Saddle Stitching

Stitching where the wire staples pass through the spine from the outside and are clinched in the center. Only used with folded sections, either single sections or two or more sections inset to form a single section.

Safety Paper

A paper that shows sign of erasure so that it cannot be altered or tampered with easily.

Satin Finish

A smooth delicately embossed finished paper with sheen.

Scaling

The enlargement or reduction of an image or copy to fit a specific area.

Score

Impressions or cuts in flat material to facilitate bending or tearing.

Screen Angles

The placement of halftone screens to avoid unwanted moire patterns. Frequently used angles are black 45deg, magenta 75deg, yellow 90deg, and cyan 105deg.

Screen Ruling

A measurement equaling the number of lines or dots per inch on a halftone screen.

Screened Print

A photo print made by using a halftone negative; also called a velox.

Scum

Unwanted ink marks in the non-image area.

Self Cover

A cover made out of the same paper stock as the internal sheets.

Setoff

Ink that is unintentionally transferred from the printed substrate to the back of the sheet above it as the pieces are stacked in a pile. See also: offset.

Shadow Dot

The lowest density of a halftone image.

Sharpen

To decrease the dot size of the halftone which in turn decreases the color strength.

Sheetwise

The printing of two different images on two different sides of a sheet of paper by turning the page over after the first side is printed and using the same gripper and side guides.

Short Hundredweight

A unit of mass equal to 100 pounds or 45.3 kilograms. See Also: CWT, Long Hundredweight

Short Ink

Ink that is smooth and creamy but does not flow freely.

Short Scale

Short scale is the English translation of the French term "échelle courte", which designates a system of numeric names in which the word billion means a thousand millions.
For most of the nineteenth and twentieth centuries, Great Britain uniformly used the long scale, while the United States of America used the short scale, so the two systems were often (and accurately) referred to as "British" and "American" usage, respectively. However, by the end of the 20th century almost all English-speaking countries had universally adopted the short scale, so the phrases "British usage" and "American usage" are now misleading.
Both systems have been used in France at various times in history, but the French have now settled with the long scale, in common with most other European languages.

Show Through

A problem that occurs when the printing on one side of a sheet is seen from the other side.

SI Prefix

An SI prefix is a prefix which can be applied to any unit of the International System of Units (SI) to give subdivisions and multiples of that unit.
Not all such prefixes are exclusive to SI. Many SI prefixes, and the very idea of using prefixes for this purpose, predate the introduction of the SI in 1960, so they are also quite properly used with many non-SI units.
As part of the SI system they are officially determined by the Bureau International des Poids et Mesures.
As an example, the prefix kilo multiplies by one thousand, so a kilometer is 1,000 meters, and a kilowatt is 1,000 watts. The prefix milli subdivides by a thousand, so a millimeter is one-thousandth of a meter (1000 millimeters in a meter), and a milliliter is one-thousandth of a liter. The ability to apply the same prefixes to any SI unit is one of the key strengths of the SI, since it considerably simplifies the system's learning and use.
