Papers, ContinuedPaper sizePaper is manufactured in industry standard sizes. Countries that use themetric system of measurement have different standards than the UnitedStates. If you buy paper outside the government supply system in a foreigncountry, make sure you understand its unit of measure before you order.Paper surfacesPaper surfaces range from slick to rough. Some papers have a right andwrong side or two different surface textures. An excellent paper surfacecontributes to the professional appearance of an end product.Paper receivesa surface as it passes through manufacturer’s surfacing rollers when the paperis either cold or hot. Hence, the terms cold-pressed (CP) and hot-pressed(HP).HOT-PRESSED PAPER:Hot-pressed paper has a smooth surface. Alsocalled plate-finish or high-surfaced, this is the family of paper you shouldselect to do tight renderings in pen and ink, most calligraphy, and artintended for reproduction. Hot-pressed paper is not a good choice for pencil,pastels, or any media that requires roughness to deposit pigment. Hot-pressed paper is less absorbent and more dense than CP paper.COLD-PRESSED PAPER:Cold-pressed paper has a medium to roughsurface. The roughness of the surface is called tooth. Papers with tooth willbreak up most strokes. The rougher surfaced papers such as coquille boardbreak strokes up enough to have the resulting art photographed as linedrawings. Papers with rough surfaces do not reproduce halftones well.Cold-pressed paper can present lighting problems when you use them for artintended for photographic reproduction. Most general drawing and practicepads and newsprint are made from cold-pressed paper. CP paper is moreabsorbent, therefore, more affected by humidity than HP paper.HumidityPaper is affected by humidity and dryness. Paper surfaces absorb moisturefrom the air making the surface soft and easily scarred. The paper will belimp and tend to wrinkle and curl. Heavy-handed pressure on paper during ahumid day scores or gouges the paper surface. Dry air dries paper out. Itbecomes brittle and creases easily.Continued on next pagel-5
