A dirty scoop coater, or one that has begun to show wear and tear due to use, will interfere with the smooth line created by the edge of the coater, which in turn causes lines or other unevenness in the emulsion as you coat your screen. If lines or imperfections appear in your emulsion as you attempt to coat your screen, take a look at your scoop coater. Lines or flaws in the emulsion during coating If you are still struggling to create, expose and reclaim screens, here are some additional troubleshooting tips to help you address common screen printing issues with your emulsions. In a previous blog, we covered some common exposure problems and how to troubleshoot them. Ulano Orange reduces stencil-making time-in coating (because of its high viscosity), drying (due to its high solids), and exposure (due to its high photo-sensitivity despite its “masking color.Problems with your screen printing emulsion can be especially frustrating: You can’t turn out a good print if you have any problems with your screen’s emulsion or exposure. Ulano Orange stencils are durable, will not become tacky under high humidity conditions, and have excellent wet strength and exposure latitude. Ulano Orange resists plastisols, most washup solvents, and some water-based textile inks, and it is easy to reclaim. Its high solids content (44 – 46%) results in better mesh bridging and edge definition, and fast drying. Ulano Orange has high viscosity (6,000 – 8,000 centipoise) that improves control when coating screens by hand and makes it a good choice for coarse mesh. Despite its anti-halation color, Ulano Orange is ultra-fast-exposing! It is perfect for shops with high stencil making throughput, as well as shops with fluorescent tubes or other low-intensity light sources. With Ulano Orange, it is possible to use less costly white mesh without the closing up of fine lines and details. It is formulated with a “masking color” that reduces light scattering-the major cause of loss of resolution. Ulano Orange is a ready-to-use SBQ-photopolymer direct emulsion formulated for imprinted sportswear printing. Ulano Orange reduces stencil-making time-in coating (because of its high viscosity), drying (due to its high solids), and exposure (due to its high photo-sensitivity despite its “masking color.”
