PREFACE he industrial application of color technology has reached a major crossroad. In the past decade great progress has been made by scientists i n industry i n applying the objective techniques of color science. Major benefits have been realized by using color measurement and colorant formulation theory, replacing the trial, and error methods based on visual observation alone. The practicability of this approach has been proved, but problems still remain. Accordingly, a special symposium was arranged to give a concise, "state of the art" summary of the application of this specialized science to industrial processing. This volume is a collection of those papers. The first chapters discuss the basic concepts of the science of colorimetry, color measurement, color difference metrics, color appearance, and the importance of the engineering aspects of the materials involved. This introductory material is necessary for an audience which may not have been exposed to the various specialized aspects of the sciences involved. Only a few universities offer courses in the science and technology of color because the interdisciplinary nature of color science does not fit readily into their rigid curriculum. Hence, the topics presented i n the first six papers were selected to provide a guide to those aspects of the science which are of the greatest practical importance in industrial processing. The practicing specialist may chafe at certain omissions and may criticize the elementary level, but it is hoped that the non-specialist w i l l garner sufficient insight and be exposed to enough of the most important literature references to pursue the subject further.

Included in this first group of papers is the presentation on the perception of color. This fascinatingly beautiful lecture is reproduced here with illustrations which, to as great an extent as is possible i n two dimension, serve to emphasize the complexity of the human visual process. It is a distinct privilege to be able to present this classical lecture i n printed form. It is hoped that it w i l l be a constant reminder of the limitations of a purely technical approach to a psychophysiological phenomenon. The second part of the program begins with a paper on colorant formulation theory. This is followed by papers presented by practicing color scientists i n various representative industries. It was impossible to include papers from all of the colorant-using industries, but a sufficient number are included so that the reader can form an impression about the ix

extent to which the tools and techniques of color science have been applied. It is an honor to have D r . Wallace Brode, former president of both the American Chemical Society and of the Optical Society of America, provide the introductory lecture on the interdisciplinary character of color science. It is largely through his efforts when he was president that the A C S has become a member body of the Inter-Society Color Council. R U T H M. JOHNSTON
