The Focus Of Processing Color Saturation Of Packaging Printed Matter

The focus of processing color saturation of packaging printed matter

How to match the saturation is an important part of color processing. For time-sensitive and packaging products, the saturation of the color is particularly emphasized, reaching an excessive level, so that the color has a strong visual impact to satisfy the viewer's appreciation and pleasure. In color processing, some pictures can compress various colors in the same amount or lose a certain part of the color, strengthen the color of another part or the main part, and some pictures can keep the saturation of all colors balanced, according to the content of the original and the main body. Optimal handling of color conditions. The methods and essentials are as follows:

1. Depth basic primary colors are sufficient

1) Make full use of various solid color blocks, such as red, green, blue and other colors of headers and logos, and basic colors that do not require depth. Generally, customers require strong and bright colors for these headers and logo patterns. . In theory, it is to give full play to the extreme effect of the maximum solid density of the offset printing ink to achieve the maximum saturation. Although 95% of the dots will increase to 100% after printing, this is not the same as the effect produced by 100% solid printing. 95% of the dots only reach solid density in 95% of the dot area, while the increased 5 Although there is ink in the % area, the ink density is thinner. 95% dot gain to 100% ink density is not as thick and vivid as 100% solid density.

2) The colors of blue sky, ocean, green leaves, and lawns in landscape photography images, because a fixed concept has been formed in people's minds. Therefore, in color processing, in principle, the color volume of the C version should be deepened on the basis of the required color volume of the hue. Some, and green leaves, lawns and other greens, the Y version is also, making the green saturated and bright. For the basic colors of red, green, and blue depths that require layers, according to the color shift and gray characteristics of general offset printing inks, the optimal saturation configuration is:

Red=M95%+Y85%

Green=Y95%+C85%

Blue=C95%+M80%

3) The configuration characteristics of the dot value of the blue sky: First, do not put Y color below 40% of the C color version to make the sky blue more beautiful; second, put some Y color above 50% of the C color version to make the sky blue No redness, but a calm and thick blue. At the same time, since the sky blue ink used now is reddish, the red color is consciously reduced to make the blue sky more beautiful.

4) The red leaves of Xiangshan in autumn can be processed to be redder than the actual red leaves. The depth basic color Y is 100%: M is 95%, and C can be left alone, so that the red leaves look particularly beautiful under the sunlight, giving people a pleasant feeling of transparency.

The above-mentioned change in pursuit of color breaks through the traditional color matching method and highlights the aesthetic value of color in visual art.

2. Deep basic color preservation level

1) The dot tone value of the depth basic color ranges from 65% to 90%. Since the dots increase more than 80%, the layers are easy to merge. Therefore, the basic color of the hierarchy is required for this area. Under the premise of emphasizing the solid density, the layers should be maintained, and the saturation of the solid density should not be emphasized, resulting in the level of the basic color. Processing essentials: The depth of the basic color that needs to be layered, the focus is to moderately reduce the color volume in the area above 80%, so that it is separated from the solid color block, so that the printing can not only print the solid density, but also maintain the layer. .

2) In color processing, it is difficult to balance the brightness and saturation of the color with the light and dark levels in the color. If you want to preserve the light and dark levels in the color, you must use complementary colors, and when complementary colors are used, the vividness of the color will be reduced. decrease, grayscale increases. If you want to make the color vivid, it is necessary to put less complementary colors, so that the light and dark layers in the color will be affected. For timeliness and packaging products, emphasis should be placed on the saturation and vividness of colors, affecting the light and dark levels of some colors. In this way, the final printed image has a strong sense of color and a good visual effect. The key is to grasp a "degree", and the grasp of "degree" is the performance of the operator's aesthetic level, which is directly related to the artistic effect of color.

3) The layered texture in the depth basic color is mainly expressed by the main color version, such as red, orange and other warm colors: it is expressed by Y, M color version; such as green, cyan and other cool colors, it is expressed by C color version. Therefore, the layered texture of the main color version must be emphasized, and the characteristics of the physical layered feeling must be vividly displayed.

4) The basic colors in the middle tone area are sufficient. The midtone area has a tone value range of 35% to 65%, which is the main part of most objects and the key area of color processing. To adjust the basic color of this area to the best saturation, the essentials are based on the amount of color required by the hue. Darken it by about 5%, such as safflower, its bright and mid-tone M color needs a color volume of 40%, and can be deepened to 45% to make the red more saturated and bright.
