Do you like graphics? Yes. Well this is for you. I came upon this transfer paper quite by chance, it is waterslide decal paper. Print with your inkjet printer and produce transfers just like photographs. To overcome the water solubility of the ink the paper is simply sprayed with two or three coats of acrylic spray after printing to seal the image. Then simply soak off the transfer in warm water (when the acrylic varnish is dry) like you used to do with Airfix kits.

There are two types of paper: clear and white, both in letter size (8"x11"). If you can put it on your computer screen you can put it on your model (or anything else for that matter).

I got three sheets from Ebay.co.uk for a couple of pounds but I know you'll find it elsewhere on the net. I've seen it in larger sizes too.

Can't do graphics? Just use Word Art feature in Microsoft Word as above or if you've got Photoshop how about something more challenging using Photoshop Actions. Or how about some carbon fibre ailerons on your model?
