Scan workshop outline May08.doc handout Ursula Hoffmann, May 3, 2008
Scanning Text and Graphics
1. Welcome to the new Faculty Lab
2. Copier vs. scanner: both photograph an image
3. Why scan to get digitized material? This takes time.
· For yourself: Perhaps a printed copy of an article no longer on your computer. Perhaps your slides or old photos for archiving purposes.
· For e-mail to friends or colleagues.
· For your students, to make material available to them: Options: Put printed material on reserve in the library, OR put a lecture about this material online, OR scan your material and put it on student CDs or put it BB – making sure that you observe all rules on copyright and fair use (see http://www.lehman.edu/faculty/hoffmann/itc/techteach/index.html > Copyright.)
4. What might you want to scan?
· Scanning printed text as image– see http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/scan.html and http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/scantext.html
· Scanning printed text for purposes of OCR (i.e. editable text)
· Scanning printed graphics or transparencies – see http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/scanimage.html
5. Material suitable for putting online or e-mail – quality and image
size and file size
Any graphic, whether printed or transparent. But be careful about printed text, especially a book or magazine. Also, individual pages must be clean and have no staples, paperclips, curled or bent edges. Use a copy shop to make good copies for you if needed.
6. Important details for e-mail or online digitized materials:
· small file sizes, easily legible – see examples http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/text_samples.html
· format as Acrobat .pdf for its advantages: search, zoom, scroll
· recommended format for images as it can be compressed to a smaller file size: .jpg
· Alternately, there is OCR for editable text but it is much more work.
7. Important details for graphics:
· You need to know your destination: print, e-mail, web for resolution and file size
· Scanning slides
o Examples if time and internet access: see links at end of http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/scan.html
o If you scan slides to create a PowerPoint presentation to put online, check with John. The college has a licensed version of Impatica which will compress the presentation for online use.
8. Hardware and Software. Scanners with included software are inexpensive, as is additional quality software so you may want to work at home--see below and http://www.lehman.edu/faculty/hoffmann/itc/techteach/scan/scanners.html
Otherwise, work in
the Faculty Lab.
9. Demonstration of scanning
Scanners in the new Faculty Lab:
There are three scanners in the third row by the window, from left to right, window to aisle:
1) HP Scanjet 8390, document flatbed scanner with automatic document feeder and transparent material adapter. This will scan any printed material. If you want to scan transparencies, such as slides or film strips, you need an ITC officer to get you started, and then contact the officer when you are finished.
2) Epson Expression 10000XL color flatbed scanner. This will scan printed material including posters or maps up to 12.2” x 17.2” in size, in very high resolution for professional quality.
3) HP Scanjet N7710 Document sheet-feed scanner. This lets you scan a business card or 1-50 pages. It is very fast.
