Testing was completed by faculty, staff, and students in the Graphic Communication Department
at Cal Poly State University (www.calpoly.edu) under the supervision of Professor Michael Blum.
The Department is one of the leading institutions of its kind in the nation, and offers a BS
degree in Graphic Communication with concentrations in Printing and Imaging Management,
Design Reproduction Technology, Electronic Publishing and Imaging, Graphics for Packaging, and
Individual Study. The Department also houses the Graphic Communication Institute at Cal Poly
(GrCI). The GrCI provides services to industry including research, testing, product evaluations,
consulting, seminars, workshops, and conferences (www.grci.calpoly.edu). The documents tested
ranged from previously printed faculty and student work, to new documents created for this
project. The page lengths of the documents tested ranged from 1 page to 735 pages per document.
As part of the test suite, paper handling capabilities of the printer were utilized from the various
applications, including simplex and duplex, collated and non-collated, portrait and landscape, and a
variety of paper sizes including Letter, Tabloid, 12” x 18”, and 12.25” x 40” banner stock.
A range of substrates was tested on the 7450 to note both the ability to feed properly and the color
quality obtainable on each. During the testing, the following substrates were used:
Futura Laser 100# Gloss Text
Futura Laser 100# Dull Text
Futura Laser 80# Gloss Cover
Future Laser 80# Dull Cover
Kromekote 12 pt Cover
Technisource 80# Gloss Cover
Technisource 80# Matte Cover
Technisource 28# Copy Writing
Technisource 80# Copy Cover
Technisource 10 pt Super Gloss Cover
A database was designed for this project to track the testing on the 7450 printer. Each job printed
during the course of testing was entered into the database including the application used, substrate
size and type, coverage, document type, page count, run length, print quality, and results. A typical
entry screen for this database is shown below.
