Isn't it easier to deposit light that to deposit ink jet.

When you think about it, all you want is certain portions of the
board to be exposed to light. One can think about a reverse scanner
that scan the board with a single laser point and render the
image on the photosensitive surface. This is actually how
laser printer works.

Just my 2C.
