on the neutral gray balance, and different color orders directly affect the quality of printed products and the hue of colors
In production practice, it is necessary to comprehensively analyze and consider some variable factors involved in the printing process a little more. In terms of color sequence arrangement, it is necessary to arrange the color sequence according to different types of originals and the effects of printing required by customers, in order to achieve the requirements of reproducing and reproducing the originals of printed products.
