This is a set of two silk screen printing frames, A3 size inner dimensions, with 120 mesh or 150 mesh. Please specify your preference of #120 or #150 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. #120 is suitable for printing designs with coarse gradations, thin lines, and relatively small characters. #150 is suitable for images with fine halftone dots and small characters. It can also be used for printing on paper instead of fabric. Both #120 and #150 are suitable for printing on smooth surfaces. Please note that if the surface of the printed material has large irregularities (such as canvas with clearly visible seams), the ink may not reach the recessed areas, resulting in a blurred appearance. The photosensitive emulsion will be applied and thoroughly dried before shipping. 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. Mesh count: #120 or #150 Normal (coated with water-based and oil-based ink photosensitive emulsion) Exposing film: 2 sheets included Outer dimensions: Approximately 550/450/18mm Inner dimensions: Approximately 480/380mm Other: Inkjet film, instruction sheet for sunlight exposure, screen film strengthener *The photosensitive emulsion hardens when exposed to ultraviolet light. Please be very careful not to expose it to light before exposure. If you are unsure about exposure, we also offer 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 #remake #usedclothing #screenmaker
