It is crucial that offset ink resist water-in-ink emulsification (i.e., repel rather than absorb water). It also should withstand degradation by the fountain solution that covers the non-printing areas of the engraved plate. Offset ink needs to be very rich in pigment so that its full color vibrancy is perceptible, even in minute quantity. [2] [3]
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 .
The HP Indigo printing process is known for matching offset lithography's print quality [citation needed] and its application versatility, with the ability to print on a wide range of materials. It uses a proprietary printing process which is similar to the process used in laser printers, but with special electrostatically charged inks instead ...
A continuous ink system (CIS), also known as a continuous ink supply system (CISS), a continuous flow system (CFS), an automatic ink refill system (AIRS), a bulk feed ink system (BFIS), or an off-axis ink delivery system (OIDS) is a method for delivering a large volume of liquid ink to a comparatively small inkjet printhead. Many business and ...
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. [citation needed]
Similarly, spray powder is not generally used in sheet-fed (silk) screen-printing, ink-jet or toner based digital printing. In the UK, many Carrom players use a version of anti-set-off spray powder from the printing industry [ citation needed ] which has specific electrostatic properties with particles of 50 micrometres in diameter.
Waterless printing is an offset lithographic printing process that eliminates the use of water or the dampening system used in conventional printing. [1] Unlike traditional printing presses, waterless offset presses do not use a dampening solution to clear the press of ink . [ 2 ]
