The G7 Method is a printing procedure used for visually accurate color reproduction by putting emphasis on matching grayscale colorimetric measurements between processes. . G7 stands for grayscale plus seven colors: the subtractive colors typically used in printing (Cyan, Magenta, Yellow, and Black) and the additive colors (Red, Green, and Blu
Grayscale images have many shades of gray in between. Grayscale images can be the result of measuring the intensity of light at each pixel according to a particular weighted combination of frequencies (or wavelengths), and in such cases they are monochromatic proper when only a single frequency (in practice, a narrow band of frequencies) is ...
The same algorithms may be applied to each of the red, green, and blue (or cyan, magenta, yellow, black) channels of a color image to achieve a color effect on printers such as color laser printers that can only print single color values.
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 grayscale-only ScanJet Plus, co-developed with Canon and released in 1989, was a massive commercial success and had a wide influence in scanner design. For almost a decade at the low end of the market, the ScanJet Plus was a de facto standard for the specifications of scanner hardware.
In contrast, developing an exposed film transforms it irreversibly; thus, development cannot be repeated. If the film is negative, the printing process must invert the image to a positive result. Like undeveloped photographic film, a raw digital image may have a wider dynamic range or color gamut than the developed film or print. Unlike ...
(1) Colour copy of non-photo blue pencil. (2) Colour copy of blue pen. (3) Grayscale copy of non-photo blue pencil. (4) Grayscale copy of blue pen. Non-photo blue (or non-repro blue) is a common tool in the graphic design and print industry, [1] [2] being a particular shade of blue that cannot be detected by graphic arts camera film. This ...
