I wanna to buy some water based screen printing ink. I'm planing to print on different color t-shirts. The problem is for what I'm planing to do, I'm not sure which one to buy the Transparent or Opaque ones. It said on the site that Opaque is better for screen printing on dark color shirts, but can I use the transparent on let say a darker color shirt? By the way I'm looking at the EnviroLine Water Based Inks. Any help would be greatly appreciate!!!
Also I'm planing to print some t-shirt for my friend, wonder if there is any kind of supply needed, he already has some Wood Screens and Squeegee. Any other supply you think I'll need?
