Re: oil prints -selective inking

Gord, With the few inputs on this subject, from others much more experienced
than myself, you should, after some practice, get enough encouragement to
see some good results and many not so good, but still useful.
            As I have suggested recently, get a roll of interior decorators
lining paper ( what's it called in Canada and US?). It comes in various
grades but the dearest is only a few quid for many metres. Using this makes
the results a little less ''precious'' and you wont mind the material cost
of making all those failures. Its also wide enough to accomodate your large
formats. The darndest thing is, though, that some of my most successful Oil
prints have been on this cheap paper, but it has good qualities other than
''archival'' properties.
         A simple gelatine solution of 10% applied with a fine hair varnish
brush in a similar fashion to gum coating will provide the basis for the
matrix.
...............................................................
       I found that an addition of 2% citric acid extends the drying time of
the gelatine enabling you to brush on evenly at a lower temperature.
.................................................................

          After drying immerse the paper in a 1% Ammonium Dichromate
solution for under two minutes. The sensitizer tends to dissolve the
gelatine if left for longer.
          Many Bromoilists and Oil printers do use modified artists' oil
paints by adding extra pigment powder or talcum powder or calcium carbonate
 to thicken / harden up the ink (which is then less sticky) which helps the
swollen gelatine of the matrix to reject the colour as it is applied.
               Ca va. John.
