Claims11
A method comprising:
- printing an image to a target;
- printing an image-wise security feature to the target with a clear material transferred from an image-wise mass transfer panel of a thermal transfer sheet, wherein printing the image-wise security feature is performed via a separate printing technique than printing the image, and the image-wise security feature provides a visual effect that is distinct and distinguishable from the image;
- and
- providing a uniform top coat above at least the image by printing the uniform top coat to the target from a protective mass transfer panel of the thermal transfer sheet, wherein the image-wise mass transfer panel and the protective mass transfer panel are disposed above a releasing sub-coat, and a first portion of the releasing sub-coat that is disposed beneath the image-wise mass transfer panel is altered with respect to a second portion of the releasing sub-coat that is disposed beneath the protective mass transfer panel.
