Trading Update

The Board of Scientific Digital Imaging is pleased to provide an update on trading following its financial year-end of 30 April 2010.

The Board is pleased to report that the Group has performed broadly as anticipated and that the results for the year will show trading profits a little ahead of market expectations, in part due to better than expected performance at Atik and from Synoptics in the US.
