I spent all day today printing with DTF inks, film, etc.
I think the biggest advantage is you can slightly modify an Epson desktop printer and run the sheets through so cost to enter will be lower than DTG since you won’t need add on electronics or a platen system.
Per print will be more expensive than DTG because of the film costs especially on white shirts. Also, it feels a bit like a “iron on” transfer.
I don’t think it’s a DTG killer as some are hyping it to be. It has many of the same limitations that other transfer processes have.
