Hello all, I use International Coatings 700 series inks. I'm very new to this and have only worked with 100% cotton and 50/50 blends. A potential customer asked me if I did 100% polyester jackets? Would the IC 700 series inks transfer and cure properly on these? I emailed IC this same question but have not heard back. Thanks

What color ink and garment?

The dye in polyester has a tendency to bleed into the ink. Unless printing on white garments, you are better off using a low bleed poly ink.

Hi Gubby

We used to rep ICC Ink; not sure if I'm still qualified to assist.

700 Series is their general multipurpose plastisol line.
In that series is the 741 Ultra low-bleed white that can be used as a base layer on the poly jackets your client is asking about:

If the jacket color is dark and potentially will bleed, ICC has a barrier layer ink (so does Rutland and Union, too.) called 7040 Blocker Grey:

If you underlay with either of these, make sure you don't overcure when you flash or the topcoat layers may not bind well to the layer below.
Ask your customer if he has a test example of the poly jacket type to be printed for testing.
They can vary (i.e.-waterproof coated?) so clients will often respect your wish to confirm ink performance.

If you're unfamiliar with dye migration that can occur when printing poly garments, here is a great explanation by one of my favorite industry vets, Mike Ukena of Union Inks:

Happy trails!
