2.1 Introduction
Congratulations! You have just acquired the portable plate measuring device
iCPlate2 made by X-Rite. This device solves one of the most difficult tasks
in the printing industry – quick and accurate quality control of the Computerto-Plate (CtP) process. iCPlate2 meets the needs for the most popular offset
litho and polyester plate types with AM and FM screening. With iCPlate2 XT
where applicable the dot diameter, screen ruling, the screen angle and the
logarithmic visual coverage are calculated and displayed. To avoid having
to check each individual measurement during the linearization of a CtP, the
iCPlate2 XT offers the possibility of measuring an entire curve with up to 100
sample points and then transferring it to a host PC. Beside standard iCPlate2
measurement values, iCPlate2 supports measurement values according to the
Fogra Measuring Bar FMB. Through a purchased password, the iCPlate2 X can
be upgraded to an iCPlate2 XT at any time.
The power-saving electronics and LED technology allow up to 30,000
measurements for each set of batteries (2 ordinary commercial AA batteries),
which means that no limits are placed on mobility.
With the icon-based, graphical user interface X-Rite offers the user a simple,
easy to understand operating concept. Included in the complete package are
the iCPlate2 Target and the Capture Tool software. With the Target, you can
check the device at any time and with the Capture Tool software data can be
copied into a word processor, a spreadsheet or another software program.
With the PlateQuality software, X-Rite offers an optional quality control
software to store and trace the measurements.
If you have proposals or ideas for improvements, we will be happy to receive
them. Please contact us via your official specialist dealer or over the Internet
(www.xrite.com).

2.6 Accessories
To perform and document quality control, it is often necessary to save
the measured data on a PC.
2.6.1 PlateQuality Software
The PlateQuality software stores, visualizes, and documents both
individual measurements and plate characteristic curve measurements.
This gives the operator a saved, visual dot reference to refer back to
when needed. Both measurement values and plate images are stored in
a database.
2.6.2 Capture Tool software
The Capture Tool software enables you to transfer the measured data
and binary images to your PC and to copy these into a given program
(e.g. word processor, spreadsheet). The screen dot as well as the
associated measurement values will be transferred and can then be
used for statistical analysis. This software is an ideal tool for
documenting measuring results.
2.6.3 iCPlate2 Target
The iCPlate2 Target is a long-term stable absolute reference. You can use
the iCPlate2 Target to test the device for its exactness, to carry out an
upgrade and if necessary to calibrate it.
2
The reference plate used by X-Rite is an extremely precise cut
glass substrate that is metal vaporized and, as is usual in
semi-conductor manufacturing, etched out. It is embedded in gray
plastic. The reference plate has a lifetime of two years. The expiration
date and the serial number are printed on the label.

Important:
Standard plates and polyester plates are
measured with a red LED.
Use of the blue LED or green LED is
only recommended when the coloring
of the plate has a strong proportion of
light pink
hues (e.g. AGFA N90A), as little image
contrast is obtained with red illumination.
Film is measured on a professional
illumination table in transmission. This is
why no choice of illumination is available
for the film setting.
3
With paper measurement, automatic
color selection allows for quicker work,
as no switching between the CMY
colors is required. Color contrast is very
slight with tones under 10%, so that
manual color setting is recommended.
For measurements on black, the
illumination colors needs to always be
manually selected.

3.5 Inputting a reference curve
The user can switch to ‘Input a reference curve’ by selecting the
function in the settings window (see section 3.3).
You will find the toolbar on the left side of the LCD.
An XY diagram of the defined sample points for the current
reference curve is shown on the LCD. The X axis corresponds to the
nominal value and the Y axis to the reference value. The currently
selected nominal value is indicated on the lower end of the Y axis
and the associated reference value on the upper end, provided that a
sampling point for the reference curve is planned at this location.
All reference values are reset by selecting the function.
You preset the nominal value using and .The position of the
nominal value is marked by a small black arrow on the X axis of the
diagram. After initially selecting the nominal value select to
input the value. Thereafter the increment and decrement
functions will be highlighted in the toolbar. Per default, the reference
value is the same as the nominal value. To enter a 45° reference
curve, successively set the nominal value to the value of the patches
being measured, select the function and press <ENTER> button.
To move to the next sampling point, select .
You delete a value using and .
The position of the nominal value is marked by a small black arrow
on the X axis of the diagram. After initially selecting the nominal
value select to delete the value.
Example: Inputting a reference curve with the sampling points 5, 10,
30, 60 and 90.
• Select the reference curve window from within the settings window.
Select the function with the <UP> or <DOWN> button and
•
execute this using the <ENTER> button. All reference values are reset.
• Select the function and execute this function repeatedly until the
nominal value is equal to 5% (press <ENTER> button 5 times).
• Select the function .
• The default value for this sample point corresponds to the nominal
value. Now select the function to increment or to decrement
and press the <ENTER> button. If the reference curve is altered at
least once, the iCPlate2 will create a sample point for the reference
curve in this position and save this. The vertical gray line at this
location in the diagram is adjusted simultaneously when the reference
value is changed.
Select the function and execute this function repeatedly until
•
the nominal value is equal to 10% (press <ENTER> button 5 times).
Change the reference value using the steps described for 5%.
•
Set further reference values in the same way.
•
When all of the desired settings have been made, change to the standard
window by using
Important:
In normal circumstances the reference
value is set to be equal to the nominal value to obtain a linear plate copy.
However, for certain applications a plate
type dependent process calibration
(pre-compensation) on the plate copy
may be desirable. In this case iCPlate2
offers the possibility of defining the
reference curve in deviation from the
45° straight line.

Important:
For repeatable measurements, it is
recommended to hold the measuring head on the right and left side
approximately at the level of the locking element and to lower it. Incomplete
lowering of the measuring head leads
to a blurred image and consequently to
an inexact measurement result.

3.6 Measuring
3.6.1 General
Position the instrument by means of the positioning target on the
patch and lower the measuring head. The symbol will appear in
the LCD. Keep the measuring head lowered until the measurement
value is dis played. If the measuring head was released before the
completion of the measurement, indicated by the blinking
symbol, the measurement must be repeated.
Important: For precise measurements, please always make sure the medium
and the device is positioned on a flat and stable surface. Please always position
the entire instrument on the medium (the 4 feet and the measuring head).
The measuring device shows the measurement result after a
successful measurement.
You will find the toolbar on the left side of the LCD with
the following functions:

Dot diameter in µm (based on a circular dot of the same
surface area), provided that a closed dot was present
Screen angle in °
Visual coverage
All or only some of the measurement results are shown depending
on the patch measured and the algorithm (regular or stochastic
screening).
You will find the status of the device settings on the lower right
section of the display (see section 3.2.3.6 for the explanation of
the symbols).
Important:
In a regular screen, the screen ruling,
dot size and screen angle will always
be shown if the dot area has closed
dots (highlights and shadows). These
parameters are not shown for middle
tones, especially for chain dots.
The visual coverage is a ‘density’
measurement, which is not compatible with any current standard and can
only be used for comparative analysis.
For density measurement, we recommend using a X-Rite Densitometer
conforming to standards.
Only the dot area is usually
determined in stochastic screens.
However, use of image analysis
algorithms makes it possible to
measure individual dot sizes in
stochastic screens as well. The
dot size will be displayed if the
stochastic screen is set and screen
tones < 10% are measured. This
means the laser image quality can
be verified easily.

3.6.2 Calibration
As the iCPlate2 calibration is done automatically, no calibration
or “zeroing” on the plate is needed. After inputting into the
device the appropriate settings, measurements can be executed
without any further calibration.
A zeroing on the plate is however required for the “Visual
Coverage” value. This zeroing is done by a measurement on the
medium (e.g. plate ground).
To check the absolute accuracy of the iCPlate2, X-Rite
offers the iCPlate2 Target. With the help of this tool, the device can
be checked and calibrated (see section 2.6.2).
3.6.3 Measuring standard plates
Standard plates and polyester plates are measured with a red LED.
Use of the blue LED or green LED is only recommended
when the coloring of the plate has a strong proportion of light
3
pink hues (e.g. AGFA N90A), as little image contrast is obtained
with red illumination.
Important:
As the measurement algorithm is designed and optimized for finding dots in a
picture, measuring a 0% patch or a 100% patch can be difficult since the
software is designed for having the best possible performance for dot measure ments. For this reason, and in certain cases only, the displayed measurement
value for the 0% or the 100% may not be correct. The measuring range for full
precise readings is limited to 1% to 99%.
Therefore, incorrect 0% or 100% patch measurement result that may occur in
certain cases do not indicate that the instrument is functioning poorly. Please
use the iCPlate2 Target to check the accuracy of the device (see chapter 2.6.2).
iCPlate2
3•Operation
3.6.4 Measuring polyester plates
Standard plates and polyester plates are measured with a red LED.
Use of the blue LED or green LED is only recommended when the
coloring of the plate has a strong proportion of light pink hues, as
little image contrast is obtained with red illumination.
Important: Due to the grainy background of polyester plates the repeatability may
be up to +/- 0.8 %. For the same reason and because of the algorithms used for
measuring dots, measurements below 5% or on a 100% patch can sometimes be
incorrect. Therefore, the measuring range for exact readings is limited to 5%
to 99%. Please note that incorrect measurements for 0% or 100% patches do
not indicate that the instrument is functioning poorly. If you were to get incorrect
measurements for 0% or 100% patches, please use the iCPlate2 Target to check
the accuracy of the device (see chapter 2.6.2).
3.6.5 Measuring film
Film should be measured on a professional illumination table in
transmission mode. This is why no choice of illumination is available
for the film setting.
Important: Please make sure that the light table is equipped with a flat and
stable glass.

3.6.6 Measuring paper
For paper measurements, automatic color selection allows for
quicker work, as no switching between the CMY colors is required.
Color contrast is very slight with tones under 10%, so that manual
color setting is recommended. For measurements on black, the
color (K) must always be selected manually.
The iCPlate2 is equipped with a video camera, which measures the
geometrical dot size, relevant for plate readings. For prints, the
densitometric dot size needs to be measured, as this measurement
corresponds to the visual impression. Therefore, the iCPlate2 is
not the ideal device for measurements of the dot area on paper.
Nevertheless, it can be used for visual dot analysis of prints.

3.6.7.4 Screen angle
Hold the iCPlate2 parallel to the edge of the plate to get a correct
value of the screen angle in degrees.
Important: The screen angle is not shown for FM screening and for middle tones,
especially for chain dots in AM screening. In a regular screen, the screen angle
will always be shown if the dot area has closed dots (highlights and shadows).
3.6.7.5 Visual Coverage
The visual coverage is a ‘density’ measurement, which is not
compatible with any current density standard and can only be used
for comparative analysis. For proper density measurements, we
recommend using a X-Rite Densitometer conforming to
standards.
For the “Visual Coverage” value, a zeroing on the medium is
needed. The zeroing is done by a measurement on the medium
(e.g. plate ground).

Example: Measuring a plate characteristic curve with the sample
points 5, 10, 30, 60 and 90 (45° reference curve):
• Select the function with the <UP> or <DOWN> button and
execute this using the <ENTER> button. All reference values are
reset. The nominal value 5% and the reference value 5% are shown.
• Measure the 5% patch. The measured value is shown at the top
edge of the Y axis and the 5% reference value is shown below it.
The nominal value of 10% and the reference value of 10% are
shown for the next patch.
• Measure the 10% patch. The measured value is shown at the top
edge of the Y axis and the 10% reference value is shown below it.
The nominal value of 30% and the reference value of 30% are
shown for the next patch.
• Should you have measured the 20% patch instead of the 10%
patch, put the measurement cursor back by one patch by selecting
the function with the <UP> or <DOWN> button and then
