This is a set of two silk screen printing frames, A4 inner size, with 80 mesh or 100 mesh. Please specify whether you would like #80 or #100 in a message after purchase. This product is 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 suitable for printing on T-shirts, cotton bags, wood, etc. #100 is suitable for designs that have some fine lines or patterns, and can also be used for printing on T-shirts and cotton bags, but is more suitable for printing on materials with a relatively smooth surface. 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 films with your home inkjet printer. Silk screens can be exposed using sunlight, and you can easily print original logos, etc. with DIY, so please give it a try. How about making your own T-shirts, printing a small design for gardening, or printing shop merchandise? 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 ultraviolet light.

If you are unsure about exposure, we also sell test screen meshes, so you may want to try them out first before considering purchasing the actual screen frames. If you have any problems with exposure or printing, please feel free to ask. #silkscreen #stencil #screenprinting #tshirtprint #original #screen shop
