Composite Doctor Blades Replace Steel in Sheetfed Offset Coating Applications

blades In this challenging economic climate, sheetfed offset printers are turning to composite doctor blades in their in-line anilox tower coating units to ensure consistent coating quality and improve profitability.

Today's composite blade products are engineered to offer the same metering performance as steel with up to 4x longer blade life.

Composite blades help sheetfed offset printers:

Increase press uptime due to fewer blade changes
Deliver a steady lay-down of coating consistently
Reduce anilox scoring and prolong anilox life
Minimize handling injuries
Reduce coating consumption

Composite doctor blades wear more slowly and achieve a consistent wipe over a longer period of time. Slow blade wear also helps to preserve anilox integrity which is another critical component in controlling coating film thickness. Composite blades can withstand increasing press speeds and are resistant to the aggressive chemical properties of specialty coatings such as mattes, metallics, pearlescents and UV.

Overall, today's composite doctor blades offer sheetfed offset printers a viable, economical alternative to steel for in-line anilox tower coating applications.
