Re: Maximum GCR settings to save ink
Hi Walter,
For target which allows to estimate the TAC, you can download one developped by TGLC inc. at the following URL:

Once printed, you can see the optimal Ink coverage you can use for specific paper, etc.
This is the first part of ink saving (TAC). The other is using GCR (Gray Component Replacement). This can be set in ICC profiling software OR when you create an ICC DeviceLink profile (PerfX Device Link™). This will allows to remove CMY gray components and replace it with Black ink. This way, you save CMY inks, but use more Black ink.
ICC DeviceLink profile can be used in most prepress workflow, compatible with ICC DeviceLink profile. No need external server to do so.
To do it properly, many tools are needed:
— Gray balance curve calculation software (PerfX Press Curves™)
— ICC profile creation software (PerfX Color Management Pro™)
— ICC DeviceLink creation software with ink saving option (PerfX Device Link Pro™)
— Compatible prepress workflow allowing to use ICC DeviceLink profile for CMYK to CMYK conversions.
Don’t forget: QC and consistency at the print press!
Hop this help!
