Preserved Topic: Is this really true? (Photoshop/Illustrator thing) (Page 1 of 1)

Hi there

A guy claims that when you save your work with clipping paths as EPS or TIFF in Photoshop the vector information is discarded and the whole document is compressed into "pixeldata" thus making the filesize much bigger. He states that if you were to save as EPS or TIFF in Illustrator the output would be smaller and still be in "vector".
Is this really true?

cheers

"As if..."

If you compare apples with apples, an EPS is an EPS.

If you compare apples with oranges, vector data made in Illustrator could be smaller than pixel data made in Photoshop.

If you compare apples with Elephants, then yes everything gets smushed into pixeldata and comes out as a .png.



Now - to stop being a jerk, I guess maybe your friend is referring to Photoshop 6's vector-based shape and type layers. These aren't the same as traditional clipping paths. Jeni knows how to save photoshop 6 files to preserve their vector properties - ask her about how much an apple made in Photoshop weighs compared with an apple made in Illustrator.

Thanks Steve. I know the term "pixeldata" is confusing...but hell thats his exact words.

Jeniiii I need to know about apples

Cheers

In case you didn't get my email, here's how you do it...
Don't rasterize your vector (type, shapes) layers...
When you're ready to save the file to go to print:
DO NOT FLATTEN IMAGE! Go to save as and select eps...You'll get a dialog box, note the "preserve vector layers" checkbox and make sure that it's selected. Voila. Finito.
Something else to note: If you try to reopen that EPS in PS it will then rasterize your vectors. But you can be sure that they're otherwise crisp as they can be. To test this, make a file that's like 40 ppi, create some type, do as described above and then place it into another program. Then print it.
As far as file sizes go....hmmm never tried one vs. the other...just try it yourself I guess...

So far as I know, TIFF doesn't support layers of any sort, vector or otherwise, so seems to me this (very valuable) technique is limited to EPS.

Good to know.
