KM CM-25 and CM-26 installation and use procedure

1) Konica CM-25 & CM-26 driver installation

The Konica Minolta CM-25/26 driver is only available in Windows version.
a) Driver download for KM CM-25/26
The drivers are included in the Coraye plugin of the CM-26 which can be downloaded from the dashboard: https://dashboard.coraye.com/plugins
Once the plugin has been downloaded, unzip it.
The driver is located in the folder: C:\....\KM-CM26-Pilot-WIN-1.0.3\lib\windows
When you connect the KM CM25 / 26 for the first time, it appears as "USB Serial Device" in Windows Device Manager.
This means that the driver for the CM25 / 26 has never been installed.
To install the driver, right click on "USB serial device" then select "Update driver"
Select "Browse my computer ..." to indicate the path of the folder in which the driver is located: C:\....\KM-CM26-Pilot-WIN-1.0.3\lib\windows\x64\
When you have indicated the path, click on "Next"
The driver will install, and "USB serial device" will become "Measuring Instruments". This means that the driver is correctly installed. Then click on the "Close" button

2) Modification of the port associated with the KM CM-25/26

To function properly, the serial port associated with the KM CM-25/26 must be COM4.
In the example below, the port assigned by Windows is the COM3 port.
We will have to reassign the COM4 port. Let's start by right clicking on "Measuring Instruments". Then select "Properties"
Click on the "Advanced" button to access the advanced parameters for COM3. Edit the Port Number and select COM4 from the list. Then click on the "OK" button to validate the modification.
COM4 port is assigned to KM CM-25/26

3) Installation of the KM CM26 Pilot plugin

The installation procedure is described in the procedure:
Since you have already downloaded the CM-26 plugin in the Dashboard, you can start with chapter 3 of the procedure

4) Using the KM CM-25/26 with Coraye

With the KM CM-25/26 you can:
    Measurement of samples with the connected spectrophotometer
    Measurement of samples with the spectrophotometer disconnected
    Measuring ranges to characterize impressions on materials such as glass, metal, etc...
To measure samples with Coraye, launch the color capture module.
Name your samples
Connection verification
At this stage you have the possibility:
    Download the measurements stored in the KM-CM 25/26
    or / and
    Use the KM CM-25/26 to capture color samples directly in Coraye via a USB connection.

5) Import of Measurements stored in CM-26

By clicking on the button "Import a reading", the samples stored in memory will be transferred to Coraye, then the memory of the spectrophotometer will be erased.

6) Measurements with the spectrophotometer connected in USB

Before clicking on the "Continue" button, remember to check the measurement mode you want to use (SCI or SCE) and also if you want to take into account the incidence of UVs.
Sélection du mode UV
Sélection du mode SCI ou SCE
Coraye does not allow launching the calibration from its interface. The calibration is therefore done on the KM CM-25/26 directly.
The KM CM-25/26 calibration procedure is explained in Chapter 2 of the manual, "Calibration" section. You will find links to download these manuals at the end of the chapter.
When you have completed the calibration, click on "The device is ready" to proceed to sample measurement.
For the rest, refer to the chapter "Capturing a color"

7) Creation of an ICC profile with a KM SC-25/26

The method of creating a profile with a KM SC-25/26 is identical to other spectrophotometers. Just follow the procedure "Create a profile"
However, there are some specifications to follow such as the size of the patches. We recommend a ration of 2
Remember to select the correct reading modes
The measurement of the range being done patch by patch, it would be a shame to notice at the end of the measurement, that you were mistaken in the choice of the SCI / SCE or UV100 / UV CUT400 mode especially after having measured 1000 patches. ..

8) Measurement of samples in a "Color Table"

The method for adding samples to a color table is the same as for other spectrophotometers.

9) KM-25/26 Owner's Manual

The user manuals can be downloaded from the following addresses: In English: https://www.konicaminolta.com/instruments/download/instruction_manual/color/pdf/cm-26dg_instruction_eng.pdf

10) SCI / SCE mode with or without UV

Mode SCI: Specular Component Included
Mode SCE: Specular Component Excluded Link from a Konica Minolta blog explaining the difference between SCI and SCE mode: https://sensing.konicaminolta.us/blog/specular-component-included-sci-vs-specular-component-excluded-sce/ Mode UV 100: UV source measurement to react optical brighteners
Mode UV CUT400: Measurement with UV filtered below 400 nm to ignore optical brighteners
Example of measurement carried out on a shiny Chromaluxe plate
A Gray sample was measured with the four reading combinations: The display of the reflectance curves allows you to view the difference in measurement between the different modes: - SCI - UV100 (Red) - SCE - UV100 (Blue) - SCI - UV CUT400 (Orange) - SCE - UV CUT400 (Cyan)
Note: On the right column you can directly obtain the information associated with the selected sample.
