Understanding the different types will help you choose the right screen printing emulsion to create a quality stencil for a quality job. Screen printing emulsion works much like plastisol ink. Just as plastisol ink cures when exposed to heat, emulsion cures when exposed to UV light.
In screen printing, there are three different types of emulsions, based on the photosensitizers used. Total Ink Solutions offers a variety of different emulsions for your screen preparation needs. When it comes time to choosing your emulsion type, there are many factors that can come into play, but you can create quality prints with any of the three types of emulsions.
SBQ-based and dual-cure emulsions can be trickier to work with because of their faster dry times, but the more difficult emulsions can reward you with a more detailed print. Higher mesh count screens require a less solid emulsion, while emulsions that are too thin will not properly coat lower mesh count screens, resulting in pinholes or other flaws in the print. And — as with most things in screen printing — the more you print and the more you experiment with different types of emulsions, the better you will get at determining which emulsions are right for different projects.
Anatol offers a variety of different exposure units to help you prepare your screens quickly, efficiently and with sharp detail. The chemistry of photopolymer emulsions make them great for fine details and half-tones. If you do not want to deal with the mess of applying liquid emulsion, a great alternative are emulsion sheets, also known as capillary film or direct film.
Capillary film can be exposed with LED exposure units or weaker fluorescent tube units. The most popular photo emulsion sheets are Ulano EZ-Film. No matter what type of silk screen emulsion you use, there are a few pro tips to getting the most out of your product. First, this screen printing supply item can be stored in the refrigerator.

This is also a dual-cure photoemulsion for plastisol ink. It very good resistance to plastisol inks, waterbased inks and solvent based ink. Excellent stability on the screen. Suitable to work with any kind of light source.
Easy reclaiming of the screen. Easy to use. Sensitize with diazo, add a small amount of water to the bottle with diazo in in order to dissolve the powder. The emulsion includes the required sensitiser and works well for beginners and advanced printers. Screen Chem Catalyst - makes emulsion permenant. Add a small amount of water to diazo-sensitiser and shake well. Since it is a polymer emulsion we recommend you work in an area with low to little light, not under a direct light or in sunlight.
We recommend you always degrease the mesh. Plastisol ink can work with all the emulsions Ryonet offers. Emulsions for Water-Based and Discharge Ink :. Plastisol Ink :. Is your darkroom light safe? Do you have an exposure unit with a timer and vacuum lid? Is your washout booth in the same room? If you work in a space that doesn't permit any light to enter and you have the right equipment, you can use either presensitized or diazo mixed emulsions. If you're working in a spare bedroom, bathroom, garage, or a space where there's a good chance light may enter at some point of the process, you'll want to stick with the diazo mixed emulsions.
It's also a good idea to use diazo emulsions if you're using a bulb or an exposure unit without a lid since diazo slows down the reaction of curing. Insider Tip : If you're using your backyard as your washout booth, try wetting your screen with a spray bottle before you go outside. By wetting the screen, you'll help prevent the emulsion from cross-linking with the screen before you're able to wash it out.
It's also a good idea to put the screen in a black garbage bag when bringing it outside to further prevent the emulsion from cross-linking.
