Stencil Systems Comparison:
| Stencil Type |
System features |
Diazo-Photopolymer emulsions
aka: "dual-cure" emulsion |
- Resistant to solvents, water or BOTH
- Highest resolution, mesh bridging and edge definition of direct emulsion systems
- Widest exposure latitude
- Not affected by humidity
- Excellent chemical and mechanical resistance
- Requires sensitizing with Diazo
- Best system for application specific development
|
SBQ-Photopolymer emulsion
aka: "Pure Photopolymer", "One-Pot", "Pre-sensitized" emulsion |
- Resistant to solvents, water or BOTH
- Fastest exposure speed
- Very good resolution, mesh bridging and edge definition
- Narrow exposure latitude
- Not affected by humidity
- Very good chemical and mechanical resistance
- Pre-sensitized - ready to use
- Best system for digital direct exposure and direct projection systems
|
| Diazo emulsion |
- Resistant to EITHER solvents or water
- Good resolution, mesh bridging and edge definition
- Good exposure latitude
- Affected by humidity
- Very good chemical and mechanical resistance
- Very easy to reclaim (solvent resistant types)
- Requires sensitizing with Diazo
|
| Capillary films |
- Resistant to solvents, water or BOTH
- Fastest application speed
- Very good resolution
- Exellent mesh bridging and edge definition
- Excellent Rz-values at low emulsion over mesh thickness
- Very good exposure latitude
- Very good chemical and mechanical resistance
- Pre-sensitized - ready to use
