Why don't I print, I don't think I have any bearing on the film, but here the printing house still talks about a little common sense about the film, in order to facilitate some people who have no idea about this unknown friend.
Often, the angle of the dots of the film is constant, just like the angle of the yellow version is 90 degrees. There are also different, if the yellow expression of the portrait is concentrated at the boundary of 90 degrees, then the yellow angle cannot use the 90 angle. Otherwise, the trace of hanging the net is too clear! According to the usual reason, a color is produced, it is reasonable to play a color bar, in order to check in the process of the color of the non-forest process, the conditions of drying on each density ladder are very clear It is often four color bars, and the columns are very neat.
Most colors are taken by these four-color combinations, then a film is black, but the color difference of their confession is C, M, Y, K. Look at the ratio to know. The outlet on the film is to tell you "What kind of colors are there at this level?" For example, often the text version has only one black, and the version has only one film. If you print in red ink, the printed word is red. A film film only What kind of color represents, and the printing is colorful, there must be at least 4 films, which represent C, M, Y, K4 colors! It may be four spot colors, the spot color film is input into K with its own file Version.
The nearby color scale does not express the overall value of CMYK, but is used for comparison. Check whether the film is suitable for the conditions. Some people are used to drawing the corner lines (cutting lines, registration lines), and then I use the solid colors on each version. Mark the title of each version. For example, mark C, M, Y, K, and spot silver, and then fill in the spot colors on the blue, red, yellow, black, and spot color versions, so that the film that comes out has all The logo is special and intuitive. The size of the color scale is 10 * 5mm, and the English letters of CMYK are printed on the paper. The color blocks and color titles correspond to each other. The printing workers can look at the corners of the film.
Films are all black, and film corners often have an English mark, which is the film number, indicating which film is C, M, Y, K, which is one of cmyk (or spot color number ), Confess what color this film is input, if not, you may wish to look at the angle of the hanging net to distinguish what color. The nearby stepped color bar is used to correct the dot density. Except for the color bar, see the dot density Whether it is normal, still one is to look at 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 only based on the color bar printing factory know CMYK That is to say, in order to facilitate the inspection of the concentration of film development, there are color numbers on the corners of the film. As for the number of colors printed, it depends on the screen line of each film.
