All I said is that I find it repulsive when people side with corporate greed-machines, that is not an insult, it's an opinion I'm entitled to.

I haven't a clue what the maximum PPI for a specific program is, but providing you know the maximum output dimensions of each program, you can work it out by dividing that resolution by the amount of DPI the printing press requires.  Whatever amount it comes to, that's how many inches you have to play with, at least I think that's how it works, I'm probably wrong though, so don't quote me on that.
