It’s true that our first foray into poster printing was the purchase of a large format printer to print posters for nightclubs, hotels, venues and pretty much business connected with the hospitality industry. Since that time we’ve become experts in all manner of large format digital printing. From indoor posters, to roller banners, canvas prints, waterproof posters and forecourt overbags, we are fortunate to have gained an unmatched understanding of what works and what doesn’t work for businesses like yours.

Today we’re going back to basics on poster printing. As a company we appreciate that many of our customers don’t order print regularly. With that in mind, we’ve put together some of the most frequently asked questions relating to post printing. So if you want to know about poster sizes, bleed, CMYK or RGB colours and pretty much everything else we know about posters, please continue to read on!

An A0 poster is sized at 841mm x 1189mm in size (portrait). Alternatively the poster may be landscape and this would be designated by an 1189mm x 841mm sizing. When designing an A0 poster, please add 3mm bleed all round for print finishing.

What size is an Adshel Poster?

The size of poster required for Adshels is 1200mm x 1800mm.
When supplying your artwork for print, please ensure you add 3mm bleed on all sides. It is also common practice to leave a safe zone of at least 3mm on the inside of your finished artwork size.

Setting up your posters for printing

You want high quality printing and so do we! To get the best from your artwork, we suggest you create your artwork with the following elements. This will ensure your poster printing is printed and finished to the absolute highest standard possible.

What resolution should my poster be?

When setting up your poster artwork for print, please set the resolution to 300dpi. This will ensure high quality “hd” printing.

The exception to this rule is 100-150dpi resolution for billboard posters due to the distance they are to be viewed at.

How much bleed do I need to add to a poster design?

When designing a poster for print, please add 3mm bleed to each side of the design.
This can be automatically added within Indesign & Illustrator. However in other programmes you may need to manually add this. To do so add 6mm to the overall width and height of the design.
