Accurately Reproducing Pantone Colors on Digital Presses
Accurately Reproducing Pantone Colors on Digital Presses By Anne Howard Graphic Communication Department College of Liberal Arts California Polytechnic State University June 2012 Abstract Anne Howard Graphic Communication Department, June 2012 Advisor: Dr. Xiaoying Rong The purpose of this study was to find out how accurately digital presses reproduce Pantone spot colors. The Pantone Matching System is a printing industry standard for spot colors. Because digital printing is becoming more popular, this study was intended to help designers decide on whether they should print Pantone colors on digital presses and expect to see similar colors on paper as they do on a computer monitor. This study investigated how a Xerox DocuColor 2060, Ricoh Pro C900s, and a Konica Minolta bizhub Press C8000 with default settings could print 45 Pantone colors from the Uncoated Solid color book with only the use of cyan, magenta, yellow and black toner. After creating a profile with a GRACoL target sheet, the 45 colors were printed again, measured and compared to the original Pantone Swatch book. Results from this study showed that the profile helped correct the DocuColor color output, however, the Konica Minolta and Ricoh color outputs generally produced the same as they did without the profile. The Konica Minolta and Ricoh have much newer versions of the EFI Fiery RIPs than the DocuColor so they are more likely to interpret Pantone colors the same way as when a profile is used. If printers are using newer presses, they should expect to see consistent color output of Pantone colors with or without profiles when using default settings. -

Ultra HD Playout & Delivery
Ultra HD Playout & Delivery SOLUTION BRIEF The next major advancement in television has arrived: Ultra HD. By 2020 more than 40 million consumers around the world are projected to be watching close to 250 linear UHD channels, a figure that doesn’t include VOD (video-on-demand) or OTT (over-the-top) UHD services. A complete UHD playout and delivery solution from Harmonic will help you to meet that demand. 4K UHD delivers a screen resolution four times that of 1080p60. Not to be confused with the 4K digital cinema format, a professional production and cinema standard with a resolution of 4096 x 2160, UHD is a broadcast and OTT standard with a video resolution of 3840 x 2160 pixels at 24/30 fps and 8-bit color sampling. Second-generation UHD specifications will reach a frame rate of 50/60 fps at 10 bits. When combined with advanced technologies such as high dynamic range (HDR) and wide color gamut (WCG), the home viewing experience will be unlike anything previously available. The expected demand for UHD content will include all types of programming, from VOD movie channels to live global sporting events such as the World Cup and Olympics. UHD-native channel deployments are already on the rise, including the first linear UHD channel in North America, NASA TV UHD, launched in 2015 via a partnership between Harmonic and NASA’s Marshall Space Flight Center. The channel highlights incredible imagery from the U.S. space program using an end-to-end UHD playout, encoding and delivery solution from Harmonic. The Harmonic UHD solution incorporates the latest developments in IP networking and compression technology, including HEVC (High- Efficiency Video Coding) signal transport and HDR enhancement. -

How to interpret the sRGB color space (specified in IEC 61966-2-1) for ICC profiles A. Key sRGB color space specifications (see IEC 61966-2-1 https://webstore.iec.ch/publication/6168 for more information). 1. Chromaticity co-ordinates of primaries: R: x = 0.64, y = 0.33, z = 0.03; G: x = 0.30, y = 0.60, z = 0.10; B: x = 0.15, y = 0.06, z = 0.79. Note: These are defined in ITU-R BT.709 (the television standard for HDTV capture). 2. Reference display‘Gamma’: Approximately 2.2 (see precise specification of color component transfer function below). 3. Reference display white point chromaticity: x = 0.3127, y = 0.3290, z = 0.3583 (equivalent to the chromaticity of CIE Illuminant D65). 4. Reference display white point luminance: 80 cd/m2 (includes veiling glare). Note: The reference display white point tristimulus values are: Xabs = 76.04, Yabs = 80, Zabs = 87.12. 5. Reference veiling glare luminance: 0.2 cd/m2 (this is the reference viewer-observed black point luminance). Note: The reference viewer-observed black point tristimulus values are assumed to be: Xabs = 0.1901, Yabs = 0.2, Zabs = 0.2178. These values are not specified in IEC 61966-2-1, and are an additional interpretation provided in this document. 6. Tristimulus value normalization: The CIE 1931 XYZ values are scaled from 0.0 to 1.0. Note: The following scaling equations can be used. These equations are not provided in IEC 61966-2-1, and are an additional interpretation provided in this document. 76.04 X abs 0.1901 XN = = 0.0125313 (Xabs – 0.1901) 80 76.04 0.1901 Yabs 0.2 YN = = 0.0125313 (Yabs – 0.2) 80 0.2 87.12 Zabs 0.2178 ZN = = 0.0125313 (Zabs – 0.2178) 80 87.12 0.2178 7. -

Spectral Primary Decomposition for Rendering with RGB Reflectance
Eurographics Symposium on Rendering (DL-only Track) (2019) T. Boubekeur and P. Sen (Editors) Spectral Primary Decomposition for Rendering with sRGB Reflectance Ian Mallett1 and Cem Yuksel1 1University of Utah Ground Truth Our Method Meng et al. 2015 D65 Environment 35 Error (Noise & Imprecision) Error (Color Distortion) E D CIE76 0:0 Lambertian Plane Figure 1: Spectral rendering of a texture containing the entire sRGB gamut as the Lambertian albedo for a plane under a D65 environment. In this configuration, ideally, rendered sRGB pixels should match the texture’s values. Prior work by Meng et al. [MSHD15] produces noticeable color distortion, whereas our method produces no error beyond numerical precision and Monte Carlo sampling noise (the magnitude of the DE induced by this noise varies with the image because sRGB is perceptually nonlinear). Contemporary work [JH19] is also nearly able to achieve this, but at a significant implementation and memory cost. Abstract Spectral renderers, as-compared to RGB renderers, are able to simulate light transport that is closer to reality, capturing light behavior that is impossible to simulate with any three-primary decomposition. However, spectral rendering requires spectral scene data (e.g. textures and material properties), which is not widely available, severely limiting the practicality of spectral rendering. Unfortunately, producing a physically valid reflectance spectrum from a given sRGB triple has been a challenging problem, and indeed until very recently constructing a spectrum without colorimetric round-trip error was thought to be impos- sible. In this paper, we introduce a new procedure for efficiently generating a reflectance spectrum from any given sRGB input data. -

Painting with Light: a Technical Overview of Implementing HDR Support in Krita
Painting with Light: A Technical Overview of Implementing HDR Support in Krita Executive Summary Krita, a leading open source application for artists, has become one of the first digital painting software to achieve true high dynamic range (HDR) capability. With more than two million downloads per year, the program enables users to create and manipulate illustrations, concept art, comics, matte paintings, game art, and more. With HDR, Krita now opens the door for professionals and amateurs to a vastly extended range of colors and luminance. The pioneering approach of the Krita team can be leveraged by developers to add HDR to other applications. Krita and Intel engineers have also worked together to enhance Krita performance through Intel® multithreading technology, while Intel’s built-in support of HDR provides further acceleration. This white paper gives a high-level description of the development process to equip Krita with HDR. A Revolution in the Display of Color and Brightness Before the arrival of HDR, displays were calibrated to comply with the D65 standard of whiteness, corresponding to average midday light in Western and Northern Europe. Possibilities of storing color, contrast, or other information about each pixel were limited. Encoding was limited to a depth of 8 bits; some laptop screens only handled 6 bits per pixel. By comparison, HDR standards typically define 10 bits per pixel, with some rising to 16. This extra capacity for storing information allows HDR displays to go beyond the basic sRGB color space used previously and display the colors of Recommendation ITU-R BT.2020 (Rec. 2020, also known as BT.2020). -
