TIFF (or TIF)

Stands for Tagged Image File Format and is the preferred file format used for bitmap images in the graphics industry. The best format to use when you don't want to lose quality in your image.

Tint

A percentage of a solid ink. Tints are created by using a screen to create the impression of a lighter colour when the ink is printed onto paper or another medium.

Tracking

The adjustment of the overall spacing between all text characters in a word or words. Tight means letters are close together, loose means letters are far apart.

Trapping

Is the implementation of small amounts of overlap on elements of a page's design to prevent conspicuous areas of whitespace from appearing on print jobs. To clarify let's look at an example. When a large blue title is printed on a red background, a hole (white space) is created in the red plate where the blue letter shapes will fall (otherwise the blue and red ink would mix resulting in a "purplish" blue). For one reason or another it can be very difficult for the printer to perfectly fit the blue shape into the red hole and unsightly white space can appear. For this reason a thin outline of blue is added to the edge of the letter shape that will overlap with the red image thus fixing the problem.

Typeface

The style and design of the letter forms in an alphabet.

Vector Image

A computer image that uses mathematical descriptions of paths and fills to define the graphic, as opposed to individual pixels. Can be scaled to any size without loss of quality.

WMF

Windows Metafile Format. Vector graphics format used in Microsoft products. Format of choice for Microsoft clip-art collections.

Work and Tumble

A method of printing where pages are again imposed together. The sheet is then printed on one side with the sheet being turned or tumbled from front to rear to print the opposite side.

Work and Turn

A method of printing where pages are imposed in one form or assembled on one film. One side is then printed and the sheet is then turned over sidewise and printed from the other edge using the same form or plate. The finished sheet is then cut to produce two complete copies.

X-height

The height of a letter excluding the ascenders and descenders. As an example, "x", which has neither ascender nor descender.
