I've been using Lulu since 2010 and generally have had a very good quality of book printing from the Uk printers Antony Rowe. Recently the UK printers have changed and there has been a noticeable and disappointing loss of quality. Print is no longer centred on both left and right pages (left page margin large, right page margin small), the bleed is much smaller around the edges, the postage packaging less robust, slower delivery times and on several occasions pages have been missing altogether. My books are sheet music A4 size, mostly saddle stitch, sometimes coil bound. There have obviously been reasons for the change of printers but the overall standard has certainly deteriorated. I would urge Lulu to ensure a better standard from the new printers and would be interested to hear of similar problems that others may have encountered.
