60 durometer is one of the softest blades and allows for a thicker ink deposit through lower mesh counts. It's ideal for special effects like puff, high density, glitters, and shimmers.
70 durometer is by most popular and versatile in the garment industry. It's a great general purpose blade for just about everything.
80 durometer provides a stronger force and leaves minimal ink deposit. This durometer is best for designs going through higher mesh counts with lots of fine details and halftones where a think ink deposit is needed for design clarity.
70/90/70 triple durometer gives you the benefits of the 70 durometer blade edge, which creates a good deposit of ink. With 90 durometer as the spine, you'll experience greater pressure applied during printing with minimal squeegee blade deflection. The triple durometer allows more ink to be laid down compared to an 80 durometer blade.
