If you've always been curious on how DTF printers work, this video is for you.
Welcome to a special Deep Dive With Colin! This week Robb from OmniPrint - the product lead for OmniDTF printers - breaks down and demystifies the inner workings of Direct-to-Film (DTF) printing.
Colin & Robb go deep into:
Printer Engineering & Development
How every OmniDTF component is engineered—from precise X & Y motors, gear ratios, and belt tension to rigorous quality control ensuring micron-level accuracy.
Color Profiling & Ink Formulation
The process behind achieving true-to-life colors through proprietary ink development and collaboration with 150+ film vendors.
Film & Powder Selection
The impact of film quality and adhesive powder on color density, wash fastness, and overall print durability, with tips to prevent color shift and adhesion issues.
Calibration & Maintenance Tips
Best practices for print head alignment, proper nozzle registration, and daily ink tank care (especially for white ink), including managing temperature and humidity.
Heat Press Settings & Press Techniques
Optimal heat press operation—ideal temperatures, press times, and pressures needed to bond ink, powder, and substrate for long-lasting prints.
