A code can look perfect when it leaves the printer and still fail before the product reaches the customer.
This often happens on smooth plastic, aluminum foil, coated cartons and metal parts. The ink appears dry, but rubbing during stacking removes part of the text. Alcohol cleaning causes the batch number to fade. A QR code printed on a glossy pouch reaches the warehouse with several damaged cells and no longer scans reliably.
The printer may not be faulty. The surface and ink were simply not well matched.
PIJ UV printing is useful on materials that do not absorb ordinary ink easily. UV energy cures the printed layer on the surface, making the process suitable for many plastic, metal, foil, pipe and coated-packaging applications where stronger adhesion is required.
Faith’s PIJ system can print text, logos, barcodes and variable QR codes directly on these products without applying a separate label.
Consider a plastic pipe measuring 110 mm in diameter. The factory needs to print a logo, size, production standard, meter count and batch code immediately after extrusion. A weak mark may rub off while the pipes are bundled, dragged across rollers or loaded for transport.
A suitable UV ink and curing arrangement gives the printed information a better chance of surviving normal handling.
Material testing cannot be skipped. “Plastic” may mean PE, PP, PET, PVC or a coated film, and each surface behaves differently. Oil, dust, release agents and low surface energy can reduce adhesion. Conveyor speed and UV power also affect curing.
Approval testing should use the actual product rather than a clean sample plate. Check the result after rubbing, tape pulling and alcohol wiping when those tests match the customer’s process.
UV ink increases the range of materials that can be printed directly. A reliable result still depends on matching the ink, surface, curing energy and production speed.
