Systems and methods of pyrometric temperature measurement and control in dye sublimation

A dye sublimation method for infusing an image on a printed sheet to a substrate, the method comprising:

• heating, by a heating section of a dye sublimation apparatus, the printed sheet to sublimate one or more dyes forming the image such that the one or more dyes travel into the substrate in a gaseous state and deposit into the substrate in a solid state to infuse the image into the substrate, the heating section comprising one or more heaters configured to radiate heat towards the printed sheet;
• remotely measuring, by one or more pyrometers of the dye sublimation apparatus, temperature caused by the radiated heat at corresponding one or more locations within the heating section;
• and
• configuring, by a processor of the dye sublimation apparatus, angular orientation of each of the one or more pyrometers.

• and
• a cooling section comprising:
• one or more cooling elements configured to cool the substrate;
• and
• one or more pyrometers with individually configurable angular orientation to remotely measure temperature at corresponding one or more locations within the cooling section, and
• a processor configured to transmit control instructions to the one or more pyrometers and receive temperature measurements from the one or more pyrometers.
