Digital BW, The Print

Steve,

On a Windows PC, choosing 'Let printer determine colors' means that CS2 
sends the image with its working space profile to the printer driver. The 
printer driver then uses Windows ICM2 to do the conversions necessary from 
the working space to the appropriate printer profile, assuming you have 
chosen the correct setting (color controls, photoenhance, icm) for this in 
the printer driver and not turned color management off in the printer 
driver. This is the normal Epson mode for printing with its profiles. These 
driver settings also include the new AdobeRGB setting that apparently 
enhances the color gamut of the R2400.

On the other hand, if you want to use custom profiles, you usually turn 
color management off in the printer driver and choose 'Let Photoshop manage 
colors' in CS2. Then Photoshop uses its own ACE conversion software to do 
the conversions from working space to custom printer profile, and the 
printer driver does not do any color management. You may occasionally leave 
color management on in the printer driver (see below).

Then if (with your third hand) you want to print a printer profiling target, 
you choose Color Management off in CS2, and choose whatever setting you are 
going to use for printing in the printer driver. This will usually be no 
color management, but some get better results with earlier printers by using 
color controls/photoenhance in the driver.

And (with your fourth hand) if you want to print using the AB&W setting, NOT 
using custom profiles, you select 'Let printer determine colors' in CS2 to 
make sure that CS2 is not doing any color conversions. The printer driver 
will then do whatever it wants to give you the AB&W; I would have thought it 
would take notice of the working space profile, but I haven't yet sent any 
with different working spaces to test this.

I can remember some years ago on the Epson inkjet list some of us compared 
all the different combinations of settings in photoshop and settings in the 
printer driver and worked out which ones gave the same results and which 
ones gave different results. Quite fun at the time! It led to some lively 
discussions on the 'right' and 'wrong' way of doing things, and slowly 
people began to realise that there may be more than one 'right' way and many 
more than one 'wrong' way. Macs do have some dialog differences to Windows, 
and this often caused a lot of confusion on top of everything else.

I have no problem with your way of doing the AB&W printing; if it works - 
fine. I simply replied 'n' emails ago saying that I didn't think it was the 
only way of doing AB&W printing. I may even explore your way of doing it - 
howzat?

good-natured games and to see the Aussies lose for a change!)

If you Let Printer Determine Colors colour management is likely not turned
on. I think Epson likely stresses No Color Management to simply avoid this
type of confusion - people thinking they need a color ICC profile when they
don't.
