6900-4 DTF Printing Machine with Fluorescent Capability

The 6900-4 is a specialized DTF printing machine designed for industrial operations requiring fluorescent output. Operators utilize four Epson I3200 printheads for simultaneous CMYK, fluorescent, and white ink printing. The fluorescent system produces vibrant designs visible under both normal and UV lighting. This makes the unit suitable for sportswear and promotional items requiring high visual impact. Note: Operating environment should maintain 15-25°C and 30-65% humidity. The three-section heating system requires approximately 10-15 minutes warm-up before production.

DTF Heat Transfer Process: Step-by-Step Guide

The DTF heat transfer process using this system typically takes 15-25 minutes per batch. The fluorescent ink capability adds visual impact without changing the basic workflow.

DTF heat transfer artwork design process for fluorescent printing

1. Artwork Design

Prepare artwork in Illustrator or CorelDRAW at 300 DPI minimum. Mirror the design before printing. Fluorescent channels require separate layer setup in the RIP software.

DTF powder application and curing process for heat transfer preparation

3. DTF Powder Application & Curing

TPU powder is applied to tacky ink. The film cures at 100-120°C for 2-3 minutes. The three-section heating system maintains consistent temperature across the curing zone.
