I’ve been very lucky with the thermochromic ink. I got a very big discount from Blanken Controls, two liters for the price of one. That was just as well because my first attempt at screen printing has failed. I went to a workshop to get assistance. And after having obtained a screen with the right mesh size I was confident that things would go right. But there were some difficulties.
I want a big and perfect black square printed on the three colours of fluorescent fabric I’ll be using. Each colour representing a gas. I got the nice looking water repellent fabric from HaVeP. Unfortunately it also repels ink… It was hard to get an even print although I did manage to fill the area but it wasn’t even. The red fabric was most successful, it isn’t water repellent. But even there it was hard to get an even area.
I’ve taken some steps to improve the results. HaVeP have kindly send me orange and red fabric that isn’t water repellent. I’ve spoken to another graphic workshop who’ll help me with the printing of the black area. They seemed confident that this is possible and have all the right equipment.
