Once you’ve printed your design onto a piece or roll of transfer paper, you need to transfer that design to your substrate. This requires a combination of heat and pressure to cause the solid dye particles on the transfer paper to change into a sublimates, so that it separates from the paper and is permanently bonded to the polyester threads or coating.

So what should you be looking for when purchasing a rotary heat press for wide format sublimation printing? What are the options
If you’re mainly printing onto made-up apparel, small areas of substrate, or you are likely to also want to print onto hard substrates, then a flatbed is the way to go. However, if your sublimation printing operation is geared more towards high volume printing of textiles, sports and fashion wear, or you wish to print long lengths of substrate then you’ll want to consider a rotary press. These ‘tend’ to be more expensive than flatbeds, depending on the individual press’s size and spec, but they also offer much faster production speeds.

Rotary heat press machine have a cylindrical felt covered drum, which is filled with oil. The oil is heated to the required temperature (200°C) creating an even and stable heat across the entire width of the drum. For roll-to-roll printing, rolls of the substrate and printed transfer paper are transported together around the heated drum, remaining in contact with the drum for a given length of time.

A roller heat press machine is used to apply tension to the tubular felt, which in turn applies pressure to the substrate and paper, holding it against the heated drum to facilitate the sublimation process. Separate rollers may also transport ‘protection paper’, which is used to prevent any excess gas that doesn’t sublimate into the substrate from transferring to the felt on the drum, which could lead to unwanted transfer of the dye back onto the roll of substrate.
