Carriers have been developed to improve the quality of "burns" on thermal style transfer machines by evenly spreading thermal energy over the entire Spirit® Thermal Transfer Paper. Many old machines- like the 3M Secretary- develop hotspots as they get older; our Carriers have been proven to reduce over- and underexposure on these machines, allowing tattoo artists to get even and clear stencils every time.

Always use a Spirit® Carrier on thermal machines.
