There is so much that goes on behind the scenes for designing an ad before the final product, that you see as the viewer. One of those processes is design layout. The process may be slightly different for each company. Approvals for each step in the process are required before moving on to the next and the first is a thumbnail sketch. This is a small and rough drawing that artists use to visualize different layout approaches. The second phase is the rough layout. This is the to scale for the ad where illustrations, text and photos are sketched in. The next step is comprehensive with an elaborate layout where all visuals are final. Fourth, the dummy. This is done with color markers and or/computer proofs. This will look like the finished ad. Paste-up comes next where text and visuals are placed in their exact positions to reproduced in printing. The last step is final approval. This is done by the copywriter and director. Although all of the steps are a required part of the process how do you know what layout to use for your ad?
