: Pros and cons to .AI vs. .EPS file formats in 2017? I've heard "EPS is a dying format" so many times my brain completes the sentence every time I hear "EPS"...yet whenever I research the

EPS is a programming language, not a format as such! The definition, as a programming language, leads both the best feature of EPS as well as the worst feature. EPS is not dead, just being strangled by mom. It's purpose has reverted to more traditional uses.

EPS is great, if you are publishing stuff from several sources but have no way of integrating or no interest in doing so. What you do is you just inject the EPS file as is into the printer stream and the downsream application (RIP, Distiller, GhostScript...) or printer handles the stuff for your output. This has several advantages:


Decissions can be done closer to metal. You could hand craft your EPS to know wheter its being printed in black and whote or color etc.
You do not need expensive applications to do this. A text editor is enough.
...


But nobody is doing this! Why? Well you have been sold a adobe centric way of working. EPS is threath to Adobe! Which is the main reason it has not been updated. Need CMYK images in word? Use EPS, because no matter what word does if it can send the eps downstream intact who cares how bad Word is at doing things the EPS overrides word at the printer.

Ok so EPS is a bad general purpose format. Because it is a programming language it has several weaknesses. One, its not so clear how to read a custom EPS entity. Sometimes it works fine, other times not so fine as all the cool features done in the EPS need to be ripped out.

EPS was killed by Adobe, it is sortof dead, PDF has superceeded it and EPS has not been updated since forever. Admittedly, though, adobe has lost some of the edge when it comes to PDF as of late. So it would not surprise me if a Adobe rolled out a new pipeline.

EPS is a bad format if you rely on intellectual property as your business. As it makes your custom stuff being easily read by others.

Well, an interesting question would be... who killed EPS and the answer is PDF (Was not not AI)

Not asking for a PDF for fear it is a raster image inside has little sense to me. (But I really understand what you mean)

If a person has the vector file it is most likely they will send it to you if they don't... probably they will not.

A lot of EPS I saw around some time ago (I do not use it for quite some time now) is a bad auto traced version of an image or a total useless file, for example, the gradients could be separated into a lot of solid color bars... or, you guessed it, a simple photo inside.

A modern version of a PDF will keep the node information, gradients, transparencies, etc.

But at the end you probably need to be clear with your client and to give them options. If they have a EPS, PDF, AI, CDR, SVG, let them send it to you.

If they send a raster image charge them a small fee to vectorize them... and they will put more effort to find the vector file.

Realize that "EPS is dead" comment customarily comes from people in the industry 5 - 10 years or more. There was a time when EPS was king and everything as an EPS was better - even straight raster images, due to color profile embedding and clipping paths. That hasn't been true since the 90s or 2000s however.

Note that EPS is just a "wrapper" and can absolutely contain raster images. Requesting and EPS does not mean there is no raster data in the file.

EPS may not be quite dead..... But it is kind of a "zombie" format with very specific uses today. Realize today, the EPS format offers nothing really unique in itself, except how the "wrapper" is written (i.e. compatibility). There's nothing one can do inside an EPS that can't be done in a PDF for example. So the EPS format generally comes down to a preference more than anything.

As you've discovered... transferability, inter-application exchanges, and legacy software are really the only reasons vector EPS is still a viable choice at times. And straight raster EPS files are pointless in today's world and truly are dead as a format.


Some applications (Inkscape, Sketch, etc) can't write .ai files. Its a proprietary format. But they can write EPS files. So you aren't restricted to only using Adobe product by using EPS files.
The converse is also true.. not every application out there can utilize PDF or .ai files. Embroidery machines and other industry-specific software has never been concerned with anything beyond EPS. And I don't know about more recent versions of QuarkXPress, but last I looked it wanted EPS files as well, not allowing import of .ai files.
EPS files kill alpha transparency for the most part. If there's a concern that subtle transparency is used in a design, requesting an EPS file generally will take care of that. There's no "blending modes" in an EPS and alpha transparency is flattened to 1 bit - either "on" or "off". This in itself can show the inexperienced a great deal about how files need to appear for reproduction.


With all this posted, for offices working among themselves, sharing files in their own building, among their own workers, and either sending PDFX-1a files to press or creating screen images, EPS really is a dead format. It is only when unknown workers will be touching files that EPS even enters the mind. There's zero reason to send an EPS file to an Illustrator user if you know the version to save to. There's no reason to send an EPS when a PDF is more staple, contains transparency, type hinting, live text, etc. unless someone states they need or require an EPS.

The only reason to use an EPS today is if a file is leaving your office and an EPS has been requested, or if you simply don't know what someone will send you so requesting and EPS circumvents some common issues with other formats.
