Benefits of a Steel Doctor Blade far outweigh those of a Plastic Doctor Blade.
Plastic Doctor Blades
- Whilst plastic has its place in the print industry, it is limited to non-critical print or coating applications.
- It can offer long life and perform well for industrial applications, but falls short for doctoring a precision film of ink when compared to steel.
- Plastic has a complex recycling process and many products (including doctor blades) end up in landfill.
- The plastic that is disposed of can take many years to break down in the environment or, when incinerated, emits carbon dioxide.
Steel Doctor Blades
- Steel is the first choice Doctor Blade for the majority of printers around the world
- The vast majority of manufactured strip steel is made from 100% recovered steel
- Specially developed steels have been made to meet the challenges of the flexo ink transfer process
- Steel can achieve and maintain a thinner contact area to ensure better print results
- As the material wears the structure of the blade remains the same
- As the blade wears it breaks into tiny particles which migrate easily into the flow of ink
