Calibrator: PMM Quality Settings

What

In the bottom right section of a PMM there is an option to select the quality. [Calibrator -> select Mode -> see bottom of Details window].  This quality does not directly relate to the quality of the calibration but to the quality of rendering that the RIP should apply when using this PMM.

There are 3 settings available:

Normal(Default)

The RIP will render at the resolution of the defined print mode. If the print mode defines 600×1200 DPI then the resolution for rendering (contone) is 600 (the lower of the 2). The output and screening are done at the resolution of the printer, so 600×1200. Because the rendered data is 16-bit data there is loads of extra data to feed the screening which is usually on 1 or 2 bits.

Draft

The RIP will render at half the resolution and thus be 2 to 3 times faster than normal. As the output and screening is done at the fulll resolution of the print mode the lower resolution is hardly visible and ideal for processing big size (tiled) output.

High

The RIP will render at double the resolution and thus be 4 times slower than normal. The extra resolution is used to add extra strong anti-aliasing and thus making small type (small compared to the printer output resolution) sharper and better defined. This mode can be helpfull at small, high-resolution printer that need to reproduce very fine details, like the numbers and marks on a dail of a watch.

 

Why

PrintFactory made this choise available in a relatively easy accessible place in the user-interface and linked to the PMM (instead of an automatic internal choice or RIP preference) so you can make a choice that fits your use-case and if needed have 2 PMMs for different purposes without forgetting to change RIP.
