print shop asks for CMYK, any options?

Awesome, that’s more like it.

Yeah, I figured CMYK was “kind of like RGB but not sRGB or Adobe RGB”… And of course you’re right CMYK does not necessarily have a larger gamut than sRGB but I figured that a good print shop actually will have a printer with a larger gamut than sRGB. Maybe that’s where I got my assertions wrong, as @Reptorian pointed out…

This depends on what you expect. It would be quit simple to write a dt Lua script that converts a RGB Tiff file during the export to an CMYK Tiff file and adds an CMYK ICC profile. This would help everyone who needs to send an image to a print shop that ask for CMYK. But I don’t thin it would help to make better prints. Would you be happy with such a solution?

Honestly, I would expect this to be part of the “Export selection” dialog. Right now I see this:

It seems to me there should be room for custom profiles in there, including support for CMYK output profiles.

My rationale is I am a DIY kind of guy and I like to explore. And I hold Darktable to the highest standards, because it’s been doing that so well elsewhere. That means I expect to be able to deal with high-end printers out there.

But as others have told me, modern printers do not care much about CMYK vs RGB these days: as long as you have the right ICC profile applied so you can see the result, it can do the conversion for you in the back.

That is, if I understand the problem space (no pun intended) correctly, which I have been extremely bad at historically.

Thanks again
