In printing, bleed is printing that goes beyond the edge of where the sheet will be trimmed. In other words, the bleed is the area to be trimmed off. The bleed is the part on the side of a document that gives the printer a small amount of space to account for natural movement of the paper during guillotining, [1] and design inconsistencies ...
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
Straight pen-drawn line color bleeding, causing jagged edges. Use of the term in prior art involved unwanted propagation of single color due to capillary action in paper fibers and other factors. In printing and graphic arts , mixing of two dissimilar colors in two adjacent printed dots before they dry and absorb in substrate is referred to as ...
Any space between columns of text is a gutter.) The top and bottom margins of a page are also called "head" and "foot", respectively. The term "margin" can also be used to describe the edge of internal content, such as the right or left edge of a column of text. [3] Marks made in the margins are called marginalia.
Since there is no added white space built into a typical full stop (period), other than that above the full stop itself, full stops contribute to the river effect in a limited way. At one time, common word-processing software adjusted only the spacing between words, which was a source of the river problem.
Decrease in rag fibre quality may be a culprit; as demand for paper rose in later centuries, papermakers used less water and spent less time cleansing the rag fibres used to make paper. [4] An early work of art to have been affected by foxing is the Portrait of a Man in Red Chalk , a drawing on paper by Leonardo da Vinci .
Non-printing characters or formatting marks are characters for content designing in word processors, which are not displayed at printing. It is also possible to customize their display on the monitor. The most common non-printable characters in word processors are pilcrow, space, non-breaking space, tab character etc. [1] [2]
It would be impractical to remove this much lignin by bleaching, and undesirable since one of the big advantages of mechanical pulp is the high yield of pulp based on wood used. Therefore, the objective of bleaching mechanical pulp (also referred to as brightening) is to remove only the chromophores (color-causing groups).
