Using the SpectroPad with Maxwell
These instructions assume the user has a basic knowledge of Maxwell and the Maxwell Client.
These instructions are for USB connection with the SpectroPad. (Wifi connection is explained in separate instructions.)
Enter Account Details
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424202952217.png" width="560" height="450" alt="" />
Enter your Maxwell username and password under Setup > Maxwell Client > Enter Account Details.
Install Target Format file
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424204900368.png" width="424" height="361" alt="" />
The SpectroPad and the Maxwell Client must have a reference file that defines what the measurement target looks like.
To install a target format file, click Maxwell Client > Open Target Folder, and
install a Barbieri .zip file produced by the Barbeiri Chart Generator into the Barbieri SpectroPad folder.
Add a Track
To add a track to be used with the SpectroPad, click on the plus button and follow the browser to add a track from Maxwell.
(For more help on adding a new track in Maxwell, click here:
http://www.colorwiki.com/wiki/Maxwell_Client_Tracks
Click on the new track in the left column that you just added to see the details pane.
Spectropad autoSync
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424204571133.png" width="501" height="391" alt="" />
Check the autoSync checkbox and choose the target to be used with this SpectroPad track.
Connect SpectroPad
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424205879060.png" width="506" height="300" alt="" />
Connect the SpecroPad to the computer using the USB cable or Wifi. Click the SpectroPad under Color Instruments on the left column, and click the "Connect" button.
Sync SpectroPad
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424205954552.png" width="440" height="166" alt="" />
Click the Sync SpectroPad button to move files to the SpectroPad or to harvest measurements from the SpectroPad.
Choose track
<img src="images/Using_the_SpectroPad_with_Maxwell/155_1517.png" width="375" height="258" alt="" />
Once synced, the track should show up under the DOC module on the SpectroPad screen.
Follow the usual procedures to calibrate the instrument, and measure the target using the track.
Measure
<img src="images/Using_the_SpectroPad_with_Maxwell/155_1519_g.png" width="390" height="291" alt="" />
Note that the SpectroPad measures from the bottom row to the top row of the target.
Close and save
<img src="images/Using_the_SpectroPad_with_Maxwell/155_1521_g.png" width="381" height="271" alt="" />
When finished measuring, the operator can scroll through the list of measured results.
Clicking the Close button will save the measurement.
Sync with Client
In order to transfer the saved measurements to Maxwell, click the Sync button on the Client.
Measurement Result
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1424207818244.png" width="333" height="354" alt="" />
Measurement will result in a pass / fail report which can be printed onto a label or viewed on screen before being sent up to the Maxwell website.
More
<img src="images/Using_the_SpectroPad_with_Maxwell/media_1426792960085.png" width="560" height="60" alt="" />
More measurements can be made, using these same steps. The history of these measurements can be tracked in Maxwell by clicking on the blue links below the Verification History. The Trend report in Maxwell is very useful for seeing day to day changes in measurements.

I just find this rather cool. Letters and numbers that look the same, when viewed from different angles. They call it "4D type":

In July, 2011 Apple released version 10.7 of their operating system ("Lion"). This OS does not support the translation protocol known as "Rosetta" which has been used to run many Power PC applications. With Lion, several common color management applications will no longer run. Here is a table listing several of these applications, whether they will be Lion compatible, and whether there is an alternative that has the same function.

NEC - MultiProfiler - Typical workflow & Print emulation
Apparently the neat thing about Multiprofiler is that it can be used to load the LUTs of different profiles into the INTERNAL graphics processor in the display, and that color setting will stay - even when the display is not hooked up to a computer.
The first part of this shows the typical procedure for editing a custom Picture Mode preset. The second half shows how to use this to emulate a printer profile.
Launching

Selecting the Response Improve setting helps reduce blurring that can occur in fast-moving images.
Selecting the Metamerism correction setting can improve the white point color matching when the monitor is used side-by-side with a standard color gamut monitor. This feature compensates for the way the human eye perceives colors slightly differently compared to the scientific instrument used to adjust the monitor during calibration. This difference is due to the different spectrum of light that makes up the screen image on the wide color gamut compared to that of a standard color gamut monitor.

This is a list of all printer profiles on the system. (It is also possible to use the "Add from other location" button to bring in monitor profiles and view them in the 3D LUT feature.)

The next page bring you here where you can choose a rendering intent to be used to create the LUT. Here, too, you can view your choice in a 3D LUT. You can use this to see the differences between rendering intents.

It is also possible to enlarge this 3D LUT window to get a better view of the points. (See bottom right corner.)

In order to match a printer, you need to carefully set the white of the display here so that it matches the white of your printer paper under your specific illumination.

Finally, you are able to set the brightness to further define that the brightness of the display matches that of the iluminated paper.
