Abstract
A media for digital high speed inkjet web press printing has a CD residual tensile energy absorption index greater than 300 J/Kg. The media includes a paper base having a MD/CD tensile stiffness index ratio of less than 2.0 and a tensile energy absorption index of greater than 500 J/Kg. The paper base includes a mixture of fibers having a softwood fiber to hardwood fiber ratio within a range of 3 to 7 to 7 to 1, an internal starch having a cationic starch to fiber ratio greater than 1.0%, and a filler within a range of about 1.0% to about 12.0% of paper base weight. The media further includes an image receiving coating on a side of the paper base.
