Common questions before printing problems

Common questions before printing problems

Plate making, the original to into green (C), magenta (M), yellow (Y), black (K) four color, the color separation principle? What?

A: color painting color photographs, the picture or the number of color thousands of. If you want to put the thousands of kinds of color printing a sexy, is almost impossible. Printing was by the four-color printing method. The first will manuscript color decomposition, divided into green (C), magenta (M), yellow (Y), black (K) four colored version, and then again when printing color synthesis. The so-called “color” is according to the JianSeFa principle, use red, green, and blue colour filter to three different wavelength of colored light has the characteristics of selective absorption, and place the original decomposition for yellow, product, green primary colors. In color separation process, colour filter is absorbed is color filters, the complementary color itself light so in photographic, black and white image formation of any of the negative, and network, to form a network of the negative, finally, sun into a plate of copy. This is the earliest photography color separation principle.

Due to the development of the technology of printing, now we can through the scanning equipment before printing manuscript color color separation, sampling and translated into digital information, is using the same method with photoengraving manuscript color into red (R), green (G), blue (B) three color, and digital, then use the computer through the mathematical calculation decompose the digital information for green (C), magenta (M), yellow (Y), black (K) four color information.

Why to want to add before printing image network?

Answer: because the printing process determines the printing can use network of continuous adjustable levels reappearance, figure if see, you will find amplified by countless vary in size of the network. We see dot size, but although different occupy the same size space, this is because the original image is a net increase, after image segmentation into innumerable regularly arranged that network, and the continuous adjustable image information into discrete outlets image information. The performance of the network, the darker the dark, level; The smaller the performance of the network, the color is more shallow, said the level of light. Each node has fixed position size is the space with the decision by the number of Internet, for example, add number for 150 lpi dot net, in an inch of length or width has 150 outlets. Network of space and dot size are two different concepts, such as C50 % representative is the meaning of dot size accounts for 50% of the network space position, 100% is to point to dot size all space, which cover network printing mentioned in “field”, 0% with no network, and the only network space position, so the this place is no ink was printed on. Obviously, the greater the number of outlets mesh hang space occupied by the small, can describe position of the more levels, more exquisite. In fact, the original manuscript of the level and the colour that through this hang nets method was reappear.

What is printing color?

A: printing color is different from the C, M, Y K and composed of the percentage of color, so called mixture color is more reasonable. C, M, Y, K is usually used in printing four primary colors. In printing, the four primary color all have their own color version, in color version on the record the color of the network, the network is tonal nets screen by half of the generation of four color version, and together they form a defined primary colors. Adjust the color version of the network size and spacing in can form the other primary colors. In fact, in the four on paper printing color is separate, just very close, because we are in the eyes distinguishing ability to have certain restriction, so tell not to come out. We get visual impression is all sorts of color is mixed effect, generating all sorts of different primary colors.

Y, M, C can be synthesized almost all color, but still need to black, because through the Y, M, C produce black is not pure, in the printing more pure black to, and if use Y, M, C to produce black can appear too much ink. Local
