Tensile Strength describes Tensile strength is related to the many stress and strain the paper is subjected to in its end-use applications. Tensile strength is the maximum force required to break a strip of paper of a given width in recommended laboratory conditions. It is also defined as kilograms per 15-millimeter width of the paper strip being tested, or the pounds-per-inch width of the paper strip. The measurement of tensile strength is in both cross-grain and grain directions. However, the tensile strength is greater when the measurement is in the grain direction. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Text Paper describes A term generally used to describe the various grades of printing paper designed for announcements, programs, deluxe printed booklets, and advertising.

Technically, thermography describes A process in letterpress printing whereby a spot of special ink is dusted with powder, while it is still wet. Afterward, the sheets are baked ensuring the fusion of the ink and powder, thereby, giving the ink a raised effect. It affects drying, adhesion, and print appearance.

Thermomechanical Pulp is A pulp made by steaming wood chips before and in the refining process, such that a higher yield is made and the pulp is stronger compared to regular groundwood. It is a method of producing printed images. Each process has distinct plate, ink, and substrate demands.

In print practice, tint means The shaded area in a paper form. It concerns the properties or grades of the paper stock.

Tint Plate means A tint plate is a printing plate which has customized surfaces for the printing of solid colors or patterns, dot arrangements, or stipple line in tints of ink. To deepen colors in an illustration, tint blocks are used. It affects drying, adhesion, and print appearance. Formulation choices influence drying time and rub resistance.

Tinting describes The process of creating a complete color tint on the press sheet in the non-image area of a paper sheet. It is achieved by dissolving ink pigments in a dampening solution. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Titanium Dioxide: chemical compound often used in coating or loading a material to increase the brightness and whiteness of the paper sheet and to contribute to its opacity. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Tolerance is The degree of variation from a pre-set standard that is permissible. It is a metric used for setup or quality evaluation.

Tooth describes A term used to describe a characteristic of a slightly rough paper which readily accepts ink. It concerns the properties or grades of the paper stock.

Top is The felt side of a paper sheet that is not against the wire in manufacture. A term used in paperboard to describe the side of a sheet of paper which exhibits the best quality. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Top-sizing is The tub sizing of a Paper that has been beater sized previously. It concerns the properties or grades of the paper stock.

Totally Chlorine-Free (TCF) refers to term used when 100 percent virgin fiber (which includes virgin tree-free fiber) is either bleached or unbleached with non-chlorine compounds. The virgin fibers can also include wood or alternative fibers such as kenaf. The term, however, cannot be used to describe recycled paper because the content of the original paper is not known. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Translucency describes The ability of a sheet of paper to transmit light without it being transparent. It concerns the properties or grades of the paper stock.

Transparent Ink is A printing ink that does not hide the color beneath it. Process inks are transparent to blend to form other colors of ink. It affects drying, adhesion, and print appearance. Formulation choices influence drying time and rub resistance.

Trapping: The ability to print a wet ink film over an ink previously printed. There are two types of trapping: wet and dry trapping. Wet trapping occurs when a wet ink is printed over a wet ink previously printed. However, when the wet ink is printed over on a previously printed dry ink or a dry palate, it is known as dry trapping. It affects drying, adhesion, and print appearance. Formulation choices influence drying time and rub resistance.

Tree-free Fiber refers to crops such as industrial hemp and kenaf that are grown because of their fiber content. These crops are more efficient per acre and usually grow faster than trees. They can also be derived from industrial by-products such as cotton scraps and agricultural by-products such as bagasse and sugarcane. It is a standard concept in printing. Usage varies with process and material.
