A practical approach to streamlined printing |

1. Dye arrangement for polyester printing |

1,000 colors created with 2 disperse dyes
*The images below are examples of shades created by
the OCS (Oyabu Color System). The base-colors used in the OCS are no more than
11. More than 1,000 shades can be promptly created from 3 base-colors, brown,
olive and gray.

The promotion of the OCM could not be fulfilled due to the shortage of hands
at BASF Japan. It was in Texmaco, a major factory in Indonesia where I served
as technical adviser, that the color management system under the name of the
OCS had been put into practice. That was the first step for the spread of the
OCS. I was confident that the OCS, or OCM, was theoretically effective, however,
its practicality on the work front was yet to be confirmed by the actual implementation
at Texmaco, which produced satisfactory results.
Through 7 years of the OCS implementation at Texmaco, with some modification
made for better handling, the prompt creation of more than 1,000 shades from
2 base disperse dyes was finally accomplished.

Color kitchen systems for the fully-automatic preparation of printing pastes,
which was first developed in Europe around 1980 and later in Japan, was successful
in its obviation of man-made errors during color matching by automation, however,
conventional expertise still had to be depended upon for the selection of dyes
and combined thickeners.
In order to further rationalize and diversify the creation of shades at the
same time, the selection of dyes and thickeners should be streamlined and the
number of paste preparations limited. And should these be achieved, the simplification
of the structure of color kitchen systems and even the facilitation of manual
color matching can be expected. It should be well understood that the OCS stems
from a way of thinking.
