Bits per pixel?

[shookiesandmilk]

I have been given specifications for uploading a PDF to a database.

• Black and White “bits/pixel:=1”
• 600 dpi
• 10 MB or lower

I thought they meant grayscale but apparently there is a distinction between grayscale and black & white? Can anyone guide me on how to adjust these settings, thanks very much.

Image > Mode > Bitmap

And naturally the Resolution needs to be as requested.

Thank you, that did the trick!
