Practical Considerations for Choosing the Right Knife

• Flexibility versus Rigidity – A blade may be slightly flexible for mixing or should be rigid for scooping—it depends on your workflow. Opt for a blade that’s taper-shaped: thicker near the handle and thinner at the tip for better control and durability Impressions.

• Handle and Grip Design – Some knives include a lip to hook over ink buckets, keeping the tool handy without contaminating your workspace Impressions.

• Time Saved — Easy to clean and deploy, they reduce setup and teardown — more uptime for printing.

• Ink Conservation — Their precise edge helps scrape out nearly every bit of ink from fountains or buckets, reducing waste formtechservices.com.
