Back a few years ago when I was in school, I learned that CMYK images are for print and RGB images are for the web.
Now after a few years of working on my own, I have an actual job. (Yay me! may it last more than few months my city sux for creative jobs.)
There have been quite a few graphic designers in here over the years, it seems as though they have been using .jpg and .png for print, and no one is complaining. I am really more curious, I guess. Was I taught wrong, or has the world moved on and the rgb color space works just fine for digital printing. Or is the printing machine --giant color copier-- compensating somehow?
The images look fine to me, you definitely used to be able to tell when a jpeg was used in a print project. I am not talking about DPI and PPI. I mean the artifacts and the weird smudgy look.
I tried a web search but I didn't find too much recent discussion on the topic.
Modern digital printing processes have evolved to deal with RGB much better than they did in the past.
That is more or less than I thought
