The quality evaluation of multiform copies falls into the same category as color, odor, and taste measurements since the senses and psychological influences of the observer are involved. Nevertheless, manufacturers and users of business forms have felt the need for instrumental methods and quantitative values in measuring the properties of copies. In this series of papers, several instruments and measuring concepts are presented. Many of the problems related to this type of product evaluation are discussed, particularly the need for precise specimen preparation and careful reproducibility of results. While only one paper relates to electrostatic copying, the kinship between the older impressioned copy and its younger cousin is unmistakable. A final paper offers a description of the mechanics of ink transfer from carbon paper or ribbon during impact. The theories proposed in this paper represent a significant advance in current concepts and should prove to be very useful to the technology of business forms. Considerable effort has gone into the development of business copy products, and, while their influence on our lives frequently is not appreciated simply because of their ubiquity, we literally could not live our modern lives without them. Every bill we receive, every item we buy, sell, or ship has a document related to it (prepared, at least, in triplicate) and is a product of the business forms industry.
