Size, thickness (commonly 5 Mil), roll or sheet formats, specific ink compatibility, anti-curl backing, and branded packaging can usually be tailored. Specify your technical requirements early—such as width for your printers, special coatings for climates with high humidity, or unique branding for retail. Confirm cost implications and minimum order quantities (MOQ) for custom runs. Clear, written agreements reduce the chance of misunderstanding during production.

3. What are typical MOQs, lead times, and accepted payment terms for international orders?
   MOQs often range from 50-500 rolls, depending on customization and supplier scale. Standard lead times are 10-30 days post-payment or deposit, with extra time for large or bespoke orders. Payment terms vary: advance TT, L/C at sight, or, for repeat clients, partial deposit and balance against BL/cargo release. Always clarify payment schedules in the contract. Factor in additional time for export documentation and international logistics, especially for first-time orders or shipments to less-connected trade regions.

4. What quality assurance measures and certifications should I request from suppliers?
   Request evidence of batch quality testing—such as density checks, drying speed analysis, waterproof performance, and compatibility with eco solvent inks. Look for ISO 9001 or similar quality management certificates as benchmarks. Some regions or clients may require REACH or RoHS compliance for environmental safety. Insist on pre-shipment inspection reports and, if possible, third-party lab validation. A strong warranty or satisfaction guarantee—such as a money-back pledge—can indicate supplier confidence in product consistency.

5. How are orders shipped internationally, and what logistic support can suppliers offer?
   Major suppliers typically provide both air and sea freight options and can arrange door-to-door, port-to-port, or EXW/FCA terms. Leading exporters often have partnerships with reliable forwarders and may offer consolidated shipping to reduce landed costs. Confirm if suppliers assist with customs clearance, documents like CE/CO, or certificates of origin, which are particularly important in Africa, the Middle East, or for buyers seeking free trade benefits. Clarify lead times including transit, and ask for tracking and cargo insurance for added security.

6. How should I handle product claims, returns, or disputes if issues arise post-shipment?
   A robust supplier will define a clear claims process—typically requiring notification within a fixed period (e.g., 7-14 days) of delivery. Document product faults with detailed photos and test results. Reliable suppliers may offer replacement shipments, credit notes, or refunds for verified quality issues. For cross-border disputes, align on dispute resolution procedures—such as mediation or arbitration clauses—and clarify which jurisdiction’s law applies. Consider choosing suppliers with proven customer satisfaction guarantees and responsive after-sales teams.

7. Are there specific storage or handling requirements for silk screen positive film, especially in hot or humid environments?
   Proper storage is essential to maintain film performance. Films should be kept flat or upright in cool, dry environments—ideally 15-25°C with less than 60% humidity. Protect film rolls from direct sunlight, excessive heat, or moisture absorption, which could cause curling or ink spreading. Many suppliers recommend acclimatizing the film to your printing environment before use. If shipping to tropical regions in Africa or humid coastal areas in South America, ask for packaging that includes moisture barriers or desiccant packs.

8. What technical support or training do reputable suppliers offer for using silk screen positive film with eco solvent printers?
   Leading suppliers provide comprehensive usage guides, ICC profiles, and troubleshooting documents tailored to popular eco solvent printers. Some offer online training sessions, printable setup parameters, and tips for screen preparation and ink management. For B2B customers, it’s advisable to request dedicated technical contacts or access to a supplier’s support portal. This is especially useful for buyers new to the eco solvent process or needing support in local languages. Prompt access to technical expertise ensures faster onboarding and minimal production downtime.
