Printing on non-porous materials has always been a major problem in industrial applications. The high degree of maintenance required to keep conventional coders operating with solvent based inks has made many companies opt for manual marking as a cost effective alternative. With MARSH® Non-Porous Coders, printing on nonporous materials can be accomplished with the same relative ease as printing on porous materials. This breakthrough in Non-Porous coder design opens up in-plant printing opportunities which previously were regarded as too costly to consider.
Inks used to print on porous materials dry through absorption into the material being printed. Inks used to print on non-porous materials dry through the rapid evaporation of the ink solvents after the print is applied. Since the ink solvents must evaporate very rapidly on the printed material, they also evaporate very rapidly from the ink rolls and ink wells of conventional coders therefore requiring constant maintenance.
The proprietary design of the MARSH® Non-Porous Inking System effectively eliminates the rapid evaporation of the ink solvents from the ink roll and additionally provides for convenient automatic re-inking of the roll without interrupting the printing process. After many months of design engineering and field testing, the Non-porous Conveyor Line Printer is both simplistic in design and extremely effective in operation. The relatively low cost of this system makes in-plant printing of all types of non-porous materials a practical reality. The following pages of this manual explain the installation, operation and maintenance of Non-Porous Conveyor Line Printer and are the key to trouble free non-porous printing.
