Offset Printing:
* Ink: Oil-based or water-based ink is used in offset printing. The ink is transferred from a plate to a rubber blanket, then to the paper.
Digital Printing:
* Toner: Digital printing uses toner powder that is fused to the paper with heat. While not a liquid, toner is a fine powder that is suspended in a carrier fluid.
* Inkjet: Inkjet printers use liquid ink cartridges that are sprayed onto the paper. The ink is water-based, pigment-based, or dye-based depending on the printer.
Screen Printing:
* Ink: Screen printing uses thick, opaque ink that is pushed through a screen onto the paper. The ink can be oil-based, water-based, plastisol, or other types.
Letterpress Printing:
* Ink: Letterpress uses oil-based ink that is applied to raised type and then pressed into the paper.
Flexographic Printing:
* Ink: Flexographic printing uses water-based or solvent-based ink that is applied to a flexible printing plate. The ink is then transferred to the paper or other substrate.
Other:
* Gravure Printing: uses a gravure cylinder that is engraved with the image. The ink is applied to the cylinder and then transferred to the paper.
* Relief Printing: uses a raised printing plate to create an impression on the paper.
* Intaglio Printing: uses an etched or engraved plate to create a raised image on the paper.
