The softer nature of the inkjet dots do allow some contrast control too. Do
you find you get a tight enough sandwich Ralph, without some form of
pressure applied to the centre, using just a glass sheet?

Yes, I have compared it. There is no sharpness difference to speak of.
Emulsion to emulsion has some disadvantages, since we are contact printing
high-density (4+) dots. There is no light going through the dot! This means
exposure and filtration make little difference. By having the film thickness
as a 'spacer', some diffusion is helping to get some exposure and contrast
control back. But it is too small to lose visible resolution. Yes, I'm using
the enlarger as a light source.

Stopped down ( to make it more of a point source)?
Emulsion to emulsion should be sharper, especially with a light source that
is less than a point source. Of course you would have to flip the image
before it goes to the image-setter for correct right-left reproduction.
Have you compared the difference in sharpness between the two negative
orientations? (emulsion up and down)
Thanks,

My digital negatives are 11x14 or A3 size. I have no easel. The paper is
laying on an MDF board, negative emulsion-up on top, and a heavy piece of
glass on top of that.

What size negs do you make and what sort of frame or easel do you use? I
would be very interested, it can make a significant difference.
