I need a 1000 dpi tif file in a size of appr. 10 to 10 cm for applied 
animal behaviour science:

images to one of the following formats (Note the resolution requirements 
for line drawings, halftones, and
line/halftone combinations given below.):
EPS: Vector drawings. Embed the font or save the text as "graphics".
TIFF: Colour or greyscale photographs (halftones): always use a minimum 
of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (colour or greyscale): a 
minimum of 500 dpi is required.
DOC, XLS or PPT: If your electronic artwork is created in any of these 
Microsoft Office applications please
supply "as is".

I tired the Postscript file but the file is double heigh as width i do 
not know why.
The problem was already discussed in the tread: [R] High resolution plots

I have to send the images possibly yesterday and I am looking fo a 
suitable solution since two months now.
I tired gsview with converting to all possible Tiff formats but the 
images appear not in color and in a strange black and white way
Some readers are able to read it  (Windows Image view) other not and I 
do not know which reader the journal will use :-(
And the ylab is too small ...

Ok there is a second description for the file format :-(

there are pdf formats welcome but with defined conditions:

Maybe anybody could give me a hint to get the files in the recommendet 
format.
I will ask them immediately which whether the pdf is allowed or not, 
becaus they have two different instruction sites :-(
