<p>[QUOTE=&quot;tommyc03, post: 2726473, member: 17665&quot;]I probably could not word it correctly, but the BEP site does have some interesting information and I believe, some videos about parts of the process of printing notes. In many cases improper transfer of ink is/can be caused by a faulty &quot;Wiper&quot; blade that crosses back and forth against the print cylinder. It is very thin and extremely sharp and if not checked often enough, can get nicks in it that allow this to happen. We had the same problem in printing barrels for hypodermic syringes where I worked. They were referred to as &quot;Doctor&quot; blades. Even though the base for the ink is a pure as it can be, it has to be diluted to get the proper consistency to print properly and sometime stray foreign matter can get into the pumps that can cause these blades to get nicked. This is almost always the cause for ink smears and other spots. The alignment of the blade to the cylinder is extremely precise so as not to damage the cylinder.[/QUOTE]</p><p><br /></p>
