Ideally, you should speak with your printer before you even open your
drawing or layout program, or before scanning any artwork or photos.
You will get better results, save time, and possibly save money.
Check with your printer for their prepress
specs. These
specifications will let you know your printer’s exact
requirements for file submission and accepted file types
and how to deliver them. Familiarity with prepress specs
will help you in setting up your file, designing the project
correctly, and delivering it to your printer the way that
works best for them. Following your printer’s
prepress specifications will ensure the accuracy of your print
job, avoiding errors and extra cost for corrections.
Application file
This is the actual digital
file that you created with your professional graphics application.
Before you submit an application file:
- Be sure your printer has the same software and a compatible
version.
- Ensure that the printer can handle files from your platform.
- Note: Few printers accept Microsoft Publisher (.pub)
files or files from anything other than the Adobe® programs,
QuarkXPress®, Corel®,
and other major 'professional' applications. This
can vary by region.
- If your application file is not acceptable
you may want to consider submitting
a PostScript® (or
PDF) file for output.
Fonts
Even when you use common, classic typefaces you'll need
to send the copies of the actual font files that your document
contains. Fonts can vary from vendor to vendor; differences
exist between the TrueType and Type
1 versions of fonts. If you don't supply your own fonts,
another version of the font may be substituted. This might work,
or it might result in subtle or obvious differences in your document.
- Send both screen and printer fonts (for Type 1 fonts).
- If you have embedded EPS
files that include text not
converted to curves, send the fonts for those images as
well.
- Avoid mixing TrueType and Type
1 fonts in the same file.
- Send the same version of the font (that is, if you used
TrueType fonts but send the Type 1 version of that typeface,
you may see errors).
- To avoid having to send font files, embed all your fonts
or convert text to curves.
However, this isn't always possible or advisable. Check
with your printer first.
Graphics
Send
copies of all your images used in your document. If you've practiced
good file size management, then most of your graphics are linked,
not embedded in your document. Your printer may need to have
access to those original graphics, otherwise your application
file may have only low-quality preview images in the file or
no graphic at all.
- Use EPS and TIFF images. If you must use other formats, check
with your printer.
- Convert RGB images to CMYK.
- Save graphics in uncompressed formats (TIFF/EPS).
- Don't change graphics file names unless you first re-link them
in your application file.
In some instances, your printer may want you also to send original
format graphics (Freehand, Illustrator, Photoshop files) in addition
to the placed EPS/TIFF images in your page layout application for troubleshooting
purposes.
To ensure that you include all fonts and graphics needed for your
output, it is a good idea to use the collection capabilities of your
program or third-party programs for Preflight Collection.
