There is grain in papers. 

Grain forms in paper because of the characteristics of the process of manufacturing of paper. 

Most of the timber fiber used as the raw material for paper are thin and long fibers and grain in the paper forms in the direction of the flow of these fibers. 

When the paper is first manufactured, the grain is in the same direction as it is manufactured in the format of long roll. However, cross-directional grain (CD) and machine-directional grain (MD) are generated depending on in which direction this long roll of paper is cut into. 

• Method of determining the paper grain

Methods of determination of the paper grain include ripping, bending, soaking in water and viewing by reflecting light. However, it is very difficult for ordinary persons to make such determination. The simplest and the easies method is to check the ‘label’ attached to the packing paper.

• Origin of the term, paper

The term paper originated from Papyrus of ancient Egypt. However, there are differences in the concepts and origin of the term paper. Papyrus was made by peeling off the bark of the papyrus plant and thinly filleting the internal core material of the plant, which are then adhered in plate form. As such the manufacturing method differ totally from that of current paper. However, since it is used for writing, English speaking countries use the term Paper, France and Germany use the term Papier, Spain uses the term Papel and Sweden uses the term Papper on the basis of the term Papyrus as the origin of these terms.

• Origin of paper

Conditions of ‘paper‘ are as follows:

Firstly, its configuration must be thin and flat. 

Secondly, the raw material is plant fiber that has been disentangled individually. 

Thirdly, it has weaved structure, that is net-like structure, for the scattered fiber.  

Fourthly, after having dispersed the fiber in water, it is scooped up by using strainer and water then drained out. 

The above 4 conditions are exactly the same as the format invented by Chaeryun in 105 AD. 

The inventor of paper is Chaeryun during the Pre-Han Dynasty in China. This stems from the description in the Chaeryun Section of the literature in the Post-Han Dynasty that, ‘Chaeryun made paper by using inner bark of tree, flax fiber, fishing net and rag cloths, and dedicated it to the Emperor in the 1st year of the reign of Yuanheung (105 AD)'. However, paper made in more primitive form by using hemp plant and rag cloths was used substantially earlier than the era of Chaeryun and was gradually improved into the form that resembled the current form of paper. Chaeryun, nonetheless was the first to discern the importance of paper and systemized the use of paper by collecting and organizing information on paper scattered throughout out China as the first advocate of paper. In addition, since he developed and experimented raw materials to improve and completed the paper with systematic structure, it can be deemed that the historical significance of the development of paper by Chaeryun is enormous.
