Dual-cure: Dual-cure emulsions combine diazo and photopolymer emulsions.Pure photopolymer emulsions are usually the most expensive choice. Because pure photopolymer emulsions expose so quickly – usually in just a few seconds – it helps to have a reliable exposure unit with an accurate exposure timer. Pure photopolymer emulsions have long shelf lives, but most are not very water-resistant, so they may not be as well suited to water-based inks. They are pre-sensitized, meaning they are ready for use right out of the package with no mixing or other preparation required. Pure photopolymer: Pure photopolymer emulsions expose much more quickly than diazo emulsions.On the positive side, diazo emulsion is often the most affordable option. However, diazo emulsions are less sensitive to light than other types of emulsions, and thus require longer exposure times.
Diazo emulsion changes color during exposure, letting you know visually the degree to which your stencil is exposed. Diazo: Diazo emulsion is a good choice for novice screen printers because it’s easy to use.There’s a seemingly endless variety of emulsions available for screen printing, but three of the most common are: The most obvious factor that goes into your stencil creation is your choice of emulsion. Here are some factors to pay attention to! Choosing the Right Emulsion If you’re looking to create finely detailed screen prints, you need high performance stencils.
