Embodiment Construction
[0024] The use of pigment ink, especially inkjet printing, ink, may be challenging because the pigments in the ink may have relatively large particles. Such inks include, for example, inks comprising titanium dioxide pigments. Large particles can be precipitated from the solution and cause the nozzle (e.g., printhead nozzles, such as piezoelectric printhead nozzles) to block or reduce the opacity of the ink. Further, when some images are printed, some ink jet nozzles in the inkjet nozzle may not be used during printing, which depends, for example, on the size, shape, and / or position of the image to be printed on the substrate. When the nozzle idles the extended period of time, the nozzle may not be kept in the perfusion state, resulting in a poor injection characteristic due to the pigment settlement. In addition, when the same print job (eg, in a plurality of similar substrates, such as the same image or series image in the plastic identification card, each printing of the subs...
