HKS (colour system)
The HKS color contains 88 so-called basic colors and a total of 3,520 solid colors for coated and uncoated paper, the meaning of the objective (ie independent of the individual color perception) Bewert and comparability, reproducibility and communication of certain shades of color in the graphic arts industry. HKS is, first, the abbreviation for the pressure and Artists Paint Manufacturers host man -Steinberg inks, Kast Ehinger inks and H. Schmincke & Co. and secondly their trademark or brand.
Use
Each HKS color can, for example, be reproduced by using a HKS industrial premixed or the mixed pigments from the printer HKS spot color offset printing. Alternatively, their color effect (usually only approximately ) by the mix of the four- color printing cyan, magenta, yellow and black (CMYK ) are simulated.
Paper effect
There are various HKS color that are the different color reproduction depending on the substrate used meet:
- HKS K (coated paper)
- HKS N (uncoated paper)
- HKS Z ( newsprint)
- HKS E ( continuous paper )
Color matching
The so-called Color Matching ( color matching, instead of the original next- the technically similar color is used) is a typical application that uses the HKS color. For example corresponds HKS 47 K the cyan of the CMYK scale, while HKS 47 Z is slightly more blue than cyan. In the print result is that, due to the adaptation to different substrates, the same color perception can be achieved.
If you want to HKS - colors to use as a basis for other media in which no special colors can be used / are, they can based on their L * a * b * values to be converted. However, the HKS color of the substrate matching fan must be used absolutely. These conversions can set the professional desktop publishing and graphics software itself. Appear also regularly updated at HKS color management software enhancements for accurate color matching, assessment and application of HKS - colors. In addition, there are printing, the HKS - colors in CMYK pictures ( on different substrates ) and creative people to facilitate the work.
While there is the net countless pages, the RGB values for HKS - colors list, of but their use is not recommended because the RGB values are different depending on the RGB color profile used - there are basically not the RGB value for a HKS - or other ink.
