What are some characteristics that an image is analogue?

There are no "intrinsic" properties of any image produced from a digital file. There is no standardization of A/D processing that produces the image. Therefore generalizations about 'digital images' may be faulty.

A lot of truth there.

Analog materials and processes do though each have normally recognizable "personalities" but they are malleable. Slight adjustments to exposure, filtration, lighting, or process, can many times keep us from picking out which film was used.

Still I think a majority of shots done with Velvia, processed A or D, will demonstrate it's natural palette. High contrast, faces "leaning" red, Technicolor saturation, and high sharpness.

I am talking about if you take the same negative and print it on a good digital printer vs. a wet darkroom print. The question is not that complicated. It makes no difference what you call them there are two images in front of you...one is printed in a darkroom, analogue, the other has been printed on a dedicated photo digital printer, digital, and I can see the digital print...

This would be a good discussion for HybridPhoto.com.
