Gloss Meter: An instrument utilized to measure the specular (mirror) reflectance from the surface at a specified angle.
Fog: In images, silver density within the non-impression regions. Alt: A defect in a print or negative made up of a deposit of silver extraneous on the intended picture. Fog may be caused by poor acquiring, or by light-weight leaks in the darkroom
Dot development: The enlargement of a halftone dot with the printing plate for the printed picture as a result of tension required to transfer the ink on to the substrate.
Extrusion coating: A approach whereby paper inventory is coated by extrusion, normally plastic such as polyethylene; extrusion laminating.
Digital color proof: An off-press shade evidence produced from digital details without the necessity for separation films.
Cast Film: The fabrication of the film by continually pumping the polymer by way of a straight slot die, then chilling this warm plastic promptly as a result of contacts with a chilled roll. Film width is decided by how briskly the chill roll pulls the film from the die.
