I've been using Corel Painter 7 to digitally create my artwork, working onto Riff files, at 72dpi, but when I try to print them out, they are terribly blurry, and I've been informed that it's because my resolution is too low, and should be 300dpi.
I guess I have three questions, first - is there any way to get a 72 dpi image printed out, looking as good as it does on the screen - i.e. using a specific file type?
Second, is there any way to increase the resolution, maintain the same image size and not lose any quality?
The other question is - is having the image at 300dpi in the first place the best way to do it? This has been suggested to me, but I tried opening a 300dpi file that would be roughly A4 sized once printed, and it was enormous, far too large to realistically draw on using Painter - so how do people do it?
Thanks for your help!
