GMG OpenColor DotProof jobs without CMY and with control strip

The processing of 1-bit files with an MXD profile, without CMY separations, and with a control strip led to an error.

Initialization error


GMG ColorProof GO connection

A working GMG ColorProof GO sometimes could not reach the GMG ColorProof system anymore after a few hours . All actions performed in the browser, for example the commands to pause a job, to change media, or to calibrate, were not communicated back to GMG ColorProof until a restart.

Gradation curves and spot colors in MXD jobs

The gradation curve was applied to a spot color only if the job was printed without the CMYK part of the MXD file.


Automatic Environment Backup Scheduler

The automatic environment backup was not performed at the right time defined in the scheduler. For example: The first two days, the backup started at 10:15 am, the next two days at 10:16 am, the following days at 10:17, and so on.


ProofControl Standard for MX4 files

For some MX4 files, no GMG ProofControl standard could be generated by using the functionality under Database > Proofing Conditions > open Custom Proof Standard > Proof Verification tabbed page > Generate from Proof Standard > From Contone MX4. In GMG ProfileEditor, however, this reference could be generated for the same target values.


GMG ProofControl Inline label format

The label on some jobs was wrongly printed, some rows overlapped.
