transparent PNG appears black

[Marianne]

On the master slide I have one solid picture (very light
beige) inserted as "background/fill effect". On the top
of it I've placed a transparent PNG, only colored blocks
on the top and bottom + our company logo.

The reason I do like this is that I don't want to print
the light colored background; I want it to appear as
white when printed.

PROBLEM
On some computers the slides appear as black. The only
reason I can imagine has to do with this transparent PNG.
Can it be the graphic card or some option in PowerPoint?
- What's your opinion and can you help with a solution?

Since it's the CEO who always has this problem it's a bit
embarrassing for me... he also has a super pc I've been
told.

Thanks,
Marianne

Well, if you're printing in black and white, you definitely want to
preview in grayscale and if things look bad, alter your grayscale
settings, but there might be indeed be an issue with the PNG. If you
create PNGs on a Mac, you need to make sure that there is no color
profile associated with the file. Otherwise, the image will appear
incorrecct on CERTAIN PCs (and on others, it will be fine). Open the
PNG in Photoshop, select all, create a new Photoshop document, and in
the options, make sure that "don't color manage this document" is
selected. Then paste and resave.

It's on the screen it looks black. Even though the
setting in PP is colour.

I have created it on a pc and it's only used on pc's.

I realize that this mentions a Mac, but you will want to make sure that you
color profiles are turned off in Photoshop (whatever image editor) on the PC
as well.

When printed or when viewed? Printing and transparency isn't well supported in
PowerPoint.

What happens if instead of using the picture as a background fill effect, you
insert it on the master slide, send to back, set it to fill the frame, then use
the B/W settings to tell it not to print in B/W?
