The application of designs to fabric, using a machine containing a series of engraved metal rollers positioned around a large padded cylinder. Print paste is fed to the rollers and a doctor blade scrapes the paste from the unengraved portion of the roller. Each roller supplies one colour to the finished design, and as the fabric passes between the roller and the padded cylinder, each colour in the design is applied. Most machines are equipped with eight rollers, although some have sixteen rollers.
