with a plane surface that will be reticulated, my question is
this has to be done before soldering the ring or after?. I ask this
question because if I reticulate before soldering the pattern of
the reticulation won't match and if I reticulate after soldering
this can be damage.
Alvaro, for true reticulation (versus torch texturing), it is not
possible to reticulate the ring in a band form. First, your
reticulation temperature is higher than your solder temperature.
Second, you need a heat reflective surface to get the high relief for
reticulation. Also, when reticulating, your metal will pull in from
the sides to provide material for the "mountains," and thusly, will
be uneven on the edges.
However, to solve the problem of edges that will not match on the
solder seam, consider using something else as part of the design,
such as a plain piece of sterling for the back side, or for the front
side with a set stone(s). You could use a piece of gold wire to where
the ends meet as a design element, or some other creative design
element to visually separate the mismatched edges.
For a ring, it is best to have an inner band for strength and
comfort that is plain, with the reticulation applied to the outside.
It is also wise to provide some type of guard wires to the edges of
the ring that will prevent unwanted wear to the reticulation.
