Illustrator CS6, Windows 7, compression

i have been saving files without compression in adobe illustrator, , many of them contain photos. large files, printed @ 2400 dpi. affect print output if files compressed when saved? thanks.

ok.

 

compression produce smaller illustrator files not affect output.

 

illustrator files, default, saved 1 file in 2 distinct formats, 1 native illustrator data , 1 pdf. when edit file in illustrator native illustrator part of file used , pdf portion ignored. new pdf created when file saved. compression affects part of file, lossless (unlike jpg compression). compression has little effects on file sizes since acts on vector data, smaller raster data , acts on native illustrator data smaller pdf data. small vector-only illustrator files see benefit, small begin with. still, ignore compression setting, means leave on since default.

 

here simple vector file saved compression on , off…

 

when view illustrator file in bridge, windows explorer, indesign, or photoshop accessing pdf portion of file. contains placed , embedded raster art (like placed tiffs jpgs, , psd files) @ full resolution, vector art vectors possible (vectors have infinite resolution) , rasterized vectors , vector effects @ resolution specified under effect > document raster effect settings.

 

greater space saving can achieved making sure placed images linked, not embedded, raster effects (shadows, blurs, , effect listed under photoshop effects) minimized. if not need view or output illustrator file in program can save create pdf compatible file option turned off…

i save seen files drop few hundred megabytes 1 megabyte. really. won’t able view files in program or place in indesign or photoshop. if don’t need anyway, space saving can significant. time saving more worthwhile, since saved take fraction of second, not as minute. means save more since wait every save negligible.
