The impact of deinked post-consumer secondary fiber (PCW) on the printability and runnability of an uncoated recycled sheet through printing operations was studied. The PCW was substituted into the base stock (50/50 HW/SW) at levels of 25%, 50%, and 100%; and printed on web fed flexographic and rotogravure printing presses. Tensile strength, brightness, and Δ gloss decreased with the addition of secondary fiber, while opacity, roughness, and bond strength increased. Stretch, tensile energy absorption, and tonal response remained relatively unchanged as the percentage of post-consumer waste increased.
