PDF / A-1a: OutputIntents for Black and White Images

Question

I am trying to create a PDF / A-1a compatible file that contains only a black and white image (i.e. CCITTFaxD).

I'm having problems with "OutputIntents". In principle, I can’t find the solution I made for 1-bit images.

Does anyone know the profile that I intend to use?

Alternatively, how can I not use OutputIntent for b / w images?

Note. I have work with grayscale images and color images.

A1-a? The brave man. A1-b was annoying enough ... where I plunged everything into RGB. Inelegant but effective.

IIRC, , - . , RGB, deviceRGB, , .

OTOH, PDF/A1 , :

• "6.2.4 :.... , 6.2.9"
• "6.2.9. , , RelativeColorimetric, AbsoluteColorimetric, Perceptual Saturation. : - RelativeColorimetric."

Err, . , . Fooey.

Ah, Image Dictionaries, General, 89. ColorSpace. . /DeviceGray .

, DeviceGray DeviceRGB, , (, Acrobat pro 9, , ).
