SolarFast Questions about negatives
  • I am just trying out SolarFast and I want to confirm:

    When I make an inkjet transparency on my computer it should be a 'negative,' meaning darks and lights are reversed, correct?

    When I do my exposure, I should have the printed side of my negative facing up, not against the surface which has SolarFast painted on it, correct?
  • These are both right. The dark areas of your negative create light areas on your final product. So you need a negative, as opposed to a positive like you would use to make a screen for screen printing.

    The printed side of your negative is not waterproof and can smear if you place it against wet solar fast. The backside is smooth and waterproof, so you can use it over and over. You can tell the printed side because the coating that accepts the ink from the printer is slightly tacky.
