Color: Shall match the Government's standard sample for color. A

Curl: Paper shall lie flat with either no tendency to curl or with a
curl which can be overcome under reasonable working conditions.
Coating and surface: Shall be uniform, free from mottle and any
particles which will pick, lift, or pile on the blanket under normal
press conditions.
Size and trim: Rolls: Roll width and diameter shall be as ordered. A
tolerance of 2 mm (\1/16\ inch) shall be allowed for width
and 26 mm (1 inch) for diameter.
Roll winding: Roll paper shall be tightly wound at even tension and
shall not contain more than the specified maximum number of splices
per roll. The number of s;lices permitted per roll is determined by
the roll diameter as ordered. On rolls 1,016 mm (40 inches) or less, a
maximum of three splices per roll shall be allowed. On rolls over
1,016 mm (40 inches), a maximum of four splices per roll shall be
allowed. Splices shall be neatly and securely overlap-pasted and made
with a repulpable adhesive which will not permit the splice to
separate. The adhesive may be applied from a tape form backing,
provided the backing is removed, leaving only the adhesive component
on the splice. The adhesive shall not cause the splice to adhere to
adjacent laps. The tails of the splices shall be neatly and evenly
removed without damage to adjacent laps. Splices shall be flagged at
both ends with projecting colored markers, not pasted to the splice,
or otherwise clearly marked.
Pressroom conditions: The bulk of this paper will be used in air-
