Presentation is about the manufacturing process 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

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

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

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
