Abstract
A meltable ink which is solid at room temperature and liquid at elevated temperature, used in combination with an inkjet printhead for the image-wise transfer of the ink to a receiving material, wherein the printhead contains a number of ink ducts, each ink duct leading to an opening for jetting ink drops from said duct, which ducts are formed in a duct plate made basically of carbon, whereas the ink can penetrate into the carbon in such manner that if an element made from said carbon is enclosed by the ink for about 20 hours at a temperature of about 130° C. said element has an increase in mass of more than 1.5%.
Claims11
A meltable ink which is solid at room temperature and liquid at elevated temperature, and used in combination with an inkjet printhead for the image-wise transfer of the ink to a receiving material, wherein the printhead comprises a number of ink ducts, each ink duct leading to an opening for jetting ink drops from said duct, which ducts are formed in a duct plate made basically from carbon, wherein the ink penetrates into the carbon in such a manner that if an element made from said carbon is enclosed by the ink for about 20 hours at a temperature of about 130° C., said element has an increase in mass of more than 1.5%.
Use of a meltable ink solid at room temperature and liquid at elevated temperature, in an inkjet printhead for the image-wise transfer of the ink to a receiving material, wherein the printhead comprises a number of ink ducts each leading to an opening for jetting ink drops from the corresponding duct, which ducts are formed in a duct plate made basically from carbon, wherein the ink can penetrate into the carbon in such a manner that if an element made from said carbon is enclosed by the ink for about 20 hours at a temperature of about 130° C. said element has an increase in mass of more than 1.5%.
Use of a meltable ink composition which is solid at room temperature and liquid at elevated temperature for producing solid units of ink for use in an inkjet printer provided with a printhead for the image-wise transfer of the ink to a receiving material, wherein the printhead comprises a number of ink ducts each leading to an opening for jetting ink drops from the corresponding duct, which ducts are formed in a duct plate made essentially from carbon, wherein the ink can penetrate into the carbon in such manner that if an element made from said carbon is enclosed by the ink for about 20 hours at a temperature of about 130° C. said element has an increase in mass of more than 1.5%.
An inkjet printhead having at least a part thereof made of carbon, which is penetrated with a meltable ink which penetrates into the carbon to such an extent that said carbon part has an increase in mass of more than 1.5%.
