![]() ![]() I use Speed Cleaner first and try to remove it:Ī good scrubbing usually does the trip but sometimes I use distilled white vinegar and the Magic Eraser to help. Once the emulsion is gone sometimes I still have stubborn ink left behind: Once you see the emulsion start to dissolve away you can spray with water and continue scrubbing until the emulsion is completely gone: I take a paint brush and coat one side with the remover and then flip the screen over and coat the other side as well.Īllow the emulsion remover to soak in exactly 1.5 minutes and then scrub with a nylon brush or scrubber. I use Diazo Emulsion Remover to dissolve the photo emulsion from the screen. Any ink or screen filler will keep the emulsion remover from working. I also use distilled vinegar and a Magic Eraser for stubborn stains. So, if you are finished with an emulsion design and want to reuse a screen here is how you remove the emulsion:īefore I remove any emulsion I remove any excess ink or screen filler that was used to patch up the screen. I keep the following on hand to clean my screens: Note: I tend to use Yudo screens to screen print because they are flat and don’t take up any storage space….however the there is no protection on the sides against flinging your ink out across the table like a larger frame would have so I have to be super careful. Speedball’s Diazo Photo Emulsion & Sensitizer offer professional-grade results and remove the need for expensive equipment and darkrooms. ![]() Only emulsion remover can remove the design so that the screen can be reused with a different design. The photo emulsion method of screen printing allows artists to create a photographic stencil featuring highly-detailed images. The ink can be washed away after use and the design will not wash away. Photo emulsion allows you to screen print very detailed designs over and over again. If you print out a design on transparency paper, place it on top of the screen and expose it to light….the photo emulsion will expose and become permanent on the screen except for where the design blocked out the light. After screen printing the ink can be washed out of the screen and the contact paper still stays in place and can be reused for multiple prints.Įmulsion: Photo emulsion is a substance that you apply to a screen and let dry in the dark. Here’s the difference:Ĭontact paper: I hand cut a design into adhesive paper and apply it to the screen. You can store dual-cure in similar temperature settings as photopolymer emulsion.I get so many questions on how to clean a silk screen I thought I’d do a tutorial on it! There are two types of screens that I use over and over again: the contact paper stencil screen and the photo emulsion screen. Adding the diazo shorts the shelf life to about 4 - 6 weeks. Prior to adding the diazo, unsensitized dual-cure emulsion has a shelf life similar to the Photopolymer SBQ emulsion (described above). Double check for any visible growths or strange smells when you open the container if you use a “bargain” brand.ĭual-cure emulsions require screen printers to mix in the diazo sensitizer prior to use. ![]() ![]() Quality emulsion brands like Ulano and Lawson include a fungicide to combat this possible problem. Lastly, liquid emulsions run a risk of developing mold and mildew. After stirring, make sure to let all the air settle out before use. Your goal is to evenly distribute the solids back into the liquid. While not necessarily a problem, it does mean you have to vigorously stir the emulsion for several minutes prior to use. If you have ever stirred emulsion that has been sitting for a while, you will notice all the particles at the bottom and the liquid on top. When liquid emulsion sits on the shelf the solids fall out of suspension and settle to the bottom of the container. If you are going to store liquid emulsion for a while, placing it in a refrigerator can work but just make sure it does not freeze.Īside from the temperature, the time it sits undisturbed has an effect. Emulsion is most stable when stored at room temperature (somewhere in the mid 60’s to the upper 70’s degrees fahrenheit). Photopolymer can also get too hot during storage, causing the photosensitive chemicals to react poorly.
