If you are constantly waiting for your sublimated products to cool, then consider getting a cooling plate, such as the Kool Plate. This post-press accessory helps increase your productivity by cooling 400 F products in just a few seconds.
It works by sucking heat out of the product you place on it and expediting your cooling time. This helps a lot for flat products. Particularly, I think cooling plates are a must for double-sided products like FRP bag tags as you can press one side and quickly cool to allow you to press the second side.
