Abstract:
An uncoated recording medium includes a blend of hardwood fibers and softwood fibers. The total fiber content is at least 80 wt % of a total wt % of the uncoated recording medium. A filler is present in the uncoated recording medium in an amount ranging from about 3 wt % to about 10.2 wt % of the total wt % of the uncoated recording medium. The uncoated recording medium has i) a weight ranging from about 50 g/m2 to about 70 g/m2, and ii) a machine direction Lorentezen & Wetter 5 degree bending stiffness ranging from about 0.19 mNm to about 0.27 mNm and a cross direction Lorentezen & Wetter 5 degree bending stiffness ranging from about 0.09 mNm to about 0.12 mNm, and iii) an ISO brightness of at least 86.
