Simply fold and crease the screen about your product to be pressed, slip it within some parchment paper, and your good to go. Screen unfolds and opens, unlike sewn bags, to be easily and quickly, emptied, rinsed and re-used. UPDATE: I noticed a short while ago, as did a few of my customers, that steel screen absorbs and wicks up heated resins Lets imagine for a moment that your unpressed source material is a wax soaked sponge. Rosin tech works due to heat and pressure. The heat makes the wax mobile and the pressure squeezes it out of the sponge. When using parchment paper as your collection media, heat makes the resin mobile and pressure squeezes it out of your source material. Being that parchment paper is neutral and non-stick, it has no affinity for resin or anything else. So when you release the pressure some resin gets absorbed back into the source material and thankfully some stays on the paper, hence the need for multiple pressings, depending on source characteristics. What if we use the steel screen as an additional collection media? Using screen within parchment, the resin has a place to move to when heated. It gets wicked away from the source material, and not reabsorbed upon pressure release. Both parchment paper and resin soaked steel screens require some work to collect the oils after pressing. Parchment is labor intensive as we all know, but all the steel screens would require is a quick wash in high proof grain alcohol or 99% isopropyl. After a short swirl, they come out crystal clear, looking brand new, and ready to be used again. The alcohol now gets strained thru one of the screens and is left to evaporate. Initial comparisons of the two collection methods seem to suggest steel screen yields 10% to 15% more resin from equal amounts of source material. Stay tuned for updates and please share your findings!
