Ilfochrome is by far the best way to make prints from transparencies and although there are some difficulties relating to contrast control I don't think that making contrast masks is the only solution. I have used two bath black and white print developer in a Jobo to deal with the high contrast problems with great success. You need to make a test to determine development time in each bath, and that is not difficult. I have made prints from the same transparency using the two bath black and white dev and then using the Ilfochrome chemicals and the reduction in contrast using two bath is hugely significant. I first did this some 20 years ago and the prints are still in pristine condition today so there is no loss in permamence. I also used ordinary black and white fixer but had to use the Ilfochrome bleach.
