It is recommended, that whenever possible, you supply your files in PDF format. This is the safest way to provide files in regards to layout and font issues. It is recommended all Word and Publisher files be supplied as a PDF. We unfortunately cannot guarantee there will not be problems as Word and Publisher documents are prone to have layout issues when opening and printing from different computers.
If your job is single sided then you simply supply a one-page PDF. If your job has two pages then provide a front and a back as a two-page PDF file, the first page of your PDF will be the front page and the second the back page. If you have a job with multiple kinds then please supply a PDF for each kind.
