Carbon steel doctor blade is our basic, but very commonly used, type of carbon steel used at printing houses worldwide. The base steel material is made from genuine high quality Swedish steel. Together with our Swedish raw material supplier and end users, the doctor blade was produced to improve production quality, blade lifespan and to increase machine speeds. This thanks to the increased amount of carbides/µm² in the steel microstructure, compared to cheap and low quality carbon steel.

700 series is our ceramic coated doctor blade, developed by combining our unique surface grinding and special surface treatment technology. This improves the coating adhesive bond and wear resistance compared to existing coated products. It can even be an alternative for PrimeBlade® 900 Nano I blade users, especially for rotogravure printers.
The high grade steel together with the special ceramic particle surface coating technology gives a very low doctor blade tip contact friction, enhanced lifetime, and gives an extraordinarily clean wipe. It reduces the brittleness and cracking risk in the ceramic coating area, and lessens the risk of blade damage due to mechanical impact. Also, due to the refined steel and extra fine ceramic particles used, it reduces the ink contamination that causes higher wear on chrome cylinders.
