Redshift is continious: SRT tells you that the ratio of the observed
frequency f' and the original frquency f from an object that moves w.r.t.
the observer is given by:

f'/f = \gamma(1 - v cos(\phi)/c),

where \gamma = \sqrt{1-v^2/c^2} and \phi is the angle which the movement
makes with the line which connects the object and the observer. Because v
can change continiously, the redshift is continious.

Ofcourse, quantumgravity may change this view when we have discovered it.
