Rollback technology allows a Dye Sub Printer to print smaller images on larger media without wasting unused media. This is usually a benefit when printing 6×4 images on 6×8 media.
The Rollback (or rewind) feature works by remembering which parts of the ribbon were only partly used when you print different image sizes (using 6×4 photos on a 6×8 ribbon.)
When you then print another 6×4 print, the printer will rewind the ribbon until the unused part is located and use that part of the ribbon, so avoiding wastage.
Rollback Technology uses the same Dye Sublimation Media as the rollback functionality is built into the printer and not the media.
Note: Some Print Modes may disable the Rollback feature and Rollback does not work if the media is changed. Rollback will typically rollback one 6×8 print to use an existing unused 6×4 print.
Mitsubishi was the first company to use this technology in a compact Dye Sublimation Photo Printer.
