Hello,

when i am working in RGB the the colors of image looks good, and they are the same whan i save ij JPG, Tiff, etc. but when I am working in CMYK and when I save a file in JPG  the colors become highly saturated or even invert ( when a save a file as TIFF), what settings do i have to change? 

I thoght that when I convert RGB to CMYK I just have to go to Edit->convert to profile-> flatten all the layers and that's it, but as I saw it's not enough

What should I do?

Hi

There are differences between RGB and CMYK.

Im afraid we can hardly get a "lossless" conversion from RGB to CMYK, especially if saturated, bright colors are involved that cannot be mixed from the component inks with limited gamut.

Refer to the link below to learn more about RGB and CMYK:
