Types OF Paper
Paper selection is an important element in print projects.
Selecting a paper can often be very confusing; there are numerous different types and brands of paper available today.
When selecting paper, be sure to keep in mind that the choice you make for your project will affect how it the printed
piece is perceived. Before placing a printing order, it is a good idea to request a paper sample for each paper you are
considering for the project.
What Distinguishes Different Papers?
Finish: The finish of a paper is it's surface texture. Uncoated and coated paper have different surface textures.
Weight: The weight of a paper refers to its thickness and is measured in pounds (#). The higher the number,
the more (equivalent) weight a paper has (the thicker/heavier the paper). *See the comparison table for more
information on weights.
Opacity: A paper's opacity is determined by its weight, ingredients and absorbency. A paper's opacity determines
how much printing will show through on the reverse side of a sheet. Opacity is expressed in terms of it's percentage
of reflection. Complete opacity is 100% and complete transparency is 0%.
Brightness: The brightness of a sheet of paper measures the percentage of a wavelength of blue light it reflects.
The brightness of a piece of paper is typically expressed on a scale of 1 to 100 with 100 being the brightest.
Most papers reflect 60-90% of light. The brightness of a paper affects readability, the perception of ink color
and the contrast between light and dark hues.
Types of Paper
Offset: Also known as book or text paper, offset paper can have a coated or uncoated finish. Offset paper is thinner
and lightweight. It is often used for publication interior sheets, brochures & flyers, and letterheads. Common offset
weights: 50#, 60#, 70#, 80#, 100#. Bond: Bond or writing papers are most often used for letterhead.
The most commonly recognized bond or writing stocks are:
Cover: Cover stocks are heavy in weight, rigid and not easily folded. These papers are generally used for publication covers,
business cards, greeting cards, folders, and postcards. They can have coated or uncoated finishes. Common weights for
cover stocks include: 65#, 80#, 100#, 120#, and 12pt.
Tag: Tag paper is a dense grade of paper that is strong, durable, and water resistant. Tag paper is typically used for hanging
tags such as store tags on clothing or other products.
Index: Index paper is a stiff, not too thick, inexpensive paper with a smooth finish. It is often used for index cards and folders.

while less absorption makes poor quality of carbon paper which is used many a time.

Writing Paper (Note book)
it will be perceived as having less number of pages.
Another important factor is cobb,
since writing ink must go into the paper instantly and dry.
Used For : Used for note books.
Preservation of aroma and perfection against attack of external environment to the packed contents
are also important qualities of the subject papers.

external environment to the packed contents are also important qualities of the subject papers.
Used For : Used for food packagings and other special wrapping applications.
paper used for application of gum should have adequate porosity. Good printability, compressibility,
absorbency and ink hold out give satisfactory printing.
Used For : Used for printing of labels in multi colour.

Time Carbon (OTC) Paper
Used For : Mostly used in multi-part continuous stationery.
Extrusin Base Paper
These papers are made in soft loosely
felted conditions in order to obtain max. absorbency
so that they can take
water quickly and hold it after absorption. Made with high content of Alpha Cellulose or Rag %, they are treated
with wetting agents to improve absorbency.
Used For : Used as Paper Towels, napkins, toilet tissues etc.
