Digital printing has a process that allows for on-demand printing, short turnaround, and even a modification of the image (variable data) with each impression. The main difference between digital and offset printing is that no printing plates are needed which creates a quicker turnaround time. The quality is fantastic but not as true to color as what offset printing can provide. This option is a great alternative for short turnaround and small quantity jobs.
Process: In many of the processes the ink or toner does not permeate the substrate, as does conventional ink, but forms a thin layer on the surface and may in some systems be additionally adhered to the substrate by using a fuser fluid with heat process (toner) or UV curing process (ink).
Advantages of Digital
Shorter turnaround.
Every print is the same. More accurate counts, less waste and fewer variations, due to not having to balance ink and water during press run.
Cheaper low volume printing. While the unit cost of each piece may be higher than with offset printing, when setup costs are included digital printing provides lower per unit costs for very small print runs.
Variable Data Printing is a form of customizable digital printing. Using information from a database or external file, text and graphics can be changed on each piece without stopping or slowing down the press. For example, personalized letters can be printed with a different name and address on each letter. Variable data printing is used primarily for direct marketing, customer relationship development and advertising.
