KBA and other press manufacturers have teamed up with the VDMA (German Machinery and Plant Manufacturers’ Association) to introduce an energy consumption value for printing presses.
Where printing presses are concerned, comparisons of energy consumption are only meaningful if the same criteria are applied - if standardised testing procedures are used, says KBA. If the values measured are to be both reliable and valid, test conditions and results must be standardised and documented in full. Since each and every measurement is prone to error, multiple measurements must be taken to allow the average to be calculated and the divergence noted.
The question is: how realistic are standardised consumption figures?
The fuel consumption data published in promotional literature and catalogues may comply with legal regulations, but have very little to do with actual practice. They are purely theoretical figures based on a uniform measuring system that allows emissions from different types of vehicle to be compared. The same would apply to energy consumption figures for presses: they would furnish prospective buyers with a basis for comparison.
For all issues relating to energy savings, companies are invited to contact KBA, whose experts will use consumption measurements ‘to track down hidden energy guzzlers’, offer advice on reducing total energy consumption and provide on-the-spot proposals for enhancing energy efficiency and cutting costs.
The company will also also offer ‘live’ demonstrations to calculate order-specific energy consumption in shopfloor conditions.
