PRODUCTION NOTES
The Challenge
his order includes three distinct editions: Standard, Signed, and Limited.
The production logic is complex: all three versions share the front endpapers, but the back endpapers are unique (containing different ISBNs). Furthermore, only the "Signed" and "Limited" editions require a tipped-in signature page manually glued between pages 2 and 3, with a strict 3mm glue strip requirement.
Mixing these components or misplacing the signature page would result in delivery failure.
Our Solution
Logical Segregation: We established a strict collation protocol. On the production line, the three different back endpapers were marked with color-coded visual indicators to prevent mixing.
Dedicated Station: We set up a specific manual workstation solely for the "Signed" and "Limited" editions to handle the tipped-in pages.
Controlled Gluing: A custom 3mm template was used to ensure the glue strip was consistent and clean, preventing overflow and maintaining page flatness.
The Challenge
The book features a 0.5mm double-sided matte soft PVC jacket. The design specification requires the jacket to fit the cover tightly.
Assembling a thick, semi-rigid PVC jacket over a paper cover presents a risk of scratching the printed surface or damaging the book corners during insertion due to friction.
Our Solution
Friction Reduction Method: We implemented a slip-sheet assembly technique. A thin protective film is placed between the cover and the PVC during insertion to eliminate friction. Once the jacket is positioned, the film is removed.
Skill Verification: Operators underwent specific training for this material. Only those who passed a practical assessment were assigned to this station, ensuring consistent handling and damage-free assembly.
The Challenge
The client provided original hand-signed pages for the special editions.
The instruction mandated strict control: "Extra signature pages must be destroyed." Any leakage of these signed pages would affect the market integrity of the limited edition.
