Tear-off horizontal perforations at page top/bottom are exactly in-between standard perforations, at whatever regular interval is used for that particular paper. When the perforated edges of the paper are manufactured so that they tear off the pages in strips, those strips are known as "perfory."
The problem can occur with most types of printing, and is avoided by the use of slipsheets between copies (so any ink transfer occurs onto discardable paper) or anti-set-off spray powder. The term in offset printing also refers to the unwanted transfer of ink to rollers and friction points throughout the printing press. Ink that is not properly ...
It is useful to evaluate web runability, controlling the quality of newsprint and characterizing the toughness of packaging paper. Tear strength for paper is measured in units of force, frequently measured with the Elmendorf Tester. Tear Factor is tear strength per unit basis weight, Tear_Strength/Grammage, or N/g/m 2.
This method, using small measured registration marks on both the stone and the paper, is very accurate and simple to do. The printer measures the exact size of the paper and the desired margins. Then marks are made at both ends of the sheet of paper, and corresponding marks (usually in the shape of a "T") are made on the stone.
In printing, trap expresses the degree to which ink already printed on a substrate accepts another layer printed on top of it compared to how well the substrate (e.g., paper) accepts that ink. However, in the era of prepress software, the term came to refer to compensation for misregistration (when two layers of ink are not perfectly aligned ...

The problem can occur with most types of printing. Anti-set-off spray powder is generally made from natural starches from plants and vegetables. There remains a demand for soluble powders (sometimes known as vanished powders) based on natural sugars [ 1 ] which are often used when the final printed sheet is to be varnished.
