I'm glad the masks are working out OK. What I do on the edges is bend the paper down a bit. Itr also helps to use 24 pound bond, or some other paper that is stiffer than the usual copy stuff.
Well, Hallelujah, I finally found all the right words to say and the cables to run to all the right spots, and the decals are printed with the ALPS. It's a neat printer, but it's also cranky. You never get something for nothing. I also have to admit that I spent some fair amount of time getting smarter with CorelDraw. If AutoCad would handle colors as well I'd never go near Corel.
Here is a jpeg of part of the sheet. You can't see the white outline on the reg numbers too well but they are there. I hope I did them wide enough. It's a judgement call because I think the effect of the white border has as much to do with the contrast between the white, the light blue of the paint scheme, and the black of the letters as it does the actual width of the white. The big 2's are because I found a picture of the airplane at Duxford in 1937 with that number, and I like it.
