QuadToneProfiler-QuickCurve-DN Release Notes

Version 1.4

July 31, 2019

This is an update with new features and bug fixes and Apple Gatekeeper app notarization for security features in future releases of macOS.

New Features

  • Added starter curve for Lodima Grade 2 gelatin silver chloride contact printing paper using Fixxons or Pictorico transparency film
  • Added starter curve for Ilford MultiGrade Classic gelatin silver fiber-based paper using Pictorico Gloss White Film
  • Smoothing is now done on more points that result in more accurate and smoother linearized curves
  • Behind the scenes speed impovements

Bug Fixes

  • Fixed a problem with quad file and process notes not loading or saving correctly in the linearization module

Known Issues

  • Averaging multiple samples from 51-step targets does not work correctly.
    • Use QTR DataTool to average multiple measurements from a 51-step target until a fix is in place.
  • The in-app updates disabled due to the new Apple security settings. I am looking for an alternative, but updates will need to be done by downloading the new version manually. I will send an email notification for future updates until an in-app fix is in place.
  • Crash reporting has been disabled until a future update due to the same security settings issue. Please email problems directly to support@quadtoneprofiler.com
