In commercial printing, the blending of two colors in gradation is usually called a "split" or a "split fountain." In block printing it is generally referred to as a "rainbow roll." For landscapes and such, it helps add depth to the picture. It can also be used to give the illusion of dimension. In "Ohio Street," I used a rainbow roll (RR) for the sky. It really works well for sky, and I'm using it again in the current subtitle piece seen here. I used to use RR a lot more when I worked with smaller sized prints. I've been reluctant to employ RR because I have been so occupied with the other printing issues I've had. Now that those appear to be resolved, I'm looking to perfect RR techniques to bring my prints the vibrancy I want.
This print is a redo of a print I attempted a while back, which fell apart due to ink issues.
