How do I avoid the white spots that pop up on my garment after curing?

Answer

This issue happens at times when using a white underbase ink that contains a blowing agent. The blowing agent helps improve opacity and control dye migration. However, the blowing agent contains microbeads that inflate when cured, and some may pop, leaving a hole in the inks printed on top. To help mitigate this issue, use a quality white ink that does not contain a blowing agent, or flash the white a little longer to get the blowing agent to begin puffing earlier. Over-curing the ink may be another cause for the popping as well.
