Calibrating the Printer
This section includes instructions for calibrating the family of Kodak Professional
CRT Printers.
Kodak provides calibration applications for Windows NT and, except for the
KPDM II, Macintosh systems.
See “Installing the Calibration Software” on page 2-2 for installation instructions.
See Section 2, Using Additional Calibration Features, for details about the
windows and dialog boxes for the application software and for additional
procedures not performed with each calibration.
Calibration is the process for creating and maintaining a Look-Up Table (LUT) that
produces the correct color balance for all images printed on the Printer. There is
sufficient variation among printers that each printer must be calibrated separately.
Over time, there are several conditions which can contribute to calibration
deviation. To prevent this potential deviation, it is recommended that you calibrate
the Printer when you change paper type (paper emulsion, surface, lot number,
and width) or when the calibration test target print is out of tolerance.
IMPORTANT: For the CRT Printer Family calibration, the term “device” refers to a
setup for a specific paper type/scale combination.
You can add, update, and delete devices as needed.
Before calibrating, make sure that:
• within the Kodak Professional Device Calibration software, for each paper
type/scale that your lab uses:
— a device is defined (see “Adding a Device” on page 2-10)
— any needed changes to the configuration file are in place (see “Editing the
Device Configuration File” on page 2-17)
— frame counts are determined (see “Determining Frame Counts for a
Device” on page 2-32)
• the paper path is threaded
• no other printer applications are active
• the densitometer is connected and calibrated
• the paper processor is in control
• the printer status as shown at the OCP is “Ready” (not “Printing”)
1-1
NOTE: If the Printer is threaded and its status is Offline, press
Jog&Start at the OCP to advance the paper and change the status to
Ready.
During calibration, when making a print of the test target:
•
wait 15 minutes or longer after exposing a test target before processing to
stabilize latent image keeping (LIK)
•
read the second of the three test target prints with an X-Rite DTP36
densitometer.
Starting the Device Calibration Software
1. From the desktop of the host computer, open the KODAK PROFESSIONAL
Device Calibration application.
The display shows the Device Calibration window. If no device icon is in the
window or there is no icon for the device you need to calibrate, see “Adding a
Device” on page 2-10.
Device icon
2. Select the icon for the device (printer and scale) to calibrate.
3. Click the Calibrate icon.
1-2
The display shows the CRT Print Family Calibration Application window.
Starting the Calibration Application and Exposing a
Test Target
IMPORTANT: The settings in the configuration file for the selected device
determine some of the actions and messages in this procedure.
The configuration file is specific to your lab and its operations. For
more information about the configuration file, see “Editing the
Device Configuration File” on page 2-17.
The instructions for the calibration procedure give options at each step. However,
the software is designed so that once you select Go to begin, the default is
highlighted so you can select the simplest option in each case. This means you
can calibrate with minimum intervention or decision-making.
1. Click Go on the Calibration window.
NOTE: If needed, you can cancel the calibration application at any time when
the Stop icon (red traffic light) lights.
1-3
The Downloading LUTs and Exposing Test Print status icon highlights and (if
“Ask if processor is in control?” in the configuration file is On) the display
shows the Process In Control dialog box below.
IMPORTANT: The processor is a critical component of printer calibration;
monitor it on a regular basis. Calibration can not be accurate if
the processor is not in control.
2. From the Process in Control dialog box above, click Yes (or No to exit the
calibration procedure).
The display shows the Choose PaperPak dialog box.
1-4
3. Either:
• with the selected PaperPak highlighted, click Load Selected PAP, or
• click Load Custom PAP; then browse the standard file dialog that allows
PaperPaks to be imported from other areas on the hard disk or from a
removable disk; select the PaperPak file you need.
The default location for PaperPaks is the CalLUTS folder.
(Click Cancel on the Choose Start PaperPak dialog box to exit.)
When the PaperPak has been selected, the display shows the Confirm/Edit
Frame Counts dialog box.
1-5
4. Make sure the frame counts are correct, as established by your lab.
5. Click OK, or if needed, edit the frame counts and then click OK.
NOTE: During the initial setup process for the Printer, your lab tests and sets
frame counts. See “Determining Frame Counts for a Device”
on page 2-32.
The display shows the Choose Starting LUT dialog box. The highlighted LUT
is the most recent calibration LUT. If this is the initial calibration for the device,
the 12-Bit Factory Default is highlighted.
6. Either:
• with the starting LUT highlighted, click Load Selected LUT, or
• click Load Custom LUT; then browse the standard file dialog that allows
LUTs to be imported from other areas on the hard disk or from a removable
disk; select the LUT file you need.
The default location for calibration LUTs is the CalLUTS folder.
(Click Cancel on the Choose LUT dialog box to exit.)
1-6
After the LUT file has been selected, “The LUT was sent successfully” shows
on the status bar. With the PaperPak and the LUT, the Printer can expose a
print of the test target.
NOTE: The factory default for the number of copies printed is 3.
When the prints have been exposed, the Scanning Processed Print with
Densitometer icon highlights.
7. At the OCP, perform a Batch Cut.
8. Wait for latent image keeping (LIK) to stabilize before processing. The
minimum suggested time is fifteen minutes.
9. Send the test target prints to be processed.
Continue with “Obtaining Densities.”
1-7
Obtaining Densities
There are three methods for obtaining densities:
•
•
•
from a file
from a densitometer
from a centralized densitometer (NT only and only if the Centralized
Densitometer application is installed on your network)
The contents of the device configuration file determine which method you use
(see “Editing the Device Configuration File” on page 2-17).
Obtaining Densities from a File
If the configuration settings include obtaining the density data from a file, the
display shows the Waiting for Density File dialog box.
If the configuration settings do not include obtaining the density data from a file,
go to either:
•
•
“Using the Densitometer to Read Densities” on page 1-9 or
“Obtaining Densities from the Centralized Densitometer (NT Only)”
on page 1-11
NOTE: To create a density file, see “Creating a Density File for Use with Calibration”
on page 2-55.
1. Click OK to continue with the calibration process.
2. Go to “Completing the Calibration Procedure” on page 1-12.
1-8
Using the Densitometer to Read Densities
For the most accurate reading, cut the second of the three test target prints and
read its densities with an X-Rite DTP36 densitometer, as specified in this
procedure.
1. Trim the processed test target print on the dashed line and along the top so
the print passes through the densitometer at the correct locations.
2. Align the pass 1 arrowhead on the print (shown below) with the vertical
groove on the front of the densitometer.
3. Put the print firmly in the densitometer. Keep a slight pressure on the print as
it moves through the densitometer until you feel a resistance and the display
shows “Reading.”
A short beep from the densitometer, followed by “Pass 1 of 4 OK”, indicates a
successful read. “Read EKT-CRT PA2” is displayed next, indicating the
densitometer is waiting for the next pass.
A long beep with a message to re-read the pass indicates an unsuccessful
read. Read the same pass through the densitometer again. If the read
continues to be unsuccessful, cancel, then restart the calibration.
1-9
4. When the read is successful, repeat steps 2 and 3 until all four passes are
complete. Align the arrowhead at passes 2, 3, and 4, respectively.
For instructions on using the densitometer, see the densitometer manual.
When “Density values received” shows on the status bar, continue with
“Completing the Calibration Procedure” on page 1-12.
If the Density Readings are Unsuccessful
If either of the two dialog boxes below are displayed, click Retry after making sure
the densitometer is on and the connection is secure.
1-10
Obtaining Densities from the Centralized
Densitometer (NT Only)
NOTE: For more information about installing and using the Centralized
Densitometer Application, see Section 3, Installing and Using the
Centralized Densitometer Application.
If the configuration settings include obtaining the density data from the centralized
densitometer application, a message is displayed in the status bar.
1. Open the Centralized Densitometer Application. The display shows the
Centralized Densitometer Application window.
2. Highlight the device.
3. Click Measure or select Operations->Measure to measure the target images.
1-11
4. At the densitometer, measure the densities (see “Using the Densitometer to
Read Densities” on page 1-9).
When the densities are measured, the status bar on the Centralized
Densitometer Application window displays “Ready.”
The measured densities are automatically sent to the CRT printer’s host
computer.
Continue with “Completing the Calibration Procedure.”
Completing the Calibration Procedure
The Calculating LUTS & Downloading to the Printer status icon highlights.
1. If calibration is in tolerance, the display shows the LUT Attributes dialog
box.
a. Enter a name or comment in the dialog box. The comment you enter will
appear on the Send LUT to Printer dialog box to identify the LUT file with a
name that is meaningful to you (up to 75 characters).
b. Click OK.
The new printing LUT is calculated and downloaded. The status bar shows
“Calibration Complete.”
2. If calibration is out of tolerance, it may be necessary to run four or more
iterations of the calibration cycle to achieve a successful calibration.
If the print densities are out of tolerance, the display shows a graph, allowing
you to select the type of data and planes that you want to see displayed.
a. Click OK.
1-13
If specified in the configuration file, the display shows a list of options.
Re-read the densitometer values is most useful when the graphs show
an unusual plot. Rereading the test print lets you validate the graph, then
returns you to the Out of Tolerance dialog box.
Iterate again using a newly calculated calibration LUT allows you to
print another test print with the newly calculated LUT and see if this brings
the printer within tolerance.
Calculate and download a printing LUT and stop: When you select this
option, the LUT is calculated and the file is saved with the creation date
and time as its name.
Cancel and return the printer to its original state saves nothing. Any
corrupted data created after you saved the last time is thrown away.
b. Select one of the four options to try to complete the calibration
successfully.
Exiting the Calibration Procedure
To exit the Calibration window, select Quit from the File menu on the Calibration
window.
To exit the Device Calibration window, select Quit from the File menu on the
Device Calibration window.

Using Additional Calibration Features
Determining Frame Counts for a Device
IMPORTANT: Determining frame counts must be done before any prints can be
made. For each device, it is a one-time procedure.
About Frame Counts
A frame is a minimum unit of exposure time used in a CRT Printer. Frame counts
are represented by integers. An increase in frame counts increases the exposure
time and decreases productivity.
You need to determine frame counts as the first step to calibrating the Printer for
each paper type and scale.
The purpose of determining starting frame counts is to determine the combination
of red, green, and blue frame counts that will produce optimum contrast for a
paper type. This is usually a DMax (patch 20 or black) value within a range of 2.1
to 2.3 density units.
The calibration software contains default frame counts for Digital III Paper on the
selected printer. However, optimum frame count values vary among printers and
among paper types. Because contrast is an important factor in producing quality
prints, you will want to fine-tune the frame counts.
It is important to note that the red and green values and the green and blue values
interact. This means changing the red value will not only change the red density,
but will also change the green density. Changing the green density changes the
blue density.
2-32
Using Additional Calibration Features
Using the Software to Calculate Frame Counts
1. From the desktop of the host computer, open the KODAK PROFESSIONAL
Device Calibration application.

IMPORTANT: The processor is a critical component of printer calibration;
monitor it on a regular basis. The calculation of frame counts can
not be accurate if the processor is not in control.

Creating a Density File for Use with Calibration
During calibration, you have the option of obtaining density data from a file or by
scanning a processed test target through an X-RITE DTP 36 densitometer. The
option is determined by the entry in the calibration configuration file. If the
configuration file is set up to receive density data from a file and you are creating
the file:
1. Scan the print into your densitometer.
2. Save the data to file using the density data file format specification (see “File
Formats” below). The Kodak Professional Device Calibration software does
not perform this function.
3. Move the density data file that you just saved to the “Dens” folder within the
device folder for your specific device. The filename should match the Density
Source File selected on the Density Source tab of the Edit Configuration
window (see “Editing Information on the Density Source Tab” on page 2-21).
File Formats
NOTE: If a file contains data in a tabular format, each entry may be separated by
multiple spaces and tabs; however, when the file is saved by the application,
each group of multiple spaces and tabs is automatically converted to a
single tab.

Troubleshooting
Code
Message
Explanation
<10>
LAMP_MARGINAL
The lamp output is at approximately 50% of its original
brightness. Strip readings can still take place, but to maintain
proper accuracy and repeatability, replace the lamp as soon
as possible.
<11>
LAMP_FAILURE
The lamp is either burned out or its output is at a level too low
for acceptable readings. The densitometer will not read strips
until the lamp is replaced and the densitometer is recalibrated.
<12>
STRIP_RESTRAINED
During calibration, the calibration strip was held or restrained
as it passed through the unit. Do not hold the strip as it is
reading and make sure the read path is clear of any foreign
matter.
<13>
BAD_CAL_STRIP
During calibration, the calibration strip was unrecognizable.
The strip may have been inserted backwards, upside down, or
held so that it slipped on the internal rollers. This also may be
an indication that the strip needs to be replaced.
<14>
MOTOR_ERROR
During calibration, a problem was detected with the drive
motor. This can occur if the strip is held back while reading.
<20>
INVALID_READING
The strip just read was not recognized by the densitometer.
<21>
WRONG_COLOR
After a strip reading, the step wedge just read was not the
color specified for that pass or strip as defined in the
densitometer editor menu.
<23>
NEEDS_CALIBRATION
The calibration check that was done immediately after reading
a strip indicated that the unit needs calibration. This occurs
when the reading taken from the opal glass after the strip exits
the unit differs from the reading taken during calibration by
more than the internal tolerance (default is 0.1 X, Y, or Z). The
tolerance can also be changed by the RCI command CC
(Check Cal tolerance).
A-12
March 2001
Troubleshooting
Code
Message
Explanation
<26>
NO_VALID_DATA
The measure type is set to CONT and the strip that was read
contained nothing but base material. Base material is defined
as measuring less than 0.5D in the visual channel. For
negative (black) based materials, base material is defined as
measuring less than twice the reflectance of a measurement
taken near the trailing edge of the strip. the densitometer uses
a measurement taken at about 0.25 inches from the trailing
edge of the strip to determine if it is positive or negative
based. Any measurement greater than 10% reflectance is
considered positive based; anything else is considered
negative based.
<27>
BAD_PATCH
If the Pattern Recognition comparison window is set to 0 or 1,
this error may result when a single patch on the strip is bad
due to dirt, smears, creases, etc. (See explanation of CW
command for more information.)
<30>
BAD_STRING_LENGTH
A strip definition string received as part of the DS (Define
Strip) RCI command did not contain the correct number of
characters.
<31>
BAD_CHARACTER
A non-printable character was received in one of the name
fields (strip name or pass name). Printable characters are in
the range 0x20 to 0x7E, inclusive.
<32>
BAD_MEAS_TYPE
The value for the measure type field was greater than 3. Valid
values are 0 through 3.
<33>
BAD_COLOR

Appendix B: Manually Determining
Frame Counts
When choosing frame counts to reach a target DMax, choose the red, green, and
blue values that are close to, or slightly higher than, the optimum DMax range (for
Digital III paper, red – 2.25, green – 2.20 and blue – 2.15 are optimum).
NOTES: Not all photographic papers support a DMax of above 2.1 in all three
colors.
The combined characteristics of the cathode ray tube (CRT) and Digital
Photographic paper results in a very low number of frame counts
needed for the green exposure. This produces a coarse adjustment of
the green Dmax. When determining the green frame counts, select the
first value that produces a density higher than the Dmax aim, even
though the difference is significant. The calibration software has
sufficient range to accommodate the higher Dmax.
When you enter frame counts in this procedure for a Digital Multiprinter with
Digital III paper, use the initial values for the most frequently used scales
(magnifications) that are suggested below:

The recommended procedure for determining the best frame counts is to create
three test targets, each one using:

•
the recommended values from the chart above
•
the recommended values minus one
•
the recommended values plus one
B-1
Manually Determining Frame Counts
For example for 8R, you would send test targets with these sets of frame counts:
R G B
6 2 2
5 1 1
7 3 3
Next, you would process the test prints, then measure and record DMax for each
test target. The test target that produces the best DMax values (for Digital III
paper: red – 2.25, green – 2.20, blue – 2.15) determines the starting frame counts.
Procedure to Determine the Frame Counts for a Scale
Use this procedure with Macintosh and Windows NT systems.
1. Press Jog&Start at the operator control panel (OCP) to put the Printer in
“Ready” mode.
2. On the Device Calibration window, select the icon of the device for which you
are determining frame counts. (If the device is not on the Device Calibration
window, add it; see “Adding a Device” on page 2-10)
3. Click Calibrate.
The display shows the Calibration window.
4. From the Calibration window, in sequence:
a. Click Send PaperPak to send the PaperPak (see “Sending PaperPaks” on
page 2-46) with the recommended frame counts.
For example, if you are determining frame counts for an 8R device, edit
the frame counts to be 6, 2, and 2.

Manually Determining Frame Counts
IMPORTANT: When sending the LUT file, make sure you select “Send
Custom” then navigate to the CalLUTS folder and choose the
default12.cal file.
b. Click Send LUT to send the LUT file (see “Sending LUTs” on page 2-48).
c. Click Send Target to send the Test Target (see “Sending Test Targets” on
page 2-49).
5. Repeat step 4 (a, b, and c) twice for the second and third set of frame counts
(in the example, the values would be 5, 1, 1 and 7, 3, 3).
6. Process the test targets.
7. Set up the densitometer to read the test target:
a. To go to the main menu of the densitometer, simultaneously press the two
right-most buttons.
b. Select PAP from the main menu on the densitometer.
8. Send one pass of the first processed test target through the densitometer and
record the Dmax for each color:
a. To go to the main menu of the densitometer, press the two right-most
buttons simultaneously.
b. From the main menu of the X-Rite DTP36 densitometer, press [P1].
c. Press [Data].
d. Read the DMax patch (Pass 1).
e. Record the values directly on the test target.
9. Repeat step 8 for the second and third test targets.
10. Determine which set of frame counts gave the best DMax reading:
• Using the 8R values as an example, the recorded DMax values are:
R
G
B
R
G

2.20 2.46 2.26
5
1
1
1.80 1.55 1.92
7
3
3
2.44 2.68 2.35
In this example, the red and blue values are within the preferred 2.2 to 2.3
range.
Although the green value of 2.46 is slightly higher than the preferred
maximum of 2.3, a frame count of 1 gives a DMax of only 1.55 and a frame
count of 3 gives a DMax of 2.68, which is even higher than 2.46.
Therefore, in this example the starting frame counts for 8R are 6, 2, 2.

Manually Determining Frame Counts
•
Using 10R values as an example, the three test targets are sent with the
frame counts below and produce the DMax values shown:
R G B
R
G
B
8 2 3
1.85 2.09 2.24
7 1 2
1.50 1.16 1.96
9 3 4
2.12 2.51 2.35
In this example, the blue value of the second print is within the 2.2 to 2.3
range.
The green value of 2.51 from the third print is as close as possible to the
preferred values (frame counts must be integers; a frame count of 4 would
produce an even higher DMax).
Therefore, the starting 10R frame counts for green and blue are 3 and 3,
with red not yet determined (none of the frame counts produced a DMax of
2.25).
In this example it is necessary to send two more test targets.
R G B
10 3 3
11 3 3
R
G
B
2.26 2.52 2.25
2.38 2.53 2.22
So, for 10R the starting frame counts are 10, 3, 3.
You have determined the best frame counts for this scale. Use these frame counts
for calibrating the Printer for this device.
