Discuss the different plastisol screen printing inks and curing methods on the market. Share tips on getting the best results with the different ink manufacturers.
1 - is this system 3 inkgoing to do the same job? same quality? cures the same way?
2 - do i NEED to use that printing medium or is that just an optional thing? is it recommended?
3 - In future when i look for inks for t-shirt printing, what exactly do i look for? if it says acrylic ink is that it? or is there more that makes it suitable for screen printing onto t-shirts?
That's a graphic ink (i.e. for paper, wood, etc.). It's not intended for textiles - it's not washfast. If you're printing on t-shirts do not use acrylic.
You can also get textile printing base, to which you add pigment (not acrylic paint).
If you're using bases you need to make sure you don't mix them up.
what if you accidentally used speedball acrylic on a shirt? how long would it last in the shirt? is there anything i can do to encourage it's longevity? DOH!
