    I  have posted a lot on this before, but here  are a number of web
    sources on etching. Some are particularly for copper-- all will work
    on copper.  Some of these  are  just chemical based but there is a
    little here on  Electrochemical processes which can work a bit
    faster.  To avoid too much undercutting faster is better.  All
    resists will undercut. It is more a function of the mordant and
    mordant concentration.  The ferric chloride mordant etches copper by
    reducing iron which clogs the etch zone and slows the etch not
    removed as it forms. Agitation  putting the etched surface down and
    the use of chelating agents( Edenburg etch) help control this.

    Printmaking  and printed circuit manufacture uses a lot of etching
    so you can get a lot of information by searching these areas.
