Photoshop CS/B&W

Photoshop CS/B&W

2004-01-24 by Ken Carney

Finally got around to upgrading to PS CS this morning.  I see that "b&w"
prints that were coming out with a magenta cast using the Epson 2200 driver
are now coming out with a slight yellow/green cast, but for all practical
purposes a warm b&w print as opposed to the very noticable magenta.  I'm
using the Epson 2200 with Epson inks.  I'm working from the same scans as
with PS7, and the only difference is that I'm using 16-bit layers instead of
8.  Printing is with the Epson EEM MK profile and no color adjustment.  Does
anyone know why this might be?

Ken,

did your other settings stay the same? Color and gray spaces in PS color prefs , Epson 
driver CM settings (print space/doc space)?... If so did you test both 8 and 16bit files 
to see if they come out any different? Is the Epson driver the same as before? and are 
the files grayscale or RGB? Is this on a Mac or PC?
Your question suggests that maybe CS is handling grayscale printing differently, but 
it's worth eliminating the other variables first....

RE: [Digital BW] Re: Photoshop CS/B&W

Good questions, Antonis.  I will have to approach this in a more structured
way.  The PS color space (Adobe RGB 1998) and the Epson print space (Epson
2200 EEM MK, no color adjustment) are the same.  The files are RGB (Portra
b&w C41 film, which scans with a slight color cast, so converted to b&w in
PhotoKit).  The computer is a PC (Windows XP).   I didn't think to test both
8 and 16 bit files.  What I did was start with a 16-bit RGB scan that I had
used to make an 8-bit print, and did similar contrast adjustments with CS,
only now with 16-bit layers.  After drying, the prints (EEM) are pretty
green under daylight, but fairly neutral under tungsten or fluorescent.  I
would have thought that if the PS eyedropper tool is showing me that RGB
values are equal, and I print on the same paper with the same profile,
Photoshop would not influence the print.  But maybe not.  I'll work on it
some more and report back.

Someone mentioned that Photoshop's algorithms for doing adjustment layers
have lots of shortcuts in them to make them more efficient, at the expense
of accuracy, since they were designed back when we were all running much
wimpier processors. And these shortcuts are probably retained in the latest
version, so that old fles opened in PS CS won't look different. But it's
possible that when they added 16-bit adjustment layers, they decided to do
the 16-bit versions of the calculations without these hacks, since they're
no longer necessary. If you still have PS7 installed, you might try some
simple tests to see if printing files without layers, or with 8-bit layers
only, exhibits the same shift between the versions.

Right, that's what I plan to do.  The prints with CS sure look different to
me, but then I need to do some structured testing.  I recall reading
somewhere that PS has always had 16-bit layer capability, but it was
disabled because of the hardware limitations then.  The only thing I know
for sure right now is that I need a better PC.  I have an older 1.7 P4 with
1.3gb of ram, and it does gasp on larger prints.

RE: [Digital BW] Re: Photoshop CS/B&W

PS is probably not the cause of the color cast.  When Epson drivers a passed a file with the RGB values all equal, it can't produce a neutral print.For that matter, IP5.6 can't produce a neutral print with an RGB file where the values are equal, and the print is being made with a color profile.  I've heard this will change with IP6, but I haven't heard that from any authority.  (I'm talking about Ultrachrome inks.)

I'm interested in this, because I'm considering getting a RIP. What do you
mean by not being able to get a neutral print with a profile? Does IP not
use a conventional ICC profile to translate Lab to whatever it needs
internally? If not, does that mean that you have to use some built-in tool
for "profiling", rather than some 3rd party product like ProfilerPro?

IP uses 'standard' ICC profiles.  The profiles are done by Colorbyte, and are provided free to IP users.  One could spend the money to have custom profiles made, but I've only heard of one or two people that thought the custom profiles were better.
 
The point I was trying to make is that while IP produces b&w prints that are dead on neutral with the gray files and gray ICC paper profiles, it can not, as is the case with Epson as well, produce a neutral b&w print from an RGB profile that has been converted to have all of the R, G, and B values equal.  In theory, this should be able to produce a neutral b&w print, but it doesn't happen.  Once the same file is converted to a gray file (Gamma 2.2 would be typical, I believe) and printed with a gray paper profile, all is well.

I've already spent the money on profiling software, so I want to make sure I
can use it with whatever RIP I get.

I'm really not getting what you're saying about equal R, G and B values.
What workflow are you saying doesn't work for B&W? Are you saying that you
can't create an RGB file with equal R, G and B in some abstract color space
like Adobe RGB, and get it to print neutral? Or are you saying that once
you've converted to the printer's color space (more precisely the RIP's
color space), you no longer have equal R, G and B?

Also, it sounds like you're saying that IP has some special kind of profile
designed only for B&W. Is that the case? If so, it's something I've never
heard of, but it sounds like it could be useful.

Correct.
 
As for gray ICC profiles, go to Colorgytes download site and you will see their listing of profiles.  The listings are broken down by printer/ink type, and color and gray profiles.  The gray profiles will produce a neutral b&w print from either a gray file or and RGB file.  I believe that most people using IP will send a gray file to IP instead of an RGB file.
 
There are several vendors that have an IP demo download available.  Give it a try. It prints a severe watermark on each print, but you can see how it works.

It would seem that if you can get it to print neutral grays with a grayscale
profile, but can't with an RGB profile, then it's doing a different kind of
black substitution in grayscale mode that perhaps is inappropriate for
color. Does that sound right?

Anyway, thanks for the info. I'll check out the demo. It sounds like it's
worth experimenting with it.

Yes.  In the grayscale mode IP uses only 4 inks, instead of trying to 'make' black or shades of gray with all seven inks.

RE: [Digital BW] Re: Photoshop CS/B&W

2004-01-27 by Ken Carney

Tom: Thanks for this info.  I too am considering purchasing the IP rip for
my 2200.  I want to use the Epson inks since I often like to tone the prints
slightly.  I was thinking that with IP I would have only one printer and be
able to print neutral b&w and toned prints, as well as color.  By "toned", I
mean a print somewhat cooler or warmer than neutral, or maybe even a
platinum or sepia tone.  Though I don't have it handy, I recall that IP
allows an adjustment for warmer or cooler prints.  Do you know if this
requires an RGB file, and hence some unpredictability in the outcome, as I
gather from your explanation.  I have worked in RGB since I'm fond of
PhotoKit Sharpener and PhotoKit, which require RGB files.  It seems I could
as a final step convert to grayscale, but does that mean I'm cut off from
selecting warmer or cooler prints in IP?  Or worse, not converting from RGB
and having unwanted color casts from a sepia or platinum "toned" print.  I
have never used a rip before, so will be grateful for any comments, even
though I probably haven't phrased the questions properly.  The IP rip seems
like a fair price considering all the profiles.  Thanks for any help.

Regards,

Ken  -
 
The 'toning' with IP is quite nice and very precise.  The tone ranges from cool to warm, and moss to mauve.  At least w/IP5.6 you can't really get a platinum tone.  But, the control is very precise.  
 
As for the RGB considerations, you can actually feed IP an RGB file, and have it print it with a gray ICC paper profile.  That works fine.  I can't really see much difference between feeding IP an RGB or grayscale file printed with the same gray paper profile.  You can certainly do everything you are doing today with respect to the RGB work and still print neutral b&w with IP.  (IP gets a little strange when you feed it a gray profile and try to print with a color paper profile, however.)
 
If you want/need to print color and b&w on the same printer, IP is a great way to go.  With the realization that judging quality and desirability of what we turn out is largely subjective, many people that see the IP b&w side by side with the dedicated b&w systems find the results at least equal.  Some prefer the tonality that you can get with IP over the MIS or Cone inks.  And, some the other way.  In short, the IP b&w produces a good product.  The color is equally as good, although the difference between the IP color output and the Epson color output is not as great as the b&w.
 
If you are really interested in a platinum look, you might explore the "pure carbon" inks that Paul Roark has been working with.  I've seen a couple of Paul's pure carbon prints, and for subject matter that would lend itself well to platinum, the pure carbon is really beautiful.  I can't match that look with IP.  I've been tempted to buy one of Paul's excess printers just to do the pure carbon printing on.  I probably won't, just because of room (I've already got a 9600 and several HP printers) considerations.  But, the cost of dedicating a printer to that use is not great.

[Digital BW] Re: Photoshop CS/B&W

2004-01-27 by photosimon2001

From reports on the Imageprint yahoo group, it sounds like version 6 
of IP may give greater ability to tone and colorise black and white 
images but without losing the benefit of nil metamerism. There was 
talk of being able to run a colour profile and a grey one at the same 
time on a single print so that where R=G=B it used the grey profile 
but for everything else it used the colour - so you get the benefits 
of colour but pure neutral greys.
