Hi,
I am a more than 10year Linuxuser now, and I all my environment (personal and business) I try to use and distribute free software as much as I can. My wife is a pro photographer, working mostly with Lightroom on windows (could not yet get to convert her). Luckily she works better with Gimp 2.10 than with Photoshop. She likes Gimp more (what makes me super happy).
Now we wanted to create a kind of flyer and send the files to a printing company (flyeralarm.de) here in Germany.
Now my question is such: There is - naturally - a huge difference between rgb and cmyk. “Professionals” would create a Photoshop Project directly in CMYK colorspace to work in it, to avoid huge color differences to rgb.
Now we created a wonderful graphic in Gimp, and asked ourselfs: what would be the best way to convert it to cmyk colorspace? We OWN photoshop, but my goal is to get away from all adobe products (she doesnt use but lightroom); is this separat++ plugin (never tried it) good / pro enough to convert it in gimp?
I also checked out, that Krita can convert it to CMYK, but after that it looks totally the same (what cant be, right?)
How would you do that?
And:
Is there a software I could create such a (printing) project directly beginning in the cmyk ?
hey paperdigits. thanks for your answer and help. Krita is the way I will got I think. I will take the graphic that I compozed in Gimp (because my gimp skills are better that other skills) , loaded the finished jpg-file in krita an just converted it. This method was easiest and seems to be ok.
So great to hear that a dev works on cmyk support for gimp. Do you have any further info or link to an info about this?
thanks again, and kind regards
Depending on your needs, you might also want to try my PhotoFlow editor. It has basic CMYK support. It is for example possible to open a RAW, Jpeg or TIFF image, convert to a CMYK profile, apply some adjustments (like curves) directly on the CMYK channels, and then save the output as a CMYK TIFF file.
Hello Pragomer, there are some options to convert from rgb to cmyk on Linux. Of course there is no native option in Gimp but alternatives are from good to excellent. I work with printing services (http://www.acpack.es/, http://www.andurina.com/) from a long time and I had no problems sending cmyk files from linux.
The first method is using an external application as Cyan
I also checked out, that Krita can convert it to CMYK, but after that it looks totally the same (what cant be, right?)
As far as I know it depends on the colors in the image. It can look the same but with some colors it does not. I remember flyer I made years ago in RGB and the text was in a yellowish/golden color. After converting it to CMYK the text had a more neonyellow color.
You said that you own photoshop so you could just test it. If it looks the same there krita converted it correct also and you can deinstall photoshop
