Accurate color printing from ios

[FrankG]

Hi, can anyone suggest a suitable way to accurately print color or send a color accurate file for printing from ipad? My old ipad was color calibrated and since purchasing a new ipadmini6 l discovered that they cannot be calibrated anymore. My files are all on icloud.

Forgot to mention, all my files are pixelmator ios created. Most grateful for any suggestion
