EMULSION Mesh is coated in emulsion before designs are burnt. Large shops have automatic screen-coating machines in their setups for consistent results, whereas small- and me- dium-sized shops often apply emulsion by hand. For manual application, you need a scoop coater, a stirring stick, and a steady hand. The best method to prepare the emul- sion is to stir it well with the stirring stick, then let it sit, so any trapped bubbles escape. This prevents pinholes, which occur when dust, debris, or air pockets are trapped in the mesh before or after applying emulsion. For consistent coating results, Consilvio suggests choosing a scoop coater that is a good fit for the person doing the coating. There are single and dual-sided scoop coat- ers. The latter provide either thick or thin emulsion deposits based on need, making them versatile. Coaters also have either large or small troughs to coat different numbers of screens at a time. Instead of emulsion, some shops use capillary film to coat screens without wor- rying about waste, inconsistency, or dried- out emulsion. To use, after degreasing the screen, the film is applied and any excess water is removed. Once your screens are coated evenly, you must allow them to dry in a dark area so they are not pre-exposed to ultraviolet (UV) light. A drying cabinet prevents this. Dry- ing times will vary depending on the hu- midity in your shop and the thickness of the emulsion, but drying cabinets reduce the amount of time they need. REGISTRATION While waiting for your coated screens to dry, sources recommend preparing film positives with your designs using a large- format inkjet printer. The quality of your artwork is invaluable in this step. Each design on the film should be completely opaque and have the highest resolution possible. Landesman warns that film at- tracts lint, so it should be free of dust, fin- gerprints, and other unwanted marks to ensure the best possible print. The all-electric Anatol VOLT is designed to let you print with more consistency and reliability than ever before, making your projects appear as flawless as possible. And best of all, the VOLT doesn't require a costly air compressor or chiller. • 847-367-9760 Just plug it in and print. abra abra!
