Have you ever stood in front of a DTF printer at a trade show and had a salesperson give you specific performance numbers? I have often been provided inaccurate information, even while standing right in front of a running machine.
I recently had a discussion with a salesperson regarding a printer using 23 5/8" film that he insisted was 24". When I used a tape measure to prove otherwise, his response was simply that it was "close enough." He further claimed this two-head printer could outperform most 4-to-6-head models due to "special" software and waveforms, boasting an output of 180 sq. ft. per hour (approximately 90 linear feet). However, when we timed a test print, the actual output was only 40.91 linear feet per hour.
Furthermore, despite claims of superior color, a test of my standard 324-patch color chart resulted in light, washed-out colors that lacked the density I produce on my current equipment.
When shopping for a DTF system, it is vital to understand your own workflow. The graphics shown at trade shows are often staged, photographic designs with lots of open areas. In contrast, my work requires closely matching screen-printing with 1-5 spot colors that must look consistent on both light and dark garments.
You cannot rely on the "pretty" art shown at trade shows. I recommend doing your homework and requiring salespeople to print your specific artwork. A quality operator will know how to adjust resolution, pass counts, or profiles to ensure the printer meets your actual production needs.
There are many DTF systems available today, but there is also a shortage of educated salespeople and technical support. Ensure you partner with a distributor that provides honest information and has the technical expertise to support your business.
