The printed cut-out was soaked in water for 15 minutes to separate the cellophane film from the paper. My deduction proved correct as the print was made onto the cellophane film instead of the paper and thus the Canon Selphy postcard print works exactly like a regular water-slide decal.
The main drawback I conclude is that the CMY print cartridge of the Selphy printer does not print black - making the darkest tones appear as a very dark blue. Needless to mention, CMY printing does not print white - which means that this will have to be filled in by hand. Considering the type of quality for that inexpensive cost of print and the added convenience of doing it from your home computer, I must comment that the result is still rather delightful. Do give this a try and let me know what you guys think.
Until next time...
