#Introduction to spot color separation full
Its quality requirements are firstly that the substrate has good light transmission performance, secondly, the image shading density is high, and thirdly, the registration accuracy between the color separation films must be accurate, and the edges of the image lines are clean and tidy, and the dots are full and clear. The color separation plate-making draft is used to make the corresponding color separation screen printing plate by sensitization. It is not the primary color printing but the spot color screen printing, that is, the multi-color spot color screen printing is performed on the color, especially the black T-shirt. However, with the development of screen printing technology and the development of new inks, spot color screen printing has emerged in recent years, especially in T-shirt printing, the latest international T-shirt pattern and the most advanced T-shirt printing technology. Spot color printing is mainly used for color block printing, and its reflection on the natural scene can only be simulated rather than restored, which is the biggest difference from primary color printing. However, the number of spot colors is not equal to the number of colors in the image, because spot colors can al so be overprinted, so five spot colors can also be printed with six sets or even seven colors and eight colors. We usually talk about five-color printing and twelve-color printing, which means that five spot colors or twelve spot colors are sequentially printed to form color image printing products.
T-shirt design spot color separation refers to the use of any specially formulated color as a single printing color, and several such spot colors are processed by color printing to form a color image. T-shirt design color separation methods are mainly divided into two categories: spot color separation and primary color separation.
#Introduction to spot color separation manual
The image formation of the plate-making manuscript mainly adopts manual drawing, manual or mechanical engraving, photosensitive copy, laser phototypesetting, printer printing and other production methods. Therefore, the draft must be drawn on a light-transmitting substrate, and the image is an opaque ink layer (black or red), the light-transmitting property of the substrate and the shading of the ink layer Density is a key indicator that determines the quality of the plate-making manuscript. Its main function is to make a photosensitive printing pattern. Plate-making drafts can also be called black-and-white drafts, color separation drafts, and plate-making negatives.
