The water-based and energy-curable inks being used by Polytex are currently being integrated with new products such as 7.4295, a new flexo primer for use with UV-curable inkjet printers.
"7.4295 is an excellent fixative that is resistant to water, mild detergents, and even some solvents," says Bob Waddington, technical service manager at Polytex. "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."
According to the company, this new Polytex product provides a solid foundation for sharp, product-resistant printing, and 7.4295 can be applied to many conventional substrates to control costs.
The product is a water-based, flexo-applied primer suitable 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. "Images printed on top of 7.4295 looked identical to images printed with a conventional flexo printing press,” adds Waddington. "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."
A 4-6 BCM anilox roller is recommended for most applications. 7.4295 dries fast but does not harden up on anilox rollers or tint sleeves if left idle for a few minutes. 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.
