Many thanks to both of you for your replies.  I guess you've both convinced me to get QU to try out on some lenticular sheets.  Regards, Geoff.

Under 2012.100 update posted 8/15/2011 it was said that there would be a capability released later that year.  On going through the list of updates I did not see any related update release.  Getting a 3D lenticular image resized so that it would precisely align to the lenticular pitch test result is crucial to get a quality 3D image.  Does your latest release accommodate this precision?

Finally I have an HP Officejet Pro 8600 and notice in the technical detail that when in colour mode and using high quality photographic 5* Professional media it has the capability to print at 4800x1200 DPI.  Is this a capability that Qimage can take advantage of?
