The difference between Murakami Thick Film and Aquasol HS is what are you printing. If you are printing High Density Inks and need vertical sharp prints with super sharp corners Thick Film is the way to go. If you are just printing Gels, Glitters, puffs, etc then Aquasol HS is a less expensive solution. It coats wet onto wet, its the dry time that is very different. I can make a thick film screen in about an hour with a good drying oven. Aquasol HS is overnight with a fan on. Both have to be dry to use propertly.
