Stock: 100% bleached chemical pulp. 

No fluorescent (optical) brighteners shall be added to the 
pulp or paper during manufacture. Fluorescence, due to 
residual white water, broke, or natural fibers, is 
permissible; provided the increase in reflectance, measured 
with and without the ultraviolet component of a light 
source of 3100 Kelvin in combination with a C.I.E. 
(International Commission on Illumination) Z (blue) filter, 
does not exceed 2.0%. 

Note:1 Postconsumer fiber, in any percentage, is 
encouraged, provided that the requirements of this 
Standard are met.

average not less than 70% when measured with a print 
contrast meter. 

Color: The paper in the order (or publication) shall be 
uniform and the color variation shall not exceed 
DE(CIELAB) = 1.0. 

Formation: Shall be uniform. 

Cleanliness: The dirt count for each side of the paper shall 
not exceed 10 parts per million (ppm). No sample sheet 
(600 to 650 cm2 in size) shall contain more than one defect 
with equivalent area of 0.25 mm2 or greater.
