Introduction to SpectralVision Pro

SpectralVision Pro is provided with ColorBurst to measure and save linearization targets.

A linearization file is a curve that corrects for non-linear output throughout the tonal scale. Over time (and on every different media) a printer will drift from its original state. By relinearizing you are updating an environment’s existing linearization and putting the printer back into its original state, reproducing all the conditions under which the ICC Profile was made. When you relinearize, you have made the ICC profile as accurate as the day it was made.

SpectralVisionProInstallation

SpectralVision Pro is installed as part of the ColorBurst installation. The SpectralVision Pro program can be launched directly from ColorBurst through the Linearization Options dialog. It can also be found on your hard drive in the ColorBurst\Profiling Tools & Docs\SpectralVision folder. SpectralVision Pro is also available for download on the ColorBurst web site, www.colorburstrip.com.

SpectralVision Pro is available for both the Windows and Mac OS X platforms. The SpectralVision Pro interface is identical on both platforms.

Spectrophotometerdrivers

Device drivers for X-Rite spectrophotometers are located in the ColorBurst\Profiling Tools & Docs folder. When connecting your device for the first time, use the New Hardware Found dialog to select the driver from the ColorBurst\Profiling Tools & Docs folder.

NOTE If you have already installed X-Rite software or drivers you will not need to use the drivers in the ColorBurst\Profiling Tools & Docs folder.


The SpectralVision Pro Interface

The SpectralVision Pro interface consists of a single window used to select a target and device, connect to the device, and read your patches.

SpectralVision Pro targets must first be printed through ColorBurst before they can be read by SpectralVision Pro.

IMPORTanT All linearization targets must be formatted for SpectralVision Pro. Targets that were formatted for older versions of SpectralVision will not work with SpectralVision Pro.

1. TargetChoose the linearization target that you want to measure from the Target pop-up menu. Targets are pre-loaded for all supported spectrophotometers.

The Creation Date, type and number of Patches, Target Type, and Page Count will be listed for the selected target. The target patches will also be shown in the Target Display window.

�. MeasurementdeviceThe Measurement Device pop-up menu will automatically select the spectrophotometer associated with the target you have chosen. Be sure that your Measurement Device matches your selected Target. Targets are formatted differently for various spectrophotometers and are not interchangeable.

Figure2.2.The Measurement Device pop-up menu indicates the spectrophotometer brand and model, which should match your target selection.

SerialPortIf you are connecting your device via serial port, the available serial ports will be listed here.

Connect/disconnectThe Connect button is used to establish communication between SpectralVision Pro and your device. After a successful connection, a Device Info dialog will be shown with options specific to your spectrophotometer (calibration, patch import from memory, etc.). This dialog can be accessed again later by clicking the Info button (“i”) next to your device.

After a successful device connection, the button changes to Disconnect. This can be useful if you happen to be using more than one device in SpectralVision Pro—you will need to disconnect from one device before establishing a connection to another. When you are finished using SpectralVision Pro, click Disconnect to close communication with your device or simply Quit SpectralVision Pro.

NOTE If you have used any other software applications to connect to your spectropho-tometer, you’ll need to disconnect your device in those applications before you’ll be able to connect successfully in SpectralVision Pro.

�. MeasurementStatusThis section displays how many patches have been measured against the total number of patches in the target (e.g. “84/84” ). When selected, the Show Missing Measurements checkbox will highlight any patch that has not been measured in green.


Figure2.3.The Measurement Status bar displays the number of patches that have been measured.

As patch data is measured it is visually represented on the screen in the Target Display window. You can select specific patches by clicking on them. Clicking the Info (“i”) button next to the progress bar will bring up a dialog displaying Patch Info and Measurement Info for that patch.

Patch Info includes the location of the patch on the target (Page, Row, and Column) as well as the CMYK % values of the patch in the target file (these are the values sent to the printer - not the measured values). If the patch has been measured, a Lab value of the mea-surement is also displayed.

Figure2.4.The Patch Info window can be used to get data on a specific patch.

The Measurement Info dialog (which expands when the arrow next to it is clicked) displays additional information about the actual measurement of the patch. Colorimetric data is dis-played as Lab, LCH, and XYZ values. A spectral response curve is plotted against the visual spectrum. Density values can be displayed as Status T, E, or A with a Minus Paper option, which discounts the affect of the paper on the density reading.

�. TargetdisplaywindowThe Target Display window shows a representation of the currently selected target. If the patches have not been read, the patch squares are half-filled with the color of the patch. When the patches have been read, the other half of the patch is filled with the actual reading color.


Figure2.5.The patch display before measurement, with green highlights to show missing measurements (top), and the patch display after measurement, with a red highlight to indicate the selected patch (bottom).

The Zoom magnifying glass icon at the bottom of the Target Display window allows you to zoom in and out on the target if you wish. Page information for the target is also displayed (current page/total pages) with arrows to move back and forth through multiple-page targets.

If you make a mistake in your measurements or you just want to start over, click the Clear Data button to erase all measured data.

Figure2.6.The Zoom button, page scroll, and Clear Data button appear at the bottom of the patch display window.

�. SavedataThe Save Data button is active when measurements have been completed. Clicking this button will prompt you to save a Linearization file (.lin), which can then be used in ColorBurst. This file can be saved in any location, including the desktop. However, we rec-ommended that LIN files be saved in the same place for archival purposes (e.g. ColorBurst\Lin folder).

Introduction to Linearization

How can you guarantee that today’s prints match the ones you did last week? There are many variables to consider. Over time, and on every different media, a printer will drift from its original state. Printers, paper, and inksets all have slight variances in manufacturing consistency. Altitude, age of printer, and humidity can come into play causing one printer not to match another even if they have the same model number, inkset, and paper.

The answer is linearization. A linearization file is a curve that corrects for non-linear output throughout the tonal scale, and is an integral part of each ColorBurst environment. Relinearizing a ColorBurst envi-ronment allows ColorBurst to account for these differences and adjust accordingly, ensuring consistent output from your printer over time. This puts the printer back into its original state, reproducing all the conditions under which the ICC Profile was made. When you relinearize, you have made the ICC profile as accurate as the day it was made.

TheRelinearizationProcess

Relinearizing is the process of printing a target, measuring the target with a spectropho-tometer, saving the measurements as a LIN file, and loading the LIN file in ColorBurst. ColorBurst adjusts the new LIN file values to meet the baseline values that were originally set in your ColorBurst environment. ColorBurst’s SpectralVision Pro software gives you com-plete control over the entire relinearization process.

SpectralVisionProInstallation

SpectralVision Pro is installed as part of the ColorBurst installation. The SpectralVision Pro program can be launched directly from ColorBurst through the Linearization Options dialog. It can also be found on your hard drive in the ColorBurst\Profiling Tools & Docs\SpectralVision folder.

The Relinearization Process

IMPORTanT When relinearizing a ColorBurst environment you must use a UV-filtered spectropho-tometer. Using non–UV-filtered devices will lead to undesirable results. Always print a nozzle check test prior to printing a Linearization Target.

1. PrintthelinearizationtargetthroughColorBurst.In ColorBurst, do the following:

a. Load the environment you want to relinearize.

b. Make sure your printer settings are correct and your printer is ready to print.

c. Open the Linearization Options dialog (Options menu > Linearization Options).

d. Choose the spectrophotometer you wish to perform your measurements with. This selection ensures that the target is properly formatted for your spectrophotometer.

Figure4.1.Select your spectrophotmeter and click the Print target button in the Linearization Options dialog.

Chapter�


e. Click the Print target button to send the target file to the ColorBurst Job list. If the file comes in on hold, activate the file and make sure the RIP is on to print the target.

nOTE When the linearization target is printed using the Print target button, ColorBurst will turn linearization and color management automatically for the target. This al-lows the target to print in a raw (unmanaged) state.

Figure4.2.Print a Lin target that has been formatted for your spectrophotometer. You may need to trim the target to fit your device.

nOTE Do not scale the linearization target. Always print it at 100% of the original size.

�. launchSpectralVisionPro.Open the Linearization Options dialog, go to the SpectralVision Pro tab, and click the Launch SpectralVision Pro button. You can also open the application in the ColorBurst\Profiling Tools & Docs\SpectralVision folder.

Figure4.3.Launch SpectralVision Pro to measure the Lin target.

�. Selectyourtargetandconnecttoyourdevice.a. In SpectralVision Pro, select the Lin target for your device in the Target menu.

b. The Measurement Device field will automatically select the spectrophotometer associated with the target you have chosen. If your device uses a serial connection, select the correct port in the Serial Port pop-up.

c. Click the Connect button to connect to your device.


nOTE When you click the Connect button, a Device Info dialog appears with settings specific to your device. This dialog can also be accessed clicking the Info button (“i”) next to the Measurement Device pop-up menu.

�. Measurethelintarget.Use your device to measure the Lin target. (See your device’s documentation for operation instructions.) As the values are read, the patches will be displayed in SpectralVision Pro, and the Measurement Status bar will show the measurement progress. If you encounter an error reading the patches, you can click the Clear Data button to start over.

�. Saveyourlinearizationfile.After all of the patches have been read, save the measurements as a Lin file by clicking the Save button. It is recommended to save your Lin file in the ColorBurst\Lin folder, but they can be saved to any location.

�. loadyourlinfileinColorBurst.In ColorBurst, do the following:

a. Go to Options menu > Linearization Options.

b. Click the Select a lin file button. Locate the Lin file you saved in step 5 and click the Open button. This loads the measurements from the target into ColorBurst.

c. Click OK to close the Linearization Options dialog.

Figure4.4.Use the Select a lin file button to use your new Lin file.

�. SaveyourColorBurstenvironment.In ColorBurst, you must save the environment at this point to lock in the new lineariza-tion. Use Environments > Save As to save your environment with a new file name in the ColorBurst\Env folder (or a subfolder of the Env folder). You will need a new name because you can not save over any existing ColorBurst environments. If you do not save the environ-ment, you will lose your new settings as soon as you change to a different environment.


Figure4.5.Make sure to save a new environment with your new lin file loaded to lock in the relinearization.

Linearization Troubleshooting

Sometimes a printer, ink, and media combination can not be relinearized. If the differences between the printer that made the original linearization and the printer that is being relinearized are significant, ColorBurst will report a Linearization Error. This will happen when the measurements from one or more inks come in lower than the Baseline values. Often this error can be overcome by simply increasing the ink channel that failed (a failure will be reported if an ink channel is too low).

If measurements are below the baseline values established in the orginial environment but are still within an acceptable range, a Linearization Warning dialog will appear after loading a new lin file. It is recommended that you try to eliminate the warning.

1. determinewhichinksarecausingtheerror.When you open a Lin file with measurements that are lower than the established Baselines, an Error message will appear. The dialog will report any ink(s) that failed to reach the Desired baseline number by displaying the Actual value in bold.

Figure7.1.An Error dialog will appear when a lin file is opened if the measurements are lower than the established baselines in the original environment. A Warning dialog indicates values are low but still within an acceptable range.


�. Verifyyoursettings.a. Check and make sure the paper in your printer matches the environment you are

relinearizing.

b. Perform a nozzle check test (at the front panel of your printer, check your manual for instructions) and do head cleanings if necessary until all nozzles are firing completely. If any nozzles were clogged you will need to repeat the relinearization process.

c. Make sure that you are using a spectrophotometer with a UV filter. All lineariza-tions provided with ColorBurst environments were created with a UV filtered spectrophotometer.

�. adjusttheMax.Inkvaluesifnecessary.If you have verified all of the above and the error continues then you will need to increase the Max. Ink percentage for any ink that is too light. Go to Options > Color Adjustments and increase Max. Ink % values by 2 for each ink that was listed in the Error or Warning window as too light. Click OK to close the dialog and store the new value(s). Save your environment and repeat the relinearization process.

Figure7.2.Increasing the Max. Ink values by 2% can sometimes help increase low measurements in a Lin file.

�. linearizationErrorwhenMax.Inkvaluesareat100%:If your Max. Ink settings are at 100% and you are still getting linearization error mes-sages, the current printer/paper/ink combination can not be relinearized to the Baseline values saved in the original environment. Choose a different environment or contact Epson Technical Support for assistance. Select Epson Support under the Help menu for Epson Support contact information.
