The Paterson Auto Print Washer Standard holds 12 prints 10x12" (25.4x30.5cm) or 24 prints 5x7" (13x18cm) or smaller and greatly reduces the time required to wash fibre-based photo papers. Efficient washing is essential to avoid stains appearing on these prints. The Paterson washer holds each print in a cradle which allows the flow of water to wash each side of the print simultaneously, and eliminates the risk of prints sticking together. Typically, the washer will stand on a sink draining board and is fitted with an inlet hose with tap adaptor and an outlet hose.
