Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp. The key in the deinking process is the ability to detach ink from the fibers. This is achieved by a combination of mechanical action and chemical means. In Europe the most common process is froth flotation deinking.

Thinner traps are less visible. Therefore, the trap width is set to a strict minimum, dictated by the maximum amount of misregistration of the entire workflow up to the press. When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when ...
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 ...
The convenience of printing thousands of pages with fewer interruptions to replenish ink. As an inkjet printer, it dispenses ink droplets at a very high speed, which allows for a relatively long distance between the printhead and the substrate, and a high drop-ejection frequency, allowing for high-speed printing.

Solid ink (also known as hot melt ink [1] [2]) is a type of ink used in printing. Solid ink is a waxy, resin-based polymer that must be melted prior to usage, unlike conventional liquid inks. Solid ink is a waxy, resin-based polymer that must be melted prior to usage, unlike conventional liquid inks.
Zink (stylised as ZINK, a portmanteau of zero and ink) is a full-color printing technology [1] for digital devices that does not require ink cartridges and prints in a single pass. [ 2 ] The printing technology and its thermal paper are developed by Zink Holdings LLC, a U.S. company, with offices in Edison, New Jersey , and Billerica ...
In printing, set-off is the term given to the unwanted transfer of ink from one printed sheet to another. 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.
