Why doesn’t the ink adhere to the garment?

Though under-cure can be the cause, the reason I didn’t include this with question #1 is because usual suspect in this situation is incorrect ink selection. Different substrates require different ink or ink preparation in order to ensure good adhesion.

This question is answered on a case-by-case situation, but the most common materials in which poor adhesion will occur are Nylon and Nylon Lycra. It is best to call your ink manufacturer directly for recommended inks for the substrate you will be printing.
