Specifying the emulsion and image exposure
Depending on the type of printing press used and how information is transferred from the
film to the printing plates, you may need to give your service provider film negatives or
positives, with emulsion side up or down. Emulsion refers to the photosensitive layer on a
piece of film or paper. Typically, service providers require negative film in the United
States and positive film in Europe and Japan. Check with your service provider to
determine which emulsion direction they prefer.
To tell whether you are looking at the emulsion side or the non-emulsion side (also
referred to as the base), examine the final film under a good light. One side appears
shinier than the other. The dull side is the emulsion side; the shiny side is the base.
Film options A. Positive image B. Negative C. Negative with emulsion side down
Important: The emulsion and image exposure settings override any conflicting settings in
the printer driver. Always specify print settings using the Advanced Print Setup dialog
box.
To specify emulsion:
1. Select the Output panel on the left side of the Advanced Print Setup dialog box.
2. For Color, choose a separation option.
3. For Flip, select one of the following options:
None (the default) to make no changes to the orientation of the imageable area. Type that
is in the image is readable (that is, "right reading") when the photosensitive layer is facing
you.
Horizontal to mirror the imageable area across a vertical axis so that it is "wrong reading."
Vertical to mirror the imageable area across a horizontal axis so that it is upside down.
Horizontal And Vertical to mirror the imageable area across the horizontal and vertical
axes so that it is wrong reading. Type is readable when the photosensitive layer is facing
away from you. Images printed on film are often printed Horizontal And Vertical.
To specify the image exposure:
1. Select the Output panel on the left side of the Advanced Print Setup dialog box.
2. For Color, choose a separation option.
3. Select or deselect the Negative option.
