I have a roll of Type 2 paper. Historically, it has been somewhat yellow (lab: 94.7, -1.6, 9.8). Recently, I saw a noticeable change in color from yellow to white (lab 95.7, -0.3, 4.5). This roll has sat on the printer for a while, covered by plastic. I’m not entirely sure if it was always yellow or if it turned yellow.
Does this paper naturally turn yellow over time? Did I get a bad roll of paper? Should I be storing it differently?
