Adding Puff to your ink

Printing white ink is the hardest ink to print.  On t-shirts you end up having to do two passes while doing a partial cure between passes.  This ensures you get proper coverage.  Unfortunately this also adds a lot of ink and can make the garment heavy. 

On Can coolers, it is not that feasible to print 2x and cure, so most companies add a little puff to the ink.  Puff is a chemical that literally makes the ink “puff up”  so it stands up.  You can add a lot of puff and come up with some pretty neat effects.
