It's simple to screen print on paper or cardboard, and it's the perfect material for hand printing paper bags, handmade cards, and artwork. The kit includes a wide squeegee, a palette knife, a brush, drawing fluid, and a screen block. To create a silkscreened paper artwork, you'll get four primary acrylic colours and print gel. The Block out should be left a minimum of 72 hours to dry. It is imperative that a test then be performed on an area of the block out, rubbing it with a damp cloth or finger, to make sure it has cured. If some colour comes up, leave it for another day before testing again. In some climates it can take many days before the block out is cured so that it will not move when washing out the drawing fluid.
