Fast acting negative plate developer, leaves a clean background and preserves image contrast. Use with both grained and smooth plates. Go from development to press in as short a time as possible, added gum content eliminates the need to rinse and gum the plate post development. The plate can be safely kept overnight before running. For longer storage before use we would recommend the more traditional rinsing off with water, followed by an application of Allied Negative Finishing Gum.
