ALPHABETICAL LIST OF PAPERS 117
Cartridges.—Strong papers, the best qualities are tub-sized, originally made for cartridge manufacture, but now used for cover papers and as cheap drawings.
Casing's.—Comparatively thin brown papers, used for lining cases, crates, etc.
Chart Papers.—Largely used by lithographers for map and chart printing. Machine-made, the best qualities are all-rag, tub-sized, with smooth surface. Must be strong, pliable, tough, resistant to wear, and at the same time a good printing surface is essential. The manufacture is arranged so as to avoid subsequent stretch.
Cheque Papers.—Good quality of paper, specially made for strength, usually all-rag. Special watermarks may be employed, or protection from fraud is obtained by special printing. Other cheque papers contain chemical compounds which render alteration or erasure easy of detection. The means adopted for erasure cause chemical combinations which alter the colour of the ink, or develop chemical change which discolours the paper.
Chromo Papers.—Fine coated papers for colour lithography, having a thick coating on a good body paper, finished dull or with a good surface. Usual sizes, medium, royal, double crown, imperial. The weights listed are usually those of the uncoated paper.
Cigarette Papers.—Tissues of finest quality, wove or laid, thin, strong, free from loading and taste, and must burn easily. Ropes form the basis of the paper, fine beating being essential. Some papers have chemical additions to the pulp in order to ensure even combustion.
Cloth-lined Paper.—Cotton cloth, equivalent to scrim or common muslins, according to quality, having paper facing. Cloth-centred paper has thin paper pasted on each side, while cloth-backed papers are of better quality, with a fair cloth on the back. Useful where much handling is required. Cloth-lined cards (sometimes described as linen-lined) are thicker substances than the papers. Surface enamelled cloth-lined cards are first made as cloth-backed cards and 'then enamelled with the coloured coating and plate glazed.
