An other RIP to mention: FlexiPRINT. FlexiPRINT is the RIP HP supplies in the box with the 310 and 330. The premium edition is available for the 360 too for little money (as it is as an upgrade for 310- and 330-Owners too). FlexiPrint have only one window too for Job handling and one other tabbed for job properties and is really easy to use. A FlexiSIGN-PRO HP-Edition is available too. It don't use the Adobe APPE (have used Adobe CPSI earlier), but the Aurelon RIP Engine works fine. The Editor of the Premium Version have an incredible cut contour editor.
Since the Printer manages the ICC-Profiles and every compatible RIP can synchronize them (they are universal), the availability of standard profiles isn't a reason for a RIP-Decision anymore. The same is for the quality of the print raster.
There is currently one problem with onyx: it is not a bug, it is a difficulty because of the way onyx handles things. Currently, the print mode is given by the printer, there will be no printing resolution available to choose in the RIP-Software anymore. There is a dpi-setting, but this will mean the resolution of the contone file: printing with the default contone file resolution of 300dpi will work fine with big prints, but will lead to poor quality on little vectors, e. g. small text for labels. Switching to a file resolution of 600 dpi will lead to longer ripping times (still fast), but much better quality with small objects. While the resolution can be easily changed in the job properties of FlexiPRINT, in Onyx a switch to the media manager is neccessary to modify any (automatically generated) single print mode for every single media. No chance to switch it on the fly for one time faster ripping, one time better quality.
@ AF:
Specially with the 360, the profile creation is printer based, so color management hardware is not neccessary. Perhaps for the 310 or 330, because they have a densitometer only, but re-linearisation of given profiles does good work too (after getting a 360 at the end of april, we have got a 310 demo unit too this week).
