Manufacturers of printers or devices that use colour ink jet technology are meant to abide by this standard when testing for, and labeling the estimated yields of their products. The testing focused on sampling yields generated from typical business consumer printing applications.
With a CIS contact sensor, the scanner can be portable, with a height of only around 30 mm. CIS is a key component widely used in scanners (especially portable scanners), electrographs, bar code readers and optical identification technology.
Canon printers are supplied with Canon Advanced Printing Technology (CAPT), a printer driver software stack developed by Canon. The company claims that its use of data compression reduces their printer's memory requirement, good quality compared to conventional laser printers, and also claim that it increases the data transfer rate when ...
Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
Inkjet printers have traditionally produced better quality output than color laser printers when printing photographic material. Both technologies have improved dramatically over time, although the highest-quality giclée prints favored by artists use what is essentially a high-quality specialized type of inkjet printer.
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 used to print the document.
Digic 4 from Canon SX30. Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a ...
Printer steganography is a type of steganography – "hiding data within data" [30] – produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox [31] brand color laser printers, where tiny yellow dots are added to each page.
