Screen printing ink refers to all inks called screen printing ink when screen printing is used. \x0d\ can be divided into fluorescent ink, bright ink, magnetic ink, conductive ink, fragrant ink, sublimation ink and transfer ink. \ x0d \ x0d \ oil adjustment method: \x0d\ 1. The mixing method of equal mixing of two primary color inks is called the mixing of intermediate color inks. Indirect color, also called secondary color, is darker than primary color. The mixing rule of halftone ink is: yellow+magenta = red [(w-b)+(w-g) = (2w-g-b)] magenta+cyan = blue [(w-g)+(w-r) = (2w-g-r)] yellow+cyan = green. According to the principle of pigment subtractive method, the following rules are adopted for the preparation of three primary colors of ink: ① When two primary colors of ink are mixed, if the mixing ratio is equivalent, a standard intermediate color can be obtained; If the mixing ratio is not equal, you will get a variety of shades, and their colors are biased towards the side with a large proportion. (2) Adding Bai Mo into the color of equal mixing of two primary color inks makes the hue bright and vivid; Adding black ink will darken it. (3) When the three primary colors of ink are mixed, if the mixing ratio is equal, the approximate black color can be obtained; If the mixing ratio is not equal, you will get a variety of intermediate colors or composite colors with different hues, with the hue biased towards the larger one. (4) When the three primary colors of Oriental ink are mixed equally, different proportions of Bai Mo can be added to obtain light gray inks with different tones. \x0d\\x0d\3。 Unequal distribution of intermediate colors and complex colors ① Unequal distribution of intermediate colors: magenta 1+ yellow 1 = red, magenta 1+ yellow 3 = dark yellow, magenta 3+ yellow 1 = golden red yellow 1+ cyan 65438. Yellow 4+ cyan 1 = apple green magenta 1+ cyan 1 = blue, magenta 1+ cyan 3 = deep blue, magenta 3+ cyan 1 = purple ② The composite color is not equal to yellow 1+ magenta/kloc. Yellow 1+ magenta 4+ cyan 1 = reddish brown, yellow 1+ magenta 2+ cyan 1 = olive green, yellow 1+ magenta 1+ cyan 4 = dark green. \x0d\\x0d\4。 The color method which consists of two intermediate colors or three primary colors mixed in equal amount is called multicolor ink mixing. Multicolor ink is also called the third color, and its mixing rule is: red+green = yellow gray [(y+m)+(y+c)] = [y+k]. Yellow-gray is commonly known as bronze. Red+blue = red gray [(y+m)+(m+c)] = [m+k]. Red-gray is commonly known as bordeaux. Blue+green = cyan [(m+c)+(y+c)] = [c+k]. Blue-gray is usually called olive green. \x0d\\x0d\ Ink color matching methods include: \x0d\① empirical method to adjust ink color. Make full use of ten colors: yellow, magenta, cyan, red, green, blue, black, purple, bronze and olive, and add a Bai Mo, or use printing process to prepare. \x0d\② Computer Toner Ink. Use color spectrophotometer, computer and its matching color matching software for deployment.
