LEIBINGER inkjet coder for micro printing

For micro printing, the LEIBINGER JET3mi inkjet coder is the best choice! Its very fine nozzle enables it to print on very small parts or label products very finely or discreetly. Typical application examples of micro printing include small electronic parts, electrical cables and lines with small diameters, blisters in the pharmaceutical industry or wherever a large amount of data has to be printed in a small space.

High Precision Micro Printing
The LEIBINGER JET3mi inkjet coder can print fonts, consecutive numbers, graphics and logos on products in small sizes and with high precision that still remain perfectly legible. The extra-small nozzles (35 µm or 40 µm) make it possible to print up to 5 lines at a font height of just 0.8 mm.

Masters even the smallest print areas
Micro printing is very useful when only a small print area is available on the product or when the marking is to be applied very discreetly. The JET3mi inkjet coder allows even small products to be marked precisely at the right place—even if the print area is as small as a matchstick.

Minimal Ink Consumption
The JET3mi's small nozzle with 35 µm or 40 µm enables the generation of very small ink drops. This means less ink is required for marking, meaning ink consumption is very low as a result. The result: Maximum efficiency for product marking.
