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 photocopiers produce on every printed page that identifies the specific device that was ...
The Portable document format (PDF) also includes a spot color called All, with the same restrictions, starting with PDF 1.2. Note that a PDF spot color must also include a "tint transform" which translates spot values into a different color space for viewing on screen, or printing to printers without spot color support. There is no special rule ...
Pixel formats used in Y'CbCr can be referred to as YUV too, for example yuv420p, yuvj420p and many others. In a similar vein, the term luminance and the symbol Y are often used erroneously to refer to luma, which is denoted with the symbol Y'. The luma (Y') of video engineering deviates from the luminance (Y) of color science (as defined by CIE).
It also standardizes the appropriate method of describing the yield of cartridges in documentation supplied to the consumer by the manufacturer. 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.
A color is described as a Y′ component and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance. [1] Today, the term YUV is commonly used in the computer industry to describe colorspaces that are encoded using YCbCr. [2]
Two cartridges; one with black ink (a third-party HP 15 compatible cartridge), one with colored inks (an original type HP 17 tri-color cartridge) currently installed in an HP inkjet printer. An ink cartridge or inkjet cartridge is a component of an inkjet printer that contains ink to be deposited onto paper during printing . [ 1 ]
Fentanyl has made headlines for driving overdose deaths, but the Centers for Disease Control and Prevention is warning of the rise of an even deadlier drug. An addiction specialist weighs in.
YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.
