Here's a book that will save you time and money as you master the digital halftone process, from scanning images to tweaking them on your Mac to image setting them. You'll learn about optical character recognition software, gamma control, sharpening, moires, PostScript halftones, Photo CD, and image-manipulating applications like Photoshop and PhotoStyler.Many people who are proficient on their PCs and Macs don't have a clue about scanners. Others have tried to use scanners, or incorporate scans into their documents, but with less-than-satisfactory results. Now there's a book that explains - in clear, simple language and with profuse illustration - what people need to know about scanners, and about the related subject of halftones as well. Written by desktop publishing gurus David Blatner and Stephen Roth, Real World Scanning and Halftones covers topics from image acquisition through high-quality output. Not only does the book explain in step-by-step detail which buttons to push to get high-quality images, it provides the conceptual underpinnings so users can become proficient on their own. While the book is general in nature, it also refers to the most popular programs and scanners by example, providing users with the detailed information they want while maintaining the conceptual overview they need. One of the central topics of Real World Scanning and Halftones is digital halftoning - explaining how color and gray-scale images are reproduced on the printed page using laser printers and imagesetters. This explanation has never been adequately provided in one place in the depth users need to understand the topic. In addition, the book demystifies the world of OCR, or optical character recognition.
