I used DPI for what should have been a fairly straightforward job - printing a small “art book”. Multiple (preventable) errors/damages were found on nearly every copy of the perfect-bound books that I ordered. Significant scratches, ink marks/registration lines, poor cropping lines, borders appearing on black pages, glue breaking off from the spine, etc. DPI’s customer service was excellent (and accommodating), as I spoke with several people who offered to reprint my order to ensure that these errors were corrected. The original order was reprinted, and despite added “quality control” - this batch was returned with similar issues. After 4 reprints, (the first two being small test batches), I was left with a pile of books that are completely unusable. When I saw that approximately 75% of the final lot exhibited the same damages, I gave up trying to contact customer service about the issue, as it was clear that this was going to keep happening. I am aware that there is only so much quality control that can be carried out in print houses, but it seems like there was absolutely no communication between the customer service reps that I spoke with and the printers. A more thorough check would have prevented an unnecessary number of reprints and wasted time on both ends.
