USE WITH: Screen Printing InksUSE ON: Natural or synthetic fabric and paper, vinyl, metal and leather Jacquard's Puff Additive is exactly what it sounds like!Take your screen printing ink, throw in a bit of Puff Additive, mix thoroughly, print your design like normal, add a little heat with a heat gun - or in your oven - and watch the design slowly rise.Is it magic?Probably.Is it fun?Definitely!Pot life of mixture is indefinite. Once puffed, the print is washfast and dry cleanable.We've tried this particular additive with Jacquard's Screen Printing Ink, Versatex Printing Ink, and Speedball's Screen Printing Ink.While it does work with each type, the results are less than favorable with both Versatex and Speedball's products. With that in mind we would recommend either doing your own testing before committing to a large project or to just stick with Jacquard's Screen Inks for best results.
