Digitale Farbkommunikation zwischen verschiedenen Anwendungen, Betriebssystemen und Produktionssystemen ber\u00fchrt in vielen Bereichen die Frage kommerzieller versus offener Lizenzen. Dieser Artikel gibt eine Einf\u00fchrung in das Thema und beschreibt die Leitlinien des freieFarbe e.V. im Umgang mit Standards und Lizenzen.<\/em><\/p>\n Wenn wir einen Blick auf Farbe vom Design bis zum fertigen Produkt werfen, dann zeigt sich uns ein \u00d6kosystem kommerzieller Anwendungen und Produktionssysteme verschiedener Hersteller. Um Farb-Informationen reibungslos innerhalb dieses \u00d6kosystems auszutauschen, m\u00fcssen zwei Voraussetzungen erf\u00fcllt sein:<\/p>\n <\/p>\n werden von internationalen Standardisierungs-Organisationen gepflegt. Einige relevante Organisationen und Standards sind:<\/p>\n Im Jahr 1976 ver\u00f6ffentlichte die CIE das CIE 1976 L*a*b \/ L*C*h* Farbsystem, um Farbe auf reflektierenden Oberfl\u00e4chen unabh\u00e4ngig von der Art des Objektes zu beschreiben. Mit dem CIE 1976 L*a*b \/ L*C*h* Farbsystem k\u00f6nnen Farben im Bereich farbigen Oberfl\u00e4chen und bedruckter Objekte gemessen, spezifiziert und kommuniziert werden.<\/p>\n Spielt Farbe eine Rolle in der industriellen Produktion \u2013 z.B. bei farbigen Oberfl\u00e4chen \u2013 so gibt es dazu in der Regel einen ISO Standard. ISO arbeitet mit CIE zusammen, um z.B. gemeinsame Standards heraus zu bringen oder diese gegenseitig zu referenzieren. Wichtige ISO-Standards f\u00fcr Projekte von freieFarbe e.V. sind u.a.:<\/p>\n Der ICC-Standard ist der defacto-Standard f\u00fcr Farbmanagement in Softwares f\u00fcr Windows, MacOSX inkl. angebundener Drucksysteme in den Bereichen professionelle digitale Fotografie sowie professionelle Drucksachen inkl. Verpackungsdruck. Zus\u00e4tzlich ist er als ISO 15076 Standard verf\u00fcgbar.<\/p>\n Basierend auf Vorarbeiten von Microsoft und HP hat die IEC 1999 den Standard Diese Standards-Familie beschreibt u.a. den sRGB Farbraum eines standardisierten Computer-Farbmonitors. sRGB ist heute der defacto-Standard in Web und Mobile Media, Digitalfotografie mit Consumer Kameras und Office Software. sRGB IEC 61966<\/span>-2-1:1999<\/a> ist weiterhin die Farbreferenz f\u00fcr alle W3C Standards im Bereich Web und Mobile Media.<\/span><\/p>\n Wir vom FreieFarbe e.V. haben uns zum Ziel gesetzt, dass eine digitale Farbkommunikation zwischen verschiedenen kommerziellen L\u00f6sungen vom Design bis zur Produktion als auch zu Open Source Anwendungen problemlos m\u00f6glich ist.<\/p>\n Um dieses zu erm\u00f6glichen, stellen wir unsere Tools unter einer Creative Commons Licence Attribution 4.0<\/a>, zur Verf\u00fcgung, welche\u00a0 erm\u00f6glicht, die Tools zu modifizieren und sowohl in kommerzielle als auch Opensource-Anwendungen zu integrieren. FreieFarbe e.V. begr\u00fc\u00dft und unterst\u00fctzt Open Source Projekte im Bereich Farbe. Unser Ziel ist es, eine reibungslose digitale Farbkommunikation zwischen beliebigen kommerziellen L\u00f6sungen sowie auch Open Source Anwendungen zu erm\u00f6glichen. Daher liegt unser Schwerpunkt auf der Nutzung offener Standards und weniger auf Open Source.<\/p>\n Weiterf\u00fchrende Informationen zu Open Source Projekten im Bereich Farbe gibt es\u00a0hier.<\/a>[:en]Jan-Peter Homann and the board of freieFarbe e.V.<\/em><\/p>\n Digital color communication between different applications, operating systems and production solutions touches in several areas the field of commercial versus open licences. This article gives an introduction to this topic and describes how the team of freecolour.org (freieFarbe e.V.) handles these issues.<\/em><\/p>\n If we have a look on color from design to the final product, we see an ecosystem of commercial solutions and production solutions from different vendors. To exchange smooth and easy color data inside this eco system, two things are necessary:<\/p>\n Projects maintained and published by the team of freecolour.org (freieFarbe e.V.) are based on open standards for colour.<\/strong><\/p>\n <\/p>\n Open standards are maintained by global standardization bodies. Some relevant standardization bodies in the area of colour are:<\/p>\n In 1976, CIE published the CIE 1976 L*a*b\/L*C*h* color system to describe color on reflecting objects independently from the type of object. The CIE 1976 L*a*b color system can be used to measure colour, specify and communicate color e.g. in the area of painted surfaces or printed objects.<\/p>\n If color is connected to industrial production and e.g. painted surfaces, it is probably standardized by ISO. ISO cooperates with CIE by publishing e.g. joined standards and by referencing each other standards. From a broad view on color, paint and ink, and industrial production, there are dozens or even hundreds of ISO standards which are connected to color.<\/p>\n Some relevant standards for freecolour.org (freie Farbe e.V) are e.g:<\/p>\n For color critical work in Windows, Mac and LINUX applications including connected printing systems as also the area of professional digital photography, commercial and packaging printing: colormanagement with ICC profiles is the defacto standard and also standardized through ISO 15076.<\/p>\n Based on work from Microsoft and HP, IEC published the standard IEC 61966<\/span>-2-1:1999 <\/a> – Multimedia systems and equipment – Colour measurement and management.<\/span><\/p>\n This family of standards is describing e.g. the sRGB colorspace of an standardized computer display. sRGB is the defacto color standard in web and mobile media, consumer digital photography and office applications. sRGB IEC 61966<\/span>-2-1:1999<\/a> is also the colour reference for all W3C standards for web and mobile media.<\/span><\/p>\n Through the sRGB ICC profile, color data from these sectors can be interchanged with the graphic arts world. <\/span><\/p>\n The freecolour.org team (freieFarbe e.V) welcomes and supports all open source projects related to digital color. Our goal is to make digital color flow both through commercial design and production solutions as also through open source applications. So we are more focused on Open Standard than on Open Source.
