I want to do some color printing just because I'm worried that materials won't be available in the coming years. I understand that Kodak's paper is only available in rolls right now, whereas Fuji has some paper available in sheets (does anyone else make color paper?). On top of the Kodak paper being available in only rolls, I have heard that color paper in general is optimized for digital printing. But I don't understand what this means. What is different about a paper optimized for digital printing vs. enlarging? How do digital printing machines work? Don't they still use R G B light? Why wouldn't they just design the printing machines to work like a negative? How big of an issue is this supposed "digital optimization" for the darkroom worker? How does it affect film choice? Overall, how much worse is it now compared to the absolute heyday of color printing (which I'm guessing was the late 90s)?
