The thermal acetate carrier is designed to work in conjunction with thermal copier paper and thermal copier machines. The carrier slips over the paper and helps aid it through the machine for a smoother and more thorough stencil transfer. It isn’t essential to have the carrier however it does make the process a lot easier. Available in packs of 5 and suitable for use on A4 thermal copier paper. Acetate carriers can be used more than once, typically until they become worn.
