Custom Rubber Roller for GTO 46 Printing Press Details
AstraRoll's Custom Rubber Rollers are engineered as direct-fit replacements for the inking and dampening units of the Heidelberg GTO 46 offset press. The GTO 46 is a compact A3-format sheetfed press widely used for short to medium commercial runs. Maintaining correct roller dimensions, hardness, and surface condition is essential for consistent ink transfer and print quality.
Our range covers the full set of positions, with each roller identified by the OEM color-coded end-cap system for error-free installation.
