DRAWING PAPERS The technical drawing is usually done on paper (made also in the computer) and that role is not always the same. We must differentiate between drawing paper, art papers and papers for use in museum (museological) the latter must be chemically neutral even though it is quite possible, at most, may require some alkalinity, so it does not affect objects that may come into contact with the paper.
drawing papers used in technical drawing are classified as White
: are common stock, have a load of glue and chalk mixture which makes them resistant to moderately absorbing. The ink is irreversible once made a drawing in these roles. Often have variable acidity. The best white papers are slightly alkaline (like paper SCHOELLER) to retard yellowing. It comes in various formats and weights (weight per m2)
Acid-free: are roles in general for printing ink, resistant to yellowing. The characteristic "acid-free" is generic, but some office papers are sold under that label, such as paper Okidata C5000, C7000 and C9000.
Sketch: large format white paper, with a larger load of glue on one side.
tracing: (also called "parchment" or "tailor") are very open frame roles, which allow light to pass through or are translucent. Serve to make drafts and sketches

greater brand paper, or documentary : white paper is high or very high quality, weighing from 70 to 100g/m2, smooth, textured iridis or satin. A great brand is the oldest European factory MAGNANI, but most production is for top quality art paper, card, original artwork, etc., and their quality is a very expensive material. Paper plant
: role is to deal with the sulfuric acid paper fibers, resulting in a very homogeneous mass, which is incorporated then resins, formerly Canada balsam. It is rigid, cracks forming white lines and is highly absorbent of humidity. China ink can be erased with rubber wheels or by scraping (commonly called "Gillette"). Is a paper document and is generally free of acids by an alkalinization process, with a pH around 8. Must be kept very well, because the humidity, however slight, deforms the fibers, the softening resins.
The weight per meter (weight) ranges from 60 g/m2 (light) to 200 g/m2 (extra dense).
Finnish: lightweight tracing paper (40 g/m2) or open weave paper treated with resin cheap. They are very thin, and are often used as a draft. The tracing paper is often treated replace it with some advantage, tracing paper of 60 g/m2. At 30 to 40 g/m2, for use in printing, is often called "Bible paper." Cardboard
: paper are heavyweight (over 110 g/m2) and used for presentation drawings. Cardboard
museological: are high pH, \u200b\u200bwhich is slightly alkaline. The pH is usually 8 or more. Museological papers have a reservation, this means they take longer to acidify, an effect that is evident in the yellowing. Nor have lignin, which affects its tannin content, objects in contact with the paper. The best-known brands are DEKORA, Schöller, WATT, and FABRIANO MUSEUM BOARD. The frequent indication to describe this type of paper is ACID FREE. Those used for technical drawing are very shiny (coated one or both sides, although there are opaque)
Paper graph: is often used in archaeological excavations in mapping. Paper
Japan: paper whose mass is made by soaking a cotton cloth. One of the most used museological materials, because it's not loading any queue or unknown chemicals. Highly absorbent, is not used for technical drawing, but for posters, labels, tabs, wrappers, envelopes, etc. contact with objects. They come in various weights, from paper to cardboard.

polyester, synthetic paper precision drawings or plotted, it comes in rolls with an exact weight of 100 g/m2, and very stable. If the paper gets wet, is not altered.
mention the roles that are not used specifically in technical drawing:
KRAFT paper or book: unloaded a grand role in the mass, but many in a d
and the faces, which is brighter. It is usually very bad paper for museum, white, gray or brown, according to the fiber. It is often used for drafts or wraps. Canson
: textured cardstock for artistic drawing, the name comes from a trademark. Not museum. A brand known is Michelangelo.
colored paper handmade, painted: are just for display, not usually present different museological and takeovers, generally unknown composition.
