Information about the typographic sizes
All enterprises who use printing and visual printing technology work with the paper sizes defined by the international standards which are valid in every country (except for the USA, Canada and some other American countries) an in all of Europe.

„A” sized series:: The size of the A0 paper sheet is 841×1189 mm. Its area is 1 m².
The commonly used size A4 (210x297 mm), is the A0 paper cut in half four times.

„B” sized series: The usual starting size is (B0) 1000×1414 mm. The longer side is usually rounded down to 1400 mm. In the past it was marked as BB. Now the rounded down size is called „B”.

„C” sized series: This less used size stays in the middle between the other two sizes, its starting size is 917×1297 mm. It is commonly used as the size of envelopes.

Paper types and their characteristics
The presentation of the different paper types and their usual characteristics

The products of the paper industry (papers, cardboards and plates) can be categorized based on the following factors:
- the ingredients of the fiber materials (for example Contains cloth cellulose, contains cellulose but no wood);
- the weight per m2 (for example Paper until 180 g/m2, cardboard until 400 g/m2, plate above 400 g/m2);
- method of production (made on an even- or cylinder-sieved paper machine, has one layer, is impregnated etc.);
- the design of the layer (one, two, three layers, multi layered, glued etc.);
- the glue (not glued, glued in the material or on the surface, writable etc.);
- the color (white, colored, natural etc.); the smoothness (not smoothed, softly or strongly smoothed, glazed, smooth on one side etc.);
- other characteristics (watertight, fattight, steamtight, colorkeeper etc.);
- the form of appearance (roll, bale, ream etc.).

The most common groups of paper, cardboard and plate and the type of their material

WRITING PAPERS
This defines the writing and printing papers.
It contains the types of paper used for writing in the offices and private life.
Their common trait is that they can be grinded very well, this increases their ability to be written and erased upon, their overview is very beautiful and even.
They may contain glue which furthers their write-ability (it ensures that the ink does not flow all over the paper and to the backside of the paper). Since the filling materials decrease the amount of glue in them, the writing papers contain either no amount or a very small amount of filling material, their surface is smoothen.
Typical types for example: papers of documents, bank post, accounts (business paper), offices, color, floor posts, carbon paper, typewriter paper, paper for saddelstitcher (typical paper for school sheets), and for musical notes.

PRINTING PAPERS
Common traits of the printing papers are the soft touch, flexible hold, and most importantly the good printability. They contain either no glue or a very small amount.
They contain mostly wood polish, the finer printing papers contain cellulose, but woodless or cloth-containing printing papers can be produced as well.
The various types of printing paper fit to the printing process in which they are meant to be used.
Typical types for example: Newspaper, amplified newspaper, paper for novels (best used for printing books), posters, Bibles, smoothen printing paper, subwoofer paper, artistic printing paper, Off-set paper without wood, paper for maps.

MAGAZINE PAPERS
Contain wood, if the technology allows it, they can be used for high, off-set, deep and sieve printing. They can be purchased in sheets and rolls. Among them the following qualities of paper can be distinguished:
SC (supercalandered), MFC (Machine Finished Coated), LWC (Light Weight Coated), MWC (Medium Weight Coated), HWC (Heavy Weight Coated), WFC (Woodfree Coated, 1x, 2x, or 3x coated), Recycle paper.

PACKAGING PAPERS
Natron packaging paper, Superior packaging paper, fine packaging paper, semi fine packaging paper , Lignocell paper, photo adjusting paper (black packaging paper), silk paper.

TECHNICAL PAPERS
Technical natronpaper, polishing paper.

SPECIAL PAPERS
Money paper, stamp paper, raw copying paper (with positive and negative function), blotting paper.

CARDBOARD PAPERS
Postcard paper without wood, cellulose cardboard without wood, off-set cardboard, deep printing cardboard: Cromocardboard, hand-deckled cardboard, game card cardboard.
