Digital BW, The Print

This surprises me.  I thought that a Lightjet print was in essence a
traditional print in that it is the exposure of photosensitive paper to
light, the only difference being that the light is emitted by lasers rather
than a bulb in an enlarger.  I also thought that the post exposure process
was essentially the same as the wet darkroom (albeit automated).  Given, in
many people¹s estimation, the goal of inkjet printing is to be able to match
the quality of the traditional wet process I would expect a  Lightjet to be
the current state of the art in printing from a digital file and well in
excess of inkjet, both in terms of dynamic range and neutrality.  I would
also be very surprised if a grey scale psd image (left in Gray Gamma 2.2 or
flipped back to Adobe RGB or whatever) produced anything other than a
neutral image ­ it is not as thought the laser needs to use dithered colour
light to produce grey. On this basis one ought to always be pleasantly
surprised by Lightjet prints vs their inkjet equivalents.

<< I have found that the LightJet prints tend to have a shorter range
and steeper contrast than inkjet prints. They seem to lose information above
a white value of 250 and below a black value of 5, so the work that you do
on a particular file to be made into a LightJet print will need to be
different from one that you might edit for inkjet printing.>>
