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 copiers produce on every printed page that identifies the specific device that was used ...
In 1963, Xerox introduced the Xerox 813, the first desktop plain-paper copier, realizing Carlson's vision of a copier that could fit on anyone's office desk. Ten years later, in 1973, a basic, analogue, color copier, based on the 914, followed. The 914 itself was gradually sped up to become the 420 and 720.
Color management is the process of ensuring consistent and accurate colors across various devices, such as monitors, printers, and cameras. It involves the use of color profiles, which are standardized descriptions of how colors should be displayed or reproduced. Color management is necessary because different devices have different color ...
Xerography is a dry photocopying technique. [1] Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρός xeros, meaning "dry" and -γραφία-graphia, meaning "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals.
e. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [1] The drum then selectively collects electrically charged ...
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
The printing press check is a step in the printing process. It takes place after a printing press is set up but before the print run is underway. Herzliya Airport (Israel) Runway location and Traffic Pattern chart (left) was erroneously printed as a result of "black layer" 180° misplacement. The corrected chart is on the right.
The Xerox Phaser 7700 Series of color laser printers use the VxWorks Operating System on its 20GB PATA IDE Hard Drive. The 7700 Series is a wide format duplex-capable laser printer capable of printing up to 12x18 page sizes. The average 8.5x11 Letter size speed is 23 pages per minute. ()
