How to Scan and Separate Colors in Color Newspaper Printing

1. Bright and colorful. In order to reflect the propaganda effect of color newspapers and take into account the printability of color newspapers, it should be appropriate to make the colors pure and saturated. In Photoshop, we can increase the saturation and improve the basic color in spot color correction, and reduce the opposite color.

2. Strong contrast. The maximum density of newsprint printing is only about 1.2. The highlights of the paper have a background color of the paper. The deepest point is also thin due to the relationship between high-speed rotary printing. The operation can be properly compensated by the method of calibration and partial deflection. White field Department can give up part of the high light level, taking into account the background of the paper, the depths of the dark field at the various color version of the foot, four-color ink superimposed to reach more than 360%, and sometimes even can be deepened alone in the black version of the dark tone at the outlet value.

3. Emphasize clarity. High-speed printing often produces imaginary halos, resulting in subtle levels of loss. Therefore, when the mask is sharpened, it can be slightly overdone, the character manuscripts can be weak, and the scenery and buildings can be stronger.

4. Under color removal. In the color printing process, the bottom color can also be used to reduce the amount of ink, which facilitates quick overprinting of the rotary machine, which is beneficial to neutral gray balance and makes the layout clean and bright.

5. Since manuscripts are influenced by time, transmission, and many factors of the equipment, this requires the operator to have a certain aesthetic view, so that the overall color picture must not be distorted, the color should be close to its real effect, and the black and white fields of the picture should be set. The area with extremely high light can be netted, but large areas should not be netted, and dark areas should be preserved.
