If you’re still wondering whether you should be designing in RGB or CMYK format when it comes to print on demand products, then this video has the answers. W
Theres no way to convert a 3 channel curves layer to a 4 channel curves layer. Because they adjust differnet things. See CMYK is the inevrse of RGB so even the curves layer is now totally different. * Now you can be smart about this and merge down the adjustment before conversion.
Sure there are conversion algorithms that would find a closest match. If you're wondering if there's a matching pair of algorithms that allows one to convert back and forth between RGB and CMYK without losing data I'd guess no but I'm not sure about that at all. –
When you work in RGB and then convert in CMYK, you often have to make some tweaking on some colors because the automatic conversion (like changing the color mode) sometimes makes the colors even more dull than they should be: RGB. Same RGB converted to CMYK (automatic conversion) Same CMYK Colors as above but tweaked to be a bit brighter
I would follow a kind of brute force attempt and: set up color management, then enter the CMYK values you want to get and see what happens. You might need to go a little back and forth between the RGB and CMYK view in the color panel (don't change the document color mode yet). When you get the color, rasterize in the resolution you need.
