Hi! A few tips on using Sapphire inks for screen print process:
• When using Sapphire inks for screen printing, you need a slower thinner than that you use for pad printing and you need it in lesser quantities. You want to add 3-5% of thinner to start and then see if you need more. For instance blue colors will most likely be fine but some red colors will require more thinner. High density colors will always require more thinner.
• Use S3 screen thinner, it will prevent your screen from “locking.”
• To increase ink opacity use the widest mesh appropriate for your artwork.
