Konica Minolta CM-26 CM-25

Installing the Konica CM-25 & CM-26 driver

The Konica Minolta CM-25/26 driver is only available in Windows version.

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

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 will appear as " USB Serial Device " in Windows Device Manager.

This means that the CM25 / 26 driver has never been installed.

To install the driver, right click on " USB serial device " then select " Update driver "

image-1629969482755.png

Select " Browse my computer ... " to indicate the path of the folder in which the driver is:
C: \ .... \ KM-CM26-Pilot-WIN-1.0.3 \ lib \ windows \ x64 \

When you have indicated the path, click on " Next "

image-1629969563633.png

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

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 COM3.

You 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 the COM3.
Modify the Port number and select COM4 from the list.
Then click on the " 
OK " button to validate the modification.

Installation of the KM CM26 Pilot plugin

The installation procedure is described in the procedure: Installing and managing Plugins

To find out more, see the chapter : Installing and managing plugins

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


Using the KM CM-25/26 with Coraye

With the KM CM-25/26 you have the possibility to perform:
- The measurement of samples with the connected spectrophotometer
- The measurement of samples with the disconnected spectrophotometer
- The measurement of ranges to characterize prints on materials such as glass, metal,
etc ...

To measure samples with Coraye, launch the color capture module.

For more information, see chapter : Capturing a color

Checking the connection

At this step you have the possibility:
- To download the measurements stored in the KM-CM 25/26 or / and
- To use the KM CM-25/26 to capture directly in Coraye, the color samples via a USB connection .


Import of measurements stored in the CM-26

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

Measurements with the spectrophotometer connected via 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.

Selecting SCI or SCE mode

Coraye does not allow you to launch the calibration from its interface.
The calibration is therefore done on the KM CM-25/26 directly.

The procedure for calibrating the KM CM-25/26 is explained in chapter 2 of the manual, section "Calibration".
You will find the links to download these manuals at the end of the chapter.

When you have performed the calibration, click on " Instrument is ready " to proceed to sample measurement.

For the rest, refer to the chapter " Capturing a color "

For more information, see chapter: Capturing a color

Creating 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.
All you have to do is follow the " Create a profile " procedure.

To find out more, see the chapter: Creating a profile from a standard test pattern

 

Do not forget to select the right 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 made a mistake in choosing the SCI / SCE mode or UV100 / UV CUT400 especially after measuring 1000 patches ...


Measuring samples in a "Color Table"

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

For more information, see chapter: Color table

SCI / SCE mode with or without UV

SCI Mode: Specular Component Included

SCE Mode: Specular Component Excluded

Link to 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: Measurement with UV source to react optical brighteners

CUT400 UV mode: Measurement with filtered UV below 400 nm to ignore optical brighteners

Example of measurement carried out on a glossy Chromaluxe plate

A gray sample was measured with the four reading combinations: The display of the reflectance curves makes it possible to visualize the difference in measurement between the different modes:
- SCI - UV100 (Red)
- SCE - UV100 (Blue)
- SCI - UV CUT400 (Orange)
- SCE - UV CUT400 (Cyan)
