Topic awaiting preservation: Photoshop & EPS (Page 1 of 1)

Heyas' ive done a little bit of print work, and am vaguely aware of eps stuff. I know the concept of Vector graphics butt..

with photoshop you can save a file as eps BUT as im aware this is of no real use except for text that hasnt been rasterized.. things like graphics, particularly photo's etc that you have included recieve no benefit from the eps format. - i guess with photo's there is no option but to save them in hi-res to begin with...

edit**:
/me answers my own question by researching it on google as im sure Thunder would have pointed out anyhow :P
im still a little confused with some things but i guess i just need to read some more heh

Beat me to it! But in case anyone else was wondering, I'll answer this one cheerfully: you can have raster EPS or vector EPS -- they're two different animals, despite the identical file extension. The "benefit" of saving a raster (PSD, TIFF, etc) file as an EPS is that it becomes readable by any printing software or hardware that supports the PostScript format. This isn't the case for many other raster formats. In general, EPS and TIFF are the preferred formats for raster print graphics.

I guess the term "raster" isn't technologically correct for print images, though... call them "continuous-tone," instead.

Honestly at work when we use EPS it's only because we are having trouble with a portion of document or graphic printing out. Sometimes when we send a document off to a commercial printer they require EPS format and will convert it over before attempting to print it. I guess they can get a higher pixel rate and the print out is clearer. (not that I know).


This might help answer the question.

What is the EPS (Encapsulated PostScript) File Format?
November 9, 2000



General

The EPS (Encapsulated PostScript) File Format is one of the most popular developed by Adobe®. EPS is a sub-language of PostScript® and can therefore be used on both the Macintosh® and Windows® platforms.

The EPS file format is designed to support very complicated graphic files consisting of vector elements and raster (bitmap) elements. They can either be combined or separated.

NOTE: BMP or TIFF formats can only support raster elements.

Fonts in EPS Files

PostScript fonts are vector descriptions of different types of fonts, such as Times Roman or Helvetica. When inputting text in the EPS file, the actual ASCII code and font name that represent the vector description of the PostScript font is written.

The PostScript form (vector descriptions) of the most popular fonts is located in this case under the RIP directory with 35 different fonts under:

c:\accusrv\font

or

c:\colorpro\font

Once the EPS file is sent to the printer, the PostScript fonts library supplies the full vector descriptions that are required to create the desired text.

The main advantage of an EPS file over a BMP or TIFF is the reduced file size. In addition, no matter how much the EPS file is enlarged or reduced, just like other vector components, the font will always be smoother and cleaner than corresponding BMP or TIFF files. Fonts in these other formats are pixelized and the edges become jagged.
