Custom remote QTR profiling for Piezography K6 and K7 inks
2008-12-16 by Jon Cone
I just completed a custom profiling experiment for the Piezography K7 and K6 inks. I have been able to make K7 and K6 profiles of perfect linearization using a remote method in which the printing of the target and the measuring of the target both take place at the users location, while the profiler app runs at my location. The data dumps were emailed to me as text files by the users, although one person extracted and sent only the L values (which during the initial experiment was very helpful.) The data was imported into the Piezography K7 profiling system and converted into QTR Curve, and emailed back to the user (usually within a half hour.) This method works really well. I now have process for Eye1, DTP70, and DTP40. Users read their targets with MeasureTool and Save the data to text file. I import the text file and produce a linearized output of seven (or six) 256 point curves that are specific to the printer. I did not get any volunteers on the ColorVision device. But if someone can work out the data dump to be useful to L values, there is no reason why it should not. I did not have time to evaluate the qualitative differences between all of these spectral devices. In the case of the x-rites each was able to do what what expected, which is all that matters in the end. The AB values were not used. This method is geared directly to the users printer without regard to any averaging. It should make for very perfect output on a particular printer, and would certainly be better than the canned K7 profiles we provide to QTR or ship with current systems as an installer CD. I plan to offer this process after I streamline the procedures on my end a bit. Right now I can K7 profile for Epson 800, 1800, 1900, 2100, 2200, 2400, 2880, 3800, 4000, 7600, 7800, 7880, 9600, 9800, 9880 printers. I can K6 profile for Epson 1270, 1280, 1290, 200, 300, 1400, 7000, 7500, 9000 and 9500 printers. It is also possible to do remote K6 and K7 glossy profiling of the MPS inks if the user is willing to spray or create their own GO workflow. I do not offer any canned MPS profiles for the glossy Piezography inks. Jon Cone Piezography
