Dye arrangement
*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.

Shades can be created from the overlapped parts in any given ratio. For example,
by specific combination ratios for brown, olive and gray, any desired shade can
be obtained.
The work front of paste making knows the creation of gray-browns and olive-browns
are particularly difficult. However, the OCS facilitates those difficult shade
creations being carried out smoothly.
With conventional color matching using 3 or 4 dyes in combination, an extra
dye was required for the creation of gray-brown or olive-brown, compared to that
by the OCS. More care was needed in the combination of the 3 colors, and color
deviation was caused more readily.
To give a specific account, 3 'single' colors are placed at the center of
each range. In other words, as shown in Fig.-1, all shades are divided into the
range of brown, olive or gray. Multiple alterations are possible in the setting
of the basic 'single' color at the center of the circle as well as the dye combination
ratios, to create desired shades.
With dyes organized based on these 3 colors, brown, olive and gray, exact
shades can be created to match any sample colors (Fig.-2).

In the age of QR, the process of color matching as the biggest drag on QR, should
inevitably face a renovation. Working hours have been extended in factories without
color kitchen systems. Programming has become complicated in factories with color
kitchen systems.
With conventional color matching methods, tremendous time and effort are required
for sample making.
On making one shade with disperse dyes, if there are 10 people, there will
be 10 variations of a recipe. That is what the problem is. Red, for example,
varies so much that in the case of additional orders, the slightest shade alteration
could be the cause of complaints.
Enormous effort is also required for the creation of strike-offs by conventional
methods. 5 combinations with 8 base-colors create 40 shades. With the acceleration
of 'small-lot, multiple design' production, shade creation becomes more and more
vexatious and complicated. Even with the volume-zone production of 1-5 mil. m² /month,
such as seen in Indonesia, operation is interrupted with printing pastes running
short.
Any interruption will certainly lead to a faulty result. The OCS helps eliminate
such a waste of time.
