|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.

One type of optical constant that describes the ability of a material to absorb light. The conversion of light or other electromagnetic radiation into heat energy. This light energy cannot be reflected back to an observer. The selective absorption of light is responsible for our perception of color. It is calculated during colorant set calibration, and is based on transmittance measurements.
Absorption coefficient (K)
An optical constant that quantifies the ability of a colorant to absorb light. Based on reflectance data for a sample, it is one of the values calculated during colorant set calibration, using the Kubelka-Munk equation. It is part of the data used to calculate color matches and corrections.
A subjective evaluation to determine whether a detectable color difference can be tolerated. Color differences may be measurable and perceptible, and still be tolerated.
One of six ingredient 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. An additive cannot be a colorant and does not have a strength factor. It can only exist as a component ingredient. Use additive for the ingredient type when the material does not fit any other category.
The affinity group is an optional field in textile formulation software that is used to group qualities with the same dyeing properties.
Appearance properties are attributes of a sample, other than color, that can affect both the instrumental measurement and the visual assessment of a colored sample. These properties include gloss, film thickness, opacity, and surface characteristics such as haze, roughness, etc.
Chemicals to be used for dyeing, finishing, etc. In pigment formulation, it is one of six ingredient types used by the program. It identifies a collection of ingredients sometimes worked with as a group, usually for purposes of formula scaling. An auxiliary cannot be a colorant and does not have a strength factor. It can only exist as a component ingredient. Use auxiliary for the ingredient type when the material does not fit any other category.
Mixture of transparent resins, solvents and/or additives necessary to make a colorant ready to use. Typically used in making up a sample for primary calibration.
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. Ingredients that you may need to scale or constrain as a group can be identified as a base. A base can be a colorant and has a strength factor attached to it. NOTE This ingredient type is largely reserved for the "autobase select" feature
Base (Trade Sales Paint)
A coating or paint mix which is a final product for use in a trade sales application. Bases are usually pastel (white), medium, deep, extra deep, transparent or colored. Bases are tinted with colorant dispersions (pastes) in laboratories, factories, or dealer locations.
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.
