Lazertran Waterslide Decal Paper for Inkjet printers . It does not need to be sprayed with a cover coat like other inkjet waterslide decals but magically the inks become waterproof after 30 minutes allowing the decal to be put in water without the colours washing away. It is an egg shell white decal that can be made clear by the application of any oil based varnish. We find oil based polyurethane works well. A4 (297 x 210mm)
