Commercial printing is a little more complicated than just selecting “File” –> “Print” from your Word, Excel or Publisher file at home. Commercial printing generally involves printing multiple copies of an artwork design on a large sheet of paper or card stock, which is then cut down with a guillotine to the correct final size.
Due to all the specifications required in generating a high quality “print-ready” file, most graphic designers and commercial printers use professional graphics software like Adobe (including InDesign, Illustrator, Photoshop). Therefore, a Word, Excel or Publisher file will not be accepted as a print-ready file.
