Calibrating a densitometer The reflection densitometer must be calibrated to provide accurate density readings. Before using, you must follow the instructions that are provided by the manufacturer to calibrate the densitometer. The densitometer used must comply to the spectral responses defined by ANSI PH2.18 - 1985 and ISO 5/3 - 1984. The densitometer should not have a polarizing filter. The Greytag Macbeth model D19C has a polarizing filter and should not be used. Densitometers which are appropriate to use include the X-Rite Model 504, 508, or 400B. The densitometer should be used in Absolute Density mode for measurements. This procedure describes how to calibrate the X-RITE 400B (1060) densitometer, using the Reflection Reference Card (part number 400-62). Since the X-RITE 400B is now obsolete, this information is provided as reference. The Reflection Reference is the card you use to calibrate the densitometer. You will use only the circular patches labeled 1 (white reference) and 3 (black reference). The densitometer should be calibrated periodically, or whenever the instrument displays RECAL. You should store the Reflection Reference Card in its envelope. 1. Press the FUNCTION and ENTER keys in sequence, then release. After the version and copyright notices appear, the display will show N cal O Y. 2. Press the ZERO key and release. After the version and copyright notices appear, the display will show N qcal Y. 3. Press the FUNCTION key and release. SET LO is displayed momentarily, followed by X.XX, where X.XX should be the white patch ORTHO value from the Reflection Reference card. 4. If X.XX matches the white patch ORTHO value for your reflection reference, press the ENTER key. If X.XX does not match, hold down the ZERO key and press either the FUNCTION or the ENTER key. Decrease (FUNCTION) or increase (ENTER) the value until the correct number is displayed. When finished, release the keys and press Enter. SET HI is displayed momentarily, followed by Y.YYH , where the Y.YY part of the value should be the black patch ORTHO value from the Reflection Reference card. 5. If Y.YY matches the black patch ORTHO value for your reflection reference, press the ENTER key. If Y.YY does not match, hold down the ZERO key and press either the FUNCTION or the ENTER key. Decrease (FUNCTION) or increase (ENTER) the value until the correct number is displayed. When finished, release the keys and press Enter. 6. When you see READ WHT displayed, center the circle on the base of the densitometer over the white patch (the one labeled "1") on the Reflection Reference. Push the head down and then release it to establish the white patch Optical Density. If INVALID displays, repeat the measurement. 7. When you see READ BLK displayed, center the circle on the base of the densitometer over the white patch (the one labeled "3") on the Reflection Reference. Push the head down and then release it to establish the black patch Optical Density. If INVALID displays, repeat the measurement. Chapter 29. Configuring the Halftone Management System 285

Calibrating a densitometer

The reflection densitometer must be calibrated to provide accurate density

readings. Before using, you must follow the instructions that are provided by the

manufacturer to calibrate the densitometer. The densitometer used must comply to

the spectral responses defined by ANSI PH2.18 - 1985 and ISO 5/3 - 1984. The

densitometer should not have a polarizing filter. The Greytag Macbeth model

D19C has a polarizing filter and should not be used. Densitometers which are

appropriate to use include the X-Rite Model 504, 508, or 400B.

The densitometer should be used in

Absolute Density

mode for measurements.

This procedure describes how to calibrate the X-RITE 400B (1060) densitometer,

using the Reflection Reference Card (part number 400-62). Since the X-RITE 400B is

now obsolete, this information is provided as reference.

The Reflection Reference is the card you use to calibrate the densitometer. You will

use only the circular patches labeled 1 (white reference) and 3 (black reference).

The densitometer should be calibrated periodically, or whenever the instrument

displays RECAL. You should store the Reflection Reference Card in its envelope.
