Hi I bought a najajet printer and every time I try to print print an image on a black tshirt the white ink is not consistant. Sometimes on the top part of the graphic it will be perfect and then toward the bottom of the graphic it look extremely dilluted. Other times it is vice-verses, and other times it is just all bad. I was told by my distributor that I was pretreating my shirts correctly but still this is not working for me. I am very frustrated and would apreciate any help. Thanks Ken
