Digital printing
Digital printing
processes include electro-photographic and inkjet printing.
Electro-photographic printing
Electro-photographic printing
This involves the depositing of toner into the paper or card. Dry or liquid toners can be used but they are fixed by heat and absorption which explains why paper comes out of printers warm
Inkjet printing
Inkjet printing
This involves spraying electrostatically charged ink droplets directly onto the paper relying on absorption to fix the inks.
Screen Printing
Screen Printing
Screen printing has a number of different applications where inks or other materials need to be printed onto a flat surface such as:
transfer of designs onto paper and fabrics.
transfer of designs onto ceramics.
printed circuits for electronics products.
the process was originally called silkscreen printing as ink was forced through a template via a silk screen and squeegee. Nowadays it is much more complex and can print onto curved surfaces.
