This new Polytex product “provides a solid foundation for sharp, product-resistant printing,” said Bob Waddington, technical service manager at Polytex Environmental Inks. 7.4295 is an excellent fixative that is “resistant to water, mild detergents, and even some solvents.” One of the main functions of the primer is to ensure efficient drying and to create crisp, eye-catching prints that keep clients satisfied and coming back.
In testing the new primer, Polytex found that digitally printed images became completely water-immersible when printed on it. “Images printed on top of 7.4295 looked identical to images printed with a conventional flexo printing press,” Waddington said. This new primer is unique in today’s marketplace, because a relatively thin film provides very robust performance, the kind printers usually associate with gravure-applied primers.
7.4295 is a water-based, flexo-applied primer ideal for UV inkjet printing. It can also run on gravure or rod coaters, and will perform well on BOPP paper and other substrates designed for flexo printing. It is resoluble, and washes up easily with mild anilox cleaners. The primer cures to a neutral finish and is suitable for printing on clear substrates. It will not dull or haze clear film.
