Open Access Graduate Research Paper
Process color photography has been continually developing for many years. In fact, color printing techniques are still benefiting, through additional sophisticated requirements, and from a discovery made about 300 years ago. At that time Sir Isaac Newton, British scientist, mathematician • and philosopher, placed a glass prism in the path of a narrow beam of sunlight entering his room through a pinhole in an opaque window shade. He determined that ordinary white light is a mixture of colored lights.
Unfortunately, in practice, ideal pigments for three-color inks do not exist and this impasse greatly complicates the job for the photo-processor. To improve the accuracy and speed of color reproduction, one of the newest methods of color correction being employed today is the electronic scanner. Electronic color scanning is accepted today as a rapid method of producing very high quality color separations.
This research paper attempts to uncover some of the "mystery" associated with these electronic marvels in a systematic presentation. Conventional techniques in color separation theory are described first, . including types of copy and color dimensions involved in separation work. With a practical understanding of traditional (conventional) color separation techniques clearly defined, the reader is introduced to early attempts at developing working scanners, some popular present day scanners and finally an outlook into the future growth and potential use of color scanners in the graphic communications industry throughout the world.
