Hello and thanks for the great book. Just sharing some printer feedback - my hardback cover had a line going down the side that looked like a color problem or ran out of ink. There was another issue that lulu had to address with the cover anyways, but for this they said 'I am able to see that the line on the front cover is not present on the source file, but does appear on the print-ready file. This appears to be the result of unflattened transparencies within the file that become visible as part of our normalization process. ' They then sent me a link to a flattened hardcover file and had me revise the upload for them to reprint it. I used the files provided here for lulu but if no one else was having any issues maybe it's nothing on this end after all; I just wanted to share in case this means anything to anyone else out there :)
