Enhanced Calibration - Canon C850 Practical Manual

Enhanced Calibration

This type of calibration is recommended if you want to correct the shades and tones of colors as precisely as possible,
even if it takes more time and effort� This is also suitable if the environment (temperature and humidity) in which the
machine is installed does not satisfy the recommended range for some reason� This type of calibration uses specific
types of paper, which correspond to the types of paper you want to print on, so that more precise corrections can be
achieved� The paper is categorized in three groups, group A, B, and C, for the purpose of more precise calibration� See
the list in "Types of Paper You Can Use for Calibration" at the end of this document� Find out in which group the paper
you want to print on is categorized, and then select the corresponding type of paper you can use for calibration� To
keep making corrections precisely, calibrate the machine for the paper you are printing on whenever you print on
paper of a different group� For example, if you print on plain paper, which is listed in group A, in the morning, and print
on Heavy 5, which is listed in group B, in the afternoon, calibrate the machine for paper in group A (p� 6) before starting
printing jobs in the morning and calibrate the machine for paper in group B (p� 7) before starting printing jobs in the
afternoon�
