ABSTRACT
In monochromatic printing, it is best to use strong, dark pigments, such as lampblack or the other blacks, Prussian blue, burnt umber, and Vandyke. Colors may be mixed to achieve a hue that most enhances the image. Lighter colors may be used if the users expect the print to remain a monochrome. The actual prints are not monochromatic in the strictest sense because in each case, the residue of incompletely removed gum gives the print a touch of color. Oil paint is rather expensive. A common, heavy stencil brush works best, although oil paint can be worked into the paper with almost any object, including bits of rag, paper toweling, or even fingers. A conventional paintbrush, large or small, would be completely ineffective for working in the oil paint. Amorig oil paints, there is a virtually infinite selection of brands and colors. This can be appreciated by visiting a first-rate art supply store or reading through a comprehensive catalog.
