George, I do a lot of manual scanning, and I have evolved a "standard" of sorts that I personally follow, and recommend to others. This is a personal preference, and should not be considered a requirement for any submission to be published on the Repeater-Builder site. Herewith are my personal preferences:
1. Always scan directly into PDF as a document, never into any image format such as JPEG, JIF, or TIFF. 2. Always scan at 300 DPI resolution, to maximize laser printing clarity without making the files too large. 3. Always scan schematics and text as 1-bit (line) drawings, with the white and black points set for optimum contrast and density. 4. Scan photographs and color separations as 8-bit (gray scale) drawings, if necessary to preserve detail. If not, scan as a line drawing. 5. Never make segmented scans of long pages. Take those pages to a graphics shop for full-page scans into PDF. 6. Always scan pages as they are bound, so that all scans are 11 inches high regardless of orientation or length. (PDFs are automatically rotated for printing) 7. Always add page numbers, using the Adobe Text Tool, when they are missing. 8. Always add a note to indicate if a following page is blank. 9. Don't scan irrelevant pages, such as how to order spare parts from depots that haven't existed for years. 10. Never scan and submit for publication any manual that is still in print, unless you want to be sued for copyright infringement. I prefer to use Adobe Acrobat 4.0 Professional for most scanning, and I then perform optimization in Adobe Acrobat 7.0 Professional. The result is a document that is not only versatile, but is much smaller than any image format. Long pages can be printed on a document (roll) printer at most commercial graphics shops, along with many Kinko's shops. The real beauty of PDF is that a portion of any long page can be selected using the Adobe Reader "Snapshot" tool, and then printed on standard 8.5 by 11 inch paper. For example, you might want to print just the final stage in a power amplifier schematic diagram that was originally almost three feet long. Just use the snapshot tool to select that portion, and now you have exactly what you want. You can also save that selection as a separate PDF to send to someone in an e-mail. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of George Henry Sent: Thursday, October 23, 2008 2:33 PM To: repeater-builder@yahoogroups.com Subject: [Repeater-Builder] Guideline for scanning manuals? What are the guidelines for scanning manuals for the RB site? I want to scan & upload the manuals for the MSR 2000, but they are HUGE... Tried doing the VHF manual today at 200 dpi, and even choosing Acrobat's "reduced file size" option, it came out to 101 MB!!! (the UHF and Audio/Control manuals are coming any day) I presume they should be scanned in B&W, not greyscale or color (unless needed for images/PC board layouts...), but at what resolution? And Kevin or Mike, can you send me the ftp instructions again? I seem to have lost them.......... George, KA3HSW / WQGJ413
