A practical approach to streamlined printing |

1. Dye arrangement for polyester printing |

Multiple color assortments created from 2 base-colors
for smoother printing
Naoharu Oyabu, printing consultant

Mr. N. OYABU |
A color management system called the Oyabu Color System (OCS) rationalizes polyester
printing, with more than 1,000 shades created from 2 base-colors. It has already
been used in many printing factories, mainly in Indonesia. The description of
the system is available below.
The OCS, based on first-hand ideas conceived from working at Daido Maruta
Senko for a rational print color management, was compiled later in my BASF days.

The idea of the OCS has been derived from overlapping of knowledge acquired from
work-front experience at a printing factory and knowledge of dye characteristics
working for a dye manufacturer.
I am the inventor, and the patent has been applied for by BASF Japan, under
the name of OCM.
