In relief etching, color prints are achieved by utilizing the different levels of the etched metal plate. Because the plate is etched to varying depths, artists can apply different colors to specific levels of the surface.12

The process typically involves the following techniques:

  • Selective Inking: Different rollers are used to apply ink to specific areas. A soft gelatin roller is often used to deposit color into the lower, recessed levels of the plate, while a hard rubber or composition roller is used to ink the high, raised areas.1
  • Viscosity Control: Artists carefully manage the viscosity of the inks to control how they interact when applied to different levels of the plate, which is a critical factor in achieving the desired color results.1
  • Staged Etching: To create these distinct levels, the plate is etched in stages, similar to traditional etching, by protecting areas with a resistant varnish or ground before exposing them to acid.23

This method allows for complex color layering and is a widely used technique in contemporary printmaking.2
