Harlequin Core v13.2r1 Release Notes

This page applies to Harlequin v13.2r1 and later


Harlequin Release Notes are now published directly to our website.

Harlequin Core v13.2r1 is a minor release since 13.2r0. This release consolidates work of v13.2r0 and v13.1r0.

Where performance enhancements indicate % values or time improvements, they are sometimes specific to job types and configuration; they are not cumulative.

Alerts and guidance

This release is of Harlequin Core SDK only; HMR was not built or tested.

Harlequin Core v13.2r1 change details

Jira StorySupport call(s)Summary



Defining modular screens for unrendered colorants may crash the RIP.

A workaround was provided for this issue; this Story is for the permanent fix.

HQN-383828#3940, #3968

Page Offsets Are Wrong When Using Scalable RIP and HVD or tiling



Bad output, (missing objects) with HVD for jobs with XRef object or GGSL_Opaque tags. 

Previously noted as a known issue, this possible bad output with HVD has been resolved.


Implement element cache purging for iHVD

This enhancement avoids the HVD cache becoming full, which could cause a VM error.

Micro-optimisations to backdrop table interface

Performance enhancement


Fix for Scalable RIP with multiple jobs does not send STOPPED event when farm rip max restart occurs

"Gray" Separation Loses Content

Fixes 1a. The missing content in the customer job


PDF Stack size limit exceeded

In this change We have doubled the PDF stack size so that unwieldy PDFs no longer trigger stack overflows.

Known issues

HQN-384823 - GUI hangs shortly after launch on RHEL 7.9. On Redhat 7.9 (not seen other versions or other Linux distributions). The installer for the Harlequin Core SDK Core can hang and the file  .properties  needs to go alongside the installer .bin file, and will need to set:
