This is a set of two silk screen printing frames, A4 size inner dimensions, with either 80 mesh or 100 mesh. Please specify your preference (either #80 or #100) in a message after purchase. These products are coated with a photosensitive emulsion that can be used with both water-based and oil-based inks. #80 is suitable for designs with few fine lines or patterns, and is ideal for printing on T-shirts, cotton bags, wood, etc. #100 is suitable for designs that may have some fine lines or patterns, and can also be used for printing on T-shirts and cotton bags, but is best suited for printing on materials with relatively smooth surfaces. The photosensitive emulsion will be applied before shipping, and the frames will be thoroughly dried before being sent. This product also includes inkjet-compatible film so you can print your film positives using your home inkjet printer. Silk screens can be exposed using sunlight, allowing you to easily print original logos and designs with DIY methods, so please give it a try. How about making your own T-shirts, adding a design to your gardening projects, or printing merchandise for your shop? Mesh count: #80 or #100 Normal (coated with water-based & oil-based photosensitive emulsion) Outer dimensions: Approximately 360 / 300 / 18mm Inner dimensions: Approximately 312 / 252mm Other: Inkjet film, instruction sheet for sunlight exposure, screen film strengthener *The photosensitive emulsion hardens when exposed to UV light. Be very careful not to expose the frames to light before exposure. If you are unsure about the exposure process, we also sell test screen meshes, so you may want to try those first before purchasing the main screen frames. If you have any problems with exposure or printing, please feel free to ask. #silkscreen #stencil #screenprinting #tshirtprint #original #screen shop
