Offset Printing, also known as Lithography; is best defined quite literally as writing with stones. The image to be printed will be engraved on a flat plate and then inked when it comes into contact with paper. The plate will then be flushed with water so ink will only be adhered to the engraved areas of the plate, as the lithographic process of the repulsion of oil and water keeps the non-printing areas ink free.
Offset Printing is able to print on sizes larger than A3, and is recommended for larger quantities (more than 1000) to be economical. Sharp and clean high quality print can be ensured and little maintainence is required if this type of print is chosen. As such, Offset Printing is also one of the most common methods of printing today. We recommend Offset Printing if your image contains fine lines, photographs, screens or tints.
Digital Printing refers to high speed laser printing, often utilizing a state-of-the-art digital colour copier using a single source of concentrated light to expose the image on to photosensitive material. Electrically charged toner will then be attracted to the image and the toner particles are then transferred to paper when in contact with heat or pressure. It is a very fast method of printing as the print is dried instantly.
Digital Print is typically for low print run, hence recommended for smaller quantities and can only print up to a maximum of A3 size. It prints directly from digital files and no film is involved at all. Compared to Offset Printing, the content can be more easily changed, translating to lower wastage and personalization. There is also a significantly shorter lead time. Digital Prints work well on paper or canvas.
