If you need some help with ink and printing terms, this section will help you. The following glossary should help you grasp the leading concepts that control the art and science of ink usage.
Absorption:
Piezo Electric
oThe dispersal and decreased transmission of illustrated light in its interaction with matter, resulting in the convert of its color.
Appearance:
oThe nature of objects as visual attributes, such as size, shape, color, texture, glossiness, transparency and opacity.
Attribute:
oColors are often described by their attributes of hue, saturation or chroma, and lightness.
Banding:
oDistinct pattern alterations, rather than a plane transition of colors or other effects in a gradient. Occurs in continuous tone images when displayed using less than 24 bits of digital information or if printing gradients without enough color information.
Black:
oThe absence of reflected light; the color that is produced when an object absorbs all wavelengths from the light source. When 100% of cyan, magenta and yellow are combined, the resultant color should be black, but in reality produces a muddy gray or brown. Therefore in four-color process printing, black is one of the process inks. The letter "K" is used to characterize black in the Cmyk acronym to differentiate it from "B" for blue in Rgb.
Brightness:
oThe estimation of the reflective potential of a medium. Separate glow levels can cause changes in the appearance of color on the medium requiring adjustments in calibration to accomplish optimum result.
Calibration:
oChecking, adjusting and systematically standardizing the graduations of a device.
Chroma:
oIn visual perception, when an area appears saturated with a particular color or hue. For example, a red apple is high in chroma; pastel colors are low. Black, white and gray have no chroma. Part of the color model, L*C*H or lightness, chroma, hue. Also referred to as saturation.
Cie:
oCommission International de l'Eclairage or the International Commission on Illumination, which is the main world convention concerned with color and color measurement.
Cmy:
oThe subtractive primaries cyan, magenta and yellow.
Color Calibration:
oCoordination of the color matching in the middle of two or more digital devices by means by hardware or software.
Color Curve:
oVisual mechanism in photo and graphics software to display color measurements and make tonal changes in an image.
Color Separation:
oPhotographic or electronic process for creating patterns of plates for each component of a color space. In printing, for example, separating the cyan, magenta, yellow and black components of a page image.
Color Wheel:
oAn arrangement of the illustrated spectrum's continuum of colors in a circle fashion, that has complementary colors, such as red and green, placed opposite from each other.
Colorants:
oMaterials used to generate colors, such as dyes, pigments, toners and phosphors.
Colorimeter:
oDevice that measures color values in relation to a exact set of standards, such as Cie. Enables estimation of differences in colors more categorically than the human eye.
Cyan:
oThe "redless" process color. It absorbs all red wavelengths and reflects all blue and green wavelengths of light.
Delta-E:
oUnit of estimation of the perceivable discrepancy in a color by the human eye.
Densitometer:
oDevice used to portion the density of light by means of its absorption by a substrate or surface of paper or film. This is achieved whether by reflection or transmission.
Density:
oThe potential of a material to suck in light. The darker the material, the higher the density.
Digital Printer:
oPrinting expedient that translates digital data into hard copy output.
Dithering:
oA process that simulates shades of gray or color variations by differing sizes and shapes of pixel groups instead of an ordered array of halftone dots. This reduces the discrepancy in the middle of dots of Separate colors or shades and yields a more flowing, natural impression.
Dot Gain:
oThe consequent that is described when personel dots in a halftone screen or other such patterns print out larger than their intended size, resulting in a darkening of the image.
Dots per Inch (Dpi):
oMeasurement that describes the resolution of image files by measuring the amount of cut off pixels represented whether horizontally or vertically in one quadrate inch.

oColored chemical that dissolves completely in water or other solvent; as opposed to pigments, which are insoluble.
Dye Sublimation:
oColor printing technology that produces images by means of gaseous dyes through a thermal printing driver.
Enhanced Gamut Color:
oWhen categorically diluted process colors, commonly cyan and magenta, are used with Cmyk to generate more vibrant colors and a continuous-tone effect.
Expanded Gamut Color:
oWhen supplementary colors, commonly green and orange, are printed with Cmyk to match a greater amount of colors than produced by Cmyk alone.
Fluorescent Lamp:
oA glass tube filled with mercury gas and whose inside surface is coated with phosphors. Once the gas is charged with electrical current, radiation is produced which then energizes the phosphors and causes them to glow.
Four-Color Process:
oPrinting or other imaging with combinations of the subtractive primaries of cyan, magenta, yellow and black. These are deposited as dots of Separate sizes, shapes and angles to generate the illusion of Separate colors.
Gamut:
oThe range of colors that can be interpreted by a color model or generated by a exact device.
Gamut Compression:
oAlso known as tonal-range compression. The coordinates of a color space with a larger gamut are reduced to comply with the smaller gamut of a destination color space. For example, the gamut of photographic film is compressed for representation in the smaller Cmyk gamut in four-color process printing.
Gradation:
oThe transition in the middle of two colors or in the middle of black and no color which is created by mixing percentages of the dominant and secondary color and then alternating them to produce the desired effect.

Hue:
oThe basic color of an object as defined by its angular position in a cylindrical color space, or on a Color Wheel.
Inkjet:
oPrinting process where liquid ink is propelled at a substrate, such as paper or film, to form characters and graphics. There are three kinds of inkjet printing: thermal, piezoelectric and phase change.
Intensity:
oSaturation, or reflective light, in relation to illustrated wavelengths of light. The reflectance of wavelengths at high intensity generates high saturation or chroma.
Light:
oElectromagnetic radiation in the spectral range that is detectable by the human eye (approximately 380 to 720 nm).
Light Magenta/Light Cyan (Lm-Lc):
oMuted or diluted forms of the two traditional colors. When added to Cmyk these shades produce more range in dot color and natural continuous tone printing.
Lightness:
oThe attribute that makes an area emit or reflect more or less light. Also refers to the perception by which white objects are suited from gray, and light from dark objects.
Luminance:
oDescribes the glow of an image.
Magenta:
oThe "greenless" process color. It absorbs all wavelengths of green from light, while reflecting all red and blue wavelengths.

Pixels per Inch (Ppi):
oThe amount of pixels in a rastar image that occur in one line along one inch. The greater the pixels, the higher the resolution.
Primary Color:
oColors that are the bases for other colors. In light, the traditional colors are red, green and blue (Rgb). In color photographic printing, they are cyan, magenta and yellow (Cmy). Black or key (K) is added as a fourth ink to Cmy printing to produce denser, truer blacks and clearer, sharper images.
Print On Demand:
oTerm for a range of short-run publishing processes that include copier technologies and direct-to-press applications.
Prism:
oTriangular-shaped glass or other transparent material through which, when light is passed, its wavelengths refract into a rainbow of colors. A demonstration that light is composed of colors and indication of the arrangement of colors in the illustrated spectrum.
Process Color:
oCyan, magenta, yellow and black combined to generate a new color.
Raster Image Processor (Rip):
oSoftware and/or hardware used to convert digital printing to information needed by a printer or other expedient to produce finished output. This operation is commonly called "ripping" (a file).

Spectral Curve:
oA visual representation of a color's spectral data as the color's "fingerprint". A spectral curve is plotted on a grid comprised of a vertical axis of the level of reflectance intensity, and a horizontal axis describing the illustrated spectrum of wavelengths. The division of reflected light at each interval is plotted as points on a curve.
Spectral Data:
oThe most exact description of the color of an object. Since an object's color appearance results from light being changed by it and reflected to the viewer, spectral data describes how that reflected light was changed. The division of reflected light is measured at some intervals over its spectrum of wavelengths, which is then visually represented as a spectral curve.
Spectrophotometer:
oAn instrument that measures the characteristics of light that is whether reflected from or transmitted through an object.

oThe spatial arrangement of electromagnetic vigor in accordance to size of wavelength.
Spooler:
oThe space where printing data is held in a computer's memory or hard drive while queuing to a printing device.
Specifications for Web Offset Printing (Swop):
oFormulations for inks used in web offset presses.
Standard:
oAn established and stylish reference against which instrument measurements are evaluated.
Subtractive primaries:
oCyan, magenta and yellow. The theoretical mixture of the three at 100% strength should produce black on white paper. Their mixture at varying intensities produces a gamute of colors. Combining two primaries at 100% creates whether the red, green or blue additive primary.
Cyan+magenta=blue. Cyan+yellow=green. Magenta+yellow=red.
Surface Tension:
oThe troops of cohesion at the surface of a liquid which encourage the tendency of a liquid to cut its exposed surface to the minimum area. Molecules within a liquid are attracted equally from all sides, but those near the surface touch unequal attractions and are thus drawn towards the center of the liquid mass by this net force.
Thermal Drop-on-Demand:
oInkjet printing process where inks are heated in a chamber above the print head to a temperature greater than their boiling point. The heat alters and expands the characteristics of the ink, which is then expelled through the head onto the substrate.
Tolerance:
oThe acceptable discrepancy in the middle of the known exact acceptable and a set of measured samples. See Delta Error.
Viscosity:
oThe internal resistance to flow exhibited by a fluid.
Visible Spectrum:
oThe region in the electromagnetic spectrum in the middle of 380 and 720 nanometers. Wavelengths within this span produce color as viewed by the human eye. Shorter wavelengths generate violets, purples and blues, while longer wavelengths consequent in oranges and reds.
Wavelength:
oMeasurement of light as a component of electromagnetic waves. The wavelength is the peak-to-peak distance in the middle of two adjacent waves.
Yellow:
oPure yellow is the "blueless" color. It absorbs all wavelengths of blue from light, and reflects all red and green wavelengths.
