For this map? Nope, my old system couldn't handle the 1inch grid at 300dpi so I planned to just have it print out at smaller sizes instead (figured most ppl were going to use it for online table top). For online use at 72dpi, the varying quality isn't as obvious, thank god.
People who bought it for print tho, started blowing it up at 200dpi. It turns out, they really want their 1inch grids for play with token miniatures at their local gaming store. The good thing is that once printed, people will be looking at it from across a table so the edges won't be as obvious (hopefully).
The graphic assets were purchased for commercial use from a third party cartographer. Now, if I were drawing the elements from scratch, I'd have them as vector art to maintain consistency, but this is more a hobby and to give back to the community. They don't have color maps for RPG adventures besides black and white marker drawings and this would allow for better immersion during the game. The only way to make any real money off it would be to get hired by the publishers, which is not happening.
