Differences between RBG and CMYK color profiles

For the best representation in the web (RGB) and for print (CMYK), renderings with a correct color profile have to be stored. First off: Do not worry, Studio 2038 always ships 2 optimized versions: By default, the RGB versions are the best on the web, plus the CMYK version for printing - no extra cost! Nevertheless, we want to show what makes the difference RGB - CMYK.

RGB color profile

RGB stands for the three primary colors Red Green and Blue, that make up the additive color space.

These three basic colors are light colors, which means that color is created by mixing light . That means, approx. 16.8 million shades . The RGB color space refers to all images that are displayed on a screen (= light), such as Monitor (website, social media, online shop ...), smartphone, tablet, TV, screen, presentation on a projector ... This gives the possibility to digitally display fresh, saturated and bright colors.

CMKY color profile

CMYK is composed of the three colors cyan, magenta and yellow and the key color black as a subtractive color model.

All images, e.g. for magazines, brochures, posters, banners or roll-ups for trade fairs etc., must be deposited in a CMYK color profile (e.g., IsoCoated V2). This means that theoretically it is possible to print over 4 billion colors . In addition, the resolution at a print size of DIN A3 is best 300 DPI, so that the image is not pixelated printed and looks blurred. See also: The right resolution for CGI renderings!

Since paper does not light up in contrast to a monitor, the colors may look falsified when printed, provided the color profile has not been defined correctly before.

So you can not print RGB?

No, even if an RGB image is sent to a printer, the printer "secretly" profiles and automatically splits the image into a CMYK profile. If this is not done manually in advance, there are some unpleasant surprises in the color illustrations. The result is the effect of color distortions. Therefore, Studio 2038 delivers both RGB for the web and the correct CMYK in the required resolution for printing so that all colors match the original as much as possible.

Check color fastness with proofs

Print a rendering on the office printer and judge the colors? Not a good idea. Too many factors such as color, paper, print settings, different office and daylight affect the objective color perception. When it comes down to it, colors need to be rated correctly.

The D50 standard light describes a defined lighting conditions according to the ISO standard. Thus, it is possible to look at and evaluate proofs consistently. A proof (dt. Prüfdruck) refers in printing the anticipated simulation of a print result for revision.

A proof is printed on high quality paper from a calibrated special (expensive) printer (proofer). The stored color profile (for example IsoCoated V2) with its respective printing properties is also taken into account. Each proof contains a media wedge . This means that the printer can detect deviations based on the media wedge.

 

Difference RGB CMYK - We deliver the right color profile

If desired, we can also deliver CGI renders optionally as professional printed proofs with the desired color profile and in the desired size. So that the colors and the print result can be rated better. CGI animations are always in the RGB profile because we can not print them and only display them on a screen become.

Does everything sound like rocket science? On the basis of the purpose of use, we are of course happy to advise and deliver the correct data required!
