Digital BW, The Print

Any idea what would cause this? Printing on Gold Fibre Silk. Applied Paul's curve, UT14-IlfordGold-N-1, to the rgb-raw-16.psd file and to the  21 step RGB file, printed the 21 step on my 1400 per the glossy paper driver settings, dried it and took readings with my Colordata spectro.  I double checked the ink positions in the 1400 and they appear correct.
