What's Sublimation Calender Heat Press and What's The Types?

Unlike the other heat presses illustrated in this post, sublimation calender presses don’t have heat blocks. Instead, they use oil or electrically heated drums to heat transfer from a printed roll of paper onto polyester fabric – the roll of paper is attached calendar pressto the press and fed through with the fabric.
Calendar press Average-sized calender presses are available in working widths of around 65″ to 70.9″. Some are simple roll-fed designs and others are designed to enable pre-cut fabric pieces to be fed through individually.
Calender heat presses are ideal for users who want to specialize in cut/sew apparel, décor, and soft-signage. They cannot be used, however, to press rigid substrates. Prices vary a great deal and much of the cost is based on whether it’s electric or oil based and on the size of the drum – a bigger drum means a higher cost. However, a bigger drum also means greater production and faster output. Unlike smaller heat presses, calender presses require a 240V electrical outlet with a double throw (2 pole) set-up.
Calender heat presses are available in the following types:
This is considered to be more of an entry-level calender press that’s lower in cost but can still achieve professional results. Unlike the oil drum version, it’s the air in the electrical drum that’s heated, which enables it to heat up quicker and cool down faster. Something that can be an advantage if you’re running a small but efficient dye-sublimation business.
Oil Drum
Associated with professional dye-sublimation production, the oil drum version is a more expensive calendar press that needs an air compressor to run it. Available in mid-to-high volume production models, they range from shop-sized to industrial-sized presses. The oil in their drums takes longer to heat up than the air in their electrical counterparts, but they maintain heat far better over long periods of time and ensure much better heat-pressing consistency.
