Document imaging is a new discipline in applied computer science. It is building bridges between computer graphics, the world of prepress and press, and the areas of color vision and color reproduction. The focus of this book is of special relevance to people learning how to utilize and integrate such available technology as digital printing or short run color, how to make us of CIM techniques for print products, and how to evaluate related technologies that will become relevant in the next few years. This book is the first to give a comprehensive overview of document imaging, the areas involved, and how they relate. For readers with a background in computer graphics it gives insight into all problems related to putting information in print, a field only very thinly covered in textbooks on coputer graphics. 1 Preface.- 2 Introduction.- 2.1 A Simple Reference Model for Document Imaging.- 2.2 Topics Covered.- 3 Color Phenomena in Display and Printing.- 3.1 Introduction.- 3.2 The Human Eye.- 3.2.1 Retina: Rods for Brightness and Cones for Chromaticity.- 3.3 Eye Response Functions.- 3.4 Illuminants (Daylight, A, B, C, D50, D65) and White Point.- 3.5 Metamere Colors.- 3.6 Tristimulus vs. Opponent Color Theory.- 3.7 Model of Vision for Colored Objects.- 3.8 Equally Distant Color Systems.- 3.9 Color in Printing: RGB, CMY(K), CIE L*a*b*, and Separations.- 3.10 Halftoning.- 3.11 Simple Model for Halftoning Screens.- 3.12 Clustered Dot Halftoning.- 3.13 Dot Shapes.- 3.14 Overprinting of Multiple Separations.- 3.15 Rational vs. Irrational Screens.- 3.16 FM screens.- 3.17 AM, FM, and Dot Gain.- 3.18 A Simple Printing Model: The Neugebauer Equations.- 3.19 Printing Processes on an Offset Press.- 3.20 Press Measurement.- 4 Fully Digital Workflow for CIM for Print.- 4.1 Creative Systems.- 4.2 Layout Tools.- 4.3 Imposition Tools.- 4.4 OPI Servers.- 4.5 RIPs.- 4.6 Trapping.- 4.7 Image Setters.- 4.8 Plate Copiers.- 4.9 Presses.- 4.10 Finishing Equipment.- 5 Formats.- 5.1 PostScript.- 5.2 Acrobat and Portable Document Format.- 5.3 Tagged Image File Format (TIFF).- 5.4 CGM.- 5.5 Image Interchange Facility (IPI-IIF).- 5.6 Prepress Interchange Formats.- 5.7 PhotoCD.- 5.8 Document Related Standards.- 6 Problem Areas.- 6.1 Color.- 6.2 Fonts.- 6.3 Resource Requirements.- 7 The Integration Problem.- 7.1 Integration of different Formats.- 7.2 Conversion to a single Format.- 7.3 Integration without Conversion.- 8 Information Interchange for the Production.- 8.1 Media Use for Information Interchange.- 8.2 Interchange of Editable Objects.- 8.3 Advertisement Transmission from Prepress to Newspapers.- 8.4 The CIP3 Print Production Format (PPF).- 9 Outlook: From Printing to Cross Media Publishing.- Bibliography and References.
