I thought I'd try sub printing to a tshirt. Customer sent me a black and white photo albeit in RGB, I printed this on my Ricoh using the power driver, the result had a very pink cast to the print and although I tried converting to greyscale, LAB and CMYK the print on paper remained the same. I thought I'd take a chance and press on the shirt anyway and to my surprise the result was very good, no pink cast and pretty much as displayed on screen. I appreciate that the finished sublimation results are always very different from the paper print before pressing but was surpised (pleasantly) how different they were in this instance.
