I to have had issues using the same set up as you. Sometimes the problem is that your monitor is not calibrated for your printer. This would cause the picture on your monitor so look different from what your printer is seeing when it prints. I have not calibrated my monitor to my printer so i wouldnt be able to help you there, but there are quite a few links to set that up. What i have done is print and press the design on a sample material and then adjust the color from there. I had an orange rich design that i had to do, and i had to make the color look almost red on my computer to have it print out a rich orange color on the press. I am not a pro at sublimation, but I have had a lot of issues as well, and this is one way that I have solved my issue. Good luck and Aloha
