Hi

I have a problem when I try to make a poster from files with 300dpi.
During the pdf creating it gives me a runtime error.
I don't have this problem when I scale down to 200dpi, but I don't want to lose some quality in my picture when I print.
I already tried different formats (pdf, tiff, psd) but none worked on 300dpi.
Is there someone who can help me?

Thanks in advance !
