Colour management in PP?

[Markus Hänchen]

Hi,

is there any way to influence the colour management in PP? I have the
simple example of black and white SEM photograph (in Photoshop it shows
as having indexed colours, sampling it shows always the same values for
red, green, and blue).
Inserted it into a PP slide, looked still pretty neutral (similar to
what it looks like in PS). Printing it out on a colour laser it comes
out blue-ish and grey-ish. Inserting the same image into an InDesign
document, looks fine on screen and fine when printed out using the same
printer.

InDesign's CM is set 'Europe ISO Coated' using Rich Black for both
screen and printing and I get good results using either the PS-CM or
InDesign's-CM (using the same 'Europe ISO Coated') for printing.

In short, is there a way to improve things in PP?

Cheers,

Markus

PowerPoint offers no CM whatever. It pretty much sends images as-is to the
printer. You might have better results going from PPT to PDF and printing from
Acrobat/Reader.

Thanks for the quick answer.

If you have InDesign it suggests you may also have Acrobat. If so, have you
tried using the Acrobat PDF printer rather than the PDF button in the Print
dialog? Perhaps some of the settings available in ColorSync, PDF Options
&/or Printer Features will render better results.

I did a lot of reading about CM and understand it a bit better now.
There is a tiny little bit of CM that one can use when printing from PP
on OS X, however it far from bullet-proof.

Basically, PP uses ColorSync when printing on OS X. In the print
dialogue box, choosing ColorSync from the drop-down menu gives you two
options: 'Standard' (which apparently uses any ICC profiles assigned in
ColorSync to one's printer) and 'Printer-specific' (which apparently
converts everything into device-independant colours, which the printer
should then interpret).

In practice, only if I use a grayscale JPEG or TIFF (grayscale, not
RGB, not CMYK) in PP and select the 'Standard' ColorSync setting, the
printer uses its black toner only and produces a neutral grey. Whether
I have an ICC profile assigned in ColorSync or not at all does not seem
to make a difference.

My older version of Mac OS/X and PPT doesn't include this feature so I can't
try it. In Mac apps, some of the features you see in the print dialog box are
supplied by the application, some by the printer driver. It may be that the
ColorSynch settings are supplied by driver or OS but it's up to the application
to respect them or not. Under Windows it's something like that.

Still, if you set a color to pure white, black or gray as RGB 127,127,127 for
example, that's what PPT should/will send to the printer driver. If it and the
OS and ColorSynch are working together, you should get something like a medium
gray from the printer.

What you won't get from PPT is the other end of CM: adjusting what you see on
screen to what will come out of the chosen output device when you print.
