An excellent question! Although this topic has been covered by a number of postings over the past few years, I have not seen a formal list published. To get the ball rolling, allow me to offer some suggestions:
1. Always scan directly into PDF, rather than into an image format such as JPEG, GIF, or TIFF. 2. Always scan text and schematic diagrams as 1-bit line art. 3. Always scan at 300 dpi resolution. 4. Always scan pages erect at 11" high (do not rotate for viewing- the Adobe Reader can do that). 5. Never scan long pages in segments; let a commercial graphics house scan it as one page. 6. Scan pink-and-gray PCB images in 8-bit gray scale rather than in full color. 7. Scan photos in gray scale only if important detail must be preserved; otherwise, use line art. 8. Don't scan irrelevant pages, such as pages for notes, parts ordering, customer feedback, etc. 9. Adjust scan margins as necessary to leave room for binder hole punching. 10. Adjust contrast and gamma as necessary to compensate for faded text or colored originals. I prefer the full Adobe Acrobat Professional 4.0 for the scanning phase, and Adobe Acrobat Professional 7.0 for collating, editing, and reducing file size. I use a MicroTek Scanmaker 9800XL large-format flatbed scanner that can handle up to 11 by 17 inch originals. Although I am permitted to use a Xerox self-feeding scanner at work, I have found its decisions about contrast and saturation to be below my expectations, so I often prefer to handle the scanning myself- especially if the product will be posted for future downloading by discriminating Hams! 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kris Kirby Sent: Tuesday, March 09, 2010 4:38 PM To: [email protected] Subject: [Repeater-Builder] Writing Guidelines I see the guidelines for writing; what are the guidelines for scanning documents? -- Kris Kirby, KE4AHR Disinformation Analyst
