Who’s Got The Power? Digital Printing versus Litho Printing
When considering your upcoming print project, there are a range of factors to bear in mind, not least whether to use Litho or Digital production techniques. This topic can sometimes feel like a bit of a minefield (that’s why we’re here to help guide you!) but ultimately it comes down to a few main considerations. Before we take a look at these, it’s important to understand the difference between the two methods and when/why each technique would be employed.
SO WHAT’S THE DIFFERENCE?
In most simple terms, the main difference between the two processes is that Litho relies on the transfer of wet ink via an aluminium printing plate with an image on it; meanwhile Digital uses dry toner which is fused directly on to the sheet using heat. Whilst each has its benefits, it should understood that there is no one ‘BETTER’ method as it ultimately comes down to a range of situational factors including quantity, timescales, budget etc.
Here at A3, we are extremely proud of the quality we are able to achieve both lithographically and digitally with top-of-the range machinery in the way of a Heidelberg Speedmaster SM74X and two Heidelberg Versafires. Our machines are operated and maintained to the highest standards by our team of expert print minders. In fact, the quality and colour is so comparable that it’s often difficult to tell the difference to the naked eye… as was case in hand with these two Hobbs Lookbooks.

What we consider when deciding Litho Printing versus Digital Printing
For shorter run lengths, Digital printing is definitely the most suitable option as there are no start-up/make ready requirements unlike those involved with Litho printing. Where higher volumes are demanded, Litho printing really comes to the forefront as you can really make the most of economies of scale, observing the unit price going down whilst quantity goes up.
Personalisation (variable data)
Where personalised print is concerned, Digital wins hands down. This is because variable content is prepared in digital format (typically as a PDF file) and does not require unique impressions to be made on a Litho plate which would be extremely costly. Personalising print using this method is quick, easy and cost effective.
When it comes to out-and-out machine speed, our Speedmaster is the hands down winner (as the name suggests)! Printing up to a whopping 13,000 SRA2 (single sided) sheets per hour, this is over three times the capability of our Digital presses which print approximately 4,200 SRA3 sheets in the same timeframe.
Type of material/substrate
Although the potential of our Digital is quite extensive, in general, our Litho press successfully prints on a much wider choice of substrates and is also able to accommodate higher gsm stocks. Our Versafires will run a range of coated and uncoated stocks up to 400gsm, whilst our Speedmaster can achieve the same on 450gsm material.
When it comes to printing, size does matter! Our Versafires are able to run a maximum sheet size of 700mm x 330mm which produces a 6pp A4. The Speedmaster, however, accommodates an impressive 740mm x 530mm sheet and is therefore less limited in the finish size it’s able to produce.
Whilst both production methods rely on the use of four fundamental colours – Cyan, Magenta, Yellow, Black – known as the CMYK colour system, Litho has the added unit giving the option to print a seal, spot or pantone colour. Spot or Pantone colours are used by companies to colour brand logos with precision, right down to the exact hue. This extends creative options for print designers and encompasses a range of unique ink blends such as fluorescent and metallic pantones.
If you are up against pressing deadlines and looking to achieve a speedy turnaround on your print project, then Digital is definitely the way to go. Not only does digital toner dry instantly, print files can be ready-to-go at the click of the button and without the need to make plates and set-up. Additionally, our digital machines have the capability to print sheets in collated sequence order which saves time when it comes to finishing. This all makes for an efficient process from start to finish!
Compatibility with special finishes
Both print methods achieve successful outcomes when it comes to special finishes such as foil, embossing, debossing and lamination but our digital press currently has limitations achieving Spot UV Varnish. Our newest Digital Versafire – we like to call Victoria – has a built in booklet maker which eliminates touchpoints and enables us to produce printed and finished booklets in one pass.
