Yes. When you are purchasing election material to be used to promote a candidate, a political party or a category of candidates in an election you have a legal duty to include on the artwork an imprint containing the name and address of the printer, the promoter of the material and any person on behalf of whom the material is being published (and who is not the promoter).
Our address for use on any imprint is: Publicity Print Marketing Ltd, 415b Warrington Road, Culcheth, Warrington, WA3 5SW. You can however elect to use your own details if you have an in-house print facility.
