There are two basic methods of applying motifs ( transfers) when using planar heat-setting devices. The methods differ in the direction of heat that affects the stone. While using the former (1), the transfer motif, pre-arranged on a transfer foil, is temporarily affixed onto the right side of the carrier fabrics. The heat emitted by the devices’s upper heating element penetrates the stone from above, affecting the adhesive layer applied to the bottom of the stone.
While using the latter (2), the fabric with the temporarily affixed transfer motifs is turned over with its reverse side facing up. The heat emitted by the upper heating elements penetrates the carrier fabric, dirrectly affecting the adhesive layer on the bottom of the stone. The advantage of the first method is a lower probability of burning the fabrics, but on the other hand, it requires longer application times.
Compared with the point heat-setting devices, the planar heat-setting devices, generally speaking, require longer times and lower temperatures.

NOTE:
All application values specified in the table are guidelines only. The optimization of these for the particular size of the stone, type of textile material and any setting device requires testing on a sample piece of the carrier material used.
