ScreenPro Release Notes

V3.2.2 – November 2021

  • Fixed a defect where sometimes linearization data was incorrectly being preferred over calibration data when calibrationMethod = "Mixed" and both types of data were present.

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.

V3.1.0 – May 2021

  • Added NozzleOut compensation functionality.
  • Allow negative calibration offset to be specified.
  • Replaced customer number with license and password for relevant PrintFlat and ScreenPro APIs.
  • Added more checks on the integrity of screen's configurations ("config.txt") and remove implicit order dependencies.
  • Added new API to allow users to retrieve variants of their LE licenses.

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 subscription generation and calibration installation has been moved from ScreenPro library to a new PrintFlat library. Please refer to ScreenPro.h and PrintFlat.h.
  • Added ScreenProValidateScreen function that can be called before screening to ensure settings and calibrations are valid.

V2.7.0 – November 2020

  • Correct handling of photometric interpretation for TIFF format, so that there is no longer a requirement for calibrations to use "Min is White".

V2.6.0 – October 2020

  • Added support for reading in custom curves in a binary format.

V2.5.0 – August 2020

  • Added support for calibration alignment and offset. To implement this, the ScreenProLayout structure used by the ScreenProScreen and ScreenProScaleAndScreen API functions has been updated to include all calibration parameters within a new CalibrationOption struct; this is a breaking change for API users that explicitly set each member of ScreenProLayout.

V2.4.7 – August 2020

  • Fixed an issue where ink limiting was not working for 1 drop screens.

V2.4.6 – July 2020

  • Internal changes only

V2.0.0 – June 2018

ScreenPro Version 2.0 introduces the following new features and functionality:

  • 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.
  • Inputs/outputs
  • Alphanumerical Colorant names are now supported.
  • Mirror/Pearl now supports 256 input channels.
  • New PassThrough screening method allows the user to test pre-screened content from the application and the SDK.
  • Specified output bpp can now be changed for TIFF output (SDK)

  • Mirror/Pearl configuration file updated to new format: Tom's Obvious, Minimal Language (TOML) to improve readability and extendibility.

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.
  • 16 bits per pixel input support for ScreenPro DLL.

  • 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.)

  • In some circumstances color strategies with a space in their name might not be found if referenced from a JDF.

V1.6.0 – November 2017

  • Users can now nominate which page(s) to use as a source for thumbnail generation.
