Pick by step
Use offset for collage and base drawing — natural color, smooth printing; 200g-230g cardstock for 3D models, cards and covers — stiff, easy fold/cut; fluorescent for signs and decor — visible from afar.
Safety and eco
Materials for young children should be non-toxic, eco and compliant, with batch QC and eco docs kept for verification.
Procurement
Keep common colors in stock, combine carton and mixed batch to avoid stock-outs, and sample custom styles early for on-time back-to-school delivery.
