Custom Flex Doctor Blade Profiles

Profile 10
Custom Flex Profile 10 doctor blades are beveled and feature a fine tip allowing the blade to seat rapidly with a minimum of scrape. The beveled profile compensates for typical chamber and end seal distortions for a more effective wipe.

Profile 25
Custom Flex Profile 25 doctor blades have become the industry standard in flexography. Both sides feature a smooth round metering edge. The round edge is less expensive than precision-machined blade tips and skates over rough and delicate ceramic during press start-up. The extra smooth edge provides quick seating against the anilox roll surface.

Profile 50
Custom Flex Profile 50 radius step doctor blades, or lamella blades, have a reduced thickness wiping tip for applications requiring a very fine wipe. The contact area remains the same throughout the life of the blade, so ink film thickness remains constant.
