TurboPrint & PrintFab

Ink saturation limit not working for HP designjet 10ps,
when printing the test strip ink saturation limit is ineffective all patches print
identically and a bit heavy, this does not change when restricted to 150 or any other setting.
The Hp printer has a built in densitometer and can self calibrate but these option are not exploited by printfab is this possible to change?
Is it possible to use HP paper profiles with printfab and if so were do they go?
Is it possible to use HP printer self-generated calibrations in printfab and if so were do they go?I presume import colour profile command but not sure if those profiles would be usable by printfab.
Any advice on settings to use in Aperture when printing from printfab?

Hello,

thank you for your feedback!

The densiometer of the 10ps is not enabled in PrintFab as automatic calibration didn't work reliably with our test printer. I will email you instructions on how to enable calibration - but this is not officially supported.

It doesn't make sense to use HP's paper profiles because these ICC profiles have 4 channels (CMYK) and the conversion from cyan/magenta -> dark / light cyan/magenta is not the same in HP's driver and PrintFab.

In the Aperture print dialog, set "ColorSync Profile" to the same profile that is chosen in the OS X print dialog, section "PrintFab Settings", tab "Color", which is by default sRGB. "Black Point Compensation" can be enabled.
"Gamma" is by default set to "1.0" and can be increased a bit to compensate for dark prints - see e.g. http://docs.info.apple.com/article.html?artnum=302821

The "Gamma" setting can be used to compensate for another area in which computer displays and prints differ. Because computer displays are illuminated, images displayed on computers will tend to look more luminous than when printed. Increasing the Gamma from the default of 1.0 can compensate for this. Usually, a setting 1.1 to 1.2 is adequate.
