• I would like to know the general open time when using the screen printing inks. I think I will need the product "Screen Life" as
    I am having a difficult time with the open time. Could my ink be too old and viscose ? What is the shelf life of a pot once it has been opened?
  • Hello LH5,

    We usually don't give an exact open time for the screen inks as different weather conditions can really change that amount of time. Ideally it should be between 30-60min. Old ink will be shorter, and could probably use a little water. I personally prefer a consistency slightly thinner than the way JSI comes out of the pot. I like to add 1/2 a teaspoon of water to the ink that I put in the screen. This would likely rejuvenate your older ink as well. The older opened ink shouldn't be a problem as it has a very long shelf life, but it may be a little thick.

    Spraying some water through a mister onto your screen can help and screen life can extend the open time to over an hour if used properly.
