1. Operativeness of the software

The software works on each Apple Macintosh or PC. Simply two USB ports are

required; one for the USB stick and a second for the measuring device. It is

advisable to run the USB stick and the measuring device over a USB hub. In this

case only one USB port on the computer is necessary.

2. Software Installation

The software can be started directly from the USB stick or be copied to the

computer. The software can be installed in such a way on several computers. The

USB stick must however be present always at the computer, with which the

software would like to be used.

If the software is copied on the computer, a folder should be created and all

three files (changes.txt, DSCSUsb.bundle, UPPCT.app) should be copied in this

folder.

Afterwards the software must be activated under the menu «Registration».

Therefore the *.lic file must be loaded from the USB stick.

3. Measuring Devices

Ugra carried out all its measurements with a i1 Pro of X-Rite. As further

measuring devices the Datacolor 1005 and the X-Rite Pulse can be used.

3.1. Recommendation for the connection of measuring devices

It is recommended to connect the measuring device to a powered USB hub, which

will supply sufficient power to the measuring device. If the measuring device is

connected directly to the computer, it should at least be connected to the power

supply.

4. Start-up of the software

1. Connect the USB stick to the computer

2. Double-click the software on the USB stick (UPPCT.app)

3. Register the software

- select the option «load» under the menu «Registration» and select the *.lic

file from the USB stick.

4. All functions of the software are now activated

5. Use of other Control Wedges

If you would like to measure another control wedge, which is missing in UPPCT

you can add this wedge in the CGATS 17 mode (see chapter 8.) to the following

folder:

Mac:

User/Documents/UPPCT/Wedges

PC:

User/My documents/UPPCT/Wedges

The introduced wedge can be selected on the first page of UPPCT under «other

testcharts».

6. Use of a House Standard

If you would like to use a different standard than the ones already installed in

UPPCT, you must print an ECI-2002 test chart of the used house standard and add

the measuring file in CGATS 17 mode (see chapter 8.) in the following folder:

Mac:

User/Documents/UPPCT/Reference Wedges

PC:

User/My documents/UPPCT/Reference Wedges

The new standard can now be loaded as new reference in the menu point

«Evaluation».

7. Import of measuring data from other measuring systems

UPPCT has an import function, with which measuring data from other measuring

systems can be imported and assessed with UPPCT methods.

The measuring data must be in CGATS-17 mode (see chapter 8.). The X-Rite

measuring tool and other measuring systems provide such files directly.

The import function can be found in the menu bar.

9. Ugra score

The Ugra score is a quality number, which is calculated out of all measuring

values. For a proof all measurements, which are lower as ∆E of 2 are counted.

The found number is put in comparison to all measured values. For printing the

Ugra score is calculated with a ∆E value of 3.3

An Ugra score higher as 93 leads to an accurate proof – print match. An Ugra

score between 87 and 93 leads to an acceptable proof – print match. An Ugra

score lower as 87 leads to a bad proof – print match.

The Ugra score leads to proofs, which are more precise as described in ISO 12647-

7. The ISO 12647-7 tolerances are to big to get an accurate proof – print match.

This is easily achievable with modern proofing equipment.
