For 15 years we have been printing T-shirts. We started with an old 
Seiko, then graduated to the Epson 1160 then added an 1280. These inks 
were dye based, now we are using the Epson R1800 which uses a pigmented 
ink. We are finding a color shift when these new pigmented inks are 
heated. Will the Spyder2Pro allow me to calibrate my monitor to these 
individual machines.

We know it is the inks reaction to the paper and the ink to heat. If we 
go back to dye based inks, we have no issues.

Thanks

Monitor calibration will calibrate your monitor to a specific color temperature and brightness/contrast. You could use a printer profiler like Print Fix Pro to bring your colors back in line. Print the color target on the material you use. Apply it with heat to your fabric as you normally would, then measure the target and let the software build the profile. It goes without saying that the monitor needs to be calibrated before profiling the printer. You could also make a color adjustment layer in your image editing program to cancel out the shift but that probably is not the best solution.

This question is not on topic but ...

Do the colors shift further if a client puts one of your tee shirts
through a washer and heated dryer?  I'm guessing the color shift in
the ink may be due to the polymer coating on the pigment particles
interacting with the fuseable binder material used to adhear them to
the tee shirt.

Just like waiting for a print out to dry before measuring it would be
interesting to measure the tee shirt after processing onto a tee shirt
and then again after some cycles through the dryer. (though that might
be overkill)

Really what you want to profile a printing process is PrintFIX Pro ...
not Spyder2Pro.  That will help you calibrate the printing process. 
Having your screen calibrated will also help the overall process but
does not allow you to correct shifts in the printing process.

Good luck and let us know how it goes!
