PAPER WEIGHT

Paper is measured in pounds per five hundred sheets (one Ream of paper) of a regular size of sheet supported the cluster or class of papers the grade. If five hundred sheets of this size weigh 20lbs., then the paper is assessed as a 20lb bond. Heavier and lighter stocks can clearly be thicker or dilatant than the 20lb.

paperweight is a small solid object heavy enough, when placed on top of papers, to keep them from blowing away in a breeze or from moving under the strokes of a painting brush. While any object can serve as a paperweight, decorative paperweights of glass are produced, either by individual artisans or factories, usually in limited editions, and are collected as works

Of fine glass art, a number of that area unit exhibited in museums.

USES OF DIFFERENT PAPER WEIGHTS

Even though it’s the most confusing, the U.S. basis weight defines the paper types familiar to most Americans. These include bond, book, cover, index, tag, and text. Each of these types can encompass a variety of weights and is best suited for particular uses.

1: Bond paper (16, 20, 24, 28, 32, and 36 pounds)

Also called paper, this is the type of paper weight for printer paper and copier paper.

In addition to everyday printing, it’s most often used for letterhead and stationery. Lighter-weight bond paper is ideal for faxes, printing emails, tracing, and use in high-speed copiers. Mid-weight bond paper is highly adaptable and works well for reports, presentations, double-sided printing, legal documents, and proposals. Heavier-weight bond paper also works well for double-sided printing and presentations as well as signs, fliers, contracts, and resumes.

2: Book paper (30 to 115 pounds)

This group comprises coated and uncoated papers of varying thicknesses. Book paper is often used to print books, booklets, catalogs, magazine publications, and posters.

3: Cover paper (60 to 120 pounds)

Regularly mentioned to as cardstock, cover paper is thick and stiff (although as you can see by the pound range, this thickness can vary substantially). It is usually used for business cards, door hangers, menus, invitations, postcards, rack cards, report covers, self-mailers, sketching, and so on.

4: Index paper (90, 110, and 140 pounds)

As the name suggests, this stiff paper is most commonly used for index cards. It’s also mostly used for postcards, tabs and dividers, manila folders, and sketchbooks.

5: Tag paper (100 to 200 pounds)

Highly resistant and fairly stiff, tag paper is used for retail signage, price tags, table tents, file folders, door hangers, direct mail postcards, menus, posters, and time cards.

6: Text paper (50, 60, 70, 80, and 100 pounds)

This type of paper is usually an upgrade in quality over book paper and is most commonly used in commercial printing operations. Uses for text paper may include brochures, letterhead print jobs, stationery, internal memos, and thesis papers.

PAPER WEIGHT MEASUREMENT

The three common ways for specifying paper weight and paper thickness:

  • GSM:

Based on density (g/m^2)

  • S. Basis Weight:

Basis Weight is based on weight (or lbs.)

  • Caliper:

Caliper is based on thickness (inches)

GSM

GSM stands for a gram per square meter and is that the activity unit} of paper measurement.

This is the most simplistic schematic form of paper measurement however it is not the most common use of measurement in the U.S.

US BASIS WEIGHT

Basis weight is based on the weight of one ream, or 500 sheets, of paper in its basic unit uncut size a ream is a traditional unit of quantity used for counting sheets of paper. One ream equals 500 sheets of paper.

The shorthand you may see to denote this way of activity is “lb.” or “#”.

If a paper is delineated as “60 avoirdupois Unit.” that means that one ream of that paper is 60 pounds.

Basis Weight is one amongst the foremost common ways that of describing the weight however it doesn’t build it straight forward to grasp the thickness of a paper.

 

CALIPER

Another kind of paper activity is employing a caliper.

This technique uses a mensuration tool known as a micrometer to live the thickness of paper in points (or pts.). One purpose equals 1/1000 of an in. (or zero.001”).

Caliper measurements are most commonly used to describe card stock thickness.

Cardstock and canopy Stock square measure substitutable and used for comes like postcards, business cards, or door hangers.
