The PRINTING United Alliance Glossary of Terms serves as an excellent industry terminology resource. It is the language by which we all communicate, without it universal understanding would be impossible. Language and our ideas about how it is interpreted change rapidly. PRINTING United Alliance is aware of this and continues its effort to keep our constituents well informed about changes to the increasingly complex industry terminology. The definitions are for general reference only. Usage may vary between companies, individuals, or national and country customs. The information presented is as accurate as the authors and editors can ascertain and PRINTING United Alliance assumes no responsibility for the use of information presented herein.

The tackiness remaining in a film which, although set, does not reach the tack-free stage.
Ability to regain quickly an original shape after being strained or distorted.
(1) Any of a number of clear to translucent yellow or brown solid or semi-solid substances of plant origin as copal rosin and amber used in lacquer varnish ink, adhesive, and synthetic plastic; (2) in printing ink, the material that binds the pigment to the substrate.
A plate coating that hardens over the non-image areas after exposure to light; mixed with bichromated gum or other coating solution protects non-image areas during etching.
Resist printing (textile)
The printing of a resist agent on the cloth to prevent a printed ink from affecting a preselected protected area.
The opposition a material offers to direct current flow, measured in ohms.
The ratio of an applied voltage to the total current carried by a specific insulating material.
Resistance temperature characteristics
Relationship between thermistor resistance and the temperature it is sensing.
A device, material, or component that offers opposition to the flow of an electric current.
A thermosetting resin at the C-stage, or final stage of processing, where it becomes insoluble, or cured.
An uncured thermosetting resin at the B-stage, or intermediate stage of processing.
