Design Production: Paper Types

Paper may be classified into seven categories:

  • Printing papers of wide variety.
  • Wrapping papers for the protection of goods and merchandise. This includes wax and kraft papers.
  • Writing paper suitable for stationary requirements. This includes ledger, bank, and bond paper.
  • Blotting papers containing little or no size.
  • Drawing papers usually with rough surfaces used by artists and designers, including cartridge paper.
  • Handmade papers including most decorative papers, Ingres papers, Japanese paper and tissues, all characterized by lack of grain direction.
  • Specialty papers including cigarette paper, toilet tissue, and other industrial papers.

Coated paper is paper which has been coated by a compound to impart certain qualities to the paper, including weight, surface gloss, smoothness or reduced ink absorbency. Kaolinite or calcium carbonateare used to coat paper for high quality printing used in packaging industry and in magazines. The chalk or china clay is bound to the paper with synthetic viscofiers, such as styrene-butadiene latexes and natural organic binders such as starch. The coating formulation may also contain chemical additives as dispersants, resins, PE: to give water resistance and wet strength to the paper,[1] or to protect against ultraviolet radiation.

Bond paper is a high quality durable writing paper similar to bank paper but having a weight greater than 50 g/m2. The name comes from it having originally been made for documents such as government bonds. It is now used for letterheads, other stationery and as paper for electronic printers. Widely employed for graphic work involving pencil, pen and felt-tip marker, bond paper can sometimes contain rag fibre pulp, which produces a stronger, though rougher, sheet of paper.

Laid paper is a type of paper having a ribbed texture imparted by the manufacturing process. In the 19th century its use diminished as it was largely supplanted bywove paper. Laid paper is still commonly used by artists as a support for charcoal drawings.

Wove paper is a writing paper with a uniform surface, not ribbed or watermarked. The papermaking mould's wires run parallel to each other to produce laid paper, but they are woven together into a fine wire mesh for wove paper. The originator of this new papermaking technique was James Whatman (1702–59) from Kent, England.
