FYI for those of you using this excellent tool, or need to handle the data i1Profiler spits out correctly or convert that data, here's what's new:
New features:
Join files tool:
Join two or more opened files to create a new file.
Joins files of the same color reference type: (spectral/xyY/XYZ/L*a*b*/L*C*h*), RGB, CMYK.
Select if you also join the ID and Name data fields of each file.
When joining files of the tristimulus/spectral type, you can also join their RGB and CMYK data if it was also present in each file when it was opened.
Patch view tab of opened files (standard files):
Added a set of functions to edit the patch list: Select/Deselect a Row, Column, or All. Invert selection. Swap two patches. Move selected patches before or after a patch, to the first column, or to the last column. Flip the patches of a row or column. Replace selected patches by: White, 50% Gray, Black, OSA-UCS background. Copy selected patches to the last column. Add White patches to fill the last column. Extract selected patches to a new file. Delete selected patches.
Added a target generation and analysis dialog (accessible from the ‘Re-map’ menu): Scramble a layout by selecting: the paper color, the minimum color difference between the paper and the patches on the edges, and one of three scrambling methods. The first two scrambling methods have a goal of 20 DeltaE* (CIELAB) for the color differences between adjacent patches while the third one has an adjustable goal. Analyze a layout to see its compatibility with i1Pro target measurement requirements. You can also (try to) fix the rows of a layout for improved contrast.
Display-Check: Added a checkbox, called ‘Use RGB’, to force RGB pass-through for a PatchTool file. When selected, the program uses the RGB data directly. Different workflows are possible depending on the RGB data origin, which is either found in the file or obtained from a user-selected profile:
‘Use RGB’ selected + RGB data WITHOUT profile info: This is most often the case when a file has RGB data in addition to spectral or L*a*b* data. The measured data is presented in a standard file window (NOT a Compare file). The data is computed in D50 with a Relative-Colorimetric conversion between the measured display White Point and D50 (same process as in Display-Reader when a WP is measured). This file can be COMPARED with another file if required.
‘Use RGB’ selected + RGB data WITH profile info: The measured data is presented in two files: a standard file window, as described above, AND a Compare file. The Compare file is similar to the file obtained with the ‘Use RGB’ NOT selected workflow.
‘Use RGB’ NOT selected (the old workflow): The measured data is presented in a Compare file.
RAW (i.e. non-processed) data is available in all cases.
Compare files: The ‘Cert. report’ button now appears in the ‘Stats’ tab when comparing any two IT8.7/4 files. This certification report can be used, and should be used only, for assessing conformance to G7 Colorspace Pass/Fail requirements (Web site / pdf), and for ‘IDEAlliance PROOFING CERTIFICATION & VERIFICATION PROGRAMS (Version 16)’ (Web site / pdf). For printed targets, the report tolerance options are:
Idealliance Hard Copy Proofing (V16)
G7 Sheetfed Offset Print (Colorspace P/F)
G7 Proof (Colorspace P/F)
Substrate Correction tool: Added the option to select the CIEDE2000 formula when computing the color difference between paper whites.
Extract Target from Image tool: This tool can now extract targets from 8 bit PNG images.
Open PNG image files as patch files:
Supported image format: RGB; 8 bit
Maximum image size: none. However, because each pixel becomes one patch, opening large images (64KB+ pixels) is not recommended, since success will depend on system resources.
Export Image dialog:
The PNG and BMP image export formats are now available on both Mac and Windows.
You can include an ICC profile in exported PNG and TIFF images. The profile must be defined by an external file; internal PatchTool RGB profiles are not supported.
You can add row numbers to better locate patches in exported images.
