"Four Color Four Color, also known as Four Color Comics and One Shots, was an American comic book anthology series published by Dell Comics between 1939 and 1962. The title is a reference to the four basic colors used when printing comic books (cyan, magenta, yellow and black at the time). More than 1,000 issues were published, usually with multiple titles released every month. An exact accounting of the actual number of unique issues produced is difficult because occasional issue numbers were skipped and a number of reprint issues were also included. Nonetheless, the ""Overstreet Comic Book Price Guide"" lists"
"CMYK color model The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and black. The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ""subtractive"" because inks ""subtract"" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green"
"newspapers and magazines, brochures, cards, posters and similar mass-market items. In this type of industrial or commercial printing, the technique used to print full-color images, such as color photographs, is referred to as four-color-process or merely process printing. Four inks are used: three secondary colors plus black. These ink colors are cyan, magenta, yellow and key (black); abbreviated as CMYK. Cyan can be thought of as minus-red, magenta as minus-green, and yellow as minus-blue. These inks are semi-transparent or translucent. Where two such inks overlap on the paper due to sequential printing impressions, a primary color is perceived. For example,"
"CcMmYK color model CcMmYK, sometimes referred to as CMYKLcLm or CMYKcm, is a six color printing process used in some inkjet printers optimized for photo printing. It complements the more common four color CMYK process, which stands for Cyan, Magenta, Yellow and Key (black), by adding light cyan and light magenta. Individually, light cyan is often abbreviated to Lc or c, and light magenta is represented as Lm or m. The most noticeable result of using light cyan and light magenta inks is the removal of a distinct and harsh halftoning dot appearance that appears in prints that use light"
"defining the CMY primaries as substances that ""absorbed"" only one of the retinal primary colors: cyan absorbs only red (−R+G+B), magenta only green (+R−G+B), and yellow only blue violet (+R+G−B). It is important to add that the CMYK, or process, color printing is meant as an economical way of producing a wide range of colors for printing, but is deficient in reproducing certain colors, notably orange and slightly deficient in reproducing purples. A wider range of color can be obtained with the addition of other colors to the printing process, such as in Pantone's Hexachrome printing ink system (six colors),"
"color variance occurs when there are changes to the specific paper stock used. The Pantone Color Matching System is largely a standardized color reproduction system. By standardizing the colors, different manufacturers in different locations can all refer to the Pantone system to make sure colors match without direct contact with one another. One such use is standardizing colors in the CMYK process. The CMYK process is a method of printing color by using four inks—cyan, magenta, yellow, and black. A majority of the world's printed material is produced using the CMYK process, and there is a special subset of Pantone"
"Spot color In offset printing, a spot color or solid color is any color generated by an ink (pure or mixed) that is printed using a ""single run"", whereas a process color is produced by printing a series of dots of different colors. The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key (black) commonly referred to as CMYK. More advanced processes involve the use of six spot colors (hexachromatic process), which add orange and green to the process (termed CMYKOG). The two additional spot colors are added to compensate for the ineffective reproduction"

As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips. Process magenta is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure magenta ink.

It is primarily used in art and design education, particularly painting.

"because it is a color commonly associated with water, such as the appearance of the water at a tropical beach. Cyan is also one of the common inks used in four-color printing, along with magenta, yellow, and black; this set of colors is referred to as CMYK as in spectrum(s). While both the additive secondary and the subtractive primary are called ""cyan"", they can be substantially different from one another. Cyan printing ink can be more saturated or less saturated than the RGB secondary cyan, depending on what RGB color space and ink are considered. Process cyan is not an"
"Registration black In CMYK printing, registration black refers to 100% coverage in each of the four process colors: cyan (C), magenta (M), yellow (Y), and black (K). More generally, if a different mixture of colors is being used, registration black marks in each of the colorants (inks) used. It is therefore not correct to simply define registration color as 100% of C,M,Y,K, since it will rather be 100% of whichever colors are used in reproduction. It is a special purpose color, and as such is not generally used to print black text or grayscale graphics. Instead, registration black is used"
"spot colors (such as metallic inks), and finishes such as varnish, which enhances the glossy appearance of the printed piece. CMYK are the process printers which often have a relatively small color gamut. Processes such as Pantone's proprietary six-color (CMYKOG) Hexachrome considerably expand the gamut. Light, saturated colors often cannot be created with CMYK, and light colors in general may make visible the halftone pattern. Using a CcMmYK process, with the addition of light cyan and magenta inks to CMYK, can solve these problems, and such a process is used by many inkjet printers, including desktop models. Comparisons between RGB"
"(9 o'clock is zero degrees). Halftoning is also commonly used for printing color pictures. The general idea is the same, by varying the density of the four secondary printing colors, cyan, magenta, yellow and black (abbreviation CMYK), any particular shade can be reproduced. In this case there is an additional problem that can occur. In the simple case, one could create a halftone using the same techniques used for printing shades of grey, but in this case the different printing colors have to remain physically close to each other to fool the eye into thinking they are a single color."
"and ink in use. Processes called under color removal, under color addition, and gray component replacement are used to decide on the final mix; different CMYK recipes will be used depending on the printing task. CMYK or process color printing is contrasted with spot color printing, in which specific colored inks are used to generate the colors appearing on paper. Some printing presses are capable of printing with both four-color process inks and additional spot color inks at the same time. High-quality printed materials, such as marketing brochures and books, often include photographs requiring process-color printing, other graphic effects requiring"
"versatile CMY (Cyan, Magenta, Yellow) triad had been adopted, with the cyan sometimes referred to as ""process blue"" and the magenta as ""process red"". In color printing, the usual primary colors are cyan, magenta and yellow (CMY). Cyan is the complement of red, meaning that the cyan serves as a filter that absorbs red. The amount of cyan applied to a white sheet of paper controls how much of the red in white light will be reflected back from the paper. Ideally, the cyan is completely transparent to green and blue light and has no effect on those parts of"
"of the primaries: cyan and yellow produce green, cyan and magenta produce blue, yellow and magenta produce red (these subtractive secondary colors correspond roughly to the additive primary colors), plus layering all three of them resulting in black. With halftoning, a full continuous range of colors can be produced. To improve print quality and reduce moiré patterns, the screen for each color is set at a different angle. While the angles depend on how many colors are used and the preference of the press operator, typical CMYK process printing uses any of the following screen angles: The ""black"" generated by"

"mixing commercially practical cyan, magenta, and yellow inks is unsatisfactory, so four-color printing uses black ink in addition to the subtractive primaries. Common reasons for using black ink include: When a very dark area is desirable, a colored or gray CMY ""bedding"" is applied first, then a full black layer is applied on top, making a rich, deep black; this is called ""rich black"". A black made with just CMY inks is sometimes called a ""composite black"". The amount of black to use to replace amounts of the other ink is variable, and the choice depends on the technology, paper"
"dyes, paints and inks. It also created the dyes and chemical processes necessary for color photography. As a result, three-color printing became aesthetically and economically feasible in mass printed media, and the artists' color theory was adapted to primary colors most effective in inks or photographic dyes: cyan, magenta, and yellow (CMY). (In printing, dark colors are supplemented by a black ink, known as the CMYK system; in both printing and photography, white is provided by the color of the paper.) These CMY primary colors were reconciled with the RGB primaries, and subtractive color mixing with additive color mixing, by"

As computer and software technology has advanced, and the cost reduced, many clubs are now in a position to print their own maps. This enables clubs to print the six colours together (map and overprinting symbols) using that same four-colour process, but with a reduction in quality over traditional printing. Printing costs can be minimised by using standard stock sizes of paper e.g. A4 or Letter. It is important to use the correct type of paper: both the weight and"

Software companies that used Hexachrome include Aldus (now Adobe), Adobe Photoshop, and QuarkXPress; as well as the printer manufacturers HP, Epson, and Xerox. Hexachrome Hexachrome is a discontinued six-color printing process designed by Pantone Inc. In addition to custom CMYK inks, Hexachrome uses orange and green inks to expand the color gamut for better color reproduction. It is therefore also known as a CMYKOG process. Hexachrome was discontinued by Pantone in 2008 when Adobe Systems stopped supporting the HexWare plugin software. While the details of Hexachrome were not secret, its use was limited"

Color printing, like painting, also uses subtractive colors, but the complementary colors are different from those used in painting. As a result, the same logic applies as to colors produced by light. Color printing uses the CMYK color model, making colors by overprinting cyan, magenta, yellow, and black ink. In printing the most common complementary colors are magenta–green, yellow–blue, and cyan–red. In terms of complementary/opposite colors, this model gives exactly the same result as using the RGB model. Black is added when needed to make the colors darker. The"

CMYK uses subtractive color mixing used in the printing process, because it describes what kind of inks need to be applied so the light ""reflected"" from the substrate and through the inks produces a given color. One starts with a white substrate (canvas, page, etc.), and uses ink to subtract color from white to create an image. CMYK stores ink values for cyan, magenta, yellow and black. There are many CMYK color spaces for different sets of inks, substrates, and press"

The red-filtered image is used to create a cyan dye image, the green-filtered image to create a magenta dye image, and the blue-filtered image to create a yellow dye image. When the three dye images are superimposed they form a complete color image. This is also known as the CMYK color model. The ""K"" is a black component normally added in ink-jet and other mechanical printing processes to compensate for the imperfections of the colored inks used, which ideally should absorb or transmit"

"displays and CMYK prints can be difficult, since the color reproduction technologies and properties are very different. A computer monitor mixes shades of red, green, and blue light to create color pictures. A CMYK printer instead uses light-absorbing cyan, magenta, and yellow inks, whose colors are mixed using dithering, halftoning, or some other optical technique. Similar to monitors, the inks used in printing produce a color gamut that is ""only a subset of the visible spectrum"" although both color modes have their own specific ranges. As a result of this, items which are displayed on a computer monitor may not"
"Under color removal In printing, under color removal (UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and replacing them with black ink only, called a ""Full Black"", during the color separation process. Under color removal is used in four-color (or more colors) printing. Black ink used to add details and darkness in shadowed areas is called a ""Skeletal Black"". With current ink technology, the total CMYK ink in the shadows refuses to stick after it reaches the dark shadows (usually above a 250% total CMYK coverage), and begins"
