Transfer Dye Sublimation Images supplied by Blueprint Digital I have been asked this question numerous times, and I have seen wonderful results from both ink types. However the results are really dependant on many factors like using the “right” fabric for your ink, using the right ink for purpose, and most importantly, how you profile those inks to achieve vibrant, radiant colours. A backlit fabric needs to have all the concentration of pigment as close to the viewing surface as possible, to ensure a maximum vibrancy.  Ink that penetrates into the fabric too much, either due to fabric construction or print method (direct dye sublimation), may look vibrant in normal light, but will appear bleached and faded when put up into a lightbox.  A UV, Latex or transfer dye sublimation print with all the ink residing on or near the surface will have strong, vibrant colour when lit from the rear. If your method of choice is UV or Latex inks, then a double strike, with your heat lamps at maximum, is important. If focusing on Transfer Dye Sublimation, then it is important to manage the ink profile, dwell time and pressure of your calendar to ensure the sublimation penetrates shallowly but that you transferred enough ink to that surface to ensure vibrancy.  Example of [...]
