Printing and Printing Ink


                                                     Printing and Printing Ink

The definition of printing in a printing glossary is as follows.

The technology of making individual plates customized for each typescript, spreading ink over these plates then applying
pressure over the inked areas to transfer the ink onto large quantities of paper or other surfaces.

These 5 items mentioned above, "typescript", "plate", "ink", "pressure (pressure from the printing machine)", "paper or
other surface¡±, are called the 5 essential factors of printing.

This definition applies to printing ink and is completely different, functionally and fundamentally, from writing ink. The
composition of printing ink is more similar to oil paint or oil colors but contrarily to paints or dyes, which are applied
directly onto the surface using , brush or spray, printing ink consists of a more complex process of going through a printing
machine, plate and blanket before actually being printed onto a surface. Another major difference is that considerably thinner
films of printing inks are used in comparison to paint or dyes.

Whereas paint is applied to protect the substrate and to enhance its appearance and dyes are applied for artistic creation, the
main purpose of printing ink is to reproduce mass quantities of different typescript. Accordingly, the 5 essential factors and
their interconnected factors need to be regulated and the proper preparation of printed matter should not be neglected.
