New Updates For QuadToneProfiler for macOS and Windows

I have been focusing on developing native applications for my QuadToneRIP profiling tool for the past 18 months—first with the native macOS apps and now, after several months of work, a native Windows version of my digital negative profiling application.

Now both versions of my QuadToneProfiler-QuickCurve-DN tools are native standalone apps for Mac and Windows.

Both versions have the following features:

  • A flexible starter curve that can be used for a wide range of processes

  • An easy to use adjustment to change the total blocking density, including additional Yellow ink, as well as the total ink load for the whole tonal scale.

  • An advanced linearization system that uses measurement files in a variety of standard formats, including SpyderPrint tab delimited .txt files and CGATS files.

  • Charts with 21, 51, 86, 101, 128, 129, and 256 steps and will average charts with multiple samples per patch.

  • Measurement smoothing controls to even out inconsistencies with hand coated processes and measurements errors.

  • The standard output curve creates Linear lab L* densities, but the output curve control can map the final densities to a custom curve, replacing the need to add additional correction curves in Photoshop to adjust for the overall lightening effect of relatively low Dmax of some processes when mapped to a linear Lab L* scale.

There are only a few features from the macOS app that the Windows app is lacking, but will have feature parity in the next couple updates. Here are the few differences with the initial release of the Windows application

  • The Windows app supports two type of measurement files, a generic tab delisted text file with in 4 column LAB format (that has a GRAY L\* A\* B\* ) column headers and a standard tab delimited CGATS file format.

  • The Windows app doesn’t have a way to add or read notes from the quad file yet, but will in the next update.

  • The two smoothing calculations are /slightly/ different between each version, but have virtually no affect on the final quad file, but the same inputs between each version will produce slightly different results.
