I searched for answers and have not found any yet. I hope you can help me. I am trying to print red lettering on a black shirt with Blazer express. I have pretreated the shirt and pressed it hard (to push down all the fibers) prior to printing. My results are white marks showing through the red ink after pressing (curing). I cure for 200 seconds at 330 degress with really light pressure. Has anyone had this type of experience? I have printed other items and have not experienced this except on solid colors especially red.
