|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.

Descriptive of a match that is commercially unacceptable.
A general term used to describe the degree to which a material obscures a substrate. It is the opposite of ‘translucency’, the degree to which a material does not obscure a substrate. Opacity and/or translucency are measured in terms of a contrast ratio.
Adjective used to describe complete opacity.
In textile formulation software, the operation specifies the sequence of action to be done during the dyeing. Actions may be parameters (e.g., temperature, volume,)or products (e.g., chemicals, etc.).
An ingredient that fluoresces. When this happens, the ingredient absorbs light at a specific wavelength in the ultra violet range of the spectrum, and re-emits it at a wavelength in the visible spectrum. The energy is usually re-emitted at the shorter wavelengths of the visible spectrum (i.e., in the blue region of the visible spectrum), and the resulting effect is that the material displays brighter, bluer, or ‘whiter than white’. Also referred to as a fluorescent agent or fluorescent brightener.
Also referred to as optical data / optical properties. A numerical description of the way an ingredient interacts with light. Optical data is typically generated for colorants, but may also be calculated for other ingredient types such as resins, depending on the ingredient composition. Optical data can be expressed using the following terms: • K(absorption) and S(scattering)values • K/S values • A(absorbance) The same colorant used in different product lines may generate different optical data.
In pigment formulation software, it is the mathematical approach used to calculate the K (absorption) and S (scattering), K/S values or A (absorbance) values for colorants. There are four models to choose from: • Transparent • Transmission • Translucent • Opaque Each type uses a specific method for sample preparation and sample presentation, and a specific mathematical equation for calculating the optical constants.
Process by which the program calculates optical constants through a curve fit between the sum of the level data and the sum of the mixtures data.
