The   print   must   be   immersed   rapidly   and   evenly   to prevent  the  formation  of  air  bubbles  on  the  emulsion surface.  Be  sure  that  all  the  emulsion  gets  wet  with developer in the shortest time. Agitate constantly for the remaining developing time. Each  type  of  printing  paper  has  its  own  working characteristic,  differing  mainly  in  the  length  of  time required   to   develop   the   image   in   a   given   type   and strength   of   developer.   A   correct   print   is   one   that develops   to   the   proper   density   and   contrast   in   the recommended time. When the print is fully developed, lift it out of the developer, drain it momentarily, and place it in the stop bath. After  about  five  seconds  in  the  stop  bath,  lift  the print,  drain  it  briefly,  and  place  it  in  the  fixing  bath. Agitate  it  in  the  fixing  bath  for  a  few  seconds  and examine  it  for  any  defects  that  might  cause  it  to  be discarded.  When  the  inspection  is  completed,  place  it, emulsion  down,  in  the  fixer  and  complete  the  fixing process.  Use  the  manufacturer’s  recommended  fixing time. Some papers have a tendency to float in the fixing bath, especially if the bath is mixed a little stronger than usual.  When  prints  float  in  the  fixer,  they  should  be handled  constantly,  or  turned  facedown  to  prevent  the emulsion from being exposed to the air. The parts of a print   exposed   to   the   air   during   fixing   may   become stained. 11-35
