One way to get deeper blacks is to selenium tone your prints. It is very easy to do once you have washed your prints just give them a few minutes in a selenium bath in daylight either diluted from 1+3 to 1+ 9 which will give you deeper blacks with a slight colour change if you leave them long enough in the toner. 1+19 or weaker will deepen the blacks without the colour change. Normally you can give them 2-5 mins but they can be left much longer to get different effects. I usually use 1+9 for about 3 minutes to improve the blacks and contrast but different papers react differently just try various dilutions and times and see what you get.
