What do you mean by 'design in Cricut?' What software are you designing in?
I'm assuming you are producing vector designs for your cutter and need to do a print & cut that's printed with sublimation ink on sublimation paper. To do this, you need to be printing from software that handles ICC profiles, such as Photoshop, Coreldraw, Illustrator or Gimp.
Does your cutter design software allow you to save as a PDF, so that you can save the design, along with registration marks, and print it from, say Photoshop?
If your design software doesn't allow saving ad PDF then install a third party printer driver (such as the free Bullfrog) which, when printed to, allows you to save out a PDF.
