What kind of paper do you use for film wrapping?
The film is black, a English general film corner symbols, is the number of film, C, M, Y, K in which one is that the film is one of the CMYK (or spot number), said that this film is what if there is no color output. You can see, mesh point of view, is to identify what color. The ladder next to the bars are used for dot density correction.
Lin is the film, is an ancient translation of film, and now generally refers to film, can also refer to the printing plate in the negative. The plate in printing is also called film paper.
In addition to color dot density is normal, or a is CMYK, color is C in the lower left corner, the stripe in the upper left corner is M, in the upper right corner is Y, in the lower right corner is K, so as long as the color printing factory that CMYK. That is to say, in order to conveniently test the concentration of the film developing, the color of the film has a color number. And as to how many colors are printed, according to the net of each film.
Next to the color code can not indicate the specific value of CMYK, but the contrast used to test whether the film out of line with the requirements. A habit is finished (cutting line, line set, the name of each line) and each version of their own version of the color mark. For example, labeled C, M, Y, K, silver, and then fill in the blue, red, yellow, black and spot color version of the spot color, so that the film out of the logo, and particularly intuitive. The size of the color code 10*5mm, and put on paper CMYK letters in English, the color block and color name one by one correspondence. It's OK for the printer to see the corner of the forest. Generally speaking, the dot angle of the film is fixed, just like the net angle of the yellow version is 90 degrees. There are exceptions, if the Yellow expression of the image is concentrated in the range of 90 degrees, then yellow can not use 90 corners. Otherwise, the traces of the nets are too obvious!
