Large Format Scanning

content last updated 2-18-2020


The Canon L24ei scanner is located in the Green Lab (Cowell G25) which is on the ground floor of Cowell Hall.


Any student, instructor, or staffer affiliated with the Department of Art + Architecture may take their large-format originals to the Green Lab (Cowell G25) during scheduled open study hours and the Lab Assistant on duty will scan their originals upon request.



Originals must be:

  • larger than 11 inches x 17 inches1 and no wider than 24 inches2 on the shortest side
  • no thinner than 0.07 mm or 0.003 inches or 3 mil (roughly 25% thinner than a single sheet of 20 lb copy paper)
  • no thicker than 0.5 mm or 0.02 inches or 20 mil (roughly the thickness of a stack of 6 sheets of 20 lb copy paper)
  • opaque or translucent material


  • not film or other backlit material
  • not cling or adhesive material
  • flexible, not rigid
  • flat and of uniform thickness
  • not prone to smudging (sealed with fixative spray, if necessary)
  • free of staples, paper clips, Post-it notes, loose tape, and other attachments

To scan originals that are 11" x 17" or smaller, use the self-serve flatbed scanners in the Orange and Green Labs during scheduled open study hours or the network of pay-per-use Pharos multifunction printers or "MFPs" across the USF campus.

2 Originals larger than 24" on the shortest side can be scanned with another device elsewhere on campus by special arrangement with the Director of A+A Technology.


There are many measurements for the overall "heft" of a piece of paper. These measurements fall under two categories: weight (or density) and thickness (or caliper).

Weight has no correlation to thickness. Weight is useful for comparing the overall heft of different types of paper. Likewise, thickness has no correlation to weight because paper can come in such a huge array of compositions. (Imagine two 1' x 1' x 1' cubes: one made of styrofoam and one made of steel. They would have the same thickness, but very different weights.)

Look closely at your paper's packaging for one or more of these measurements:

Paper Weight (or Density)

  • Pounds ... abbreviated lb ... also known as the "Basis Weight" ... the weight of 500 sheets of your paper at its uncut size, i.e. before being cut down to Letter size or Legal size, for example
  • Grams per square meter ... abbreviated g/m2 or gsm

Paper Thickness (or Caliper)

  • Inches ... abbreviated " or in
  • Millimeters ... abbreviated mm
  • Mils ... abbreviated mil (not to be confused with millimeters) ... one mil equals 0.001 inches
  • Points ... sometimes used interchangeably with mils ... one point also equals 0.001 inches

A note about conversion: You cannot accurately convert between units of paper weight and paper thickness. You also cannot accurately convert one unit of paper weight to another (lb to g/m2 or vice versa). Any conversion charts you find online will only offer estimates. However, you can accurately convert one unit of paper thickness to another.
