Many newspapers use 133-line screens, as do some magazines. Newspaper people are in a hurry to get their product out, and can't wait for ink to dry. Magazine paper is high quality, so that the ink can dry by oxydation, which takes longer. Techie Note: Low-quality screens are necessary for newspapers because the ink needs to blot into the paper to dry quickly, therefore producing the muddy look called dot gain.

A 65-line screen, for example, is 65 dpi, quality good enough for newsprint reproduction, but not for high-quality magazine reproduction. Halftone quality corresponds to computer monitor quality based on the number of dots of ink per inch, or dpi. Yes, it's a complicated process, and that's why good color printing demands skilled technicians in the back shop. In color reproduction, the dots overlap to act as tiny filters on the white page to produce combinations of colors. The closer these dots are to each other, and darker the color-also the principle of black-and-white reproduction, which uses only one ink, black. To produce all colors then, color pictures have to be broken into tiny dots, called the halftone process. In fact, most process color uses only four translucent inks. Note that printers are constrained as web and television producers are not-printers cannot adjust ink levels to such an extent. For example, cyan + magenta filters first the red, then the green, to produce blue (illustration at right).Д¬yan + magenta+yellow=muddy brown, hence the need for black ink. Again, we can combine two of these subtractive colors to produce the additive. Cyan (blue-green), magenta (red-blue) and yellow (red-green) inks are used along with black ('K,' meaning Key color) to filter reflected white from the paper and produce all colors. This is the principle of subtractive color, or CMYK color, the 'process-color process' used by printers. That area appears red because the marker is absorbing blue and green from the white reflection of the paper, but it can't absorb red, so it transmits that. All sunlight is reflected from it, so the paper appears white. Picture a piece of white paper in sunlight. Keep in mind white is all light together (think of your prism experiment from grade school), meaning that ink or paint subtracts from that white to produce the colors you see. This is because color reflected from a surface begins with white, or a light color. Printers and anyone working with color on paper or another reflective surface can't work with additive primaries. Red + green + blue=white, the whole spectrum. Note that if you project the additive primaries, say, from a spotlight onto a stage, a combination of two will produce a subtractive primary (illustration at right). Multiple 255 times 255 times 255 and how many color combinations do you get? More than 16.7 million, presuming your monitor is capable of showing that many (most modern monitors are capable of this 24-bit, or 'true color'). Other colors correspond to a specific voltage combination. Obviously, 0, 0, and 0 will produce black, or absence of color, and 255, 255 and 255 will produce white.

These produce color intensity based on a voltage level, from 0 to 255.

This principle generates color for televisions, computer monitors and movie screens, that is, all projected color.Д¬olor on television and monitors is produced by three color 'guns' corresponding to each additive primary. The three colors are projected onto a screen in various intensities to produce all colors. The additive primaries red green and blue generate color by beginning with absence of color, black, to generate all colors. A fourth 'primary,' black, is used for printed color. Modern color theory is based on three primary colors, projected colors red green and blue, or its printed complements, cyan, magenta, and yellow (that's yellow, hard to read on a white background, no?).
