Panstoria uses 25 gauge stainless steel wire stitching for hardcover binding, and PUR adhesive for softcover books. I contacted Werner Rebsamen with the Hardcover Binders International, and he specifically cautioned against the use of stainless steel wire for this purpose, indicating that similar bindings had failed prematurely when tested with the Universal Book Tester. In addition, ISO standards for hardcover books do not recommend metal stitching. Panstoria Photo Book Review, September 24, 2013
Because, I was uncertain about the construction of the Panstoria photo book binding, I sent a sample to a friend in the book binding industry. He used the Universal Book Tester or UBT to examine the strength of the binding. The UBT uses a tumbling motion to test the strength of book bindings.
In this test, Panstoria’s photo book (left) did not perform as well as the Creative Memories photo book (right). It showed greater separation at the spine and some enlargement of the stitching holes that was not apparent with the Creative Memories photo book. Both books, however, performed well, and I can safely say I am comfortable with the process that Panstoria uses to assemble their books. I do not believe that Panstoria’s photo books will fall apart over time.
As I have indicated in the previous parts of this review, overall, I prefer Creative Memories’ photo books to Panstoria’s. In side-by-side comparisons, they are better. However, Creative Memories photo books are no longer available, and I am comfortable with Panstoria’s photo books as a reasonable option at this time. For Part 4 of this review see Panstoria Photo Book Review Part 4.
Note: Only the standard hardcover photo book was tested in the UBT. The test that was completed test does not apply to softcover binding or lay-flat pages.
