You want full development. Not sure what developer you are using but normally an Ilford RC paper would require 1-2 minutes at 20C/68F (except Cooltone which takes longer). Check Ilford's instructions for the processing times. Check your temperatures. Continuous agitation is a good idea. Don't just leave the print to sit in the developer during development. Rock the tray (not too gently) or keep flipping the print manually.
