Output variants

Using the following specific optimisations the colour fidelity of the output of RAL-colours on numerous printers, plotters, etc. is guaranteed. The most important variant is the sRGB. It should always be used when dealing with an actual monitor or colour printer and the output will not result from offset print.

Another word regarding “sRGB” (Standard RGB)


The RGB-standardisation "sRGB" was released in 2000 by HP and Microsoft in order to counteract the chaos of different RGB-displays on different output devices. Today many printers, plotters and monitors are adjusted to the sRGB-standard. The sRGB-preparation of the RAL-colours is therefore especially important. It guarantees, to some extent as the least common denominator, a good reproduction of the RAL-colours on different printers and monitors. If a certain printer is especially important to you an even better RAL-correspondence can often be achieved with the appropriate preparations. sRGB should also be used when there is no specific palette available for the printer or if the results from the palette are unsatisfactory (e.g. due to a new driver). If your device is not listed and the sRGB palette fails to deliver satisfactory results, you also have the possibility to specifically adjust the software to your output situation.
