Illustrator :: File Size And Performance Using PDFs From CAD
Aug 1, 2013
Using Illustrator CS5.5, I'm trying to open and use floor plan PDFs originally created from AutoCAD, Revit, etc. The files contain detailed vector artwork, but the file sizes and RAM/CPU usage I'm seeing don't seem to correspond to the information in the file. I open a 2MB floor plan PDF and when I save as Illustrator, it becomes 20MB. It takes 2GB of RAM to open that file.
I've checked for masks and transparencies, but can't figure out what's making these so difficult to work with. Are there attributes I'm not checking that could be slowing things down?

I run a department that cleans PDF architectural drawings in Illustrator and Photoshop for use in online documentation software. I am currently working on creating spreadsheets laying out "if plan is 1/8" = 1', scale at 'X' %", etc, as up until now it is simply done by eye, but we try to scale up or down all plans to roughly the same size. While trying to determine a scaling ratio to create these charts, I realized that when I imported the same PDF into AI, it resizes the image, where as when I import it into photoshop, it imports it at full size. For example, I took the same PDF and dropped it into AI, and it was 2108 x 2881, and when dropping into PS it was 8788 x 12007
How can I import a PDF into AI and PS and have them be the same dimensions?I saved a GIF file 5,000 pixels wide, and it imported 5,000 pixels wide into both programs, so it appears I am only having this issue when working with PDF files.

I am trying to send a file to a newspaper for print. Only thing is Illustrator makes the files massive.
A normal newspaper ad ends up to be 58MB when converted to PDF. When i make something in Indesign it only exports to about 8MB for PDF.

Our supplier sent us some wierd size pdfs that are not full size or half size. I am trying to resize them to full size pdfs (Arch D) but am unable to figure this out in Acrobat.
My work-around is to insert them in AutoCAD and scale them based on known dimensions, then print to pdf. Unfortunately the resulting file is collosal and the quality degraded.

am having an Issue with CS6 when saving files. When saving a file using the 'Save' option (not 'Save As') the file is not staying at the size of the artboard as it should, it is however being aurtomatically cropped down to the actual artwork size. This is causing issues with the Process we work with as we need the file to stay at the artboard size.If I click 'Save As' and change the Adobe PDF Preset to 'Press Quality' then this works, however this means that every file we save(which is quite alot in a day) means we have to go through the 'Save As' option and manually change each save.why this has suddenly started to happen with our Illustrators and do you know how to fix this so that it stays at the Artboard size when 'Save' is used?

So, I'm trying to create a repeat pattern of a Balloon illustration I've done in Adobe Illustrator. I've got the singular file (balloon.ai), which weighs in at around 700MB.
Now I'm trying to create the repeat of this pattern on a separate Artboard which will repeat these balloons, 30 balloons per repeat square to be precise.
What would be the best way to import these separate balloons into the repeat square once (as they're the same file) without affecting the weight of the file and performance of Illustrator?
So, in essence, is there a way to import that balloon.ai file and only have it use up 700MB on the page rather than 30x700MB by the time I've placed 30 balloons?
I can't rasterize the files as the printer needs the raw file.

One of my co-workers has drawn a shoe (I work in the clothing-business) and is experience huge performance issues on that specific file. We've tried in both CS5.5 and CS6 with no difference.
When I try to rasterize the drawing, Illustrator stops responding. I've tried Simplifying and Cleaning up the paths, but with no lucks. It's not a particularely advanced file, but there seems to be a LOT of paths.
According to the "Document info"-window, there's 110,823 paths (67 open). On another drawing of a shoe (which has some similarities in looks etc.) there's only 86 paths (10 open).
How can I reduce the number of paths? And shouldn't I be able to see all 110,823 paths in the drawing?

I designed artwork for a large banner (84" x 32") so my AI artboard is that large. As you can imagine, with all the text and graphics I used, this file size is 22.8 MB. I need to email this art to the printer, but the file size is too large to email. How do i go about reducing the file size in AI so it still maintains large format print resolution? Will saving to a PDF lose the print quality?

I wrote a little Script converting an Array of Strings to outlines for SVG export. I however find the results of createOutline() extremely unsatisfactory, especially when compared to the results of doing the job "manually" (Right click > create outlines).
Right click, "Create Outlines"
createOutline() from Script
From first sight this seems like an issue with conversion accuracy set too low, however I wasn't able to locate a parameter to change the same.
How to achieve the look of the top image from within a script.

how to improve Illustrator (CS6) performance on a photo-heavy document.
The document is best described as a "catalog" style piece. It contains 2 artboards (front and back) with approximately 30 item images on each side.
When I work on this document, after every click, tool selection, or almost any action, Illustrator "sticks" and goes to "Not Responding" temporarily, then becomes stable again for me to perform a function - then it will stick again (and repeat).
CS6/Windows 7

I produce documents in AI, and save them to pdf. Then, in order to reduce the file size, I load then into PS, flatten image, then resave as pdf. All are in CMYK.
There appears to be a big difference in the output pdfs from AI and PS. In the PS ones, blacks are very grey, and drop shadow effects become exaggerated. I've attached some screen shots. I hope you can see the differences. The AI ones are on the left. It is quite hard to see the differences here, but across a whole document it is very obvious.
What can I do to stop the PS pdfs turning out this way?

I email a lot of pdf's out of Illustrator and have a saved setting. I am basically using the smallest file size setting but with bleed and trim marks. Files normally come out about a MB or smaller. We recently upgraded to CS 5.5 just after All of a sudden for about the last 2 weeks when I save a pdf the files are 10 MB or bigger. I have tried just about everthing to reduce the file size and nothing is working. Why this would have happened and what I can do to fix it. I had to export the files as jpgs in order to make them small enough to email.

The first time it happened, I uninstalled AI and did a fresh install which fixed it for a short time. When I save a PDF out of AI, it does not save to the artboard constraints. This is a screen shot of my AI document which has 2 pages.
When I save as PDF, this is what the file looks like:
(Pg 1)
(Pg 2)
After the original file has been saved (incorrectly) I can open it and save it again and it will be fine.

Prior to printing my work, I save PDF versions of my files. More often than I'd like, when I print the PDF file from my computer, some of the graphics do not print correctly. For example, a portion of a curved graphic (like a swirl) might be cut off leaving a blunt straight edge. Have issues with PDF files? Is there anything I can do to control this quality issue?

I work for a large format printing company. We receive thousands of files every year from many different designers. We started to notice that gradients would drop out of some PDFs when opening them in Illustrator but they would preview fine when opened in Acrobat. I searched high and low for an explanation for this glitch. The only response I received is "Stop opening exported PDFs in Illustrator." The downfall with these workarounds: all spot colors located in the gradients will convert to CMYK mixes. I'm still researching to see if there is a way to keep spot colors intact in these areas.
A little back story: InDesign is converting the gradients into something called NChannel. It enables more accurate handling of color blending by including additional dot gain and color mixing info. Both InDesign and Acrobat have the ability to display these elements whereas Illustrator, from what I’m finding, does not. Which is why we’re seeing gradient elements drop out when opened in Illustrator.
Workaround for CMYK Gradients
Open PDF exported from INDD in Acrobat
Go to Tools > Print Production > Convert Colors
Object Type: Smooth Shade (this tells Acrobat to hone in on Gradients only)
Color Type: DeviceCMYK
Check Embed next to Conversion Profile (should be SWOP)
Expand Document Colors on the right and Select DeviceCMYK in Color Spaces then click ok
Save the PDF
[code]....

I have a business card file created in AI CS6. The file has two identically-sized art boards with crop marks. All the fonts are outlined, there are no linked graphics. I've opened the file in AI CC, made some minor changes, and tried to save as a PDF. When I open the PDF in either Acrobat Reader or Pro XI, there is no content, only the crop marks.
Interestingly, the desktop icon preview, and the open dialog box preview both show the content, and when I open the PDF in AI CC, the content is there. But when I open the file in either version of Acrobat, the content is gone. Just the crop marks show.

I am using trial of Adobe Illustrator CS5. When ever I export file (RGB) to PNG or JPG format, there is size difference of 1px in width or hight or both. But when I save that file with Save for Web & Devices option, then there is no such issue.
I have tested with so many files.I didn't faced such problem with Illustrator 4.

I was just provided a pdf for a large. The customer however forgot to build in a bleed. I can see from the imbeded info the file was made in Illustrator cs5. Knowing this I opened the pdf Ill cs5. When i attempt to do this I get an error that there is a linked image missing. So I figured I would place the whole pdf in a new illustrator file. When I fo this I can see all the illustrator layers from the original file. Including the image that supposedly wasn't linked.
Once I have the place pdf in illustrator I can edit the original illustrator elements just fine. The only problem is that now when I try to save this file as a pdf again it's file size grows about ten times, going from just short of 5 mbs to 45 or more mbs. This larger size keeps me from emailing it and unfortunitly the banner printer I was sending it off too doesn't use dropbox.
How I can add a bleed to this pdf without making the file unresonibly large? I have already tried turning off the all optional inclusions on the pdf such as allow Illustrator editablity.

I have an ai file. It is exported from PRo-E, so there are lot of nodes in that ai file which makes the file size larger. Is there any way to simplify the ai file without disturbing the profile of the entities in ai file. I tried Simplify options. It worked a little bit. But i want any other option to simplify the ai file in order to reduce the file size in a larger extent.

Many of our AI-files have a tendency to 'bloat' to sizes above 60 or 100 MB, even though they relatively simple, all things considered.
The obvious answer would be to save with PDF-compability, but since we need to link the AI-files in InDesign-documents, that's not an option. We have cleaned the brushes, the symbols etc. and all pictures are linked, not embedded.
Are there any other ways to reduce the file-size?

Recently I upgraded fo Illustrator CS6 and found something that is going to screw up my working with clients. The problem is that the .ai and .eps files are having really huge size (67MB on an average). I have used about 6 images (jpeg at 1024x768, less than 1MB each) made them as pattern in the swatches panel and applied on various shapes. The .ai file size is 109MB :O :O :O . Another ridiculous thing is that an art that contains only 3 lines of text plus some circles and squares (3 circles, 2 squares) filled with solid color is around 68MB.
how to reduce the file size without compromising on the pattern quality.

I have several documents with what I call "reference layers" in them that I turn off when making a PDF. When I view the PDF on a Windows based machine, it is fine in both FireFox and IE. When viewing the PDF on a Mac product (iPad, iPhone, Mac desktop), the layers I have turned off are showing up in the PDF.

what I need to do to my PDF to ensure color are some what close to original when saving a PDF in Illustrator or InDesign. Yes i understand iPad would be using a different coor management to a desktop computer but surely there is a way to get the colors, brightness closer to original?
I notice that when doing standard and high quality saves in PDF format, the saturation and brightness contrast changes quite a bit, but if I save the image as a jpg its a lot closer.
I was just browsing a car site which seems to be exeriencing a very similar situation with one of their PDFs. When viewing in iPad have a look at how bad this looks (its way too dark) but when viewing on a desktop machine its fine.

Is it just a matter of color proofing using a specific model and drawing back on blownout levels before outputting to PDF?

I need to find a way to convert a LOT of ai files, individually, to low res pdf's. Preferably with the presets I want, not some defaults. I'm not interested in an action. I was hoping for a droplet, script, or something similar.
I did find this and it looked promising... [URL] ....
That almost worked. Ultimately, for some reason, it couldn't see the ai files sitting in the specified folder.
