The Digital printing revolution continues to take ink jet technologies into new industrial printing markets. The new products and concept printing systems recently introduced over the past several years, especially at DRUPA 2000 and other recent industry trade shows, exemplify this point as well as the convergence with conventional print applications. The digital market is seeing the emergence of new innovative ink applications, which are traditionally supported by conventional ink manufacturers, like Flint Ink. An example of this is the use of UV curable ink jet inks. The reason for the development of newly innovative inks is that end users are demanding to be able to print on more difficult substrates such as chrome and UV coated paper stocks, vinyls, polycarbonates, polypropylenes, polyethylenes, and glass. These new requirements are also making it more challenging since most of the substrates do not have an ink jet receptive coating on its surface. This makes the ink formulator's job more challenging. This paper discusses some of the recent and emerging industrial and commercial printing applications utilizing ink jet printing technologies, target substrates, and types of inks suitable for each application.
