Tack:
|
Initial adhesion
of a pressure sensitive label to a surface with a minimum of pressure
and contact time. Also the feeling of "stickiness" when
touching the surface of an adhesive.

Image File Format: |
(TIFF) A file
format for exchanging bit-mapped images (usually scans) between applications.

A pressure sensitive
construction made with a weak face so when removal is attempted the
label will break and will not come off in one piece.
|

Thermal
Dye Sublimination: |
Like thermal
printers, except pigments are vaporized and float to desired proofing
stock. Similar to Thermal Dye Diffusion Transfer, or D2T2.
|
Thermal
Transfer Printing:
|
An imprinting
method that uses heat and pressure to melt a wax based ink onto a
label or tag.
|
Thermo-mechanical
Pulp: |
In papermaking,
made by steaming wood chips prior to and during refining, producing
a higher yield and stronger pulp than regular groundwood.

TIFF/IT:
|
(Tagged Image
File Format for Image Technology) A file format based on TIFF that
provides an independent transport mechanism for raster images and

Tints:
|
Various even
tone areas (strengths) of a solid color.
|
Tipped-On
Labels:
|
A method of label
application in which the carrier is peeled back and the labels fall
or "tip" onto the surface.
|
Tolerances:
|
The specification
of acceptable variations in register, densitry, dot size, plate or
paper thickness, concentration of chemicals and other printing parameters.
|
Toner:
|
In digital printing,
imaging material also called digital inks, used in plateless printing
systems like electrophotography, magnetography, ion or electron deposition
and laser printers. In inks, dye used to tone printing inks,
especially black.
|
Toning:
|
See scum.

See Clear Coat.
|
Tooth:
|
A characteristic
of paper, a slightly rough finish that permits it to take ink readily.
|
Transfer
Tape: |
A pressure sensitive
adhesive strip applied during converting that has a liner which can
be removed to expose the adhesive. Similar to a double sided tape.
|
Transparent
Copy: |
In photography,
illustrative copy such as a color transparency or positive film through
which light must pass in order for it to be seen or reproduced.
|
Transparent
Ink: |
A printing ink
that does not conceal the color beneath. Process inks are transparent
so that they will blend to form other colors.
|
Transpose:
|
To exchange
the position of a letter, word or line with another letter, word
or line.
|
Trapping:
|
In printing,
the ability to print a wet ink film over previously printed ink.
Dry trapping is printing wet ink over dry ink. Wet trapping
is printing wet ink over previously printed wet ink. In prepress,
refers to how much overprinting colors overlap to eliminate white
lines between colors in printing. See shokes and spreads.
|
Trim
Marks: |
In printing,
marks placed on the copy to indicate the edge of the page.
|
Twin-wire
Machine: |
In papermaking,
a fourdrinier paper machine with two wires instead of one, producing
paper with less two-sideness.
|
Two-sheet
Detector: |
In printing presses,
a device for stopping or tripping the press when more than one sheet
attempts to feed into the grippers.
|
Two-sidedness: |
In paper, the
property denoting difference in appearance and printability between
its top (felt) and bottom(wire) sides.
