The components in detail:

  • Atlas PDF: Its top layer corresponds to the printed version available as a ring binder, and the file contains further layers with the gamuts for sRGB, ISO Coated V2, Coated FOGRA39, PSO Coated V3 (FOGRA 51), and PSO Uncoated V3 (FOGRA52). These allow you to quickly check whether a colour can be exactly reproduced in an output process. The PDF contains Lab colour data, and you can print the atlas yourself (the accuracy depends on your system and colour settings).
  • PDF with sRGB and CMYK colour values for all colours and software applications of all kinds. With Ctrl+F you can quickly search for colour names.
  • ASE colour library that can be loaded into Adobe software as the “HLC Colour Atlas” colour library. Contains all atlas colours with their exact Lab colour values (only standard atlas version).
  • Measurement report of all colours (XLS). For each colour swatch, the Lab colour value and the target/actual deviation are specified in the ring binder version (see below). The spectral data of this measurement are also included.
  • Spectral data adapted to the exact HLC values for the determination of colour formulations for all colour tones of the printed atlas without deviation from the target (XLS, CXF, CGATS)

The ring binder versions produced in highly accurate proof printing can be ordered from proof GmbH, CCVision and grafipress. State-of-the-art inkjet technology reproduced all colours in the measured master copy with an accuracy of DeltaE00<1 (average DeltaE00=0.5) – a printing accuracy that was unthinkable just a few years ago.

Colour range overview

RGB-Atlas A complete overview of the RGB colour range, in A4, as a A0 print sheet and as a separate overview of the pastel tones. Print this file in your output situation and use the RGB colour samples as a reference for your software. RGB Atlas (single pages).pdf
RGB Atlas (print sheets).pdf
RGB Atlas Pastels.pdf
CMYK-Atlas (10% steps) A complete overview of the CMYK colour range, in A4, and as A0 print sheet. This is how to use a desired colour in your software: Print the pdf file in your output situation (Postscript device and driver necessary), look for the most similar colour sample, then take the CMYK colour values mentioned in the atlas to use the colour in your software. CMYK Atlas (single pages).pdf
CMYK Atlas (print sheets).pdf
CMY atlas (5% steps, up to 50%) A finer gradation by cyan, magenta, yellow up to 50% each, combined on one print sheet. Practical for matching pastel shades, or if the process is printing too dark (thanks to Christian Schmidt for the files) cmy-atlas.pdf
(CorelDraw X7)
Lab-Atlas A complete overview of the Lab colour range in A4. This is how to use a desired colour in your software: Print the pdf file in your output situation, look for the most similar colour sample, zhen take the Lab colour values mentioned in the atlas to use the colour in your software. This file is also a good overview of the Lab colour range, although the RGB/CMYK gamut or the actual limit of the CIELAB colour range are not displayed. LAB Atlas (single pages).pdf

LAB Atlas (print sheets).pdf
CIE-HLC-CMYK-Gamut HLC are the better CIELAB coordinates, because hue, lightness and chroma (colour tone, brightness and saturation) are intuitively understandable. The print file shows on 36 individual pages the colours which are available in the FOGRA39-CMYK gamut, in systematic HLC order – in total 1032 colours. andruck_lab.pdf

Colour conversion with Excel / VBA

Lab/HLC (Excel) HLC are the Lab polar coordinates. Hue / Lightness / Chroma are far more intelligible than L, a, b. Since CIELAB is not restricted to gamuts, the calculation takes our perception into account, and no copyright hinders from free use, it is in our opinion the best colour model. It has prevailed in a wide range of industries, but not yet with the normal user. With this table, you can quickly convert hundreds Lab colours into understandable HLC form and vice versa. labhlc.xls

Open Source VB.NET library for colour conversion. It calculates all known colour ranges, including sRGB, Lab, HLC. Also exotic such as Luv / LCHuv. Various colour differences: DeltaE76 / 94/2000 / CMC. Can also be installed free of charge in commercial products. By Tom Pažourek, a developer from Brno, Czech Republic. Colourful
Pascal Getreuer

ICC Profiles

Here are the most important ICC profiles, which are used in practice.

sRGB Standard RGB by HP/Microsoft has become a general standard for the RGB representation on monitors and printers – although it has a smaller gamut than, for example, CIE-RGB. sRGB is preinstalled as the default colour space in most operating systems. CMYK output is easily possible by means of a media-neutral PDF/X-4 print file. sRGB-Profile of ICC
European Colour Initiative (ECI) The profile “eciRGB v2” (recommended as working space for high-end photography and prepress) and other ICC profiles for various printing conditions can be found in the ECI download area. Useful additional information. ICC-Profiles of ECI
bvdm ProzessStandard Offsetdruck In its MediaStandard Print, the Federal Association for Printing and Media bvdm recommends the profiles “PSO Coated v3” (FOGRA51, For multi-coated, moderately lightened papers) and “PSO Uncoated v3” (FOGRA52, for uncoated, highly lightened papers, wood-free white). Ask your service provider whether they have already switched from PSO v2 (FOGRA39 etc.) to PSO v3 before you create your print data with the new profiles. PSO Coated v3 (ECI)
PSO Uncoated v3 (ECI) Comprehensive collection of ICC profiles for numerous application areas, based on Fogra characterization data (PSO v2, FOGRA39, etc.) and generated with software from basICColor (Karl Koch, Penzberg). In addition, the website provides test images for the Lab colour space and for monitor calibration. basICColor profiles
Profile packages from Adobe The colour profiles supplied by Adobe in its products are also available as a separate download. The package includes “Adobe RGB (1998)” as well as the widely used ICC profile “Coated FOGRA39 (ISO 12647-2:2004)” for sheetfed offset which, however, does not comply with the current standard ISO 12647-2:2013 characterized by FOGRA51).
