![]() In actual fact, the black produced by combining cyan, magenta and yellow is more like a dark muddy brown, which is why the fourth color, black, is added for better color rendition and to make it easier to print type, most of which is generally black. The absence of any color leaves only the paper color which is generally white. In theory, add 100% of all three colors (CMY) together and you produce black. The process is subtractive and is commonly referred to as CMYK printing. A fourth color (blacK) is added to increase contrast and definition in photos and to create sharper text. Printing presses create full color images with light reflection using a slightly different three primary colors (Cyan, Magenta and Yellow). The absence of all three colors leaves black. In other words, add 100% of all three colors together and you produce white. Thousands of colors can be created from the three RGB primary colors (Red, Green and Blue). As files created in the RGB format would not look exactly as it looks like in the preparation software when printed with the CMYK format, it is advisable to convert these images or file to CMYK before sending for print.Ĭomputer monitors or television sets create full color images with light projection using three primary colors. All light mediums use the primary colors associated with light being Red, Green, Blue (Also known as RGB) The software used in the print industry also utilizes the RGB format of colors which are on a different spectrum then CMYK. Though the actual colors used are different, all printing, and in fact motion pictures and television, all depend on an analogous system of building a rainbow from only a few basic colors. That's all our optic hardware can deal with but our brain translates the optic information it receives into an entire rainbow of colors and hues. Light arrives in literally millions of colors, but our brains are organized to deal with only a few primary colors. The exact tint may require different percentages of each color to form the basic GREEN, and further enhanced by adding a small percentage of the other primary print colors. ![]() For example, to get a GREEN color from the four basic primary print colors, the industry utilizes CYAN and YELLOW that mix to give GREEN. This is the industry standard method of producing all color magazines, books, and other full color printed material. In print, the 4-Color Process, also known as CMYK (See above for how the acronym is derived from the basic colors).ĬMYK 4-color printing is capable of reproducing literally thousands of colors. Yellow ( Y) - a bright yellow color that lends brightness to the imageīlac K ( K) - a filler color that complements the image and gives it contrast. Magenta ( M) - a medium red color that lends warmth to the image These colors are as follows:Ĭyan ( C) - a light blue color that lends coolness to the image When the term "4 Color Process" is used, it means that the four primary printing colors are used. What is 4-color process printing? Do I only get 4 colors? The more absorbent it is, the more the colors will run, resulting in a muddy mess.Printing 101 Baby Steps To Print Purchasing Know How The Printing Crash Course - Printing School What is "4-color Process" Printing? The type of paper being used is also a factor. Getting that to happen accurately is difficult, as there is usually some smudging (not the correct term, I know). Some print machines print each color separately, so the background may be printed first, leaving space for the text to be printed next. You’ve also got to consider the difficultly of a background color with colored print over the top. Some really high-quality printers (for the really fancy print publications) can print very fine text accurately, but not all can. I had a stint a few years back using printers and this point was continually drilled into me.Īs for the OP’s other question about font sizes, it again depends on what kind of machines the printer uses, so ask them what’s too small for them. Each seems to have different requirements, depending on what kinds of machines they use, what sorts of things they print, and what kind of paper they use. I guess the thing to take away from this is to ask the printer what they require.
