greys cannot solve problem

[benski]

Wanted to see if anybody can give me any advice. Have been experiencing the same problem for years and still cannot resolve.
Long story short just printed 4 jerseys so in total 12 pieces and I have like 4 different greys. Sleeves do not match and front and back differ its a mess.
Ive always had this issue sometimes I get lucky but more often colors change or dont match which leaves me redoing jobs.
What confuses me it was a single print. When I print several different times I just assume conditions change but this is single print job. All pressed at the same time. using same paper, same ink etc. Same temp, same pressure, same duration. I have an ICC profile made for the printer and paper. Printer nozzle check is excellent. I checked the RGB values of all the pieces and they all match. I use wasatch softrip. Somewhere something is causing colors not to match. I really thought the answer to my problem was wasatch softrip but it doesnt seem like it. If my ink was bad, or expired paper, or conditions like humidity cause I press in the garage wouldnt all the pieces be bad. Anyway any advice would be appreciated!!!

First thoughts are
Platten is heating up from one press to another hence by the end it is very hot. Ensure it is very hot to start. Prints are drying from one press to next.

Janners

Are all these garments from the same manufacturer? What percentage of the fabric is polyester? It may be inconsistencies in the fabric mix.

I reached my set temp before first press. prints were all printed at the same time as it was only 1 print of all the pieces. but I wonder if my press is garbage. fluctuating temp...

I do cut and sew so it was a roll of fabric. Same roll I used and its 100% poly for dye sub.
