The Wool Research Association is hosting a two-day advanced course on computer colour matching for textile applications on July 9-10, 2015. The course will be taught by Dr. Narendra Gangakhedkar and Wool Research Association scientists and will provide training on the Wool Research Association's latest internet-based colour matching system. Attendees will learn colour theory, matching techniques, database development, and methods for obtaining accurate colour matches and controlling colour processes. The course is intended for textile chemists, colourists, managers, and others involved in colour quality management.

ADVANCED COURSE IN MATCH PREDICTION
(July 9-10, 2015)

Computer Colour Matching is an established tool. If anyone wants to learn how to get the
Colour “Right First Time” with colour matching system, he/she need to attend the advance course
for understanding the science and technology of colour. Here is an opportunity for all to revise colour
theory as well as knowledge and skill of colour matching.
Wool Research Association (WRA) has developed the latest internet based colour matching system
for textile applications. It is introduced in small, medium and large Mills. It is a low cost affordable
solution for small and medium textile processors. They have to buy low cost affordable instrument
and connect their in-house PC to WRA website for getting the instant match. WRA has developed a
huge database of different substrates – processes – dyes combination. WRA is organizing this
program for training colourists and Managers in Dyeing Departments. WRA Colour experts and
Scientists will guide you for use of this system with practical demonstration.
Dr Narendra S Gangakhedkar who is having many years of experience in computer colour
matching will explain to you how to control your colouration processes and stop losses. With his vast
practical experience in industrial colour technology, you will learn how to select colourant in
formulation, specify colour tolerances for pass/fail of incoming raw materials such as dyes and
pigments, control finished colour products for meeting specifications of end users and inspect
manufacturing process for avoiding rejections. He is the author of two books on Colour Science -
namely "Understanding Computer Colour Matching" and “Understanding Science and
Technology of Colour ". These books were reviewed in the International Journal “Colour Research
and Application” and were highly appreciated for the contents and his sharing of industrial
experience.
Today, Indian companies have been exporting goods to US and European retailers who are
specifying stringent numerical colour tolerances and companies are finding it difficult to meet their
digital specifications for getting valuable repeat orders.
As colour quality is non-negotiable., you have to get the given colour right first time.
You don't just do it right, you have to do it better.
You have to lower the cost of colouration.
You have to invest in colour instrumentation and process control.
You have to educate and train your colourist for new colour technologies.
One need to attend this advance course for better understanding of computer colour matching
for textile applications.
Course covers how to develop a unique database for obtaining an “Instant Colour Match” and how to
use WRA COLOURMATCH. In special session on “Colour Clinic”, Dr Gangakhedkar and WRA
Colour Scientists will share their practical experience and offer solutions to your colour problems.

2. WHY THIS PROGRAM?
It is a continuous education program to revise/update you in colour science and technology. It is
a must for any colour expert / modern dyer / dyeing manager and anyone who is involved in
colour management. It is unique program offering the latest internet based digital colour match
and colour control.
If you are having CCM system, then this program will help you to increase effective use of your
system. You can also become user of WRA COLOURMATCH.
