I, Some concepts about paper in general
Paper is a thin material produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets. It is a very versatile material with many uses; whilst the most common one is for writing and printing upon, it is also widely used as a packaging material; in many cleaning products; in a number of industrial and construction processes, and even as a food ingredient – particularly in Asian cultures.
It and the pulp papermaking process is said to have been developed in China during the early 2nd century AD, possibly as early as the year 105 A.D., by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BC in China. The modern pulp and paper industry is global, with China leading its production and the United States right behind it.
Besides category by purpose; basically, paper is classified by name and weight:
Name: there are several kinds of common paper and specific paper which will be shown latter in this thread.
Weight: Is the weight of paper calculated by gram per square meter (g/m2). In Europe, and other regions using the ISO 216 paper sizing system, the weight is expressed in grams per square meter (g/m2 or usually just g) of the paper. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying “basic sizes”, before the paper is cut into the size it is sold to end customers.
Paper weight is usually variant from 80-300 gram depends on types of paper. Printing paper is generally between 60 g and 120 g. Anything heavier than 160 g is considered cards. The weight of a ream therefore depends on the dimensions of the paper and its thickness.
Normal paper used in photocopying or printing is usually 70-80 gsm.
The thickness of paper is often measured by caliper, which is typically given in thousandths of an inch in the United States and in thousandths of a mm in the rest of the world. Paper may be between 0.07 millimeters (0.0028 in) and 0.18 millimeters (0.0071 in) thick.
All size in the Series A, B and C are rectangle shape with the ratio of 2 sides is the square root of 2, approximately 1.414. The area of A0 paper is 1m².
– The 2 sides of A0 are therefore determined as 841 × 1189mm
– The size of the blocks are in the order determined backward, smaller size has an area equal to 50% of previous size (divided by cutting along the line parallel to the short side).
II, Some common types/brand of paper (typically for pop-up cards making):
Various in weight and texture, paper is divided into several types, suitable for different kinds of pop-up cards:
1, Plain and thin paper (60-90gsm): Ford paper
This type is very popular and mainly used to print the template/ pattern, or only to draw. However, pop-up cards with many details can use this one to make the process easier.
2, Plain but thicker (120-180gsm or heavier):
A, This type can be found easily in any stationery shop anywhere. Typically Kishu paper is most common with a huge range of vivid color and weight. Kishu paper can be bought in Korea or Japan. Due to the variety, this one is useful in almost types of pop up cards
B, Canson also has plain paper products. This type is thicker and can keep the form very well. Thus this is usually used in cards making, no matter the price is a bit expensive. The surface of Canson is also suitable for drawing, sketching, therefore many artists choose this brand. Canson paper sometimes has veins which makes pop-up products look more luxury.
3, Texture paper
A, Conqueror Paper, of which origin in London, England, is another popular brand. Characterized by veins along the paper, this type is good at form-keeping. Being thicker and having deeper color, it’s best fit the cover of a cards. Whilst, some light colors of this brand like cream color is a good choice when cardss made by white paper is becoming uninteresting. However, sometimes vein is the problem due to the fact that they makes your cut not precise.
B, Thai Basil paper is also a special paper with vein along but thicker and heavier. The color is limited and mostly deep but when you need a thick paper to keep the form in 90 degree cards, it is still a good choice.
