Prinergy Evo software has been updated from version 6.1.3 (released June 2015) to version 8.1 (released spring 2017). In the two years between the Prinergy Evo releases, ColorFlow software has been updated from version 2.1.2 to 7.5.0 to 7.5.1 to 8.0.0 to 8.0.1 to 8.0.2.

These release notes document the multi-version changes in the ColorFlow software that you will encounter when you use ColorFlow software in the Prinergy Evo 8.1 software. Unless otherwise noted, these changes were made in version 7.5.0.

New Features and Enhancements

Version number upgrade

The ColorFlow version number is now aligned with Prinergy Evo version numbering.

Multiple output versions

In the previous version of ColorFlow, you could create only one conversion for an SCO. If you wanted to have multiple output conversions for an SCO, you had to create multiple color setups. You can now create multiple versions of the conversion for an SCO and use the same device condition as the PCO. You can give each output version a name and select one version as the default. The default version will be used for Evo output. You can also add, delete, redefine, and adjust output versions.

Multiple input versions

In the previous version of ColorFlow, you could only create one conversion definition for a color input except for optional separate image and graphic conversions. If you wanted to have multiple color input conversions for a color setup, you had to create multiple color setups. You can now create multiple versions of the conversion for a color input. You can give each input version a name and select one version as the default. The default version will be used for Evo Refine.

Measurements

Measurement import

In the Measurements tab, the Import button now uses the native Finder or Explorer browser, but no longer supports multiple file import. You can now import multiple measurement files by clicking the newly added Import Multiple button.

Measure Tint Ramp chart

You can now launch Tint Ramp chart measurement directly from the Charts tab of the Measurements dialog.

Estimate response from current device condition 

You can now estimate color response from the currently active response of a device. This allows you to modify the white point or the gain of the active measurement.

Colorimetric Response Estimation for spot inks 


When you estimate the response of a device condition with a white point change, spot inks measured in the original device condition are included in the estimated response.

Selectable spot mode measurement for i1Pro hand scan

Previously, when measuring a P2P chart with the i1Pro hand-held device in scan mode, you were returned to spot mode after a measurement failed twice. Now (version 8.0.1), if the measurement fails, in the Measurement Error dialog box that appears, you can either retry in scan mode by clicking Retry or return to spot mode by clicking Spot Mode.

Measurement condition is checked for tint ramp measurements

To ensure consistency, measurement condition (M0, M1 or M2) is now checked when you re-measure a Tint Ramp chart to add another ink ramp or average measurements.

Measurement condition is checked for estimate substrate measurements

To ensure consistency, measurement condition is now checked when you measure the substrate for a response estimate with a substrate change. 

iSis Measurement Condition control  

You can now measure with iSis models using M0 and M2 illumination conditions.

Support for iSis2 M0 and M2 measurement

ColorFlow 8.0.1 supports iSis2 M0 and M2 (but not M1) measurement.  

Support i1iO M1 and M2 measurements in scan mode

ColorFlow now (version 8.0.1) supports i1iO M1 and M2 measurements in scan mode, which considerably reduces the time it takes to measure a characterization chart using these measurement conditions.
Note: You can’t measure the built-in Minimum Full CMYK i1iO chart, or charts generated from a previous version of ColorFlow, using M1 and M2 scan modes.

New built-in charts 


The following new charts have been added in the Charts panel:

New P2P chart for gray balance curve generation

(Version 8.0.1) You can now use a P2P chart to generate gray balance curves and obtain G7 certification in both the Workflow Edition and the Pro Workflow Edition.

Measure P2P25 chart with i1Pro hand scan

You can now (version 8.0.1) measure a P2P25 chart with an i1Pro and i1Pro2 by hand scanning. Measurement methods includes:

  • Single scan for M0 (i1Pro2 and i1Pro without UV cut filter)
  • Single scan for M2 (i1Pro with UV cut filter)
  • Dual scan for M1 and M2 (i1Pro2)

To measure with the i1Pro(2), connect it to your computer and choose the P2P25-i1iO or i1iPro chart. You can then measure the chart by following the measurement wizard.

In the wizard, you are provided with different hand scanning instructions for i1Pro2 and i1Pro:

  • Place the sheet on a white background for the i1Pro
  • Place the sheet on the provide backup board for the i1Pro2

i1 Pro2 UV-controlled measurement

ColorFlow now supports measurement condition M1 and M2 selections for i1 Pro2 for hand-scan, and patch measurements.

Measurement wizard improvements

Some text and button layouts have been changed to reduce confusion in the measurement wizard:

  • Identify Next Sheet dialog title has been changed to "Measure More Sheets?" and buttons are renamed for clarity
  • Sequence of buttons in wizard dialogs for MacOS has been corrected

Measurement chart wizard improvements

In version 8.0.1:

  • The title and messages in the Load Page state dialog have been modified to improve clarity.

  • Row identification numbers are now displayed.
  • You can reverse your actions by clicking the Back button.

Changes in the Device Measurements panel 

Some changes have been made to the Measurements tab for device characterization:

  • The Title now includes the name of the device
  • The Chart ID is now combined into response origin
  • Characterized spot inks and their response type are now listed
  • The Icon for Estimated is added to response origin
  • Command buttons for inactive measurements are not available until you select a table row

CMYK References

Integrate ISO 12647-2:2013 ISO TVI Curves

The following new ISO specifications have been added as built-in CMYK Reference device conditions:

  • ISO Curve A (2013)
  • ISO Curve B (2013)
  • ISO Curve C (2013)
  • ISO Curve D (2013)
  • ISO Curve E (2013)
  • ISO Curve A+B (2013)
  • ISO Curve B+C (2013)
  • ISO Curve C+D (2013)
  • ISO Curve D+E (2013)

To distinguish the newly added specifications from the existing ISO specifications, the names of the existing ISO specifications have been modified with the suffix "(2004)".

Include FOGRA 48, 49 and 50 CMYK Reference device conditions

The following recently published FOGRA print specifications have been added as built-in CMYK Reference device conditions:

  • FOGRA 48 - Heatset Web Newsprint, Improved
  • FOGRA 49 - Matte laminated FOGRA 39
  • FOGRA 50 - Gloss laminated FOGRA 39

Plate curves

New Plate Curves tab

A new Plate Curves tab has been added to the main dashboard for managing plate curves. This replaces the View > Plate Setups menu item in the previous version of ColorFlow. 

Print curves

New Print Curves tab

A new Print Curves tab has been added to the main dashboard for managing print calibration and transfer curves.

Create print transfer curves 

You can now create a transfer curve with CMYK and spot curve channels. These may be selected as device curve presets or selected in Prinergy for print calibration.

Create print calibration curves 

You can now create a  print calibration curve directly by selecting a measured device condition response and a calibration target. This is an alternative to defining a reference PCO and curve-controlled SCO in a color setup.

Hide Flexographic Press curves

(Version 8.0.1) You can now hide Flexographic press transfer curves by clearing the Show Flexographic Press Curves check box in the Transfer Curves section of the Print Curves tab.

Reports

Changes in Print Comparison reports

Some changes have been made to the Print Comparison reports:

  • Previously, the Section 3.2 'Tonal Value Increase, curve removed' appeared only in the Print Characterization reports. This section has been added to the Print Comparison reports.
  • Max dE patch has been included into table 2.2.1.

Report modifications

(Version 8.0.1)The tint values in Figure 4.2.1, Figure 4.3.1, and Figure 4.4 of the Print Comparison report have been modified for measurements obtained from a P2P25 chart.

Show multiple ISO gray measurement points

The Print Characterization reports now show the cast of each measured ISO gray balance patch. The Print Comparison reports now show the average value.

Axes of grey balance graph in reports are scaled

Axes of grey balance graphs in the Comparison and Characterization reports are now automatically scaled for measurements with small cast errors. This makes the graphs easier to read when the cast magnitudes are small.

Show ISO CMY Neutral Tint values in Comparison report

ISO publishes CMY Neutral Tints at nominal cyan values of 0%, 2%, 4%, 6%, 8%, 10%, 15%, 20%, …, 85%, 90%, 95%, 98%, 100%. In the previous version of ColorFlow, the Print Comparison report only showed 5% increments of cyan. The Print Comparison report now shows all the nominal cyan values.

Flexographic Mindot in 3-color gray balance plots of Comparison Reports

For flexographic device conditions with a Mindot, the minimum ISO CMY neutral tint value has been added to the Print Comparison reports.

Print comparison report shows target response for spot inks

The Print Comparison report definition now allows selection of a spot ink target device condition if spot inks have been measured. 

Other changes in reports

Some other changes in reports include the following:

  • "User Comments" has been changed to "Subtitle" in reports
  • The measured device is now identified in reports
  • You can now hide the explanatory text to produce a compact report
  • Reports are now generated in the background, releasing the ColorFlow user interface for other tasks
  • Spider plots are now included in the Print Characterization and Comparison reports for spot inks whose colorimetric response is measured

Device curves

Verify pooled device response

You are now prompted with a warning message if the response of a device indicates it may not be compatible for pooling.

Changes in Device Curve Definition and Measurement workflow

Some extensions have been made to the Device Curve Definition and Measurement workflow. For Prinergy Connect and Powerpack integration, you can now launch measurement before defining device curves. When the measurement is activated, the selected characterization curve becomes the device curve definition. You can also use the current workflow. For Prinergy Evo integration, always define Device Curves first; see below. <Put in User Guide>

Other changes are:

  • The Default Device Curves button and associated Definition dialog boxes have been removed from curved device conditions.
    When you define properties for a new curved device condition, the Device Curves and Measurements icons of all devices both become orange, indicating you can click either button next. For Prinergy Evo integration, always click Device Curves first.
  • When you define device curves for one device, the definition becomes the default for other pooled devices.
  • The Use Current State for Approved Snapshot option has been removed from the device condition level. It's now an independent option for each device, and appears in both the Edit (Adjustments) and Definition dialogs for device curves.

Device conditions

New Device Conditions tab

A new Device Conditions tab has been added to the main dashboard for managing device conditions. This replaces the View > Device Conditions menu item in the previous version of ColorFlow. You can create, view, and modify device conditions in the Device Conditions tab. You can also create, select, and modify device conditions in the Color Setups and Print Curves tabs where the device conditions are being used.

Promoted device appears at the top of device pool

In the previous version of ColorFlow, curve-controlled devices appeared in the device condition pool in the order they were added. Now, the promoted device always appears at the top of the pool.

Verification

You can now check if the response of a print calibration curve, an SCO, or a PCO matches the target in a Verification report

Verification reports include comparison of predicted response to Target (PCO report) or PCO (SCO report). You can use Verification reports to check if the color response of a PCO or SCO matches the target. You can also use Verification reports to check if the color response of the calibrated output for a print calibration curve matches the target.

Distinguish gray balance response from full color response

(Version 8.0.1) Process inks response types have been updated to distinguish gray balance response from the full color response:

  • If a process inks response is defined by a spectral measurement of a P2P25 chart, the response type is "Gray Balance and Tonal".
  • If a process inks response is defined by an imported CIELAB-only measurement of a P2P25 chart, the response type is "Gray Balance only".
  • The "Color only" response type has been renamed as "Full Color only".
  • The "Color and Tonal " response type has been renamed as "Full Color and Tonal".

Profile Adjustment

A new Show curve changes only option has been added to the Profile Input Curves and Profile Output Curves view/edit dialog box. If this option is selected, the curve graphs and the curve values of the selected color channel only show adjustments made to the curves.

Support PDF/X Output Intent

(Version 8.0.1) ColorFlow now supports a new device type called PDF/X Output Intent. It is similar to CMYK Reference, but is always characterized by an ICC device profile. ColorFlow provides built-in PDF/X Output Intent device conditions containing device profiles registered at http://www.color.org. You can also create custom PDF/X Output Intent device conditions using imported profiles.

Color setups

New DeviceLink Method

You can now generate DeviceLinks by using the new Profile Pair Linking method. The DeviceLink is generated by direct evaluation of source and destination profile tags, providing the same black generation as the destination profile. The method applies to RGB and CMYK color inputs, and non-curved SCOs.

Ink Optimizing Solution

New Ink Optimizing Solution DeviceLink method for RGB color input conversion

If you have the license for Ink Optimizing Solution, you can now select the Ink Optimizing Solution method when generating DeviceLink profile for an RGB color input conversion. 

Operating system support updates

Mac OS Support Updates

You can run ColorFlow 8.0.1 on macOS Sierra, OS X El Capitan, and Mac OS Yosemite. 

Windows OS Support Updates

You can run ColorFlow 8.0.1 on Microsoft Windows 8.1, 10, or Microsoft Windows Server 2008 or 2012.

Ticket Number

Descriptions

CLRFLW-5635

In the previous version of ColorFlow, it took a long time to delete large snapshots and sometimes the deletion failed. Now you can capture or delete large snapshots quickly.

CLRFLW-5554

When you exit ColorFlow, ColorFlow needs to remove unwanted items from the ColorStore before it is fully closed. The process may take a few seconds or minutes. Previously, ColorFlow displayed an unresponsive UI frame in the screen while updating the ColorStore. Now, a message appears instead of the UI frame, warning you not to manually force ColorFlow to quit.

CLRFLW-5537

In the previous version of ColorFlow, in the Simulation Definition dialog box, if you selected a Target and then selected the Curves Method as Manual Adjustments Only, the Target you selected became None. This issue has been fixed. This allows you to define the Simulation with Manual Adjustments Only curves and a DeviceLink. <Please add this sentence to the ColorFlow 7.5.0 release notes.>

CLRFLW-5526

In the previous version of ColorFlow, you were not able to measure a tinted background chart with i1Pro for M1 and M2. This issue has been fixed.

CLRFLW-5204

In the previous version of ColorFlow, the default settings for Ink Optimizing Input DeviceLink were incorrect. This issue has been fixed.

CLRFLW-5303

In the previous version of ColorFlow, figures 3.1.1 and 3.1.2 in reports showed the wrong estimated device tonal response. This issue has been fixed.

CLRFLW-5220

In the previous version of ColorFlow, tonal response was only reported for curve-controlled devices. Tonal response can now be reported for CMYK Reference device conditions.

CLRFLW-5197

In the previous version of ColorFlow, the wizard buttons for the measurement process in ColorFlow for Mac didn't have the same sequence as in ColorFlow for Windows. This issue has been fixed.
