Photo books are a different design problem
Most personalization tools optimize for one-page products — business cards, flyers, t-shirts. Photo books are 20 to 200 pages with thousands of photos. The UX problems compound: photo organization, intelligent auto-layout, spread editing, page reordering, batch import.
PrintIntegrator's photo book mode handles these as first-class concerns. The customer imports a folder of photos; the engine proposes a layout per spread; the customer edits and reorders without breaking the layout.
Lay-flat vs perfect binding
Binding choice changes what you can do at the spread. Lay-flat photo books support photos that cross the spine because the spread opens completely flat. Perfect-bound and saddle-stitched books need photos clear of the gutter. The layout engine respects the chosen binding and warns the customer when they violate it.
Calendar configurator
Calendars are deceptively complex: regional holidays, week-start conventions, week numbering, fiscal vs calendar year, multi-language month names, custom date highlights for the customer's anniversary or birthday.
PrintIntegrator ships configurations for 30+ countries. Customers pick country, customize one photo per month, add private dates if they want, and check out.
Production output
Output is per-page PDF/X-4 for digital presses or imposed PDF for offset. Spine width is calculated automatically from page count and stock. Cover and interior pages are separate PDFs as your finisher expects.
