When should I use A1 paper for printing?

A1 is a paper size that is commonly used for technical drawings such as architecture and engineering drafts. It is also the best choice when doing flip charts and posters as they have a large enough space for you to put all the necessary design and information for your target market.

For example, we have A1 paper size standard posters that are available in three different kinds of material. We have our standard material which is ideal for indoor marketing as it is not at any risk of being affected by weather conditions.

We also offer colour blocking material which is great for billboards or poster walls as you can incorporate bold colours for a striking impression that will surely get your audience’s attention. Finally, our waterproof posters make for the best material outdoors as these can resist wet climate conditions for lasting performance.

You can also use the A1 poster size to promote your brand’s top-grossing product and services. This also makes a great alternative when marketing in an area with a high amount of traffic such as malls, theatres, and conferences. Go for our A1 poster size the next time you order your promotional item with us for an efficient outdoor marketing campaign.

Printing resolution for A1

When printing an image of A1 format, the print resolution has to be 594 x 841 mm at 300 ppi (pixels per inch). Your design also has to include bleed, to make sure that there will be no white borders around the printed products you ordered. InDesign has a tool that allows you to add bleed easily, but in Photoshop you will have to add it manually. A bleed of 3 mm on all sides would be sufficient. Not sure if you included bleed the right way? Check our free design templates for the product you're interested in.
