When should I use A3 paper for printing?
On the other hand, you can also use A3 to spread details about an upcoming event to your target market. This can be in the form of flyers coupled with a minimalist design and few but bolder texts for crisp and concise messages. You can also simply hang them on walls and bulletin boards without being obstructive.
Another way you can use the A3 format is when you are trying to make a presentation which contains various large tables or diagrams. In fact, you can distribute this paper format around the table for added convenience to your attendees. By using this paper size, you will be able to demonstrate your ideas much clearer to your target audience.
Printing resolution for A3
The resolution needed to print A3 size images with the best quality is 297 x 420 mm at 300 ppi (pixels per inch). Please do note that you would still have to add a bleed of 3 mm on all sides of your design, to ensure you receive your printed products exactly as you expected. InDesign has a tool with which you can easily add bleed to your designs, but in Photoshop you will have to add bleed manually. Not sure if you added bleed the right way?
