One of the many aspects of printing on Streched
Primed Canvas is the short drying time because
the gum is the only matter which actually needs
to dry.
This is good also because 12 to 15 layers of gum
are needed to assure filling in the areas where
the weaving leaves dimples.
I purchas my canvas already primed.
Then brushed on two thin coatings of gelatine
and hardened the gelatine in a formaldehyde
solution. The canvases work best if aged a
couple of months after this treatment.
When developing the print the canvas will float
like a boat.There is an advantage of ease of
handling the canvas and it won't disintegrate
like paper can.
The effect can be painterly. The build up of gum in the
darkest tones creates a slight relief.
Highlights are as much a problem as they can be with
paper however. I suppose the old combination of Platnum
and gum is the best solution but maby someone out there
has another suggestion.
