Due to the nature of the DS4 formulation:

Perform a fresh ICC profile calibration.
This is especially important for customers producing repeat/project work that requires strict colour consistency.

Maintaining constant temperature, pressure, and time during the calendar/heat press process is crucial.
In dye sublimation, even minor variations can lead to visible colour differences.
Apply a minimum temperature of 195°C to ensure consistent colour output.
Always follow the weekly agitation of ink pouches as indicated on the packaging.
