DTF ink usually fails to stick to PET film for one of six reasons: printing on the wrong side, low-quality film coating, humidity exposure, static electricity, underfed RIP settings, or old ink. This guide breaks down how to test for each cause and fix it, plus how to choose matched film, ink, and powder that work together as one reliable system.

DTF film, ink, and powder each need specific storage conditions to avoid print failures. Film needs 15-27°C and under 60% humidity; ink needs stable temperatures with regular shaking for white ink; hot melt powder needs airtight, low-humidity storage. Following these guidelines extends shelf life and prevents wasted materials and failed transfers.

This beginner's guide breaks down every essential DTF supply, including printers, PET film, pigment-based inks, adhesive powder, and heat presses. It covers practical buying criteria, curing temperatures, pressing settings, and real startup cost ranges from hobbyist to production scale, helping new DTF printers build a reliable, compatible supply kit from day one.
