This is a set of two silk screen printing frames, A4 size inner dimensions, with 120 mesh or 150 mesh. Please specify whether you would like #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 items with fine halftone dots or 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 before shipping, and the frames will be thoroughly dried before being sent. In addition, this product includes two inkjet-compatible films so you can print films with your home inkjet printer. You can make a screen with sunlight, but try exposing it for a slightly shorter time than usual. Be especially careful when exposing #150 to sunlight. You can easily print original logos, etc., with DIY, so please give it a try. Mesh count: 120 or #150 normal (coated with water-based & oil-based photosensitive emulsion) Outer dimensions: Approximately 360 / 300 / 18mm Inner dimensions: Approximately 312 / 252mm Other: Sunlight screen making explanation paper, screen film strengthener *The photosensitive emulsion hardens when exposed to ultraviolet light. Be very careful not to expose it to light before screen making. If you are unsure about screen making, we also sell test screen meshes, so we recommend that you try them first before purchasing the actual screen frames. If you have any problems with screen making or printing, please feel free to ask. #silkscreen #stencil #screenprinting #Tshirtprint #original #remake #usedclothing #screenmaker
