Your mechanical is the assembled elements of your document ready for the printers camera or the printshop photocopier. Methods of preparation vary but here are a few guidelines:
- A rigid board prevents bending that can cause your pasted elements to pop off or move on the page.
- The camera photographs light blue as white so use a blue pencil to sketch in lines to help position the elements.
- Paper or board with predrawn blue lines/grid can aid in alignment and placement of elements (available from graphic art supply companies).
Use a T-square, ruler, and triangle to ensure straight lines both when cutting apart printed elements and when assembling them on the mechanical.
- Use a razor or straight edge knife rather than scissors to ensure smooth straight cut edges.
- You can affix elements using wax, rubber cement, or adhesive spray. Whatever you use work carefully to avoid bubbles and be sure edges are firmly pressed in place.
- Keep your fingers clean and dry! (may seem obvious but one little smudge or bit of moisture can wreck your layout)
- Cut edges can sometimes show up in a negative or when photocopied. Use opaque liquid (sort of like typewriter correction fluid if you remember that stuff!) to paint cut edges.
- Consult your printer when preparing mechanicals for "camera ready" art. They may have specific requirements or suggestions for best results.
