What Is Industrial Inkjet Printing?
Inkjet technology is the process where a print-head ejects tiny droplets of ink onto a substrate without the print-head actually making any sort of physical contact. Dots of different colored inks combine to give photo-quality images. The main challenge lies in achieving a high level of precision and reliability. The dots are smaller than 70 microns and hence, the heads need to be positioned precisely in order to achieve good resolution and print quality. This precision is only achieved using a combination of science, technology and design. Although inkjet technology has been around since the 1950s, its application in an industrial environment is being explored only of late. Industrial inkjet printing systems are broadly classified into two categories-continuous printing (CIJ) or drop on demand (DOD), with variants within each classification. In the case of continuous inkjet technology, the drops are ejected continuously from the print-head, whereas in case of drop on demand techn...
