1 Ink jet printing
Ink jet printing enables contact-free marking to identify, date or customize a product. Your printer
uses the "deflected continuous jet" principle with dot-matrix type characters.
1.1 Dot-matrix characters
Each symbol (letter, digit, punctuation mark, etc.) is contained within a rectangular area known as
a "matrix", which is divided into columns known as "trames" and which has a defined height and
width.
Example: 7 × 6 matrix - 16 × 12 matrix.
The first digit is the number of dots per trame and the second digit is the number of trames per
matrix.

1.2 Continuous deviated ink jet printing
The printer head is supplied with pressurized ink.
The ink arrives in a cannon (2) with a hole "nozzle" (3) through which the ink is ejected to form
ajet.
The ink jet is modulated by a piezo-electric resonator (1) to form calibrated and equidistant
droplets. The droplets not used for printing are recuperated in a gutter (6) to be reusedreused.
The droplets used for printing are polarized electrically by a charge electrode (4) and then
deflected from their initial path by two deflector plates (5) to produce the required symbol.
The deflection of a droplet depends on its polarization value.
The droplets are projected onto the item to be printed. A character is formed trame by trame; these
trames may be full, partial or empty. Moving the object perpendicularly to the deflection plane
enables the trames to be offset from each other.
