“The standard DTG ink curing temperature is 330°F (165°C) for 90 seconds.”

330°F (165°C) for 90 seconds appears verbatim in Source 1, but only as that vendor's own framing, and the same page immediately qualifies it with a 320–340°F range and then contradicts it in its own brand table: Epson OEM and Kodak cure at 320°F/90s, DuPont and Firebird at 330°F for 60–90s, and Image Armor at 350°F for 35s. Source 2 (Firebird) supports 330°F but only for FIREBIRD white ink on dark shirts and gives no 90-second figure. No source establishes 330°F/90s as an industry-wide standard; it is one point inside a documented spread that varies by ink brand, garment, and cure method.
