Do you do any adjustments, clipping masks, effects etc. on the linked file? If so, AI sometimes converts it to an embedded file to retain appearance, which is intended behavior, if it cannot do this on the "life" linked file. Especially working with spot colors can cause this, even when you add just one such element on top of the image and define it as overprint or knockout...
Thank you for answering.It happens with CMYK files. I haven't used a clipping mask. I routinely use the overprint feature on elements that are on a layer above the .tif, with no resulting problems. I always lock the .tif layer to prevent bad things from happening.But if you are saying that some kind of file conversion can happen automatically to "retain appearance", and that no warning or verification occurs, that is interesting. Do you know of a way to reverse this effect?
One of the reasons why the tiff file may become embedded and more than likely the reason is there is a option in the eps saved dialog that is a bit misleading. The option is to include linked files which would seem to be saying yes you want the linked files to appear in the document but insteads means to embed them.
I will make a feature request on the feature and bug report page to have this wording change to embed linked images. So it is clear what the option actually does.
I just filled out the form and made a feature request as such
In the "Save As" eps and ai options dialog there is an option that is titled "Include Linked Images" this is misleading to most users even experienced uses since this option embeds any linked image in the document. It would be better to cut to the chase so to speak and simple title it to "Embed Linked Images" The problem with the way it is currently worded is that it seems to mean that you want your link images to remain linked in the file. Quite the opposite of its intent and actual function.
You can find the form if you wish to change the wording here:
Thank you, the wording change is good. However, I don't think that's what is going wrong on my files. The option to "Preserve links" is understandable.
Is there any way to change an embedded file to a link, without re-placing and then re-saving the file?
I will keep looking at options and see if I've inadvertantly clicked something on the .eps menu. I thought I ruled that out, but if you aren't getting a lot of complaints, it must be something I'm doing.
The option to "Preserve links" is understandable.
I don't know of this option where do you see it? If you are referring to include links that actually means to embed the link files and not to perserve tham as links.
Unless you are referring to an option I am not ware of where is this located, in what dialog?
After saving an .eps file with a linked file, a menu will pop up to prompt you one last time, before closing the file. There are 3 choices, plus an explanation. The choices are "Preserve links" "Embed file" or "Cancel". You have to pick one of these before the file will close.
I haven't used eps format for a long time and do not recall that dialogbutyes that would indicate that you have not checked the "Include Linked Images" option.
Have you tried trashing your AI preferences?
Yes, if that dialog box comes up, the file contains a linked file and it is OK. If dialog box does not appear, the file has defaulted somehow to embed the image.
My clients want .eps files, so I'm stuck with that.
But it's possible that I saved the file without noticing that somehow it defaulted to include the linked files. Then forever after, all copies of that file default that way. (I make a lot of copies to preserve the printer's ID tags).
It has to be something I'm doing without realizing it, and this is helpful. Thank you.
