RAL colours colors to CMYK conversion

[_Centromedia_Com_]

I already posted times ago the request for a colour book integration into Illustrator for the missing RAL colours.
I don't know in the US, nut in Europe it's widely used, and every colour shop has RAL colours.
Therofore for those people, and me too :-), if you need a conversion you can use this link

Thanks, perhaps helpful, but I'm having doubts:

a) RAL is valid for paint colors. The final result
is a painted surface. Not paper but some real
object.

b) Knowing this, a reference to CMYK is meaningless.
And even for the case that the object is paper:
which CMYK ?

RAL colors (paint) can exceed the gamut of monitors,
RGB working spaces and CMYK spaces.

After some attempts to find more information, it
turned out that Lab (CIELab) values for RAL are
still not available.

And experienced painters know that they have to adjust colours to match RALs made by different suppliers.

Real professionals knows that RAL colours are used in painting. can't you immagine how to use them in Illustrator? How bad.

Gernot Hoffmann and Jacob Bugge can't you immagine how to use a RAL colour book to print printingplants or simply a draft copy on paper?

Why don't you ask Adobe to delete Pantone Metal colors ? Gernot Hoffmann don't metal colours exceed RGB working spaces ?

It's a useful add-on for every professional, if you don't need it don't use it.

Make a contructive forum and add useful info's instead saying a colour book isn't useful in a painting-design program.

I am all for colour books and conversions.

I merely pointed out that RAL colours may be slightly less unambiguous than CMYK.

Sorry about the ambiguity.

Adobe, please add RAL swatches (CMYK or RGB approximations) to the color swatch books in CS4. Now is the time, it is a standard you should be including. We just need to approximate colors on screen and on paper.

Meanwhile I found the source for RAL CIELab
values (and RGB,CMYK); programs, palettes etc.:

English versions are available.
