Apologies for the cross-post from
my Project Announcement, but I think this is relevant here...
While working on the artwork for my Gauntlet Legends cabinet, I ended up needing to blow up some really dinky artwork (588x250) to something big enough to print at 240dpi (9000x3840). Needless to say, I also didn't want it to look like pure crap.
Ran across
GREYCstoration, which is an app that specializes in image restoration. It specializes in image restoration via denoising and interpolation, and does an
awesome job. If you're doing any sort of bitmap restoration,
this is a tool you want to check out.
After running my dinky artwork through and blowing it up, I ended up with something that looked far superior to what I'd started with. Was actually happy enough with the results that I had it sent off for printing this morning.
I know that ideally we'd love to have vectorized artwork for everything, but if you're stuck having to deal with bitmapped artwork, I'd highly recommend adding this to your arsenal of tools...
