Available models differ depending on your region and product release dates�

Recommended Types of Calibration

The density and tone of colors may change as you print large volumes of pages� Even if you are printing the same image, slight variations in the shades of colors may become apparent� This is characteristic to this machine� You need to calibrate the colors periodically to compensate for the difference in colors� The following two types of calibration can be done periodically� Refer to the following and select the type of calibration that meets your needs�

Simple Calibration Enhanced Calibration

If you want to calibrate the colors quickly and

easily*

If you want to calibrate the colors as precisely as possible even if it takes time and effort

If the environment of the location in which you have installed the machine is outside the recommended range*

*1 You can select this type of calibration only if the environment in which the machine is installed is within the recommended range*2�

*2 For information on the environment (temperature and humidity) for installing the machine and storing paper, see the

Installation and Operating Environment Guidelines or the Specialty Media Handling Guide�

Recommended Types of Calibration

Other Types of Calibration You Can Do When You Notice Variations in the

Shades and Tones of Colors

The following calibrations can be made in addition to Simple Calibration and Enhanced Calibration� Calibrate the machine only if you notice irregularities in the colors� (You do not need to calibrate the machine on a regular schedule�) Make sure to do automatic gradation calibration prior to doing either one of the following calibrations� If you are using the imagePRESS Server and a spectrophotometer, such as an X-Rite i1 Pro, you can make more precise corrections by doing both Shading Correction and Automatic Color Tone Correction� In this case, do these corrections in the following order: Automatic Gradation Calibration → Shading Correction → Automatic Color Tone Correction�

Shading Correction

Do this if the color densities become uneven�

Automatic Color Tone Correction

Do this if you notice differences in the color tones�

imagePRESS C850/C750/C650/C65

Simple Calibration

If you want to correct the printed colors quickly and easily, this type of calibration is recommended� Do steps 1 to 3 in "Calibration After the Machine Is in Operation" once a day� (p� 37) This is, however, done on the premise that the environment (temperature and humidity) in which the machine is installed satisfies the recommended range� If the environment does not satisfy this range, do "Enhanced Calibration�" (p� 5)

Prior to Starting Simple Calibration

See "Adjustment for Image Quality and Finishing (Calibration)" > "Automatic Gradation Adjustment" > "Changing Adjustment Level" in the User's Guide, and set [Adjustment Level] for automatic gradation adjustment to 'Same for All Paper Types'�

imagePRESS C850/C750/C650/C65

Recommended Types of Calibration

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�

Prior to Starting Enhanced Calibration

See "Adjustment for Image Quality and Finish (Calibration)" > "Automatic Gradation Adjustment" > "Changing Adjustment Level" in the User's Guide, and set [Adjustment Level] for automatic gradation adjustment to 'By Paper Type Group'� If you are not sure of the name of the paper to use for calibration, contact your local authorized Canon dealer�

NOTE

The density and tone of colors may change as you print large volumes of the same pages, even if you are printing the same image, slight variations in the shades of colors may become apparent� This is characteristic to this machine� You need to calibrate the colors periodically to compensate for the difference in colors�

This section explains how to perform calibration using [Adjustment Level] with 'Same for All Paper Types' for automatic gradation calibration� For more information on [Adjustment Level] for automatic gradation calibration, see "Adjustment for Image Quality and Finishing (Calibration)" > "Automatic Gradation Adjustment" > "Changing Adjustment Level" in the User's Guide�

Calibration after Purchase

The machine must be calibrated after you install it on your site� Use the following procedure to do the calibration�

Calibration on imagePRESS Server

The machine automatically corrects the color density every time it prints a certain number of pages to maintain stable gradations, densities, and shades of printed colors� When you print a large number of pages, you can increase the frequency of density corrections to minimize changes in colors�

Types of Paper You Can Use for Calibrating

You can use the following types of paper for calibration� If you want to use a different type of paper, you need to register the paper on the machine and the imagePRESS Server before performing a calibration� See "Calibrating for Paper You Want to Use for Printing" (p� 26) for the procedure�
