V3.2.1 – September 2021
- Fixed a defect where a nozzle mismatch is incorrectly reported when performing NozzleOut compensation using a screen with linearizations without calibrations (
calibrationMethod = "Table").
V3.2.0 – July 2021
- Added support for non-zero offset when using Center justification for PrintFlat calibrations.
- Added support for offsets and justifications with NozzleOut compensation.

V3.0.0 – February 2021
- A new licensing policy was implemented. Unless you are using LDK licensing, you will require a new license string. Please contact your technical representative if you did not receive one.

- PrintFlat functionality now available for Mirror/Pearl.
- Cross Web Calibration to correct for banding or density non-uniformity.
- Web calibrations can now be applied to Screen sets.
- Performance improvements
- For Mirror/Pearl in ScreenPro Core Technology.
- For Chameleon Screens in the ScreenPro application.
- Licensing option to be able to screen with up to 16 instances in the ScreenPro application.
- Quality improvements
- 16 Bits Per Pixel (bpp) input support in Desktop and Command line application.
- Alphanumerical Colorant names are now supported.
- Mirror/Pearl now supports 256 input channels.

V1.8.0 – April 2018
- Extra ink limiting and screen quality improvements for Mirror and Pearl.
- Support for 16-screen levels in Mirror and Pearl.

- Custom routines can be used when reading screen tile data (potentially allowing diskless operation).
See the ScreenProRegisterIOHandler(…).
- For the Mirror, Pearl, and Chameleon screen types it is now possible to optionally specify an X and a Y offset respectively. Both are integer values and default to zero. This is useful when screening a large image in separate bands and screening each band separately, so that the X and Y offsets for each tile correspond to the X and Y position respectively of the top-left hand corner of the tile in the original image.
- The Windows command line application now accepts optional -X and -Y arguments for specifying the X and Y offset values respectively.
- The Linux command line application also accepts -X and -Y arguments.
- The maximum number of colorants is now limited to 16.
- Processing TIFF and PDF files concurrently would occasionally fail due to file locking issues.
(This solution has necessitated a reduction in logged clrip process output.)
