The output of the Audit Space Usage is exceptionally helpful! What dramatically stands out are the 22 megabytes of “shading information” representing nearly 50% of the file size. This may be indicative of a tremendous amount of use of smooth-shaded gradients in your original source file (or...

Generally speaking, although vector graphics can slow down Acrobat (and any other PDF viewer) page rendering, in practice this is generally not the issue unless one is placing exceptionally-detailed and complex content from CAD software such as AutoCAD or even some mapping software. One thing...

@kdw75, From my extensive experience with Acrobat, especially under Windows, I doubt that the slowness you are experiencing has anything to do with your hardware configuration. It is certainly well-enough endowed. Nor do I believe that the problem has anything to do with any Adobe “start-up”...

Absolutely not true! Only PDF files created from Illustrator files for which the Preserve Illustrator Editing Capabilities option is enabled can be readily edited: Of course, this assumes that any linked content in the original Illustrator file and any fonts used by same are on the system on...

The fact that content pre-converted to CMYK looks “flat and lifeless” is indicative that the EFI RIP is not strictly conforming to ICC color management. It apparently is trying to “improve” the color conversion per EFI's own ideas of what is correct. IIRC, there are options on EFI RIPs to...

Seems like a RIP-specific problem.

Nothing looks wrong to me examining the final PDF file and printing same. However, on a hunch, I made a patch to your final PDF file, removing the transparency group. It shouldn't make a difference, but try downloading the file at ZIP of Modified Test File and let me know whether this eliminates...

Without the actual “final” PDF file along with the original images and InDesign or Illustrator file(s), it is virtually impossible to know what is going on. That having been said, the moment you get transparency groups into the equation, all bets are off since it is possible that color space...

That product may be able to interpret large portions of the ISO PDF specification, especially the portion that is relevant to graphic arts, but its file format is definitely not pure PDF nor is the software capable of handling many facets of features available in PDF.

Didn't say that; didn't imply that!

Note that I am no longer an Adobe employee, but since PDF has features that aren't available in Illustrator and Illustrator has features that aren't part of the PDF specification, I don't see that ever happening. Note that FWIW, the real native file format for Illustrator is private data stored...

HOWEVER, Adobe Illustrator is not, repeat is not, repeat yet again is not a PDF file editor. Contrary to some popular belief regrettably enforced by some Adobe marketing wonks back in the late 1990's, PDF is not the native file format of Adobe Illustrator.

However, you must recognize that “grayscale” and CMYK=(0,0,0,k) are functionally equivalent. Thus, a page may have all objects defined as CMYK yet actually not be “color” but rather all “grayscale.” Similarly, you must recognize that in many cases RGB=(r=g=b) is used as the equivalent of...

I think I heard / read my name used in vain here … ;) There are several issues here. The first issue is that your document initially shows no fonts when you invoke Document Properties => Fonts. The reason for this is very simple. Whoever/whatever generated the PDF converted all the original...

Support for editing live content in InDesign, Illustrator, and Photoshop using actual Type 1 fonts (not OpenType CFF fonts which are effectively Type 1 fonts in an OpenType wrapper) was discontinued with the latest version of the Creative Cloud applications that was released this past November...

That still doesn't address the legal issues I pointed out in my previous response. I'll add one more issue, file size. Assuming one has the editable or installable fsType flag set in the font, embedding full fonts can yield ridiculously large PDF files. Font families such as Arial, Calibri, and...

That “VERY expensive piece of software” or perhaps Switch or PitStop are apparently the problem and they should be fixed. See my response to @chriscozi in terms of legal and practical issues associated with processing of PDF files using any embedded fonts. ;) - Dov

What PitStop is doing is possibly not legal (in terms of the font's original license) and very possibly yields problematic results when doing such edits. In the first case, unless the font is licensed for “editability,” once the font is embedded in a PDF file (or for that matter in an EPS...

Unless you know the exact requirements of the RIP/DFE in terms of resolution, color space, and halftoning, manually rasterizing this artwork may significantly degrade quality. Furthermore, that rasterization process may take just as long as (or longer than) the RIP/DFE processing time.

Exactly what do you mean by “making our work much slow?” Are you referring the time required to process the job on the RIP or DFE? As previously noted by @VanCleef , overly-complex vector artwork could be the root cause of this. The problem is that anything you do to “fix” such performance...
