After 10 years of being known as "DynaArt Designs" we have changed to "Pulsar". Our "direct etch" product - The Toner Transfer System , (or TTS for short) is a specially treated, letter size, light weight 5 mil thick paper that can run through any laser printer or photocopier without jamming. The printed image on the paper is simply ironed onto a blank copper board, placed in a tray of water to remove the paper and then into the etchant. The entire process takes about 3 minutes!
