Not sure i did this correctly and looking for input. The cyan channel is block so I moved the ink to the orange channel which was not used and has flush in it and flush them. Using TextWangler open Library-Printers-QTR-quadtone-Quad7900K7-EpsonEnhMatte.quad. Copied # C curve and replaced # OR curve with # C numbers and placed a zero in # C curve. Ran a test print and looks great.
