Facility: ARTHOME SP. Z O.O. Card Quality Bench, ul. Milczańska 30, 70-107 Szczecin.
Each raw card and graded slab is examined under calibrated 365nm ultraviolet illumination to inspect paper stock fluorescence, surface alterations, inking touch-ups, or counterfeit reprinting.
High-precision stereoscopic microscope inspection verifies offset lithographic rosette ink dot patterns, black ink layer trapping, and cardstock core thickness.
For PSA, BGS, and CGC slabs, ultrasonic welds are probed under polarized light to ensure the casing has never been frosted, opened, or swapped. Anti-counterfeiting holograms are verified against official registries.
Verified slabs are placed in fitted sleeves, double bubble-wrapped, secured between rigid armor boards, and sealed with tamper-evident security tape before DHL Polska dispatch.
