Printer notes:

For best results, we recommend printing the Jewelbox Image and StarGauge on an ink-jet printer, using the highest resolution available and good quality paper designed for use on an ink-jet printer. Resolutions of 720 dpi should be acceptable, and available on most ink-jet printers. Resolutions up to 1440 are preferred if available, since students will be able to distinguish fine detail more easily.

Color laser printers can also be used, but may not produce an image of as good quality as a good ink jet printer.

Thermal die-sub printers will also produce excellent quality prints for use in the Jewelbox activity, and may be available in copy shops such as Alphagraphics or Kinkos.
