Common Mistakes to Avoid

Wrong Size Selection

Key Consideration: Ordering boxes that are too tight for books with protective sleeves.
Tip: Add 5-10mm to each dimension for easy insertion and protection.

Ignoring Weight Capacity

Key Consideration: Using E-flute for heavy textbooks causes box deformation.
Tip: Use B-flute or BE-flute for items over 5kg.

Poor File Quality

Key Consideration: Low-resolution artwork results in blurry printing.
Tip: Provide 300dpi minimum, convert text to outlines, use CMYK color mode.

No Protective Inserts

Key Consideration: Multiple books slide and damage corners during transit.
Tip: Add custom inserts or dividers for multi-item shipments.
