I uploaded a small book directly from Lightroom to Blurb and when I received it, the print quality was atrocious.
I've been going back & forth with Blurb support, but they don't seem to be able to answer my question.
I did a bit of troubleshooting on my own by saving the project as .pdf and .jpg rather than exporting it to Blurb. The .pdf and .jpg exports look fine and print fine at home.
As an experiment, I tried reducing the ppi on the .pdf export to 150. This .pdf looks a exactly like the books that came from blurb.
Customer support has offered to re-print the books, but I'm concerned that I will get the same product unless we change something.
Has anyone encountered this problem before?
Does anyone know of settings (print, pdf export, etc) that impact the Blurb upload from Lightroom, or is this entirely on Blurb's side of things?
Should I just punt on the direct Lightroom export and upload the 300 ppi .pdf to Blurb?
I am not sure that that is right as when I have printed books they have been 300ppi, have a look at: Use Blurb and profiles
Thanks for the response. I know the images are supposed to be 300 ppi and that the Lightroom book module will give a warning for anything under 200 ppi. I hadn't seet the Blurb profil information before. The sentence about conversion to CMYK gives me another clue.
The problem I have is that the book that came back APPEARS to have been converted to 150 ppi at some point. Perhaps when they converted to CMYK. I'm trying to identify if there is anything that I did to create the problem (i.e. that I need to correct before a re-print).
