HKS colours, similar to Pantone colours, can be used in any kind of print publication to produce predictable colours. As in the Pantone colour system, there are HKS colours that cannot be reproduced using the CMYK color model color space, like bright orange or certain tones of blue. The HKS colour system is based on the euroscale colourspace.
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: cyan, magenta, yellow, and key (most often black).
The two additional spot colors are added to compensate for the ineffective reproduction of faint tints using CMYK colors only. However, offset technicians around the world use the term spot color to mean any color generated by a non-standard offset ink; such as metallic , fluorescent , or custom hand-mixed inks.
Pantone LLC (stylized as PANTONE) is an American limited liability company headquartered in Carlstadt, New Jersey, [1] and best known for its Pantone Matching System (PMS), a proprietary color order system used in a variety of industries, notably graphic design, fashion design, product design, printing, and manufacturing and supporting the management of color from design to production, in ...
CMYK is used in the printing process, because it describes what kinds of inks are needed 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.
A color space may be arbitrary, i.e. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names (including discrete numbers in – for example – the Pantone collection), or structured with mathematical rigor (as with the NCS System, Adobe RGB and sRGB). A "color space" is a useful ...
It was designed to encompass most of the colors achievable on CMYK color printers, but by using RGB primary colors on a device such as a computer display. The Adobe RGB (1998) color space encompasses roughly 30% of the visible colors specified by the CIELAB color space – improving upon the gamut of the sRGB color space, primarily in cyan ...
The CMYK model adds a black primary to improve the darkness of blacks, where the CMY model can only mix to dark gray or only achieves black inefficiently, i.e. by using lots of the primary pigments. In the CMY model, an equal mixture of cyan and magenta is blue , an equal mixture of magenta and yellow is red and an equal mixture of yellow and ...
