The new iPad Pro seems to be what I have wished for and I can go all digital when I travel, leave paper behind and draw directly on the screen. Great - but newspapers and magazines are still printed on paper and they demand exact measures in millimetres - and also the exact print resolution. So how do I change that on an iPad to prepare an image for print? Let alone adding a CMYK-profile, but I guess that is too much to hope for. But if I can at least change the resolution of an image to 300 dpi (or ppi or whatever is the correct abbreviation) while keeping the exact physical measurements, it would be great.
