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 ...
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black).
Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular ...

In color management, an ICC profile is a set of data that characterizes a color input or output device, or a color space, according to standards promulgated by the International Color Consortium (ICC). Profiles describe the color attributes of a particular device or viewing requirement by defining a mapping between the device source or target ...
Dot matrix printing. Dot matrix printing, [1] sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and typically use a print ...
Under color removal. In printing, under color removal ( UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and leaving the black ink only, called a Full Black, during the color separation process. Under color removal is used in four-color (or more colors) printing.
Rich black, in printing, is an ink mixture of solid black over one or more of the other CMYK colors, [1] resulting in a darker tone than black ink alone generates in a printing process. [2] [3] A typical rich black mixture might be 100% black, 50% of each of the other three inks. Other percentages are used to achieve specific results, for ...
