If you did a search for fabric sublimation printing, you were looking for textile company that does banners, posters, or flags. While this has been around for decades, this particular term has become most closely associated with the large format printing industry, specifically banners and trade show graphics.
I’ve mentioned in other articles on this topic that dye sub printing is a relative newcomer in the sign and banner industry, and that in the past decades, vinyl banners were the main advertising medium for inexpensive temporary advertising. Vinyl items are still a huge industry, and everything from billboards to the sides of buildings and even truck trailers have vinyl displays advertising on them.
