Confirmed Is Not Checked.
What does "Confirmed" mean on a certificate, and on our own register?
The question: What does "Confirmed" actually mean, on a certificate and on our own register?
Three vendor pages give three DTF powder humidity limits, and none names a test. OEKO-TEX's ECO PASSPORT covers inks, not the printed shirt. The FDA mug rule has no rim band. And a correction of our own: verdict 84 was rated Confirmed on a page whose figures did not add up.
Show notes and sources
DTF powder humidity
Three vendor pages, three limits: 35% or lower, below 50%, and 40 to 60%. The third starts five points above where the first stops (40 − 35, our arithmetic). None names a test.
ECO PASSPORT on inks
Roland DG announced ECO PASSPORT for its DTG inks on 5 November 2020, and Brother on 8 January 2018. Both announcements are old; ask for the certificate number.
STANDARD 100 is a different mark
The textile label "from yarn to finished product" is STANDARD 100. OEKO-TEX certification on DTG kit lands on the inks, not the printer. Confirmed.
The mug rim band
FDA CPG Sec. 545.450 sets a lead limit for cups and mugs and says nothing about a decoration-free band, so "FDA requires a rim band" is False. The 20 mm figure is Canada's: SOR/2016-175 section 3 sets a lead limit on vessels decorated within 20 mm of the rim.
Our correction: verdict 84
The source says curing takes 1.8 to 2.4 kWh per 100 garments and adds 11 to 19 cents a shirt at $0.12 per kWh. Those kilowatt-hours come to about a quarter of a cent a shirt. We had rated it Confirmed; on 7 October 2026 it moved to "figure unverified".
