I have posted a few other topics related to problems with image files in PDF output from plotmaker. I have since been playing with the image compression settings in the Amyuni driver and this has helped some of the issues I was having with our plotting service bureau. Changing these settings can have a large effect on file size, and I was wondering what others have concluded about image compression. We have currently switched to a jpg compression, but a a compression level of 5 (approx 25 % larger file than default compression), the image quality is lower than we would like. We will sacrifice file size for increased quality, but I was wondering if others have already gone down this path and have any suggestions. Thanks in advance.
