Testing a new doctor blade in your printing operation should be a collaboration with your suppler that boosts performance while avoiding costly guesswork. Instead of randomly ordering samples, follow a systematic, data-driven approach.
Collaborative Setup
Start by sharing key details about your press—dimensions, machine model, blade holder type, ink specifics, and any pain points you are experiencing. This information lets your supplier recommend tailored doctor blades rather than generic samples. There are a lot of options in terms of material type, thickness, and edge configuration.
Initiate the Trial
Your supplier will likely send you one or more blades based on your provided data. Appreciate what these are and take care when testing them. They’re designed for your specific needs and should be used in a controlled production run.
Conduct the Production Run
Install and test the blades under normal operating conditions. Consider starting on a single print/coating station if the blade is new to you. Contact your supplier with any questions related to setup or installation and alignment. Clean the blade holder or chamber, using minimal blade pressure.
Feedback
Complete any surveys your supplier has seeking feedback on the sample performance. Record important details and observations made during the testing related to blade longevity, metering quality, and any anomalies. Feedback is especially important if the blade fails as this can help your supplier make alternative recommendations by changing blade material, thickness, or edge configuration.
The Takeaway
An iterative, collaborative testing process is more efficient than random sampling. By working closely with your supplier—starting with detailed information, running controlled trials, carefully documenting results, and refining based on feedback—you achieve optimal performance and a long-term printing solution. Embrace this method to streamline your doctor blade selection and keep your press running at peak efficiency.
