Hi dan this artical from amateur photographer 1923 might help "Bromoil in India, Bombay" Bromoil in a hot climate...1923. ...in fact we have heard from others in India that many photographic processes which can be worked with complete certainty in England are altogether differant at high temperatures which are unavoidable there.-May I suggest the following solution to your difficulty.....the use of a neutral fixing bath may be avoided, and hence the thousands of blisters, by bleaching the bromide print immediately after development-leaving the operation of fixing-out at this stage. After bleaching and washing the print may be fixed in an acid bath. It would be well, however to omit the alum, using only potassium metabisulphite. The strength of the hypo bath need not exceed 1.oz, in 10.oz, of water, and after five minutes immersion of the print the bath may be gradually weakend until no trace of hypo remains....kirk again..I only ink up bromoil and oil prints in the winter from October until April once the temerature reaches 20.c I stop because I get flat-muddy soft prints......In france and europe bromoil workers use very soft ink..which can be poured from a milk jar its that soft and they get nice contrasty images the reason for this is they soak the matrix at a high temprature i.e. 35.c as a starter, but work at much higher levels than this..The other possible cause of the ink taking all other is you might be printing to dark, try to keep the highlights bright and clear if you can, are you using digital negatives again this can result in the matrix being over=printed..try a more dilute developer....................hope some of these ideas might point you in the right direction...kirk
