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.
The Monochrome Display Adapter (MDA, also MDA card, Monochrome Display and Printer Adapter, MDPA) is IBM's standard video display card and computer display standard for the IBM PC introduced in 1981. The MDA does not have any pixel-addressable graphics modes, only a single monochrome text mode which can display 80 columns by 25 lines of high ...
To use the Hexachrome process in a digital printing process, Pantone produced a plugin for Adobe Photoshop that allowed the designer to work in an RGB color space more typical of computer work. [2] The plugin was called HexWare, which contained a set of Adobe plugins used by printers and designers who used the Hexachrome system. [2]
In printing, registration black is a black color that includes 100% of each of the process colors used. Typically these are cyan, magenta, yellow and black , [4] but if different colors are used, registration black marks are made with all of the colorants (inks). [4] Registration black is used for printing crop marks and registration marks ...
Some printing presses are capable of printing with both four-color process inks and additional spot color inks at the same time. High-quality printed materials, such as marketing brochures and books, often include photographs requiring process-color printing, other graphic effects requiring spot colors (such as metallic inks), and finishes such ...
The purpose of this standard is to specify an input data file, a measurement procedure and an output data format to characterize any four-color printing process. The output data (characterization) file should be transferred with any four-color (cyan, magenta, yellow and black) halftone image files to enable a color transformation to be ...
A method of full-color printing is six-color process printing (for example, Pantone's Hexachrome system) which adds orange and green to the traditional CMYK inks for a larger and more vibrant gamut, or color range. However, such alternate color systems still rely on color separation, halftoning and lithography to produce printed images.
Color printers usually have a higher cost per page than monochrome printers, even if printing monochrome-only pages. Liquid electrophotography (LEP) is a similar process used in HP Indigo presses that uses electrostatically charged ink instead of toner, and using a heated transfer roller instead of a fuser, that melts the charged ink particles ...
