Abstract:
An ink jet printer for printing on a coated media, the ink jet printer comprising:an ink ejection device for ejecting ink onto the coated media, the coated media having a base layer of a non-gelatin material and a surface layer formed of gelatin, the gelatin surface layer exhibiting an increase in surface area dependent upon temperature of the gelatin surface layer of the coated media, the increase in surface area of the gelatin surface layer absorbing an increased amount of the ejected ink; anda heating device associated with the ink jet printer and located in proximity to the coated media, the heating device emitting heat while the ink ejection device ejects ink onto the coated media, the heating device heating the gelatin surface layer to a glass transition temperature range of 30 to 50 degrees Celsius to control the surface area of the gelatin surface layer and thereby penetration of ink into the gelatin surface layer of the coated media.
