Obvious example of improper closure of book cartons. Although the contract
called for cardboard liners,
top and bottom, and full labeling on two contiguous sides, these books were
shipped by the printer with cartons gaping, exposing a thin, soft plastic
sheet of uncertain utility. In some cases the Express shipper may have added
their own brown tape to strengthen the inadequate handling (picture B), but
of course this covers the only label on the
carton.

1. Examples of digitally-printed covers
that warped because of improper lamination or handling of the stock
("cross-grain"). Also the paper text block may be "wavy" when text printing
is done cross-grain of the paper. Posted by

2. Another example of improperly printed covers,
where the printing is not centered on the spine (B-2) and another where there
are folds in the upper spine and back cover (B-1). Pictured are the two
digitally-printed books to compare with one offset-printed book, O-1. Note
also the differences in color. The two digitally-printed books (B-1 and B-2)
colors vary significantly and neither is the same as the offset-printed example,
although this may be partially due to the conversion of the cover file
(originally a 300 dpi TIFF which was probably offset printed at 1200 or higher
dpi) to a PDF which usually prints at 600 dpi. So much difference in color
is unusual.

Another view for comparisons.
O-1 is the original, printed by offset or web..
B-2 has the spine print centering problem.
Notice the fold in the cover at the top of the spine in B-1.
B-1 and B-2 are digitally printed.

3. Examples of poor cartons and poor packaging

The usual standard for cardboard quality is 275 test. Less sturdy material
results in perforation as shown twice here. Use of "peanuts" for filling
space in partially- filled cartons leads frequently to split corners and
rupturing of cartons. Cartons should be tightly packed and full, using cardboard
sheets of full area of the carton as filler if necessary. Shrink wrapping
of the books helps to preserve them, even when all else fails. Note that
these cartons are not even labelled with the title of the books contained.
Wrong.

Below are the same ISBNs printed by offset and digital printing.
While the digitally-printed version works fairly well in most scanners
the differences are obvious and the digitally-printed version may give some
scanners difficulties.
