This highly useful, detailed guide helps desktop-publishing and other design professionals produce the best possible scans and halftones from their images. The first section focuses on scanning, first featuring explanations of such terms as spi (samples per inch), bit depth, optical and interpolated resolution, and dynamic range. The authors even advise you on buying and cleaning scanners. Next they detail the elements of good scans and how to fix less-than-perfect ones, helping you figure out what sort of file formats and resolutions to use in your work, how to do tonal and color corrections, and how to sharpen and compress images. Finally, the discussion turns to Web and printer output and to OCR technology and PhotoCD images.

The section on halftones teaches you how to produce decent halftone images, first by explaining how halftones work and then by explaining such issues as frequency, gray levels, spot variation, spot gain, spot shapes, and the role of printers and software in creating halftones. There's also a discussion of stochastic screening and how to create blends and reduce moiré and other patterns. The last chapters here help you fine-tune your halftone settings and learn a bit about PostScript operators for halftones and scanning.

The third and last section focuses on using image applications to work with scans, tonal and color corrections, and halftones. This discussion includes Adobe Photoshop, Micrografx Picture Publisher, Corel Photo-Paint, Ulead PhotoImpact, Equilibrium's DeBabelizer, Adobe Illustrator, Macromedia FreeHand, CorelDRAW, Adobe PageMaker, and QuarkXPress. The authors also look at a few scanning applications and offer tips on using them.

Throughout the book the authors provide plenty of images and screen shots to illustrate their points, and a full-color section helps bring some of these examples to life. There's lots of technical discussion, but since each chapter builds on the previous ones and the basic terminology is put forth clearly, you can leave off wherever you wish and still have a lot of new knowledge to apply to your scans and halftones. --Kathleen Caster

Author notes: 3rd Edition Entirely Revised
As one of the authors of the third edition of the book (2004), let me tell you that the third edition (2004) has been entirely revised, redesigned, and overhauled. Keep that in mind as you read reviews below of the 2nd (1998) and 1st editions (1993).

In the latest edition, we've restructured the book around the scanning and digitzing workflow: starting with scanners and digital cameras; moving through correction; then into output onto ink jet, film, screen, and (extensively) offset press as halftones.

I'd call this a "Try it."
Frequently, I find that I have to buy books that are overly technical for my purposes in order to get all the info I want. This book suits me, (though it may not suit the needs of a graphics profession). There are no buyer's guides to specific models of scanners here. However, there is a lot of detail about how scanners, scanning software and graphics programs work. The authors provide such arcana as the formula for determining what size a scanned image will be (depending on the options you pick) and goodies like this. There is info on file formats, compression, how to choose resolution and what influences the outcome of scans and how to correct the result. There is also a lot of information most applicable to professional print work, for which I have no particular use, except that info of this type helps to fill out my picture of how digital imaging works. If you want suggestions for scanning projects to do with your kids, look elsewhere, but if you're interested in the theory of scanners I would recommend this book. I'll also mention that, in my view, the writing is clear and well-organized and if I occasionally must pause to consider it's only because the material requires a little thought. This is not rocket science, but neither is it Sponge Bob and the authors treat it accordingly.

Great title...
I've learned some thngs from this book, however like one other reviewer stated, just when you thought it was going to get to the good stuff, some stupid flip remark would be made and the chapter or discussiong would end. Very difficult reading. Too much about prepress. Not enough about photoshop, scanning and color management. Reads like childish manerishums. Author's have very immature writing styles.
