There are always color requirements for the injection mold during the use of the mold, so how to deal with the color of the injection mold?
The printing process of gravure goods color plastic packaging products, the printing process is ultimately the color reproduction process, and the most fundamental of them is whether the image color processing technology of the plate making company is excellent, whether it can bring out the image that the customer is satisfied, and can exceed the customer's expectation. color. Because the customer first looks at the color of the image is not good, the color is not bright; compared with the original, the color does not look like; the color that he hopes for is inconsistent with the color that he hopes to judge the quality of the plate. At the same time, in the packaging art, there is often a saying that "looking at the color and looking at the flowers, looking at the color and then seeing the flowers, and the seven-point color is three-pointed", which fully shows how important it is to handle the color of the plastic packaging products. Therefore, the proposed guiding ideology and method are: according to the theory of plastic packaging printing color theory, give full play to the limit of gravure process and the viewpoint of satisfying people's psychological color requirements, combined with the color characteristics of commodity packaging products, according to color configuration Principle, color processing according to the law of gravure printing. Overcoming many current sewage treatment equipment operators just look at the screen color random, blind color, sometimes lemon color is also orange, resulting in repeated rework. Therefore, it is important to master the ten methods and methods of color processing.
Color saturation processing
How to match the saturation is an important part of color processing, because customers are required to have saturated colors and sometimes very demanding conditions. In fact, in processing, it is possible to compress various colors in an equal amount or to lose the color of another part, and to enhance the color of another part, sometimes to balance the saturation of all colors, and to preferentially process and master according to the original content and the subject color. The following essentials:
Deep basic color
Various solid color blocks such as red, green, blue and other solid words, logos and other patterns and deep basic colors that do not require gradation are required. Generally, customers require thick, thick and vivid colors. Therefore, 100% of the use should be 100% in the field, in order to give full play to the limit of the maximum solid density of gravure ink, can not be made 90% or 95% even though 90% and 95% of the dots are enlarged after printing 100 %, but this is not the same as the effect produced by 100% solid printing. 90% of the dots have a density in the 90% dot area, while the expanded 5% or 10% area has ink, but the ink is more Thin, density does not reach the effect of solid density, so visually, 90% or 95% of the dot density is 100%, and the ink density is not as thick and bright as 100% of the solid density.
Keep the level in the basic color of depth
1. The depth of the base color has a range of 65%-90%, and more than 80% is the area where the gravure dot enlarges the most, which is easy to cause level and level.
2. For the basic color of the area that needs to be leveled, under the premise of emphasizing the saturation of the solid color block, pay attention to maintaining the level in the basic color of the depth, and not emphasize the density and the fullness of the density in the field, and cause the depth in the basic color. Hierarchical level, can not pay attention to the level of the basic color of depth, and affect the lack of drinking and degree. In order to deal with the essentials, it is necessary to reduce the basic color of the depth required to be shallow, so as to open the distance with the density of the ground, so as to achieve the best of both worlds.
Need to pay attention to the red, green and blue optimal saturation configuration. According to the characteristics of surface printing ink, the optimum saturation of red, green and blue is: red = M95% + Y80%; green = Y95% + C80%; blue = C90% + M75% .
