The tiny variations you are seeing are to be expected with any device. 
Comparative specifications (comparison of each manufacturer's published 
specs) show the PFP Spectro to be as accurate as the EyeOne  Spectro, 
and ten times as consistant, partly due to the repeatability of LED 
devices, and partly due to the fact that the PFP spectro is a dual 
channel device (it has both a reference channel and a measurement 
channel, like a SpectroLino, while the EyeOne has only a measurement 
channel). Even more amazing is that the PFP device ranks as 20 times as 
consistant as the X-Rite Pulse.

Subject: [colorvision_group] Spectocolorimeter consistent?

   How consistent or stable is the Printfix Pro's spectrocolorimeter?

WHile I really don't know anything currently about the figures
generated by the printfix pro but keeping at one patch and reading a
number of times - every read produces a different value although the
reader was not moved at all? Is this ok? The lab values differ readings
are like 1.34 and then 1.38 and then 1.25 and so forth....

Does anyone know if the other profiling system will produce identical
readings? Why can't the printfix pro produce spot on consistent
readings if its using LED which are touted as stable?
