What is involved in the four -color printing process?

The four -color printing process usually begins by creating four screens, each of which represents a different color applied to the printed image. These four colors are cyan, purple, yellow and black (CMYK); "K" means black, rather than a letter "B" to avoid confusion with "blue". Each of these colors can be applied to a sheet of paper separately so that the combination of all four creates a final picture. Some modern devices can use the four -color printing process that applies all these colors at the same time rather than passing through one sheet of paper over four individual phases.

essentially four -color printing uses individual layers of color that combine and overlap to create a complete image. The first step in this process is usually for the image to be deconstructed on four screens that represent each layer of color found in it. It was once done on the photographic film sheets, although modern technology allows digital separation of the color to be done usingcomputer software.

The four colors used in the four -color printing process require a separate layer or screen for each. Cyan is a light blue color, while purple is light red, which is slightly similar to purple. Yellow is a standard color and between these three, there are many other colors that can be made. Magenta and yellow combine harvester to make red, yellow and cyan green and purple and cyan. Black is used in the four -color printing process to allow other tones and shades in these combinations.

Rule, standard four -color process uses a single print plate or color application to create an image. One sheet of paper passes through the application of each color, starting with Cyan, then moves to purple and yellow, before finishing black. Other applications or coating can be used on T, often protect ink and give it a glossy look. After they are tY these colors are used, the image is complete and the individual layers of the pigment are essentially imperceptible.

, however, the printing technology has allowed the four -color printing process to be performed in one stage. All four pigments can be used in one step, allowing them to combine smoothly and create a picture. This process is used to print full, pulsating colors for use in commercial applications. However, processing with one procession is quite expensive and as a result is not as common as traditional techniques.
