B1 sheetfed offset presses
Printers looking for a new B1 offset press have a choice of four vendors, and multiple machines. Print21 looks at the contenders.
HEIDELBERG SPEEDMASTER SX 102
The world’s biggest press manufacturer has a wide range of B1 presses and has just launched the new-generation Speedmaster
SX 102, which will also be available in 92cm format.
Heidelberg says the press is aimed primarily at commercial print shops that “require a high level of productivity and top-quality perfecting printing”. Typical areas of use range from brochures and commercial print products to inserts for pharmaceutical packaging – and include applications involving very thin materials that need to be produced in a single pass.
The company is promoting
the basic model on its price- performance ratio, with configurations extending all the way through to an autonomous Push-to-Stop perfecting press.
The new 92 format option (650 x 94mm) cuts printing plate costs by up to 20 per cent compared with the conventional 102 sheet format
(720 x 1,020mm), which is also available. Heidelberg says this is a key economic consideration, especially given the sharp rise in raw material prices.
The basic model – already equipped with the tried-and-tested Heidelberg perfecting technology – can be ordered with many other assistance systems transferred from Speedmaster XL technology.
These include Intellistart 3, Intelliline, Intellirun, Wash Assistant and Powder Assistant. If required, the configuration can be extended all the way through to Push-to-Stop for autonomous printing.
With the help of AI, the digital assistance systems also achieve a further significant reduction in the number of manual interventions by operators. Besides saving time, this also means there is less risk of errors.
The Preset Plus feeder and delivery have also been taken over from XL technology, along with further proven solution.
KOMORI LITHRONE G40

The press configuration can be any up to 12 colours.

the carbon footprint of print. With
