- Calibration: Make sure that you use a color
management system and calibrate
your scanner on a regular basis in order to get consistent and reliable results.
- Environment: The environment refers to the humidity, temperature,
and air quality in the space occupied by the scanner. It should be a clean,
smoke-free, and dust-free area. If carpeting is used in the area, you should
incorporate static control. The temperature should be about 70 degrees F with
about 50 percent humidity.
Make sure you keep the glass on the scanning bed as clean as possible. Dust,
scratches, and fingerprints will affect the final quality of the scan.
- Vector Art: When an image is scanned, it is saved as a bitmap image.
The only way to get a vector image from the bitmap image is to trace the image
with the pen or use the autotrace option found in Photoshop®, and save
the path. There is also special tracing software that automatically converts
the bitmap images into vector images. The traced path
can then be exported to Illustrator® or FreeHand®. Vector art is created
with mathematics instead of bitmaps and is sometimes called "object art"
because all the shapes and colors are created by the outlines of the objects.
The files sizes are much smaller than bitmaps.
- Batch Scanning: Some scanners come with an ADF (Automated Document
Feeder). The ADF allows multiple documents to be automatically fed, scanned,
and saved.
- Legal or Infringement: When working with digitized images, make sure
you secure all reproduction rights before using them. You can't just scan
a photograph or image out of a book, magazine, or elswhere. There are copyright
laws that are being violated if you do. Authors, publishers, and photographers
copyright their work, so check carefully before using or infringing.
There are special copyright-free/royalty free images available from several sources. Click the link to view
a listing of some of them.
