Hello everyone! I have a quite big problem with white canvas shoes. I'm using the Kornit fixation agent "50-FIXA-3311" and got brown stains allover after the drying process. Does anyone have a solution for me? Many thanks in advance!

There can be two problems:
1. chemical impregnation of the canvas reacts with the spray.
2. high drying temperature

You can try spraying some Hydrogen Peroxide on the brown stain part, then dry it again quickly. This usually took care of the problem for me on white/lighter fabrics.

its the pre treatment, lower your drying temp but do more drying cycles if that makes sense.
