Rolling Application Stills
Work Room Requirements, in order to insure a clean finished product:
- An enclosed dust free room
- Temperature and humidity control is also desirable for stable drying of the finished prints. Acceptable ranges are:
- Temperature Range 64°F – 80°F (18°C – 26°C)
- Humidity Range 40%RH – 60%RH
Temperature & Humidity Control
- Low humidity will accelerate evaporation, decreasing drying time.
- High humidity slows down evaporation increasing drying time.
- Control can be achieved via some combination of:
• Air Conditioning
• Fans
• Dehumidifiers
• Quartz-halogen lights
• Infrared Heaters
Dilution of Coating
*Tip Since Eco Print Shield is a water based product dilution will be dependent on your relative humidity and room temperature. The lower the humidity the more you will need to dilute it to a maximum of 20%. Most conditions do not require dilution, but if you have any quality control issues, dilution is the solution.
Roller Application
- Pour Eco into roller tray
- Best results are obtained using a high-density foam roller.
- Avoid excess pressure when rolling. Use only the weight of the roller.
- Only roll out about 2 widths of roller to insure a smooth even surface before continuing
- Tip: Have a second roller, dampened with water, to smooth out and remove excess coating as needed.
First Coat (Must be Glossy coating)
- The first 2 coats need to be glossy coating
- Apply a light coat to make sure surface of print is covered thoroughly.
- Using a damp roller, gently roll out bubbles and overlapping ridges, and remove excess coating maintaining an even, slightly translucent appearance and avoiding a solid white opaque.
- Allow to dry completely, when coating becomes clear Note: Higher humidity will take longer.
Second (Must be Glossy coating) &
Third Coat (should be surface of your final coat; Glossy, Matte, Satin)
- Second and third coats can be applied when coating becomes clear, using the same techniques as the first coat.
- Some applications may require a aditional coat, especially if the print will be exposed to a high humidity and/or a high light environment or lots of handling In this case, repeat the first coat steps.
- Use Fold Test to determine if thickness of your coating is acceptable.
The Fold Test:
Confirming Proper Thickness of Coating on Canvas
Fold a dark-ink corner of the canvas, as shown here
Fold tight & examine carefully …
Cracking indicates the need to apply an additional coat.
