I wanted to update this thread with some information I had recently. I was experiencing serious issues with a book project I’ve been doing in ProCreate - the psd files exported from ProCreate just did not look even remotely the same on my computer as they did on the iPad (strong loss of contrast).
I wrote to the ProCreate team and shared one of the files with them.
It turns out, the CYMK profiles used by ProCreate do not compare with the CYMK profiles installed on a computer (the ones that drive the printers) and my files were set up in one of ProCreate’s new and shiny CYMK profiles. There’s also no way to change the color profile of an image in ProCreate once you’ve decided it at the onset, so I cannot convert those images to a RGB profile to export the PSD files without damage.
I have a very lengthy workaround that allows me to preserve the image quality, although it will take me at least 10 hours to export, re-convert and color balance the images of that project. Obviously, there’s no way I can share them directly from ProCreate with the art director: he will end up with the same issue on her end: not pretty.
This confirms the point I mentioned above: ProCreate is not really a professional tool, and if you’re dealing with a team including an art director, book designer, pre-press expert in printer on the other side, you’ll need to anchor to Photoshop at some point or other.
It remains a great digital painting tool, and as long as you’re not dealing with transferring your files for print, it’s great to work with. If you need to create files to spec, you can still work in ProCreate, but you need Photoshop at the end to finalize.
