Question

How do I create a .eps file at 300 dpi?

I need to create a 300 dpi Illustrator .eps file.  I am placing a 300 dpi jpeg into a new canvas, I rasterize it to work with it and fine, it exports as a 300 dpi jpeg file.  However, when I try to save it as .eps, the dialogue box says that it's 72 dpi.  How do I go about fixing this?

      If you launch your Print dialog, you can set your document resolution there.  Document resolution ( DPi ) is different than raster resolution ( PPi ).  If your raster resolution is 300ppi, then document res should be 2540 dpi.  If your document res is 300dpi, then your raster res can be 72 ppi. Like that.

      Thanks to everyone for your responses.  Just sharing what ended up working for me:

      "you can alter the settings on your current document by visiting the "Effect" menu. It's very near to the top and is called "Document Raster Effects Settings…" - in fact, when you call up this dialogue box you can set the document's resolution higher than 300ppi using the "Other" radio button - something that you can't do when creating a document as detailed above."

      No. You are not changing the document’s resolution. Illustrator files are vectors and do not have a global resolution. You are setting the resolution of raster effects applied within that Illustrator file. Raster effects are not labeled, so it’s not always easy to tell what is or is not a raster effect. Anything that is not a raster, like text or other drawn elements within Illustrator will remain as vectors, with no resolution value at all. Any raster art imported, placed, or pasted in will maintain the resolution it had initially. “Document Raster Effects Setting” will not change anything except applicable effects you apply through the Effects menu. If you only apply vector effects (like Transform, 3D > anything, or Round Corners) then changing Document Raster Effects Setting will do nothing to your file.

        Hello,

        When you initially open Illustrator, the "new document" box should open up (or click File>New) and in the advanced settings ath the bottom, you can select the raster effects to be "High (300 ppi) and it will use those settings. Then, when you go to save your project in an .eps file, it should keep all the settings you initially used to open it with.

        I hope this helps.

        Bev

        That only applies to raster effects. Imported images or other rasterized art will be saved, rendered, and printed at its native resolution.

        Cool,

        Still learning the software too. :-)

        What dialogue box?


        Some basic information: Image resolution is measured in pixels per inch, or PPI, not DPI. Use PPI or sound like a rube.


        Illustrator is a vector graphic application, so anything you create in Illustrator that is not rasterized has no resolution or, if you prefer, has infinite resolution. If something is rasterized in Illustrator using raster effects (Drop Shadow, Outer Glow, etc.) then it will be rasterized at the Document Raster Effects resolution (Effects > Document Raster Effects Setting). If something is rasterized in Illustrator using Object > Rasterize… or Effects > Rasterize it will be rasterized at the setting specified when the command is used. If something is imported that was already rasterized it will be imported at the image’s native resolution.


        So, if you use File > Place to import a 300 ppi JPEG, then the raster data is imported at 300 pixels per inch. If you don’t scale the image and save as EPS you will embed the JPEG image at 300 ppi.


        I don’t know what dialogue box is telling you, or asking you, the resolution of the EPS file. Post a screen shot.
