Let’s learn How Self-inking stamps are made:
·       First a design has to be selected and photographed. Numerous copies of the image is then transferred to an aluminum plate. Next acid is poured that eats away the extra metal so the design stands out above.

·      Then the carved plate is placed on bakelite in a vulcanizer. Huge amount of heat and pressure is given in the vulcanizer; a negative mold is left behind by the carved plate in the resin sheet. A rubber sheet is then kept over the mold and is heated to create the final image. Then it is removed for cooling.

·    Sheets of photopolymer are used instead of rubber. Here they are applied in liquid to a transparent negative which is covered by a thin plastic and placed in a photo relief printing machine. This machine in turn exposes the resin and negative to UV rays which in turn produces the image. Afterwards it is dried.

·     The labourers required for manufacturing a rubber stamp should be highly skilled. Adhesive sheets are pressed into the newly formed rubber sheets and are cut into shapes by scissors.

·     The back is then attached to a strong object like the wood for support. The blocks are of normal sizes. Maple is common as it is very strong and would be firm under a lot of pressure. Even temperature changes would not distort it. The adhesive is placed on the top of the block and the stamp design is printed.

·      Once the process is finished, the stamps are divided and stored separately. They are packed and shipped according to orders.
