AB Dick Provides Digital Press For Colour Growth
Following its recent exclusive agreement with KBA, AB Dick has installed the first small format 46 Karat digital imaging press at C and H Prototype in Teddington, Middlesex (UK).
Lenze has supplied three drives and a touch screen control system for each of the towers on the press.
One of the many advantages of the innovative re-design is that the press can now incorporate as many print towers as is required and can therefore reproduce as many colours as desired.
This is achievable without adding additional load to the line shaft and having to upgrade the machine's main drive components.
To alleviate the demands placed on the line shaft, a decision was made to incorporate independent Lenze drives for the inker, dampener and wash-up rolls.
This modification led to excellent speed holding and synchronisation of the inking rollers with no detrimental affect on print quality.
The system, known as the Crabtree QPrint, reduces the load on the line shaft as the localised drives assume some of its functionality, resulting in a more efficient printing process.
The concept of independent drives is crucial to retrofitting older machines, where the line shaft speed and direction of rotation is not always consistent.
