TIPS FOR ELECTRONIC FILE PREPARATION
If you’re creating an electronic file that will be transmitted
to Dual Graphics for publication, use the following tips when
For a brochure, catalog, or any text type reading material,
use a page layout program such as QuarkXpress, Adobe Pagemaker,
or Adobe InDesign. Avoid creating text pages in Adobe Illustrator,
Macromedia Freehand, or any other drawing or photo-imaging
application. Avoid using Microsoft Word or Publisher. These
programs have many output problems, such as the inability
to produce CYMK separations and the low-resolution output
Make your document/page layout the exact size that you want
your printed piece to be. For example, if your piece is a
20 x 24 inch poster, make your document size 20 x 24. Do not
make the document bigger and then add manual crop marks.
We strongly recommend not using TrueType fonts when creating
your piece. Instead, use Postscript fonts, formally called
Adobe fonts. TrueType fonts not only create problems in type
wrap around, especially when cross-platforming (going from
PC to Mac), they also create problems when ripping to a high-resolution
Don’t apply style commands (such as bold or italic)
to a typeface. Instead, choose the bold or italic version
of the font directly from the font menu. When you stylize
your fonts in the font pallet, it may print correctly on a
laser printer, but sometimes it will not output correctly
to a high-end image setter.
Make sure the pixels-per-inch image size in your Photoshop
files are twice the target line screen. For example, if you
want to print with a 175-line screen, make the pixels-per-inch
350 at reproduction size. (Pixels-per-inch is the same as
dots-per-inch.) However, bitmapped images or line drawings
should be 600 dpi.
The rule of thumb in creating gradients or blends is to create
them in Adobe Photoshop. Create them on a transparent layer,
and before you flatten the layer, add four pixels of noise
with the noise filter. Gradients created in QuarkXpress, Illustrator,
or Freehand will result in banding if they are any longer
than a few inches.
Do not enlarge a placed Photoshop, or pixel-based file, in
your page layout program by more than 20 percent, as this
reduces the pixels-per-inch.
Bleeds in your page layout file should be .125 (or 1/8) inch.
Convert all RGB colors to CMYK, especially in photographic
Make sure that your Pantone color is correctly specified as
a process color (screen mix) or as a spot color in your page-layout
It is imperative that you provide us with the fonts that you
have used. You must send the files containing both the screen
(bitmapped) fonts and printer (outline) fonts.
Provide us with the original or parent Freehand file along
with your EPS file.
Provide us with all linked graphics, including ones that are
placed in Illustrator or Freehand files.
Make laser prints of everything and indicate color breaks.
Please include the latest update; make sure that the laser
print matches the file you give us. If the laser print is
reduced, please indicate this on the proof. If you are uploading
your files to our FTP site, please fax your lasers or let
us know and we’ll pick them up. It is always a good
idea to include a good quality laser or plotter proof with
your files. This lets us see what you intend your project
to look like. This will assist us in giving you the best possible
result, while reducing the chance of errors, omissions,
costly changes, and time to produce your proofs.
