Abstract
The ability to form a raised three dimensional image makes possible the use of
modified processes, inks and substrates in fine art work, such as children's
books, business cards, postcards, and special type printing processes. If the
raised image attains the required height and firmness, it can be used in printing
of Braille characters. Production of three dimensional (3D) images on a
substrate can be accomplished by old fashioned embossing procedures, a
process using hectographic or spirit duplicating masters, or raised Xerographic
printing with thermally intumesced electroscopic powders. It may also be done
employing three-dimensional imaging paper with randomly distributed fibers
with uniformly dispersed unexpanded synthetic thermoplastic polymeric
microspheres, thermographic processes, special printing processes, which work
by building parts of light curable photo-polymer in layers, or heat transfer
printing with thermally-expandable ink layer.
Results from our laboratory show a modified formula of hot melt ink that can be
used in 3D thermal wax printing process to create raised images on the
substrates. An extensive study of thermal behavior of the components of
