Inkjet Printing
The print is formed of dots as a result of spraying ink from the printer nozzle onto the print-receiving surface.
Characteristic features of the print:
- images are formed by randomly spread ink blots;
- ink dots form something like a halo along the contours of letters and digits;
- color halftone images do not have a regular structure.
