Abstract
The present disclosure is drawn to a coating device and a method of manufacturing a coated media substrate. The coating device can comprise a pre-moisturizer and pre-heater unit to apply heat and moisture to a media substrate; a coating composition applicator to apply a wet coating composition to the media substrate after it has been heated and moisturized by the pre-moisturizer and pre-heater unit; and a dryer to receive the media substrate having the wet coating composition applied thereto and to remove moisture, thereby generating a coated media substrate.
Claims15
A coating device, comprising:
- a pre-moisturizer and pre-heater unit to apply heat and moisture to a media substrate;
- a coating composition applicator to apply a wet coating composition to the media substrate after it has been heated and moisturized by the pre-moisturizer and pre-heater unit;
- and
- a dryer to receive the media substrate having the wet coating composition applied thereto and to remove moisture, thereby generating a coated media substrate.
A method of preparing a coated media substrate, comprising:
- feeding a media substrate into a coating device, wherein the coating device comprises a pre-moisturizer and pre-heater unit, a coating composition applicator, and a dryer;
- applying moisture and heat to the media substrate within the pre-moisturizer and pre-heater unit at a relative humidity from about 50% to about 100% and a temperature from about 40° C. and 200° C. to generate a pre-moistened and pre-heated media substrate;
- applying a coating composition to the pre-heated and pre-moistened media substrate with the coating composition applicator to generate a coated wet media substrate;
- and
- drying the coated media substrate to generate the coated media substrate.
