For the majority of Videojet continuous inkjet (CIJ) printers, the recommended distance from the end of the CIJ printhead to the product is 3/16” or about 4mm. When the printhead is closer to the product, the code gets smaller and the printed drops are closer together. When the printhead is further than 3/16”, the print height becomes taller, the printed drops are farther apart, and the drops land with less accuracy.
