How Do I Test to Make Sure My Inks Are Properly Cured?

June 11, 2015 at 4:00 am 2 comments

We get this question all the time about how one can make sure that the ink is properly cured.  A “Wash Test” is the best method.

Here’s how to do it:  Take a sample print, cut it in half, and wash it 3 to 5 times in a conventional washing machine with 3 pairs of (old) jeans or towels.

Set the washer for ‘Hot Wash/Cold Rinse’. Set the dryer for ‘Cotton/High’ and dry for 30 minutes. Complete 3 to 5 wash cycles and compare the “washed” sample to the “unwashed” sample. If you see cracking of the ink film or ink loss, your inks are likely under-cured.
