    Ive had a similar issue. I dropped the blanket temperature down, in one case to 130 degrees (I think the lowest you should go is 125!) and it really made a huge difference, especially in the lighter tint areas.

    It turns out my ITM sensor was taking a wrong reading. Once the temperature had been calibrated, the light tints and photos looked SO much better. I still drop the temperature to about 145-140 when running light tints, but the quality is so much better.
    It might be worth looking at what temperature your machine is running at, and calibrate the ITM Temp.
