hi everyone,
i have one of those large format plotters that can print up to A1 size
sheets. last week a friend of mine asked me to plot for her several an
image file on a large poster size - A1 in height and 2 meters in
length.
the original picture is in tiff format and was made at a resolution of
400 dpi.
when i tried to plot it in the required poster size the resulting image
size just caused my computer to hang. it was something in the size of
1.2 GB!!! is that correct? this was the file size that i see in the
photoshop information tab.
i have ample disk drive space for the scratch disk but my computer just
hangs evertime i try to enlarge it to the needed size...

what am i doing wrong?
or how do those advertisers print those large canvass ads?
thanks in advance...

Use a lower resolution - 100 pixels per inch should be plenty for such a
large poster. Verify that this is enough by plotting a small section of the
image first, and increase the resolution only if necessary.

IF the file has more than one layer, flatten it first, then image size with
resample UNCLICKED
if the resolution is way too low you may have to up it a bit but unlikely
you need 400 for large poster, low 200's is usually fine.

You didn't mention your platform (Win ?? , MAC, Linux, ...).
What were the spoolfile settings?
Have you tried Qimage (http://www.ddisoftware.com/qimage/)?

hi to everyone,
thanks for replying.

my specs are P4 2.8 winXP Pro using both PS6 (and CS Trial) at 1GB Ram,
hd space ~80 GB Free.

if i resample it to 200dpi would that be course?

someone told me that i may need a RIP software but the PosterJet
version is a bit expensive. we are only using our plotters for CAD
drawings so we have not encountered this problem before.

do i really need a rip? any version that is free?
thanks.
