Lenticular art

The most critical factor is the LPI (Lines Per Inch) of the lenticular lens, which typically ranges from 40 to 161 LPI. For large-format posters, a lower LPI (40-62) is preferred for depth, while small handheld items like cards require a higher LPI (75-161) for clarity. Additionally, verify the material type (PET, PP, or PVC); PET is the industry standard for high-end art due to its superior transparency and UV resistance.

Request samples to check for 'ghosting' (image bleeding) and alignment precision. High-quality lenticular art should have a smooth transition between images (for flip effects) or a clear sense of spatial layers (for 3D effects). Ensure the supplier uses UV offset printing or high-resolution inkjet printing directly onto the lens for maximum durability and color vibrancy.

For international markets, products must meet REACH and RoHS standards to ensure they are free from harmful phthalates and heavy metals. If the art is intended for promotional use or children's environments, ensure it passes EN71 (EU) or ASTM F963 (US) safety testing. Always ask for certified lab reports from the manufacturer.

Yes, most professional manufacturers on Made-in-China.com offer OEM/ODM services. You should provide high-resolution source files (PSD or AI) with layered elements to allow the supplier's designers to create the interlaced files necessary for the 3D or flip effect. Confirm if they provide digital 3D proofs before physical sampling.

The primary risk is surface scratching and warping. Lenticular sheets are sensitive to extreme temperature fluctuations and pressure. Ensure the supplier uses protective PE film on each piece and employs reinforced corner protectors and moisture-proof packaging within the shipping cartons.

Lenticular printing involves high setup costs (plate making and calibration). For small batches, expect a higher unit price. To optimize costs, aim for an MOQ of 500-1,000 pieces. Negotiate for a sample fee rebate where the cost of the prototype is deducted from your first bulk order.

Always use Secured Trading Services provided by Made-in-China.com to protect your payment. Do not release the full balance until a third-party pre-shipment inspection confirms the visual effects and quantity match the Proforma Invoice. Use Escrow-based payment terms whenever possible for first-time orders.

Verify the HS Code (typically 3926.90 or 4911.91) with your customs broker to determine applicable import duties and anti-dumping taxes. Ensure the supplier provides a complete Commercial Invoice, Packing List, and Certificate of Origin to facilitate smooth customs clearance and avoid costly port delays.
