would heighten similarities and flatten differences.
The investigation results show almost linear shift towards the area of achromaticity
for handsheets made from the fibers before and after flotation with the increasing time of print ageing.

Having 5nm optical resolution and wavelength range of 350nm-1100nm, it precisely measures color, achromaticity
, whiteness and yellowness.
