That provoked some research.
Several websites have similar instructions:
- Step #1:
- Design your decals using any graphic software program. (Use 8 1/2 " x 11" sheet BEL INK JET Decal Paper or cut sheet into half if desired.)
- Step #2:
- Set your printer as follows:
Resolution = Best
Paper = Photo Gloss
(Print your decal on the glossy side of BEL INK JET Decal Paper.)
- Step #3:
- Spray your printed sheet evenly with Krylon Acrylic Crystal Clear High Gloss spray until the sheet has a shine (2-3 coats). Allow 30 to 60 minutes to dry and set. (This product is available at any craft or hardware store such as Loews, Home Depot, Ace Hardware, Walmart, etc. Any acrylic clear coat spray will work.)
- Step #4:
- Cut out your image using a standard pair of sharp household scissors.
- Step #5:
- Place decal into a cup of clean water for 45-60 seconds and remove when the thin decal film begins to slip along backing.
- Step #6:
- Apply decal to clean surface.

Some folks talk about a clear coat after the decal is set. Micro-Mark has a page with the full sequence.

Here is a model train builder's page full of procedure:

And finally, here is a guy who specializes in decal building. He uses a Kodak First Check Digital Proofer. The Kodak printer is a very specialized printer which uses water-proof ink that adheres to decal paper.

Alps Electronics stopped producing Micro Dry Printers for sale on the open market a couple of years ago. The First Check is actually manufactured by Alps for Kodak and uses the same technology as the Alps MD Series Printers. We will be using a combination of Alps and Kodak inks to produce our products. Alps consumables will be available for a quite a while according to the Alps Tech Department. For anyone wanting information on these printers check out Kodak Polychrome Graphics.
That ought to be enough pointers for anyone interested in this thread to find more info. There is talk of waterproof inks and ALPS printers and lots of variations on the paper for those who want to delve further.
The question I have, which would have to be figured out with some testing, is:
Once you print the decal, put a couple of light coats of Krylon on the decale, cut it out, clean the surface and prep it with a fixative solution, slide the wetted decal on and smooth it with decal set and let it dry--can you spray a light coat or two of clear Krylon to firmly seal and protect the decal and then go shoot the clear dope and remainder of the finish over the Krylon?
If so, one should be able to get a pretty clean result.
As one of the decal mavens puts it: "The art of decaling is making it look like you did not use any decals!"
I can see it now.
In six months we'll see a flurry of stunt models with lots of detail markings all over the airframe.
I always thought it would be a good idea to put a tiny stencil/block lettering note next to the filler and vent tubes.
"Service this aircraft with fuel containing no less than 25% pure castor oil and no more than 15% nitromethane. Fuel capacity 6 Oz."
Just a thought.
