Stocking merchants refers to paper merchant that fills his warehouse with lots of papers and supplies the market regularly ensuring that there is no lack or scarcity. This merchant saves the seller the Delay that is associated with purchasing from the manufacturers. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Technically, stopover describes side-by-side exposure. It is multiple impositions made on a lithographic press plate. It is done by repeating the exposure if a flat by stepping it along the edge of the gripper. It is equipment used for production or quality control. Calibration is essential for reliable results.

Stopping out is applying opaque to photographic negatives. It is also the application of the lacquer to protect certain positive areas in dot etching. It also involves the protection of specific areas in plates with deep-etched in order that no ink may be deposited on the supposed protected areas. It affects drying, adhesion, and print appearance. Formulation choices influence drying time and rub resistance.

Stream feeder refers to type of press feeder that keeps overlapped sheets of papers moving towards the grippers. It concerns the properties or grades of the paper stock.

Stretch: term that properly describes the "give" of papers when tensile pressure is applied. It concerns the properties or grades of the paper stock.

Stretch resistance — measured by a tensile testing instrument. It helps the paper to resist stress while it is in use. It concerns the properties or grades of the paper stock.

Strike-in describes When a printing ink enters into or penetrates a sheet of paper. It concerns the properties or grades of the paper stock.

Strike-through describes When a printing ink penetrates or passes through a sheet of paper. It concerns the properties or grades of the paper stock.

String and button envelope means An envelope that is made with dual reinforcing paper buttons. The first of these buttons are placed on the flap of the envelope while the other is placed at the back of the envelope. To close a string button envelop, the locked string under the flap button is wound around the two buttons. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Strip-in refers to Also known as a setting is a negative which must be combined with another in order to have a single page negative that contains all components. It is a standard concept in printing. Usage varies with process and material.

Stripping is In photoengraving, stripping means a film which contains the photographic image from the wet plate that is then moved and turned around. In offset, stripping is negatives that are properly positioned on a masking sheet. It is a metric used for setup or quality evaluation. Higher values do not always imply better quality; context matters.

Substance weight: The same as basis weight. It is a standard concept in printing.

Sucker can be defined as that rubber suction cup that is found on machine feeding devices. It is a standard concept in printing.

In print practice, suction box means device that removes the water found in the paper machine. It is done by a suction action that is located under the wire located at the wet end. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Suction feed — term that is applied to suction grippers whose duty is to feed papers. It concerns the properties or grades of the paper stock.

Technically, sulfate describes also known as the crafting process. The alkaline process of cooking a pulp. Sodium Sulphate and sodium sulfide are two substances used in cooking woodchips to high brightness without any form of fiber degradation whatsoever. It is a metric used for setup or quality evaluation. Higher values do not always imply better quality; context matters.

Sulfite: The cooking of Woodchips in a disulfide solution. The use of acid in the cooking pulp. It is a standard concept in printing. Usage varies with process and material.

Supercalender refers to off machine calendar roles that first heat and then iron the paper to give it a high gloss finish. It concerns the properties or grades of the paper stock.

Within the trade, supercalendering refers to alternating roll of compressed cotton in a stack and highly polished steel. The paper in this process the paper is "ironed" by the compressed cotton roll. That is, it is subjected to a heated steel roll. After this "ironing" process, the paper would have a gloss finish. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.

Surface plate commonly denotes one of the two major types of lithographic press-plate. Basically, a colloid image is formed on the light-sensitized plate that is made of metal. It is done by the action of actinic light which passes through the photographic negatives. It is equipment used for production or quality control. Calibration is essential for reliable results.

Surface sized describes term which refers to a paper that has been sized by the application of a sizing agent to the paper when the paper is not completely dried. The aim of this kind of sizing is to increase the paper's resistance to ink penetration. It concerns the properties or grades of the paper stock. Selection affects stiffness, opacity, and printability.
