The theory of color is very scientific, but I am not a scientific answer to what is color. I will be exposing how colors are used in the printing industry. Moreover, what is the abbreviation CMYK and spot color printing, as it is different?
I can not fix, color makes no mention of that is you can not see a light color. You can prove this, trying to see the color in a darkened room or dim light. An outline of this truth is the color we see is an image of a certain wavelength of light. The red color corresponds to a wavelength of red light, so you can see the color red, and this process brings each color.
We start with the simplest explanation first printing with special colors. The color of the ground term to describe the process, a printer used to make an image with 100% ink. If a tag or label must be printed in red and blue, a manufacturer of color printing, 100% blue and red mixed. These colors separated and not mixed with the substrate in a third color.
Spot color printing is simple and not complicated, there are some exceptions, like when you paint transparent colors overlap others. Most of us have this when we were kids when we used crayons coloring one color on top of another color to make a third color. The artist who paints in water or oil colors uses this process on the canvas or on their palette.
The most complex mechanism of four color printing, which will be printed in CMYK C.M.Y.K The acronym cyan, magenta, yellow and black. Blue is blue, red, magenta, yellow, natural, yellow and black is black. Sometimes these colors are known by their counterparts of Pantone, process blue, process, red, yellow and black process procedure.
The four-color process method of printing uses these four colors, by printing dots of each color on the substrate. Each point of the color displayed next to one of four colors at a predetermined distance and angle. The reflected light of each color mixed point, the observer can see the color of this region, which was intended.
The technology of the theory of four-color process color is different and independent use. TV uses the same theory, color printer, one of the images that you can use a color film camera or digital camera, magazines; you can add to this list, it would be preferable.
How can you say if I tell you the truth? The next time you get a picture or a magazine of the digital image will look carefully printed using a magnifying glass to see the image. The magnifying glass you can see parts of cyan, magenta, yellow and black in the picture.
He noted, finally, black is the absence of color and is in the process or be used as Definer shade. The color is a combination of all colors, and usually four-color process method of printing is printed on top of a white background.
I leave you with a question why is DPI or Dots per Square Inch important in the four-color process method of printing?
