Hi Steve, To date my only experience with laser decals is a friend mentioning his wife, who's a teacher used it successfully on school projects,
I didn't know it was available ! - my home laser is a recent purchase whose full range of properties need to be explored.
A quick web trawl found the video below showing a white 'background' paper is available !
plus no spraying waterproofing lacquer before printing as with ink jet.
Colour saturation mentioned in the video may be an issue?
my A4 'home' laser doesn't quiet have the colour depth of my old ink jet when it comes to printing colour photos,
playing around with settings may improve etc.
Have to say ink jet waterslides did remind of the old rub downs -
their colour depth, glossy sheen and slight material thickness (small raised step around the edges) was just like Chromatec.
But we've moved on to the laser which has been a revelation !
it fires straight up, prints multiple pages instantly and none of the cartridge faff of the old ink jets.
Paul.
