Some friends always feel that when scanning images, there will be insufficient contrast, insufficient clarity, and color cast. These may be caused by poorly set black and white fields during scanning. In general, the so-called "highlight point" should be: the brightest point in the image where the brightness level starts to appear, but it is not the locally brightest "extreme highlight point". "Dark point" is generally the end point of the dark level of the image, but it is not the darkest point. Copperplate paper printing requires that there should be no bright spots in the bright tone (that is, the four-color dots are all 0), so be careful when selecting highlight areas. The setting values ​​of the most bright four-color are: C5, M3, Y3, K0, Or it can be brighter: C4, M2, Y2, K0, if the original is too bright or too dark, the setting value can be changed, but it should be ensured that the value scanned by the brightest spot is basically the above value, and there can be no network phenomenon . The setting of the black field should pay attention to the total amount of ink for ordinary offset printing is 320 ~ 360, too thin will cause the color of the printed image is not saturated, the color is not bright, and the dark tone part C version must be greater than the M version and Y version, and The K version cannot be less than 80, otherwise there will be color cast, dark tone and gray. The general setting values ​​are: C90, M85, Y85, K80. If the printing factory is in good condition and the requirements of the printed product are high, you can do: C95 , M90, Y90, K85, such prints have good contrast and rich levels. Newspaper printing is a rotary printing machine with fast speed and short ink drying time. Therefore, the ink should not be too thick during the copying process. The total dot area ratio of the four-color printing should be limited. At the same time, a larger proportion of gray components should be used instead. . According to the characteristics of newspapers, the minimum dot area rate that can be completely transferred to newsprint is between 6% and 8%. When selecting highlight points, the area ratio of the highlight dots of the image should appear not less than this range, otherwise the transmission of the highlight dots will be incomplete or completely lost, so that the originally layered highlights of the image will become white. The highlight of the paper. The dark tone point can not be like ordinary offset printing, the total amount of ink can only reach 270 ~ 300, so it can be set to: C60 ~ 65, M50 ~ 55, Y50 ~ 55, K90 ~ 95
