Digital BW, The Print

Hello

I bought some re-fillable carts of eBay and filled one with Eboni and the remainder with clear fluid from MIS.  I have been unsuccessful in creating prints with dynamic range -- the prints are super contrasty -- 5% step wedge has visible gradients between 90% - 55%, otherwise there is minuscule visible difference in progressive steps.  I have downloaded QTR and tinkered to no avail.  Any thoughts are greatly appreciated!
