PRINT QUALITY VERY GOOD
COLOUR PRINT QUALITY vEry good
 The Canon imagePROGRAF iPF820 produced a typical gamut for an inkjet colour
printer. BLI’s test instruments showed that colour remained consistent over the
course of the test and no noticeable changes were detected in a visual observa-
tion of a group of images printed at the end of the test period compared to the
same group printed at the start of the test.
 At the print driver’s default setting, colour charts, architectural plans and maps
printed on plain paper displayed very good image quality. Fine lines and curves
printed distinctly and colours were bright and of good density.
 Colour photographs printed on Canon’s Heavy Weight Satin Photo paper exhib-
ited very good image quality at default settings, displaying high contrast and
sharpness, with natural-looking colours and skin tones.
BLACK PRINT QUALITY vEry good
 Black-only architectural documents were rated Very Good, with consistent line
widths, fully formed circles and no stairstepping of diagonal lines.
 In composite black mode, halftones were rated Very Good, with smooth fills and
little to no evidence of composite colour mixing as is often seen in rival units.
 Black print quality on plain paper was rated Very Good overall. Characters
appeared dark and fully formed, with some ink spray visible, which had an impact
on the clarity of the finest white lines on black background test elements. Circles
were cleanly formed. Diagonal lines were straight, with no stair-stepping evident.
Grayscale was visible over a normal range, from 1% to 93%.

 The imagePROGRAF iPF820 wakes from power-save mode quickly. After a week-
end of non-use, the printer awoke after 34 seconds and began to print a D-size
document 50 seconds after the print was initiated from the driver.
 To assess colour print productivity, one 12-page Arch D-size DWF document
was used. This document was printed using the Canon imagePROGRAF iPF820
driver set for plain paper/colour, using three different quality settings—Draft,
Default and Highest Quality. In Draft mode, the 12 pages printed in 7 minutes
and 26 seconds, which translates to 96.8 pages per hour (pph). In Default mode,
the document printed in 12 minutes and 42 seconds, which translates to 56.7
pph, and in Highest Quality mode, the document printed in 24 minutes and 48
