Presentation is about manufacturing of Rubber Stamp.

1. Manufacturing of Rubber Stamp
Rubber was discovered in the Amazon River
Basin in 1736 by the French explorer Charles
Marie de la Condamine. Cubes were made of
the substance and used for rubbing out lead
pencil marks, but the material was unstable—
when the temperature rose, the cubes turned
to jelly. This difficulty was solved in 1839 by
Charles Goodyear. Some years before,
Goodyear had begun pondering this problem
with rubber, and he was determined to solve
it.

2. Raw Materials
Rubber stamp manufacturers do not produce
the elements that make a rubber stamp
directly from raw materials. Raw materials
include latex rubber, wood for the mounting
blocks, adhesive-backed padding that is
placed between the rubber and the block, and
adhesive-backed labels. All of these items are
produced by specialty manufacturers who
supply them to rubber stamp makers

3. Design
Designs for rubber art stamps originate at the
hands of a variety of artists. Large-scale
manufacturers of rubber stamps use original
art and hire freelance artists to produce
unique designs that are copyrighted by the
artist and manufacturer. Some makers use
existing artwork produced by name artists
whose artwork—in rubber stamp form—is
then uniquely available from one
manufacturer. Some rubber stamp companies
will also produce custom designs from artwork

4. Usually, this information is provided to fit a template or a
specified word or letter limit so that multiple stamps can be
produced at once, despite the unique contents. Almost any
kind of artwork can be produced in rubber stamp form.
Another rubber stamp revolution has been developed by
manufacturing large blocks with families of words (like
names of flowers) or greetings (such as "Happy Birthday"
repeated in a variety of lettering styles); these blocks are
used by stampers to make greeting cards, wrapping paper,
and other personal products with a theme or message. By
giving classes and showing hobbyists clever ways of using
these products, manufacturers fuel demands for their
creations.

5. The Manufacturing
Process
After a rubber stamp design is selected for
manufacture, a drawing of the design is
photographed, and multiple copies of the
image are transferred to an aluminum plate.
The plate is then bathed in acid that eats
away the exposed metal so the design is
etched or raised above the plate.
The engraved plate (a positive image) is
placed on a sheet of Bakelite, a registered
brand of resins and plastics that can be used
to produce finely detailed molds, in the rubber

6. Quality Control
Because so much of the rubber stamp-
making process is done by hand, quality
control is built into the process. Each laborer
sees the work of the previous handler, so
substandard stamps can be removed
anywhere in the process. Quality is also
ensured by using only the finest materials.
Manufacturers use 100% Goodyear rubber
and maple blocks that are often superior to
furniture quality maple. Adhesives used for the
adhering material and the indexes are chosen

7. The Future
The future of rubber stamps is both practical
and fun. Stamps used by businesses will be
required in many kinds of applications until a
paperless society is truly achieved. Other
practical applications like signature and return
address stamps are also not likely to be
replaced by computer applications in the near
future. As for art stamps and the rubber stamp
hobby, this interest appears to be thriving as
stampers seek to create individual cards,
letters, communications, and keepsakes that
