1. PAPER SEPCIFICATIONS a. ANSI COMPLIANCE: All papers must meet or exceed the ANSI Z39.48-1992 standard for permanence, ensuring suitability for library and archival use. b. CHEMICAL AND PHYSICAL PROPERTIES: i. Lignin Content: No more than 1% lignin by weight, corresponding to a Kappa number ≤ 7, ensuring resistance to yellowing and degradation. ii. pH Range: Neutral to slightly alkaline (7.0 to 10.0), which minimizes acid-related decay. iii. Buffering Agents: Must contain at least 2% calcium or magnesium carbonate filler to neutralize acids over time. iv. Acid-Free: Guaranteed to prevent degradation caused by acidic components. c. GRAIN ORIENTATION: Paper must have a lengthwise grain, improving stability and handling during processing. d. MANUFACTURING PROCESS: Multi-cooking and chemical treatments are required to eliminate grayness and minimize color changes. e. TRIM QUALITY: Sheets must be precisely guillotine- or rotary-trimmed on all four sides, ensuring uniformity and clean edges. f. PERFORMANCE: The paper should produce sharp, clear, legible copies without linting, ensuring smooth operation in printers and copiers. g. GRADE: Papers must be at least Number 4 Grade, as defined by industry standards such as, TAPPI Paper Guide. h. DIMENSIONS: All papers must be within industry tolerance factor or zero (0) plus or minus (+-) 1/32" for rotary or guillotine cut. Variances within ream of more than 1/64" will be considered as sufficient cause for return of all unsatisfactory material, by lot or production run, of purchase order. i. PACKAGING: All paper must be cut, and ream wrapped at the mill in moisture proof paper with a printed label attached setting forth the mill brand, type of paper, substance weight, grain and number of sheets therein. j. WEIGHT TOLERANCE: Any variations above or below the basic weight specified shall not exceed +/- 5%. k. COUNT: "Mill Count" 500 sheets per ream shall be accurate for all grades of paper. Verification of mill count will be made by the receiving agency and deliveries may be rejected for inaccurate count. Shortages will be deducted if the delivery is accepted. l. CURL: Paper having a curl which cannot be overcome under reasonable working conditions will be rejected.
