The purpose of this study was to determine the effect of padded roller speed (RPM) and pressure (PSI) on the color of digitally printed cotton fabrics. Single layers of double-knit cotton fabric were padded at speeds of 20, 40, and 60 rpm and pressure levels of 5, 15, 40, 60, and 70 psi using a 36” wide padder. The padding solution consisted of alginate, soda ash, urea, and distilled water. Color readings were taken using a spectrophotometer. Results indicated that roller speed and roller pressure both had an effect on the shade depth of the fabric.
