The size of an A3 poster is 297mm x 420mm

Create your artwork at the actual size of the finished product, or scaled proportionally.

The best resolution for images is 100dpi at full size.
(If you work at a scaled size you need to allow for the enlargement: SO if your artwork is at 25% size then the image resolution needs to be 400dpi.)

If possible, supply file with 3mm bleed and with crop marks. If this cannot be done, send it at exactly A3 with no crop marks.
DO NOT send artwork which floats vaguely in a larger area.
DO NOT include anything inside the trim area of the artwork that you do not want to be printed on the final poster.

Save a copy of your artwork to send to us. You can send:

PDF FILES - should be in pdf version 1.5 or higher, with all fonts embedded.
DO NOT SAVE DOWN TO PDF VERSION 1.3 - this is likely to reduce the quality of your artwork.

If you are using PHOTOSHOP, flatten your file and save it as a .TIF file, using LZW compression,
or as a .JPG using the HIGHEST QUALITY setting, and send this file.
