It's called "Colourfix" for the obvious reason. This very permanent, lightfast coated paper withstands all manner of artistic experimentation (and even punishment).
These papers are used successfully in practically all media — pastels, charcoal, pencil, oils, acrylic, gouache, inks, silverpoint, and even watercolor. The natural toothy surface is ideal for pastels, pencil, or charcoal, as it will hold multiple overlays of color without the need to fix between layers.
The absence of fixative allows the velvet bloom and vibrant color of pastel to be preserved. (Apply a final light spray of fixative if desired.)
The unique, fine tooth surface is produced by screen printing Art Spectrum Colourfix Primer onto a heavy weight Hot Press watercolor paper. Available in packs of 10 and 20, 9" × 12" (229 mm × 305 mm) sheets. 140 lb (300 gsm).
Handling Charge - When ordering sheets of paper or board larger than 18” x 24” in quantities of less than 10, a $3.00 per order handling fee applies. Paper or boards may be assorted to reach the quantity of 10.
