This book is printed in multi-color on
art paper. It is the most illustrative work with figures and
practical examples of computer outputs of color measurement
and computer color matching. There are 84 color illustrations
and 21 tables. It is a comprehensive book covering the basics
of color science and computer match prediction systems for
textiles, paints, plastics and inks.

Personally, I wanted to say that I like
the look and feel of your book. It is a handy little reference
that doesn't shy away from more technical issues. Thank you
for sharing the book with me. I am pleased a wider audience
will learn about it in the journal.

In the preface to his book, Dr.Gangakhedkar
states that his purpose is to provide comprehensive information
on various aspects of modern color science and technology
and to share his practical industrial research experience.
The appearance of the book
is that of a pocket handbook of information concisely listed.
A person attending one
of Dr. Gangakhedkar's courses would probably find this book
a good companion volume.
Since the source of most of the material in the book was lectures
or presentation, the book is written mainly in an abbreviated
The book consists of ten chapters: 1) a brief introduction
to color and color science; 2) color difference equations
and visual color assessment; 3) quality control of color including
whiteness, yellowness and other color indices; 4) metamerism
and the CIE metamerism index; 5) color instrumentation; 6-10)
color matching calculation.
The book ends with 75 references, a list of additional readings,
and a bibliography of the author's publications.
Let me say a little more about some specific chapters. Chapter
5 on instrumentation describes the various criteria to be
used in selecting an instrument and compares a number of instruments.
Instrument comparisons are difficult because they become out-of-date
almost as quickly as you can get them published. However,
at this date, the instruments described are those currently
being used in industry, and the chapter gives the reader a
feel for what is available, as well as some of the functions
available on the instruments.
Chapter 6 describes how Kubelka-Munk theory is used for color
matching textiles. Included is a section on the theory versus
the practical limitations of the Kubelka-Munk theory. Some
of the material presented in this chapter is applicable to
color matching other materials so it should not be skipped
if the reader is not interested in textiles. The author describes
the factors needed to select the optimum dye combinations
for recipe preparation. There is also a section on the successes
and failures of computer color formulation in textiles.
Chapter 7 is about using two-constant Kubelka-Munk theory
for formulating colors in
paint, plastics and ink. It also includes sections on determining
scattering, hiding power and tinting strength based on the
Kubelka-Munk equations. The author discusses some of the factors
affecting colorant formulation predictions and color measurement.
He also includes a section on formulating the color of wet
paint using a non-contact spectrophotometer.
In chapter 8, the author shares his experience on various
aspects of color science and technology based on his notes,
observations, presentations at seminars and his previously
unpublished research findings. Sections in this chapter include
factors affecting visual color difference evaluations, preparing
good paint samples for color evaluation, raw material control
and tips for the optimal performance of spectrophotometers
Chapters 9 and 10 are complete articles or extracts on specific
topics. Chapter 9 on the development of color software consists
of a papers presented by the author on Computer color matching,
a paper on the factors affecting the accuracy of predicting
correct color formulas and an excerpt from one of his books
on pigment loading. The
last chapter, 10, is the abstract of the talk "Computer
Color Matching: The Indian Experience" presented at the
AIC, 25th Anniversary Meeting in 1992.

The book is so well printed that after
receiving it, I just started reading it and found it very
interesting. But I realized it that I have to read at home
I have completed the reading in detail. I am quiet impressed
by it. Some of my observations are:
Overall, I am verymuch impressed.
- Preface shows exhaustive hard work of the author in gaining
the knowledge. He deserves it.
- Excellent illustrations and diagrams.
- Recommendation for visual examinations of color matching
especially in the production the correct light source equipment
should be used.
- Many new terms are well defined.
- Chapter on Modern color instruments is very useful.
- Chapter VIII on Author's Practical Experience is very

It is a very good book and very useful. I'll use it to understand
some important issues about Color.

Really your book is very well written.
This morning, I have sent to our office in china some illustrations
from the book by fax. They are impressed and there is demand
for the same. We will ship your books to them.

I have seen the book and a quick scan through
it indicates that it has good coverage of the topics likely
to be of interest to an industrial color technologist.

Computer Color Matching
Thank you very much for a copy of your
new book "Understanding Computer Color Matching."
My sincerest congratulations to you on the completion of this
comprehensive work. I am sure that many people will find this
a useful primer and reference book. However, I appreciated
your very practical observations such as saturation in measurement
technique but the need for further development of software
technology in color matching.
I cannot help but compare your book to that of Rolf Kuehni.
I must say that yours seems to be both more practical in its
approach and also more useful as a reference. Again, my congratulations
President, Datacolor International
It was with great pleasure that we received
your excellent book "Understanding Computer Colour Matching"
and we wish to congratulate you on this superb publication.
Dr. Rohner and I had quite a close look at your book and we
found that the content really reflects the knowledge someone
should have who is dealing with industrial color matching.
We think that you did a particularly good job in explaining
a complex content in very understandable words and in particular
we appreciate the many samples which are supporting the theory.
These samples will also help a lot of readers to find guidelines
for their own work. No doubt that you can look back on many
years of successful practical experience with color measurement
and colour matching.
Managing Director, Datacolour International
In the view of the paucity of literature
in the field, a new book on Computer Color Matching (CCM)
will be greeted with great interest. This book, written with
obvious sincerity and deep feeling by an experienced practitioner,
is not only an exposition of CCM but also a plea for more
widespread and intelligent use of the Computer in Computer
Formulation and Control. In the latter capacity, it succeeds
very well. The book is discursive and informal, and that's
what gives it its appeal.
The layout is attractive, with boxed-in quotations, aphorisms,
or illustrations on almost every page.
The chapters, based on extensive experience of the author
contain very cogent points on the use of CCM that will be
of great interest to every practitioner.
The chapter titled "K-M Equations for Solving Textile
Colour Matching Problems"
presents the usual matrix algorithm for single constant K-M
theory. The presentation is unusual in that a completely worked
out numerical example is given; this can be used to check
your programming, if you are writing your own program.
If you would like to spend some time with your colleague from
India while he takes you by arms and talks, in his own fashion,
about how he uses CCM and how it can be improved, you will
enjoy this book.
