Photo Maskoid

It is possible to selectively tone areas of a print with different toners. The trick is to cover areas not to be toned with either rubber cement or a frisket material, such as Photo Maskoid or Grumbacher Miskit Frisket, both available from art supply stores. If you use rubber cement, dilute it 1 1 with rubber cement thinner. If you use Photo Maskoid, use the red variety as it is easier to see the areas you have covered. 

After the print has been washed according to the toner s instructions, you can remove the mask. Remove Photo Maskoid by touching tape to one edge and pulling it off. Remove rubber cement by carefully rubbing your fingers across the print surface while it is in the final stages of the wash. After the print is dry any previously toned area may be masked and an entirely different area toned with a different color toner. There is no limit to the number of colors that can be applied, or the areas that can be toned.
