Jan 12, 2015
Let’s talk paper. Digital papers to be specific. They’re an entirely different animal than papers for offset printing. And why shouldn’t they be. The printing equipment used is totally different as well—ranging from small office copiers to high volume, high heat color production machines.
The digital printing process itself faces several paper/substrate challenges. First, the media must run smoothly through the press. Second, it must adhere the ink/toner. And third, the digital paper and printing must withstand numerous bindery applications.

Precision Sheeting
All paper, whether folio or digital,
must be sheeted. The sheeting
process is critical to the runnability of
the paper. Having sharp, clean cut,
flat edges are critical to a digital
press’ up time.

All About the Surface
We can’t tell you how we do it – the
processes are proprietary – but we
can tell you why our papers get better
results. It’s all about the surface.

Surface Treatments
Though originally developed for
performance in offset grades,
Mohawk’s proprietary Inxwell
technology creates an easy running
sheet with a tight surface and
exceptional toner or ink adhesion.
This treatment can be found on
Mohawk Options, Navajo and a
derivative on Mohawk Color Copy.

Moisture content
Typical paper is produced to an
absolute moisture content between
4.0 and 6.0%, meaning 4 to 6% of
the paper’s total weight is made up of
water.
