Adshel – 6 sheet poster printing

Adshel advertising (often misspelt as Adshell) is one of the most common forms of outdoor advertising in the UK. Adshel posters are more commonly known as 6 sheet posters and are what most people would refer to as bus stop posters. It is easy to understand the attraction to this kind of marketing, especially by the big brands. A typical national six sheet poster campaign can be seen by 70% of the UK population in only a 2 week period. That is approximately 43.5 million people viewing the advert and most of those people will see the 6 sheet adverts time and time again over the duration of the OOH campaign (OOH stands for Out Of Home advertising). Of course they are also used on a smaller scale to promote local events by cinema’s, theaters, night clubs and alike too.

Adshel poster advertising exposure

All kinds of billboard advertising will gain great exposure for your brand but as mentioned above, a national Adshel advertising campaign will reach a huge amount of the population with a short time frame and repeatedly advertise to many of them on a daily basis. They can be seen during the day but also at night as they are displayed in illuminated display cases – most usually at bus stops around city centers and suburbs.Whilst other billboard campaign are often highlighted with lighting it’s not quite the same as the illuminated displays. For this reason, Adshell six sheets are one of the most effective street advertising mediums.

Printing Adshel posters

Adshel poster printing is fairly specialised due to its large format. Whilst for smaller campaigns the 6 sheet posters printing can be done digitally, for larger campaigns it simply has to be done on a large format litho press. There are a number of digital machines capable of printing up to 6 sheet size but only a handful of litho presses in the country. The other requirement for printing 6 sheet posters, like many outdoor posters, is that they must be printed with UV resistant inks. This is to make sure that they don’t fade after constant exposure to the sunlight. Big Litho can supply both short run digital 6 sheet posters and longer run adshel posters. If you are looking to start an Adshel campaign then it’s definitely worth having a chat about our adshel printing service.

6 sheet poster size and resolution for printing

6 sheet poster printingThere are two main sizes for 6 sheet posters and like any large format poster printing it is important that the artwork is set correctly. The most common size is the Adhsel size but JCDecaux (Who own a great deal of the UK’s illuminated advertising boxes) have their own JCD 6 sheet size too. Below are the two 6 sheet size formats:

  • Adshel size -1800 x 1200mm
  • JCD 6 sheet size – 1750 x 1185mm

If you are running a campaign to run 6 sheet posters in JCDecaux boxes and other advertisers boxes you will need to know quantities for each and adjust the artwork accordingly. If you are running a larger campaign that requires litho printing you can save some  money by ensuring that the copy fits within the viewable area for both and then having the posters for the JCDecaux boxes trimmed to the smaller size without losing any of the advert. Big Litho can help with adjusting your artwork accordingly.

As for the image resolution this is a disputed point depending on who you speak to. For most handheld print such as brochures and leaflets you would be advised to stick to 300dpi as a minimum and the same would be said about anything viewed from 1 meter away or less.Bus stop posters are viewed from a varying range of distances with some people passing by in a car or walking at the opposite side of the road and others being very close stood by the bus stop itself. However due to the size of the posters (taller than most men), those that ares stood that close will most likely not be the ones captivated by the advert as one would ideally need to stand back to view the full poster and it’s message. It’s also very unlikely that many images can be obtained in 300dpi such a large size. Ideally we would recommend having your images set to 150dpi where ever possible but we have printed 6 sheets as low as 72dpi and they have looked perfectly acceptable to most. What is often more important than the actual resolution is the quality of the original image that is being used.

    JCDecaux offer spots all over the UK for adshel advertising. I think they are one of the largest but if you are thinking about running an international advertising campaign then is it best to speak directly with the owners of the billboard stands or is it best to go through an agency that works with them all?

    Hi John. Thanks for dropping by. I’m not too sure about this as we don’t get involved in the adhsel advertising placements, we just supply the six sheet posters for installing. I would start by speaking with JCDecaux and Clear Channel who also have a high number of Adshel and billboard sites in the UK. Links below.

    There are other agencies, some more localised to towns and cities but if it’s a national campaign you are rolling out then I’d start by speaking with these two to get some idea’s and costs together.

    Don;t forget to get in touch with us for your printing as we typically save a lot of money over the agency costs for adshell printing.
