What is Offset Litho?
Offset Litho is method of printing at an industrial scale in which inks are transferred onto aluminum plates to make an impression.
As Lithographic & Digital printers we are well aware of the confusion that can occur when talking about printing your marketing brochures, business cards, flyers and leaflets. There are so many choices in paper weights, paper finish and paper colours – there are also different printing processes.
How do you know which out of litho and digital printing is best for you and your business?
While there are advantages and disadvantages to both, we have tried to explain the difference between the two most common processes below.
Digital Printing vs. Lithographic Printing
Digital printing is the reproduction of digital images on physical surface, such as paper or photographic paper, cloth, plastic, etc.
Litho printing is a technique where the inked image is transferred from a metal plate to a rubber blanket, Typically, printing plates are attached to a cylinder in the press. Ink is applied to the plate’s image area and transferred directly to the paper.
Digital can be differentiated from litho or offset printing in many ways, such as:
Every impression made onto the paper can be different, as opposed to making several hundred or thousand impressions of the same thing from one set of plates, as in traditional methods. The ink or toner does not absorb into the paper, as does conventional Ink, but forms a layer on the surface. It generally requires less waste in terms of chemicals used and paper wasted in set up.
Digital is a excellent solution for quick turnaround, or small print runs!!
Offset printing is most commonly used for high volume printing as its image quality is much higher and more consistent than that of the digital press.
