we currently use a ColorQuest XE, our purified water results are close to 0.0 (Spec +/- 0.10) We are switching to a UtlraScan Vis and our water results range from -0.12 to -0.08, would you know what could be causing this discrepancy?

A discrepancy in purified water results between the HunterLab UltraScan VIS and the ColorQuest XE could be caused by differences in instrument-specific optimized values used in calculations, such as P, Q, and C in the WI Ganz equation. These values are tailored for each instrument. Additionally, differences in UV filter calibration procedures or the condition of the fluorescent standard used for calibration (e.g., faded spot 3 vs. spot 4) could also contribute to variations in results.

This manual is comprehensive in that it provides information concerning your color measurement instrument and computer hardware (including installation, use, maintenance, and troubleshooting) as well as instructions for use of the EasyMatch QC software. Thus, every component of your color measurement system is covered.
The basic features of EasyMatch QC are discussed in the rest of this chapter, lessons helping you learn to use those features are given in Chapter 2, and the various software menus are explained in chapters 3 through 10.
If you wanted to transfer a job to another computer or another user who also has EasyMatch QC, the job file (with a .JSD file extension) would contain all the information needed to examine and/or reproduce your results.

A template is meant to be used as a starting point in creating a new job when the same views are used for many jobs. You can then “fill” the template with measurements and configuration settings. Several application-specific templates are installed with EasyMatch QC. These templates provide a starting point for new jobs.
EasyMatch QC User’s Manual Version 2.1 Templates contain no standards or samples. The measurements would be added to the job as they are made. The screen configuration and options for each data view comprise the template and will be part of any job created using the template.

(Chapter 3) for information on saving data to the database and recalling data from the database and the Options Menu chapter (Chapter 7) for information on configuring the database type and location. Once the database is configured, its name is displayed on the EasyMatch QC title bar after the job name.
Toolbar Buttons The toolbar at the top of the screen provides quick access to many functions in EasyMatch QC via its buttons. All functions incorporated into the toolbar may also be accessed through the drop-down menus.
This chapter provides lessons that walk you step-by-step through some common procedures in EasyMatch QC. These lessons have you configure screens and use sample data which may not apply to your situation. However, if you work through the lessons you should end up with a good feel for how the software operates and then you can substitute your own samples and displays for the examples.
EasyMatch QC User’s Manual Version 2.1 Lesson 1: Setting Up a Job Template Suppose you wish to configure a job template called “Lesson 1” to use for jobs in which you display your measurement data. The information you require is listed below.

Choose Application Preferences from the Options menu. The Application Preferences screen appears. 39. On the Startup Defaults tab, Select Lesson 1 for the Default Template and click OK.
After standardization, we will confirm a reading of the white calibration tile. Your instrument should already be attached to the computer and installed in EasyMatch QC before performing this lesson. Instructions for standardization in transmittance are provided in Lesson 3.
Page 66
EasyMatch QC User’s Manual Version 2.1 5. Center the black glass at the measurement port with the shiny side toward the port. For a sphere instrument, cover the reflectance port with the light trap. Click Next to continue. 6. The instrument will read the glass or trap and set the zero. When it is finished, the following prompt will appear.
Page 67
EasyMatch QC User’s Manual Version 2.1 9. Click Finish to complete the standardization process and OK to exit the Modes screen. You will see the standardization mode update on the right side of the status bar if you chose to view the status bar.
LabScan XE, MiniScan XE Plus, or MiniScan EZ, do not attempt this lesson. Your instrument should already be attached to the computer and installed in EasyMatch QC before performing this lesson. Most transmission measurements are made using the TTRAN (total transmittance) mode. The steps required for performing this type of measurement are described below.
Page 69
EasyMatch QC User’s Manual Version 2.1 5. Remove the black card from the transmission compartment. If you will be measuring a film or other clear solid sample, simply click Next to continue the standardization process. If you will be measuring a liquid, place a clear liquid (distilled water for water-based samples, toluene or benzene for resins, or mineral oil for oils) in a cell of the desired size and center the clear portion of the cell over the transmission port (sphere) in the transmission compartment.
The offset value may be positive or negative and is automatically calculated by EasyMatch QC. When performing an additive hitch, the hitch standard should be very close in color to the samples you wish to measure using the hitch. For example, a reddish-orange standard should be used when measuring tomato products.
Page 71
Color Data Table for each parameter (such as L, a, and b) is the measured value times the ratio value determined by the hitch standard. The ratio value is automatically calculated by EasyMatch QC. The ratio hitch is slightly more robust than the additive hitch for measuring samples of varying colors.
Page 72
EasyMatch QC User’s Manual Version 2.1 Note: Geometric differences between instruments cause differences in measured values, as can differences in sample preparation. Hitch standardization is recommended for use only among instruments with the same geometry and using a set procedure for sample preparation.
The calendar starts out with today’s date marked. Since we wish to delete all samples that are more than two weeks old, the starting date can be somewhat arbitrary. Choose January 1, 2004, which is a date before EasyMatch QC was released. 2-18...
Page 74
EasyMatch QC User’s Manual Version 2.1 6. Click the date drop-down in the “To” area to obtain a calendar on which you may select the ending date. As before, today’s date will be shown initially. Since we want to delete samples read two or more weeks ago, simply click on the date of two weeks ago.
Page 75
EasyMatch QC User’s Manual Version 2.1 12. At this point you can examine the samples located and change your mind if you wish to keep any of them. You can click any of the column headers to sort the list on that column. Click (check) the box next to each sample you wish to delete.

APPENDIX A Measurement Values Color values calculated using EasyMatch QC are relative to the absolute value of a perfect reflecting diffuser as measured under the same geometric conditions, according to the January 1, 1969 recommendation of the International Commission on Illumination, CIE. These values are traceable to measurements made at the National Institute of Standards and Technology.
EasyMatch QC User’s Manual Version 2.1 Opponent-Color Scales (Hunter Lab, CIE 1976 L*a*b*, and CIELCh) The opponent-color scales give measurements of color in units of approximate visual uniformity throughout the color solid. Thus, in the Hunter scale, L measures lightness and varies from 100 for perfect white to zero for black, approximately as the eye would evaluate it.

Do you have a question about the EasyMatch QC and is the answer not in the manual?
Questions and answers
we currently use a ColorQuest XE, our purified water results are close to 0.0 (Spec +/- 0.10) We are switching to a UtlraScan Vis and our water results range from -0.12 to -0.08, would you know what could be causing this discrepancy?
A discrepancy in purified water results between the HunterLab UltraScan VIS and the ColorQuest XE could be caused by differences in instrument-specific optimized values used in calculations, such as P, Q, and C in the WI Ganz equation. These values are tailored for each instrument. Additionally, differences in UV filter calibration procedures or the condition of the fluorescent standard used for calibration (e.g., faded spot 3 vs. spot 4) could also contribute to variations in results.
