nuance
nuance (In French nuance) chromaticity coordinates; comprehensive designation for a color perception combining the attributes hue, brightness and chromaticness.

NPDC, G7-NPDC see GRACoL
normal inking (In French encrage normal) the inking in halftone printing at which the highest possible chromatic saturation with the best possible differentiation of the half tones vis-à-vis the solid tone; precondition for maximum printing contrast.
neutral point, origo, illuminant locus (In French point neutre/achromatique) white point of an illuminant (on the monitor as well), also paper white when illuminating a white paper surface.
neutral (In French neutre) designation of a gray absolutely free from any color cast.
Neugebauer equations (In French équations de Neugebauer) mathematical description attempt by Hans E.J. published between 1935 and 1949 of the autotypical color blending of the four process colors with each other and with paper white as well as of the conditions for the production of color separation files/prints (filters, color correction, spectral sensitization of the film material).
NCS, Natural Color Systemcolor ordering system published by A. Haard in 1972 as a Swedish standard; is also accepted, with restriction, in Germany parallel to DIN 6164; the parameters are blackness s, whiteness w and chromaticness c in 100 stages each as well as hue ö in 400 stages, which every 100 stages show one of the 4 elementary hues original red, original blue, original green and original yellow; not compatible with CIELAB.
Munsell Book of Color (In French Atlas/nuancier colorimétrique de Munsell) color ordering system common in the USA and the UK (Munsell scale, 1915/1929); today 1500 matt and 1300 glossy nuances of color; each of the 40 plates into which the color sample is pushed in tabs contains nuances of a hue (Munsell Hue, Mn. H), which differ vertically in their brightness (Munsell Value, Mn. V 0 to 10) and horizontally in their chromaticness (Munsell Chroma,…
multicolor printing impression (In French polychrome/en plusieurs couleurs) printing process with four and more separation colors.
monochrome, black and white (In French achrome, noir et blanc) property of pixel graphics files that have only one grayscale channel (brightness, “black and white”); if the file in question is a TIFF file, it is possible to recolor the image file when it is being output.
monochromator, spectral analyzer (In French monochromateur) component in every spectrophotometer/spectrodensitometer which divides up the luminous flux of the measured light into its chromatic intensity components; 2 construction types: lattice (dispersion through diffraction, e.g. Techkon scanning head), prism (dispersion through refraction; disadvantage: greater weakening losses)
monochromatic (In French monochromatique) property of light sources that emit only one single wavelength (e.g. laser, sodium-vapor lamp).
monitoring of quality (In French surveillance de la qualité) permanent systematic recording (protocoling), observing and monitoring of devices and processes using technical aids. The real-time and long-term monitoring of the calibration status of all process components as an image of the true and not only simulated quality level is a selection criterion that is becoming more and more important for quality-oriented purchasers of printed matter. The Internet-based solution iQIP by impakt medien offers comprehensive and…
moisture-set, steam-set: long grain rotary printing process (letterset, offset) with printing inks which harden through the effect of water vapor, but which remain printable at normal humidity or which do not soften after film formation; application: folding box production for foodstuffs in America and China.
Mired, micro-reciprocal degree “Millionth reciprocal degree” of the Kelvin numerical system value of the most similar color temperatures of light sources, calculated from the hundred thousandth reciprocal of the Kelvin system; for CIE standard illuminant D50, this means: 1000000 / 5000 K = 200 Mired – see Table C-2 “Color temperature” on page 32.
migration (In French migration) transition of molecular components on the one hand from the printing ink into the packaging material (desired) and possibly into the package contents (undesired), on the other hand from the package contents into the packaging material (undesired) or even into the printing ink layer (undesired); remedies: low-migration printing inks, trueness vis-à-vis packaging materials, barriers in the packaging matemigration rial, avoid migration through set-off in piles and through contact with pressroom chemicals…
Microsoft ICM2-WCS, Image Color Management v2 – >Windows Color System color management architecture introduced gradually by Microsoft (Longhorn) and Canon (Kuyanos CMM) (Color Infrastructure and Translation Engine, CITE), which can process ICC v4 profilers in the formats .icc and .icm. Always proceeding from the sRGB working color space (sRGBColorSpaceProfile.icm), it uses the various XML profile schemes (described as “display conditions” in the German Windows version): – generic device groups (Color Device Model Profiles, .cdmp) with…
metamerism (In French métamérisme) conditional equality of colors; effect according to which two or more samples happen to look the same under a reference illuminant and which differ in color, after the change in illuminant on account of their spectral composition. The metamerism index, which can be illustrated with a spectrodensitometer, e.g. Techkon SpectroDens, through two individual measurements, is specified using the CIELAB color difference formula in ΔE*ab for D50 vis-à-vis D65. All illuminant pairs…
metallic inks (In French encres métalliques) printing inks to which metallic pigments have been added to achieve a metallic gloss effect. Such pigments are brass-based “rich gold”, “rich pale gold”, “pale gold”, “copper” as well as aluminium-based for gold an poor aluminium for silver. Besides gold and silver printing inks, Pantone metallic hues are also on offer.
metal decorating inks (In French encres pour impression sur métal) sheet-fed offset inks used for printing metal plates up to 0.5 mm thickness; drying mechanism either radical UV-curing (basis: acrylates) or solvent evaporating-burning in (basis: oil-based alkyds or other modified polyesters); KBA-MetalPrint is the only supplier of metal printing systems up to 8 colors.
