The initial roll temperature will affect the final camber substantially. The hotter roll will be geometrically more stable compared to the colder roll. More specifically, for a 100 s pass the camber increases by ~6 μm in the case of 340 Κ roll initial temperature, and by ~4 μm in the case of the 380 Κ roll initial temperature.
