Offset & Litho Printing

Producing fantastic print work for over 25 years

We’ve been producing fantastic print work from our West Midlands base for over 25 years. Whilst technologies have changed and digital print has introduced another option to the market, offset printing (also known as litho printing) still delivers fantastic benefits.
Whatever you want to print; from packaging to prospectuses, from folders to promotional literature; litho printing provides the best value for high volume quantities and high end finishes. It has the flexibility and capacity to produce large volume should your print job require it.

Offset printing. What’s that then? Isn’t everything digital now?

Also known as litho printing, offset printing is a technique of mass printing in which images on metal plating are transferred to a temporary medium and then placed on its actual print medium. The main advantage of offset printing is that it produces high-quality images consistently. Offset printing has made it possible for us to offer a multitude of products, from limited edition prints to posters, business cards and much, much more. The image is etched on a metal plate which is put on the printing press. These plates are then covered in an oil-based ink and the inked plate is applied to the paper it’s printed on.

How offset printing works

STAGE 1

The first cylinder used in the offset printing process is the ‘plate’ cylinder. This thin cylinder has a plastic or aluminium plate around it. Each plate is customised according to the text and images to be printed onto the paper. The plate cylinder has been pre-treated to have the images attract ink and repel water. When the plate cylinder spins, it will make contact with rollers that apply the ink and water.

STAGE 2

The second cylinder is the ‘offset blanket’ cylinder. This cylinder has a rubber blanket around it and turns in the opposite direction to the plate cylinder. When both cylinders roll against each other, water is squeezed away and ink is transferred onto the rubber blanket. This creates a mirror image of the ink design.

STAGE 3

The third cylinder in the offset lithography process is called the ‘impression’ cylinder. Made of clean steel, it turns in the opposite direction to the blanket cylinder. The impression cylinder transfers the ink as it presses paper against the rubber blanket.

Cost Effective, High-Quality Offset Printing Solutions

In terms of cost, a significant area of cost sits with creation of the plates and making ready the job. Once this is done the cost per copy is cheaper for offset printing rather than digital printing on longer printing runs. The resulting image will be high quality and uniform, even during a long print run.

The Benefits of Offset Printing

Offset printing presses are fast and efficient – they can print up to 18,000 sheets per hour. With each sheet containing up to 48 pages of A4 or letter-sized content. A typical offset press can print eight pages in one sheet – which translates to around 120,000 pages per hour!

In commercial offset printing, the more you print, the less you pay. After the initial cost during setup, you will only spend a few pence per sheet for the paper and ink. If you need to print flyers, brochures, booklets, newsletters, and other materials in large volumes, the office printer or even a professional digital printer is not the way to go. They are less efficient and more costly.

If you need to print a large batch quickly, then offset printing can make it happen. Once the initial design has been transferred to the plate cylinder, printing onto paper only takes a matter of seconds.

Offset printing produces sharp typefaces, fine details, and images with rich, accurate colours. An ordinary printer won’t be able to match this high level of quality. But Denote Print can.
