Some suggestions for STScI staff
submitting material to be printed on the Photo/Imaging Labs Encad
wide-format ink-jet printer.
Preferably, use page layout or
illustration software such as FrameMaker, Adobe Illustrator, etc. to create
Microsoft PowerPoint is not
really intended to be a page layout or illustration program, though it is
relatively easy to learn and can suffice as a quick and dirty
method for poster production. Native PowerPoint format (.ppt) files will be
Make sure the document contains
a single page only. Use separate document files for separate
guidlines on science poster design are available from the American Physiological
Create your document at its intended
final size from the beginning by specifying the full page size in the layout
software. The maximum paper size is 40 inches (100cm) wide.
Keep in mind that what looks
fine on a letter-size (8.5 x 11 inch) page may lose quality or appear out
of proportion when reproduced much larger.
The recommended bitmap (raster)
format for imported images to preserve full detail and color is TIFF. This
applies to all imported images, including rasterized vector graphics.
Import charts and graphs using
original vector file formats (EPS, Postscript) whenever possible. (Yes, PowerPoint
can import EPS files.)
Any type of bitmap (raster)
image file format such as GIF, JPEG, or TIFF should be considered a solution
of last resort for the importing graphs and charts that contain curves and
If you need to use a bitmap
format, use TIFF if possible and make sure it is rendered at high enough resolution
to preserve fine detail in text, lines, etc. At least 300 pixels per inch
(ppi) at the final printed size is recommended.
Acrobat PDF (Portable Document
Format) is a good format for this purpose if it is available as output from
the layout software (Save As or Export). If you use
PowerPoint, we prefer to accept native .ppt files.
Send files to the Imaging Lab
via anonymous ftp to cauldron.stsci.edu
in the /world/inbox directory.
PDF and PowerPoint files may
be sent as an attachment to email.
Send email to Skip Westphal (email@example.com)
or John Bedke (firstname.lastname@example.org) telling
us that this has been done, what the file name is, what is required, and when
it is needed.
Turn-around time can range from
next day to two weeks depending on demand, lab workload, and unexpected technical
difficulties. Please do not wait until the last minute! Be
aware that each poster may take many hours to print and ideally at least a
day to dry for maximum ink durability.
Note that there will be specific
times when many people will want posters made; for AAS and ADASS meetings,
for example, which may increase turnaround time.
You can see some examples
on-line. Note that these are relatively simple posters intended to showcase
images rather than science results, but they might provide some ideas regarding
size, color, general layout etc. All were produced using Adobe Illustrator.
