EVV Print Graphics Glossary

The distance from the edge of the paper to the image area occupied by text and/or graphics.

See transfer tape.

An analog or digital image used to eliminate unwanted portions of an image. An analog mask could consist of a negative film, hand cut ruby or amber film or simply photographically opaque paper. Digital mask files utilize a clipping path and are superimposed over an image to define which portions of the image should print and which should not. Image pixels inside the clipping path print; pixels outside the clipping path do not. A similar mask can be used to control the area of a graphic affected by such operations as colour correction, filters, tool effects, etc.

A low gloss finish. This can be achieved by printing directly to a matte substrate or by laminating a print with a matte film. This finish is best suited for indoor applications as less light is reflected off the surface creating ‘hot spots’.

The materials to be printed on. It can be anything from bond paper to copper and wood vellum.

Approximately one million bytes. Commonly written as MB and spoken as a “meg”.

A proof used to ensure the correct page numbers, orientation, and dimensions are used in the final printout of an imposition layout. A good mockup is as close as possible to the finished product, and is of great value in showing trimming, folding and assembling in pieces involving complicated finishing operations, such as boxes.

Interference caused by incorrect halftone screen angles which results in an undesirable pattern in multi-colour printing. Images such as plaid or checkered fabrics can also interfere with the angles of the halftone screens. One advantage of stochastic screening is the reduction of obvious and subtle moirè patterns.

The colour attributes of an image made up of one or more tones of one hue.
