Most electroless copper deposits are fairly rough in terms of topography
and generally provide an excellent surface for dry film adhesion.
Generally, no precleaning after electroless is required if you are going
directly to imaging.(assume hold times between electroless and
photoresist lamination is less tha eight hours)
Depending on deposit thickness, scrubbing is  not recommended anyway.
Good luck.
