We used output created on six DTF devices spanning multiple vendors ranging from desktop ‘Etsy’ devices to production print shop commercial operations. Before you ask, we are not identifying the vendors or models; this is an educational piece to bring awareness around the importance of washing conditions, not a name and shame exposé. The results The findings were telling. Initial cycles did not yield a definitive outcome, with evidence suggesting that both conditions could potentially harm the prints. However, as the number of cycles increased, a clear pattern emerged with ‘high temp’ washing proving to be the greater adversary, with over 50% of the garments reaching the point where they became unsuitable for public wear within 20 washes. Conversely, garments subjected to high-spin conditions maintained a level of integrity that, while not pristine, was deemed acceptable for everyday use. This investigation underscores the necessity for both consumers and suppliers to understand the importance of optimal washing conditions for DTF-decorated garments. Adhering to recommended laundering practices can greatly extend the life of these prints, ensuring customer satisfaction and fostering brand loyalty. Foiled again Our next educational group test will be taking a look at the performance of foil-based DTF films, which are starting to become more popular on stands at trade shows. This decorative blingeffect has been a stalwart of heat transfer vinyl (HTV) technology for many years. DTF is looking to take some of the lucrative revenue stream away using white ink printing to transfer the foil straight onto the garment without the need for any weeding. Check in withImages magazine where we will be sharing the results of this fascinating group test.
