Which RGB working colour space is suitable for colour-consistent work?

In the early days of color spaces Apple and e.g. Photoshop up to version 5.5 set the monitor color space as working color space by default. But it soon became clear that a design office would be working with 10 Macs in 10 different color spaces. A neutral concept was needed.

There are many RGB Colour Spaces around. In the area of print media there are currently primarily three different variants: sRGB, AdobeRGB(1998) and eciRGB_V2.

The sRGB color space is widely used in digital cameras and is the industry leader in the consumer segment. Problem for printing: sRGB is a relatively small color space, and does not cover the color possibilities of modern offset printing systems and digital printers. Since offset printing profiles such as ISOCoated_v2 have a much larger color space, it makes little sense to perform retouching in sRGB.

From our point of view eciRGB_V2, a further development of eciRGB, is optimal. This color space has been specially created for use in the printing sector and offers some strengths:

  • It covers the colors of all modern printing color spaces (offset, gravure, web offset, newspaper), but is not much larger and therefore does not give away any resolution.
  • Equal shades of red, green and blue result in neutral shades of grey
  • Between 0/0/0 and 50/50/50 there is roughly the same distance as between 50/50/50 and 100/100/100.
  • The white is 5000 Kelvin and the gamma is 1.8 Kelvin.

The eciRGB_v2 color space can be downloaded free of charge from the pages of the European Color Initiative (ECI).

The AdobeRGB 1998 color space, which has been widely used by Adobe since Photoshop 5.5 and today in all parts of the Adobe product range, is also well suited for the printing sector, but works with a gamma of 2.2 and is designed for degrees of whiteness from D50 to D65. All common print color spaces can also be well mapped in AdobeRGB 1998. You can find Adobe documentation on this color space here.

  1. Das kam heute per Email von Datacolor: Ein kostenloses Tutorial für die Schwarz Weiss Fotografie mit folgemdem Inhalt:

    “Neben der Kalibrierung von Monitoren und Druckern spielen die Farbeinstellungen in Photoshop (Lightroom, Indesign, Illustrator, …) eine entscheidende Rolle. Experten wie der Trainer Jens Eilers und der Fachautor Christian Piskulla sind sich hier erfreulich einig: Für die meisten Anwendungen empfehlen sie die Profile der European Color Initiative, kurz ECI. Die Spezialisten stellen auf ihrer Homepage eine Vielzahl von ICC-Profilen zum kostenlosen Download bereit, ergänzt um weitere Unterlagen rund ums Farbmanagement und digitale Arbeitsabläufe. Konkret bedeutet das: Laden Sie die Profile “eciRGB v2” und “ISO Coated v2 (ECI)” herunter. Kopieren Sie sie anschließend in “WINDOWS/ system32/spool/drivers/ color” oder in “Benutzer/ Benutzername/Library/ ColorSync/Profiles”. Jetzt wählen Sie die beiden Arbeitsfarbräume aus. Für einen rein fotografischen Workflow kann der Farbraum “Adobe RGB” eine Alternative sein. Behalten Sie in Dateien eingebettete Profile bei.”

    Viele Grüße an Proof.de, Sie waren also einiges früher dran als die Experten von Datacolor 🙂

    Mit besten Grüßen
