c) the resultant pattern is clear with soft edges where the dye has lightly penetrated.
d) the wax is then removed by boiling or least washing at a high temperature
Another form of wax resist is to partially break or crack the wax before the printing, so that as the dye penetrates it creates a much more random design or striata or rippled effect.
In silk printing, the dye is applied to the flat surface of the length of fabric which is fixed to a frame or table. Hot wax pen is used to outline pattern or space, so preventing any dye seeping into the next space.
