While smaller, it can be a practical addition for artists who need a portable, lightweight exposure option.
Key points:
– 25W UV exposure at 395 nm
– Compact and portable design
– Efficient curing suitable for cyanotypes and emulsions
– Durable LED construction for long service life
Buying Guide: Light Tables For Screen Printing And Cyanotypes
- Wavelength and intensity: Most screen printing setups prefer UV exposure around 395 nm. Higher wattage units cure emulsions faster but may require careful distance control to avoid overexposure.
- Exposure area compatibility: Consider frame sizes you commonly use. Look for units that cover your largest screen (10 x 14 inches up to 20 x 24 inches) or offer multiple lamps for larger formats.
- Adjustability: A flexible stand, adjustable height and angle, and even rotation help ensure uniform exposure across different emulsions and stencil designs.
- Timer features: A built-in timing device helps prevent over-exposure. 0.5-minute increments are common and beneficial for precise control.
- Ease of setup: Included manuals, simple mounting hardware, and a minimal number of steps to install contribute to faster workflow integration.
- Durability and maintenance: LED-based UV lamps typically offer long lifespans. Check for robust housing, glass covers for protection, and availability of replacement parts.
- Multi-lamp configurations: For larger runs or greater flexibility, consider sets that include two lamps or full kits with stands and accessories.
- Use cases: If you primarily work with cyanotypes, ensure the unit delivers consistent exposure at the required wavelength and intensity for your chemistry.
- Safety considerations: Use appropriate eye protection and enclosures for the UV exposure area, and follow manufacturer guidelines for installation and operation.
- Budget and space: Higher-wattage, larger exposure units tend to cost more and require more bench space. Balance your needs against available workspace.
