Rolling Application Stills

Work Room Requirements, in order to insure a clean finished product:

Rollers and Workroom

  • 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

Temp Guage

  • 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

Rolling 1

  • Pour Eco into roller tray

Rolling 2

  • Best results are obtained using a high-density foam roller.

Rolling 3

  • 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)

Rolling 4

  • 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)

Rolling 5

  • 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 Test 1

Fold a dark-ink corner of the canvas, as shown here

Fold Test 2

Fold tight & examine carefully …

Fold Test 3

Cracking indicates the need to apply an additional coat.
