LCM or “large character marking” uses DOD inkjet technology for print-on-demand case coding. Both high and low-resolution LCM printers are typically used for secondary packing where a larger font is required. While continuous inkjet (CIJ) fonts usually range from 1/8th of an inch to ½ of an inch in height, LCM characters can be over two inches tall.  Like other DOD printers, the code dries more from absorption than from evaporation, which can be quite slow on non-absorbent materials.  This makes LCM most suited for corrugate and other porous materials and not glass, metal, or plastic.
