The Heidelberg GTO 52-4 Straight 4 Color Press is a four-colour offset printing press — sometimes referred to as a four-colour offset litho press — used for producing full-colour printed materials across commercial, packaging, and general print production applications. Heidelberg is one of the world's most established names in sheet-fed offset printing technology, with a long history of supplying presses and finishing equipment to professional print shops and production facilities worldwide.
This particular machine dates from 1986 and is currently located in Estonia. It is reported to be in top condition and remains in active production use, which speaks to its continued reliability. A test run is available, giving prospective buyers the opportunity to evaluate the press before committing to a purchase.
The press handles a maximum sheet size of 52 × 36 cm (20 × 14 inches) and has accumulated an impression count of 50 million, a figure that is common for a well-maintained press of this age and class. The configuration is straight printing across all four colours in a single pass.
In terms of equipment and features, the press is fitted with an Alcolor dampening system, which provides continuous, alcohol-based dampening for consistent ink-water balance across the run. Sector inking is also specified, referring to a zonal ink control arrangement that allows precise ink distribution across the width of the sheet. A Baldwin refrigeration unit is included, used to cool the dampening solution and help maintain stable printing conditions during production. The machine is noted as a Plus version, indicating an upgraded specification within the GTO series.
