Digital BW, The Print

I agree that it is hard to see the difference but have measured drops in
density of the 100% step, for example, from 1.66 to 1.58.  The nice thing
about spraying the prints is that there is no longer a risk of flaking and
the prints can be directly (gently) brushed to remove dust etc. The downside
is this density shift (others have commented in the past that the dark areas
lighten and the light areas darken).  I am in two minds as to whether to
spray and then linearise the spray steps or not spray at all.  The agreed
Best Practise is to apply polyurethane via a mayer rod but this seems too
much of a mess for me.

While I have no way to measure it, I have not seen this on the Ultrasmooth
and Somerset Velvet that I use.  I have tried the spray half the print trick
to visually compare, and see no negative effect.  On the Somerset it seems
to slightly increase saturation.  But, I might just be making that up in my
head.  I don't see it on the Ultrasmooth, however.  I'll try a step wedge to
take another visual look at it.
