Professional Screen Printing

What is the best screen printing ink that last the longest?

I heard versatex is really good and a new ink aquatex is good too. What is the best ink for quality of professional screen printing? I am a DIY screen printer but just started up.

Speedball is the most popular and obtainable screen printing ink brand in America. They have 2 types -- one for paper, one for fabric -- but they both work for fabric.
It is that the fabric ink is thinner, making it simpler for the rough texture of fabric to pick up details. (You use a higher mesh count to print on fabric ... so the holes in the silk are tighter, meaning the ink needs to be thinner). In my experience, all silk screen inks will be fine and wont wash off after you print on fabric, provided you waited long for the ink to dry.
