Capturing a Light
Illum Reader is a function to analyse the light.The purpose is to check the quality of your light into a viewing booths or in your viewing conditions.
1. Prerequisites
This function needs a spectrophotometer to work (Konica Minolta MYIRO, XRite Eye One Pro 1, 2 or 3)

2. How to use Illum Reader
Click on the icon "Create Light" in the toolbar of Coraye

Make sure your spectrophotometer is connected. When the "Read target" window appears, click on "I'm ready".

A new window will appear to calibrate your spectrophotometer.

Put the spectrophotometer into the calibration position Then click on the Start calibration button.
When the calibration is done, a new window will appear.

Be aware, you have to use the cap to read the light with the Konica Minolta MYIRO, I1 Pro 1, 2 & 3.
To capture the light, it is now sufficient to measure directly with the spectrophotometer. Successive measurements will be displayed one below the other.

You can make multiple measurements and rename them as you like.

When your measurements are finished, click on Save and quit. Yours lights samples will be add into the left column.

3. How to manage yours Lights samples
Click right on the color to Rename, Duplicate and Delete. Export option allow saving the color as a .sp file with spectral data. These .sp files are useful to share and backup yours light samples.

Measures can be export as a .sp file, to be saved on your hard drive.
4. What are the values associated with the measured sample?
When we read a light, we can get information like CCT, CRI, Ra, Brithness, Lab and x,y


To save your measure, click right on the measured light into the left bar, and select Export to save as a .sp file. As you see, you can also Rename, Duplicate or Delete the file when you click left on it.
5. Control your booth or your viewing condition
IllumReader can be useful to check uniformity, the color temperature and the light intensity into a booth, to check the conditions for viewing proofs, objects and prints. In the field of graphic arts, ISO standards have been defined to standardize the visualization conditions of prints. Knowing how to master one's light knows how to master one's color.

6. Light measurement can be use to calculate an Icc profile.
Create a profile from a standard reference7. Show yours reflectance curves in the Spectral Viewer.
It could be useful to compare reflectance curves of your color sample with a spectral curve of a specific light to understand the metamerism effect.
If you need to display the spectral curve of your measured light, you can use the Spectral Viewer
