The flash explains the operational principle of the electrophotographic print process (EP)

The laser printer is widely known. This electrophotographic print process is based on the principle of precisely transferring color toner particles to the print substrate which is then rendered resistant to secondary processes (e.g. sealing) by fixing them to the substrate.

CSAT modified this principle fundamentally so that it has little resemblance to the original. One of the most important elements here is the automation of the EP process which allowed for a process interface to the production line – this innovation is protected by many patents. We also set standards in the area of design, for example, the cabinet of our printer which complies with GMP.

Operational principle of the DOD print process (Drop-On-Demand)

This technology traditionally known as “inkjet” was thoroughly redeveloped and today significantly contributes to more reliability in this printing process.

This print principle is based on programmed firing of very small droplets of a special ink through small jets. The diameter and the number of these jets determine resolution (e.g. image definition) - smaller jet diameter and larger numbers of jets per area result in higher quality of the printed image.

Quality and reliability of a DOD system is governed by the number of print heads used: Fewer print heads equals more reliability.

CSAT takes this fact into consideration and achieves full color at a print width of 100 millimeters with only four single print heads. This is only possible since up to 100 millimeter print width and 600 dpi resolution stacking of single print heads are not required.
Simple and effective!
