Children’s Book Printing: Safety Standards, Paper Types & Design Tips

Printing children’s books comes with unique responsibilities. Beyond beautiful illustrations and engaging stories, every children’s book must meet strict safety standards — especially for the youngest readers who explore books with their mouths as much as their hands.

Safety Standards: Non-Negotiable

Key Certifications

Standard	Region	Requirements
EN71-3	Europe	Migration of heavy metals from inks/coatings
ASTM F963	USA	Mechanical and chemical safety
CPSIA	USA	Lead content < 90ppm in accessible parts
ISO 8124	International	Generic toy/book safety standard

At QiPrinting, all our children’s book inks are certified non-toxic and compliant with EN71 and ASTM F963. We provide compliance documentation with every order.

What Makes a Book “Child-Safe”?

Non-toxic inks (soy-based, heavy-metal-free)
Rounded corners (no sharp edges for toddlers)
Water-based lamination (no solvent residue)
Sturdy binding (pages can’t be torn out and swallowed)

Design Tips for Children’s Books

Bleed is crucial: Full-bleed illustrations are the norm — provide 5mm bleed on all sides
CMYK, not RGB: Your screen uses RGB; your printer uses CMYK. Convert before exporting.
Safe zone: Keep text and important elements at least 5mm from the trim edge
Gatefold & die-cut: Special effects are possible! Just discuss with your printer early
No tiny text: Children’s books need larger fonts — 14pt minimum for early readers

Special Finishes for Children’s Books

Spot UV: Glossy highlights on specific illustration elements
Foil stamping: Metallic accents on cover artwork
Die-cutting: Custom-shaped pages (windows, peek-a-boos)
Touch-and-feel: Embedded textures (fuzzy patches, rough surfaces)
