The environment is not in its best conditions. Every action taken and every kind of material used may take its toll, and so, every little activity counts, even the printing of paper. Instead of printing your graphics for feedback, why not use this free mockup provided by Matt Devries?
This tool presents a newspaper from a perspective shot which you can use to display your ads and images on a full page. The highly realistic easily editable scene with its 5472 x 3648 pixels resolution (300 dpi) comes in PSD format. This means that you can insert your graphics via smart object insertion method and edit using the color-coded layers to save yourself some time; however, you do need a CS4 Adobe Photoshop version or a higher one. In addition to the mockup itself, the download file includes a text edit instructions guide.
