Hi, I've found that exporting maps as an EPS (encapsulated postscript) file and then opening the EPS file in Adobe and re-saving as a PDF reduces file size quite a bit without losing quality and without having fonts change. Unfortunately this doesn't work if you are exporting a mapbook and it would still require exporting each map individually. Hopefully someone else has a less burdensome suggestion. Happy Friday.

Most maps are E-Sized, and they are 'complex'. I say complex in that they have many datasets, both raster and vector, fills, transparencies, complex polygons, millions (billions?) of nodes. These maps are beastly (but beautiful?). Part of our deliverable is PDFs and the distribution of the PDFs digitally. Right now this set comes in about 5GB in size. These PDFs were exports from ArcGIS Export command (using 350dpi, 1:3 resampling, RGB Colorspace, Compressed Vector Graphics, LZW Image compression). The maps range from about 35MB to 100MB. If I take these PDFs into Fully licensed Adobe Acrobat and just resave them, it seems I can gain another 30-40% reduction in file size, but doing this individually is less than appealing, I may be able to batch them through this. My question to the group is, are there any hints or tips on reducing file size when exporting to PDF from ArcGIS without losing TOO much quality in final output? Or have I maxed out my compression v. quality already? Am I doing something wrong, or right?
