◐ Partly true

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

Watch the 1-minute Short

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.

The span it rests on

The standard DTG ink curing temperature is 330°F (165°C) for 90 seconds. While this is the ideal setting for most cotton fabrics, the exact temperature may vary between 320°F and 340°F depending on the ink brand and garment type.

Re-checks

  1. held ◐ Partly true

    The rating stands; one row of our reasoning did not. We gave Image Armor 350°F for 35 seconds, which is Winnerjet's table, not the ink maker. Image Armor's own page gives its E-Series white ink a 35-second cure at 356F with light to medium pressure. The spread we described is wider than we said, not narrower.

    “This is achieved through light to medium pressure on the heat press at 356F.”

  2. held ◐ Partly true

    Our DuPont row was Winnerjet's too, and it does not match DuPont. DuPont's own process guidelines for Artistri Brite P5000 ink cure dark or black cotton on a heat press for 60 to 75 seconds at 356°F (180°C), or 35 seconds at 365°F with a non-stick sheet. The 330 to 345°F range appears only for light shirts with a light white underbase, at 60 to 90 seconds. DuPont's figure for the shirts that carry white ink is 26°F hotter than the "standard" this claim names, which is more evidence for Partly true, not less.

    “60 – 75 seconds at 356°F (180°C)”
