In typesetting, tables and charts with columns of data must be aligned.

TAC

Abbreviation for Total Area Coverage: the total build-up of ink on a given spot on the paper. An area where 70 percent cyan is combined with 50 percent yellow and 20 percent black has a TAC of 140. This site has a page with more information on TAC or TIC (Total Ink Coverage, as it is sometimes also called).

tack

The ‘stickiness’ or adhesive quality of ink while printing.

tag

– A dense, strong paper stock.
– In page composition systems, a notation that defines each classification of text in a publication, such as the title, subtitles and body text. Typographic styles can then be assigned to each tag. This makes it possible for a designer to change just a single tag and experiment with type changes throughout the publication.

take-off bar

A takeoff bar or ghost bar is a rectangular solid line or pattern that is added to a press sheet and trimmed away after printing. It helps equalize ink laydown on the sheet by extending and evening out the printed area, thus avoiding ink starvation in any one place.

Such a template is useful for publications in which pages share a common design.

tensile strength
