Your Ink Glossary Terms Have Just Been Compiled In Order To Define The Content Of Your Cartridges

Absorption:

oThe dispersal and decreased transmission of visible light in its interaction with matter, resulting in the change 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 smooth 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 sufficient colour 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-colour process printing, black is one of the process inks. The letter "K" is used to represent black in the CMYK acronym to differentiate it from "B" for blue in RGB.

Brightness:

oThe measureMent of the reflective quality of a medium. Different brightness levels can cause changes in the appearance of color on the medium requiring adjustMents in calibration to achieve optimumresult.

Calibration:

oChecking, adjusting and standardizing the graduation of systematically to 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, the 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 institution concerned with color and color measureMent.

CMY:

subtractive primaries oThe cyan, magenta and yellow.
Color Calibration:

oCoordination of the color matching between two or more digital devices by means by hardware orsoftware.

Color Curve:

oVisual mechanism in Ph Meter:

oDevice that measures color values in relation to a specific set of standards, such as CIE. Enables measurement of differences in colors more precisely 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 measurement of the perceivable difference in a color by the human eye.

DensitoMeter:

oDevice used to measure the density of light by means of its absorption by a substrate or surface of paper or film. This is achieved either by reflection or transmission.

Density:

oThe ability of a material to absorb light. The darker the material, the higher the density.

Digital Printer:

oPrinting device 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 pixels groups instead of an ordered array of halftone dots. This reduces the contrast between dots of different colors or shades and yields a more flowing, natural impression.

Dot Gain:

oThe effect that is described when individual 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 number of separate pixels either horizontally or vertically represented in one square inch.

Dye:

oColored chemical that dissolves completely in water or other solvent; as opposed to pigments, which are insoluble.

Dye Sublimation:

oColorprinting technology that produces images by means of gaseous thermal printing dyes through to drivers.
Enhanced Color Gamut:

oWhen precisely diluted process colors cyan and magenta, usually, are used with CMYK to create more vibrant colors and a continuous-tone effect.

Expanded Color Gamut:

oWhen additional colors, usually green and orange, are printed with CMYK to match a greater number of colors than CMYK produced by Halo.

Fluorescent Lamp:

oA glass tube filled with mercury gas and whose inside surface is coated with Ph Meter (Nm):

oThe measurement of wavelengths. Unit of length equal to 109 Meters, or one millionth of a milliMeter.

Opacity:

oDescribes the resistance of light passing through a substrate.

Pantone Matching System (PMS):

oUnique numbering system for identifying colors created by combinations of SWOP standard inks.

Ph Meter:

oAn instrument that measures the characteristics of light that is either reflected from or transmitted through an object.

Spectrum:

oThe spatial arrangement of electromagnetic energy 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 approved reference against which instrument measurements are evaluated.

Subtractive primaries:

oCyan, magenta and yellow. The theoreticalcombination of the three at 100% strength should produce black on white paper. Their combination at varying intensities produces a gamute of colors. Combining two primaries at 100% creates either the red, green or blue additive primary.

Cyan + magenta = blue. Cyan + yellow = green. Magenta + yellow = red.

Surface Tension:

oThe forces of cohesion at the surface of a liquid which encourage the tendency of a liquid to reduce its exposed surface to the minimum area. Molecules within a liquid are attracted equally from all sides, but those near the surface experience 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 atemperatures 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 difference between the known correct standard 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 between 380 and 720 nanometers. Wavelengths within this span produces color as viewed by the human eye. Shorter wavelengths create violets, purples and blues, while longer wavelengths result in oranges and reds.

Wavelength:

oMeasurement of light as a component of electromagnetic waves. The wavelength is the peak-to-peak distancebetween 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.

These brief inkjet word definitions will help you with certain terms of vocabulary which settle on the plateau of ink.
