When we proof data, we make sure the front and back sides of the data are printed so that the top of both pages share the same edge. This is called ‘top to top’ orientation.
If you are designing for a two sided, flat product, the orientation of your artwork will determine how the front and back sides will be printed in relation to each other.
Please note: with diamond shaped artwork, you must indicate which is the top and bottom of the design. Square artwork without proper orientation labelling will not advance to the production stage until you can confirm it.
As shown in Figure 1, if you specify top and bottom when the direction of the design are both facing the same way, the front and back sides will not match when printing.
Figure 2 shows the correct way to set the design up, and the correct way to assign the top and bottom designation.
