I am having extreme problems registering a contour cut on Printable Glitter Heat Transfer Material on out Titan3 ARMS Plotter. It seems that the plotter will not recognize the printed registration marks possibly because of the reflective qualities of the material. It passes the registration marks up and starts looking along the edge of the material or refuses look go find them at all. Has anyone had this problem? I have found a work around but it involves a lengthy process of adhering white calendar vinyl onto the glitter material and then printing, then cutting. Too much time. Can anyone help? Thanks in advance.
