CHROMA is the world’s first full-colour laser engraving technology for polycarbonate identity documents, delivering lifelike portraits with up to 16.7 million colours equivalent to 1200 DPI. Developed by TOPPAN Security, the technology embeds vibrant images beneath the surface for unmatched durability, tamper resistance, and compliance with ICAO standards. Using a single laser source and subtractive colour model, CHROMA achieves the highest definition in the market, photo-realistic portraits with unparalleled vibrance, and maximum security through subsurface engraving. This is a new standard for colour laser portraits.
