The film is black. The film's corner usually has an English symbol. It is the film number of the film. It indicates which of C, M, Y, and K is the film. It is one of the cmyk (or spot color). , which means the film is what color output, if not, you can see the angle of the hanging net to identify what color. The next stair-like strips are used for dot-density calibration. In addition to seeing whether the dot density is normal or not, one is to see CMYK, the color bar is C in the lower left corner, the color bar is M in the upper left corner, Y is in the upper right corner, and K is in the lower right corner, so long as the color printing factory You know CMYK. That is to say, in order to facilitate the detection of the film developing concentration, the film sheet has a color number on the corner. The number of colors printed depends on the screen of each film. The film outlet on the film is to tell you that "here there is a certain degree of color." For example, the general text version is only black, and there is only one film in the print. If you print in red ink, the printed word is red. A film film represents only one color, printing color, at least four film films, representing C, M, Y, K 4 colors! Can also be four spot colors, spot color film is a separate file output into K version. Next to the color code can not show the specific value of CMYK, but used in comparison, to check whether the film meets the requirements. Some people are accustomed to drawing corner lines (cutting lines, register lines), and then using their own solid colors to mark the names of each version. For example, marked with C, M, Y, K, special silver, and then fill in the blue, red, yellow, black and spot colors on the spot color, so that the film came out on the label and is particularly intuitive. The size of the color scale is 10*5mm, and the English letters of the paper color CMYK are printed. The color patches and the color names correspond one by one. The printing workers can see the edges of the film. In general, the film's dot is fixed, just like the yellow version's screen angle is 90 degrees. There are exceptions, if the image's **** expression is concentrated in the 90 degree range, then **** can not use 90 angle. Otherwise, the traces of the net is too obvious!! By the usual sense, a color, A color bar should be struck, and in turn, to check that the process of drying on each density step is clear in the process of coloring out non-forests, it is generally four color bars, and the arrangement is very neat.
Most colors are based on the combination of these four colors, then each film is black, but they are different colors C, M, Y, K, see the proportion know, and then by printing four-color ink.
