|A steel blade set up to print a copper roller (chrome faced) Here, we are checking the angle of the blade so that we can mimic it on the second press.|
Although this set up (using a steel blade) is working, we fear that it is contributing to the increasing damage that is frequently appearing on the chromed surface of these engraved rollers. Also, the steel would cause havoc with our newly laser engraves rubber sleeves, so over the course of the project, we have been testing alternatives.
|A selection of the blades which we have tried. On the top, is the steel which is currently used. Below are a selection of commercial alternatives (other metals with various angled edges and coatings), plastics, rubbers and urethanes.|
