What are the differences Between Digital Printing and offset?
What is digital printing exactly?
Digital printing allows you to print directly on paper from digital data available on a computer. This highly responsive printing technique allows for faster printing of your communication documents.
How? Remember how offset printing works:
When printing in offset, printing is not done directly on the paper. It goes through a cylinder covered with a sheet of rubber, from which the ink is transferred to the paper.
With digital printing, the production is done directly on a printer and the documents are formatted by computer processing. So we go directly from the computer to the printer.
The difference between offset printing and digital printing, therefore, lies in the intermediate steps to the final printing of the document. Digital printing, therefore, shortens production times by eliminating certain steps between document design and offset printing.
A different final rendering
In digital printing, inks are usually powdered, and baked on the surface of the paper, while in liquid form for offset, printing. On the finished document, digital printing gives a glossy visual on all types of paper used. In offset, the inks are liquid and absorbed in part by the paper. So there is some difference in colour for the same project depending on the finish and paper used.
Documents printed with digital printing generally have a maximum size of 30 cm x 45 cm. The ink is more surface, it is more fragile to friction and folding. Nevertheless, many documents can be printed digitally: pads, brochures, business cards etc.
