QTR-Quadtone RIP

Hi Roy,

Do you plan to support 16 bit printing with QTR?

16 bit printing will allow us to use an ICC profile based workflow 
without losing maybe 5 - 10% of 8 bit tonal values in the conversion 
to print profile.

What I mean by this is that currently when you print with an ICC 
profile the conversion of a 16 bit image in working profile space to 
8 bit image in print profile space, rounds up or down about 5 - 10% 
of the values, so you lose about 5 � 10% of 8 bit tonal values in the 
conversion. You can see this by just taking an 8 bit target (0-255) 
and converting it to the print profile and seeing what values from 0 �
 255 you have left after conversion.

If we could print the 16bit image this rounding up or down would 
happen at much higher tonal values, beyond anything that is possibly 
visible.

Epson has released 16 bit drivers on Leopard 10.5  for most of its 
printers. Windows also now has a 16 bit printing path on XP and Vista 
(no Epson drivers as yet).

I hope we can have 16bit printing support in QTR.

Txs,

Mike
