Currently my design has 78 DPI, so I need to raise it. Is there an easy way to do this?

I learnt this the hard way, my mother works at a printer, so I have free access to thier printers, so I made some posters in the web-standard (72 dpi), and the result made me almost cry.

Unfortunally, yes, that's what I'm saying. Since the picture gets bigger (more pixels) but there is no new color information, I'll try to explain it in pic's :
The original pixel:
The pixels you get when you change the DPI (there is four of them, but they all have the same shade of green, so they look like one big block. thus making the image look pixlated.):
The pixels you want:
Very crudley done (I'm at work, with only paint at my disposal). Hope you get the picture anyway.

What you can TRY is get a program like Paint Shop Pro (version 6 or better) or Photoshop, and try either a bicubic resample or a billinear resample when you resize the picture (change the DPI). This is not a catch all solution, and will certainly not ALWAYS work, but I've had SOME luck with it, so it can't hurt to try.
But yeah, anything that has to go to a printer (t-shirt screens, photos, whatever), make sure you do your work in at least 300 dpi.
