🖼️ Book Edge Printing

Technology: Digital inkjet (Ricoh GH2220 print head in the KY-420P)

Process:

1. Clamp the book stack with pages compressed
2. Load design file to the machine software
3. Print head passes over the edge at 900×900 DPI
4. Ink cures; book is complete

Output: Full-color printed design on page edges — photos, illustrations, patterns, text, gradients.

✨ Book Edge Gilding

Technology: Hot stamping foil (heat + pressure)

Process:

1. Trim and compress book block edge
2. Polish edge surface (KY-100: simultaneous)
3. Position foil roll over the edge
4. Heated stamping plate bonds foil at set temperature
5. Carrier film releases — metallic finish complete

Output: Mirror-bright metallic surface — gold, silver, holographic, or colored foil.

📚 Scenario 1: Art book publisher with illustrated fore-edges

Choose: KY-420P Edge Printing. Full-color photographic or illustrated fore-edges require CMYK inkjet — foil gilding cannot reproduce multi-color artwork. The KY-420P handles individual SKUs and short print runs without any setup cost.

☛ Scenario 2: Bible and religious text manufacturer

Choose: KY-530A or KY-100 Gilding. Gold gilt edges are an industry standard in this category — customers expect authentic metallic foil, not simulated printing. High volumes and standardized sizes favor the KY-100 fully automatic gilding machine.

📋 Scenario 3: Stationery brand — custom notebook editions

Choose: KY-420P Edge Printing for seasonal or limited-edition designs with custom artwork on each SKU. Or KY-530A Gilding for a classic gold or silver edge on your core product line. If your range spans both types, consider both machines.

🏠 Scenario 4: Commercial bindery serving multiple publisher clients

Choose both. Publisher A wants gold gilding on their hardcover classics; Publisher B wants a full-color photo fore-edge on their art book. With both the KY-420P and KY-530A, you can serve every client — and market yourself as a full-service book edge finishing house.

🔔 Scenario 5: Print-on-demand and personalized books

Choose: KY-420P Edge Printing. Variable-data printing (each book with a unique name, photo, or design on the edge) is only possible with digital inkjet — the KY-420P changes design between every single book at zero cost.

🏅 Scenario 6: High-volume luxury notebook manufacturer

Choose: KY-100 Fully Automatic Gilding. Unlimited book length/width, auto feeding, simultaneous polishing and gilding — the KY-100 is the only machine that can keep up with industrial-scale notebook and diary production at this level.
