|Knowledge Base - Glossary of Terms|
Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

The resin used to prepare the mixture samples in a colorant database set.
The substrate used to prepare the mixtures. The spectral values of the substrate are needed to calculate the optical constants for the materials included in the samples.
Calibration data (colorant or colorant set)
The calculation of optical constants for an individual colorant, or for an entire colorant set. The optical data for colorants can be calculated individually or simultaneously for an entire set. When an individual colorant has been calibrated and marked active, the colorant can be used for formulation and correction. When a colorant set is calibrated, the colorant set is available for formulation and correction. Depending on the application type, there are a minimum number of samples (types) that must be calibrated in the colorant set. For textile applications, it is concentrations of dyestuffs and a blank dyed Substrate which (when measured with the spectrophotometer) become part of the match prediction database in the form of colorant sets.
Measured sample dyed with defined concentration and dye strength. The data of the calibration samples is used for recipe calculation and correction. Calibration samples are used to calculate the calibration data (K/S) for each dyestuff used for recipe calculation and correction.
Can Fill Requirements
Short Fill, Full Fill, Over Fill and Correct Fill
This is one six ingredient type used by the pigment formulation program, and displays only when concentrate scaling is enabled in the software. It identifies the portion of resin that is mixed with the colorant to produce the concentrate, and remains in the concentrate. In effect, it "carries" the concentrate to the end user who will add more resin (the user-supplied resin). It may or may not be the same resin used in the finished product. The carrier resin is specified at run-time in pigment formulation, along with the user-supplied resin.
One of six ingredients types used by the pigment formulation program. It identifies a collection of ingredients sometimes worked with as a group, usually for purposes of formula scaling or restricting colorant load. It can be a colorant, but does not have a strength factor attached to it. The materials identified as "clears" are typically resins or extenders. All "clears" are assumed to have zero K and zero S, except for those used in translucent colorant sets.
A color is an ingredient typically used to impart color to a material. It can be a colorant and it has a strength factor. It is also one of the six (6) ingredient types used by the pigment formulation program, and identifies a collection of ingredients sometimes worked with as a group.
Magnitude and character of the difference between two colors located in a color space solid, or map, under specified conditions. The total color difference is generally designated as DE, the lightness difference as DL. In addition, differences are expressed along the redness-greenness axis, and the yellowness-blueness. Certain color difference calculations offer additional components to the color difference expression.
Color inconstancy is the color difference if a single sample is illuminated with different light sources. The magnitude of color inconstancy can be defined by DE CMC (or any other color difference formula) of the sample between two light sources.
The color index is produced jointly by SDC (Society of Dyers and Colourists) in the UK, and the AATCC (American Association of Textile Chemists and Colorists) in the USA. The index is split into two parts: one part gives the commercial names for the individual dyes; the other part of the index gives the color index number, and lists the commercial names for the dyes using that number. Refer to Color index number.
Color index number
Every dye is given a color index number based on its chemical type. The same number is given to the dyes with the same chemical structure. For example, Resolin Red FB and Dispersol Red B2B, both have the color index number “CI Disperse Red 60." The index number is divided into four sections: 1) CI stand for color index and is displayed in every color index number 2) The next section is the dye type, e.g., Disperse, Acid, etc. 3) The third section is the color, according to a defined list of color names, e.g., Red Yellow, Orange 4) The last number is increased every time a new dye is added to the index; in the example above, “CI Disperse Red 60" is the 60th red disperse dye to be added to the index. Refer to Color index.
Three-dimensional solid enclosing all possible colors. Colors are located in the solid through their calculated color coordinates. The distance between the samples in the color space solid is the color difference. The properties of the solid is transformed, though the application of various equations, i.e., giving rise to different calculations of the distance between the samples.
Measured color of a sample. The color type is the target color to be dyed.
A set of optical constants, and the data used to generate those optical constants. This data includes the optical model, mixture grouping type, colorant concentrations, density, curve smoothing method, instrument geometry, measurement type, and other data used to calculate the optical constants. A coloring matter; a dye, a pigment or an ink.
