I use to use printers plate also but they closed the news paper here and it is fifty miles away in any direction! Besides, with printers plate you are limited to size. Flashing is in a continuous roll up to twenty feet and in a number of widths! The only back lash is that it wants to unroll and damage itself. It is hard to keep it from unrolling without damaging it, It can be done, just a PITA! Kinda like a watch spring! BOIOIOIOIONG! If you ever let it get away from you, it will PI-double-is you off!
Also, there is no ink to clean off just a very light mist of lubricant. Rubbing alcohol works nicely.
