Although your monitor appears to look great to you, it may not actually be close to standard. Thus, when you send it to your printer, the printer misinterprets the color data.
What software program are you using to edit your images and subsequently print?
Unless you have a program that uses color management and profiles, your best bet is to find the recommended settings for the type paper you are using and your printer (if they are available from Ilford). If you have a color managed software program, you would want to download the proper ICC profile from Ilford for the paper/printer combination, then disable color managemnt on your printer and allow your software to control the color output using the color profile.
Barring that, you're going to have to get a test image to experiment with and try to figure out what settings work best. This is a huge trial and error process that will use a lot of ink and paper.
