  resistance than the standard sample to removal by abrasion of 
  typewritten characters.

General appearance: Paper shall conform to the standard sample(s) 
  adopted by the Government.

 Unless otherwise specified, the following is automatically waived when 
  printing or duplicating is to be accomplished on commercial contract
Sizing: Paper shall be surface-sized with high-grade animal glue and 
  internal-sized suitable for satisfactory printing on both sides of the 
  sheet on high-speed offset presses equipped with continuous flow or 
  brush dampening systems.
Color: Shall match the Government's standard sample for color. A 
  deviation of DE(CIELAB)=3.0 from the color standard is allowed.
Curl: Paper shall lie flat with either no tendency to curl or with a 
  curl which can be overcome under reasonable working conditions.
Surface: Shall be free from lint, fuzz, or any particles which will 
  pick, lift, fluff, or pile on the blanket under normal press 
  conditions.
Size and trim: Sheets: Paper shall be furnished in the size(s) ordered 
  and shall be flat, trimmed square on four sides with clean smooth 
  edges, and evenly jogged. A tolerance of 2 mm (\1/16\ 
  inch) shall be allowed except for sheets 216 by 356 mm (8\1/2\ by 14 
  inches) or less; then a tolerance of 1 mm (\1/32\ inch) 
  shall be allowed. Successive sheets within any package shall not 
  differ from each other by more than 0.5 mm (\1/64\ inch). Paper with 
  the long dimension 813 mm (32 inches) or less shall be considered 
  square if the variation does not exceed 1 mm (\1/32\ inch); over 
  813 mm (32 inches), 2 mm (\1/16\ inch).
Watermark: Shall be the seal of the United States, with four stars and 
  the year of manufacture, on a basis of four times on a sheet 432 by

  clear and legible. When viewed from the felt side of the sheet, the 
  design shall appear as illustrated, but in proper size. Full size copy 
  will be supplied upon request. (The 165 g/m \2\ paper shall not be 
  watermarked).

    \1\ This grade is typically a low Government usage paper and 
currently not readily and/or economically available with postconsumer 
recovered fiber content. If a postconsumer recovered fiber content is 
desired in the paper, that number will be stated in the procurement 
document. Note, recovered material (cotton/linen) is not a postconsumer 
recovered fiber.
