Selecting the right Mimaki knife blade is critical for achieving precise cuts across different materials, ranging from standard vinyl to thick reflective sheets or heavy cardboard. Most Mimaki blades share a standard 0.3 mm offset, though specialized blades for fine detail or thick materials may vary.

Blade Selection Guide by Application
Selecting a blade depends primarily on material thickness and density:
· Thin Films (1-2 mil): A 30° blade is often used for very thin films like window tint or rice paper to prevent tearing.
· Standard Media (2-6 mil): A 45° blade (such as · SPB-0001· ) is the "all-purpose" choice for cast and calendered vinyl, heat transfer films, and stickers.
· Thick/Dense Media (>6 mil): A 60° blade provides a steeper angle for better penetration into thick materials like magnetic sheets, glitter HTV, or prismatic reflective films.
· Intricate Designs: For very small text or complex logos, use a blade with a lower offset (0.15mm) to ensure the blade can turn more accurately in tight corners.
·
Maintenance and Setup Tips
· Blade Depth Calibration: The blade should only extend about half the thickness of a credit card. A successful test cut should slice the top layer but only leave a light score on the backing sheet.
· Blade Holders: It is common practice to keep multiple blade holders pre-set for different materials (e.g., one for 45° vinyl and one for 60° thick materials) to avoid constant re-adjustment.
· Machine Settings: When switching blade angles, you must update the offset value in your cutter's settings (e.g., from 0.3mm to 0.75mm) to maintain corner accuracy
