Description
Saati Duralife 70/90/70 Triple Durometer — Anti-Bow Urethane Squeegee Blade
A triple durometer blade solves a real problem in screen printing: you want blade flexibility at the contact edge for fabric conformance and ink transfer, but you also want blade rigidity throughout the stroke so the blade doesn’t bow and create uneven pressure. A single-durometer blade forces you to choose one or the other. The 70/90/70 triple has soft outer layers (70) that contact the mesh and fabric naturally, bonded to a harder center core (90) that resists bowing and maintains consistent printing pressure across the full stroke. Most popular triple for general garment printing.
How Triple Durometer Works
Outer Layers: 70 Duro
70 duro outer layers contact the mesh and fabric — flexible enough for good ink transfer and fabric conformance, providing the feel of a standard 70 duro at the print edge.
Center Core: 90 Duro
90 duro core provides structural rigidity — resists blade bowing across the squeegee length during the print stroke, maintaining consistent pressure from end to end.
Key Features
🔬
Saati Duralife Urethane
All three layers are urethane — chemical resistant, longer-lasting, consistently hardened, and sharpenable. Not rubber.
📐
Anti-Bow Rigidity
The 90 duro core resists the bowing that single-durometer soft blades exhibit across wide screens — delivering consistent ink deposit from edge to edge on large format prints.
🤲
Flexible Print Edge
The 70 duro outer layer contacts the mesh and fabric — providing good ink transfer and fabric conformance without requiring a heavy-handed stroke.
🧪
Chemical Resistant
Resists plastisol solvents, water-based chemistry, discharge activators, and screen cleaning chemicals across all three layers.
🔪
Sharpenable
Sharpen the outer urethane edge with any standard squeegee sharpener to maintain a clean print edge across the blade’s service life.

See It in Action: Understanding Squeegee Durometer
📐 Understanding Squeegee Durometer
Durometer is the Shore A hardness rating of the squeegee blade — a standardized measurement of how stiff or flexible the blade material is. It directly determines how much ink passes through the mesh and the sharpness of the printed edge.
↑ Softer (60)
More flexible → more pressure on mesh → more ink deposit → heavier prints
⚖️ Medium (70)
Balanced → versatile across inks, mesh counts, and substrates → the shop standard
↓ Harder (80)
More rigid → less flex → less ink deposit → sharper edges → fine detail
Full Durometer Selection Guide
| Durometer | Feel | Best For | Product |
|---|---|---|---|
| 60 | Soft | Textile printing: thick inks, heavy garment textures, low mesh counts (60–110). Simulated process printing on textured surfaces. Maximum ink deposit. | 60 Duro Blade |
| 70 | Medium | General garment printing: plastisol and water-based on flat textiles, standard mesh (110–200). The most versatile durometer — the starting point for most shops. | 70 Duro Blade |
| 80 | Hard | High mesh / fine detail: halftones, process printing, 4-color process, fine line work, high mesh counts (200–305+). Less ink deposit, sharper edge definition. | 80 Duro Blade |
| 70/90/70 ← This Product | Triple | Best of both worlds: soft outer layers (70) grip the fabric and conform to the mesh — hard center core (90) provides rigidity without fatigue. Most popular triple for general garment printing. | This product |
| 60/90/60 | Triple | Maximum ink deposit with rigidity: softest outer layers (60) for maximum conformance and ink transfer — hard center (90) for blade stability. Heavy ink deposit jobs, thick plastisol, specialty inks. | 60/90/60 Triple |
🔬 Why Urethane? Saati Duralife vs. Standard Rubber
Saati Duralife Urethane
- Resistant to plastisol, water-based, and discharge inks
- Resistant to solvents and screen cleaning chemicals
- Maintains consistent durometer across the blade lifespan
- Holds a sharper edge longer between sharpenings
- Lower abrasion wear on emulsion stencils
Standard Rubber Blades
- Can swell or soften when exposed to solvents
- Durometer drifts over time as rubber degrades
- Loses edge sharpness faster
- Lower cost upfront, but higher replacement frequency
🔧 Squeegee Blade Care & Sharpening
- Clean blades immediately after printing — dried ink hardens on urethane and requires more aggressive cleaning, which accelerates edge wear.
- Store blades edge-up or hanging — never lay a squeegee flat with blade down. The edge deforms under the handle weight over time.
- Sharpen regularly — a dull blade requires more pressure to shear ink through the mesh, which increases mesh wear, stencil wear, and wrist fatigue. Sharpen when you notice ink deposit becoming uneven or edges ragged.
- Inspect for nicks and flat spots — a nicked blade leaves streaks and uneven ink deposit. Sharpen past the nick or replace the blade section.
- Use a squeegee sharpener or lap grinder — hand sharpening on sandpaper creates uneven bevels. A dedicated sharpener produces a consistent edge across the full blade length.

FREQUENTLY ASKED QUESTIONS
What is the practical benefit of a triple durometer blade?
The main benefit is consistent pressure across the full blade width during the print stroke. Single durometer blades can bow (flex inward) in the center on wide prints, creating a lighter ink deposit in the middle. The hard center core of a triple durometer blade resists this bowing, delivering more even ink deposit from edge to edge — especially on wider screens.
Is 70/90/70 or 60/90/60 better for general printing?
70/90/70 is the more versatile choice for general garment printing — the 70 outer layers work across a wide range of inks and mesh counts. 60/90/60 is for maximum ink deposit — the softer 60 outer layers push more ink through, making it better for thick inks, heavy deposit jobs, and low mesh printing. If you’re unsure, start with 70/90/70.
Can triple durometer blades be sharpened like single durometer?
Yes — sharpen the triple durometer blade the same way as a single durometer blade. The edge you sharpen is the outer urethane layer (70 duro), which sharpens like any urethane blade. The core does not need to be exposed at the printing edge.
How is triple durometer constructed?
Triple durometer blades are co-extruded — all three layers are produced simultaneously as a single bonded urethane unit, not glued or laminated layers. The 70/90/70 construction results in a blade where the outer layers and core behave as one continuous material, maintaining consistent hardness transitions across the full blade profile.
