Side by side or single pages?

Hi

So far the printer has told you what will not work.

Have you asked the printer how they want you handle this so it prints properly on their presses?

Arghh it's so hard for me to make people understand what I mean in another language

So, write in your own language. There are German, Italian, French speaking people, maybe Spanish.

If you really think you need a manually created inside bleed:

Thanks everyone for the answers and sorry for the bad English. I try to better explain what my problem is.
I set up my Indesign document with facing pages and 5 mm of trim on the sides of the pages.
Now, if I have to set a photo on a page that goes to the whole page, that is, that is cut at the extreme edge of the page (as in the figure below), I have to lengthen the image by 5 mm which will then be cut by the printer.
However, when I have to show the client the magazine's drafts with the facing pages, they will also see those 5 mm of photos end up on the side page. I can't edit all the photos by hand :-(.
So, the problem is not to modify the document from facing pages to single pages (when I have to send it to the printer), but to make sure that with facing pages I do not have to manually modify all the images that overlap (by 5 mm) on the opposite page.

There's a lot of good advice so far. Here is my two cents...

When choosing single page or facing page, I ask two questions:

• Am I printing on both sides of the page? (This includes having the job printed), and
• Do I have a distict verso and recto (left and right) page design? (This could be a simple as having page numbers on the outside edge or having a wider inside margin for bindery.)

If you can answer "yes" to BOTH, use facing pages. 

Export should not be a problem, even with cross-gutter graphics(spine gutter, not column gutter) as long as you include the inside bleed. Each page will include the bleed amount for each graphic. 

• If you are using perfect binding, this will be the grind-off area.
• If you are using saddle-stitch, this will be removed during imposition.

I believe I understand your problem. I'm going to go on the assumption that you're finding when you export single page PDFs for your printer that your crossover images are appearing on one page and not the other.

Check with your printer to see if they have a more convenient solution for you, but the default fix for handling problems with preparing a crossover image across two-page spreads is to place two of them.

• When you're working with your reader's spreads in your InDesign document(s), arrange the crossover image(s) where you want them in the spread.
• Select the crossover image with your Arrow/Selection tool. Then select the Edit>Copy menu command to save a copy to the clipboard and then the Edit>Paste in Place menu command to place a second copy of an image immediately above the first one. The keyboard shortcuts are Cmd/Ctrl+C to copy and Cmd/Ctrl+Option/Alt+Shift+V, depending on whether you're on the Mac or Wintel PC platform, respectively, to paste the copy immediately above the first. If you're doing a lot of this, you'll quickly memorize the keyboard shortcuts to speed the process. 
• With your Arrow/Selection tool, select the top image and go to the anchor point in the center of right side of your image frame. Drag it to the left so the right edge of the image is well inside the right margin of the left page of your spread. Don't worry about lining it up perfectly; that's the last step of the process. The important part is to make sure that the two image are inside the margins, so to speak, on each page.
• 
• Now click on the lower image on the right-hand side of the spread. Go to the anchor point in the center of the left side of that image frame, and drag it to the right so the left edge of the image is well inside the left margin of the right page of your spread. If you've done this right, you should see two separate images, one on each page, with white space between them showing the black line where the two pages meet in the reader's spread.
• Choose to the File>Document Setup... menu command. The keyboard shortcut for that is Cmd/Ctrl+Option/Alt+P for the Mac and Wintel platforms, respectively. This opens the Document Setup dialog box. Uncheck the Facing Pages check box, then click the OK button.
• Review your document to ensure that you have a copy of the soon-to-again be crossover image on each separate page of what will again be the reader's spread layout. Adjust the images to meet the respective page margin, or if your printer requires it, to account for a crossover bleed off the gutter.
• Save the file to protect your handiwork.
• Now use your keyboard shortcut to return to the Document Setup dialog and re-check the Facing Pages check box and click the OK button to get back your document layout with reader's spreads.
• Lather-Rinse-Repeat as necessary to provide this service for all your crossover images in your magazine document(s). It's a tedious process, but with practice you'll get it down to less than a minute with keyboard shortcuts.

This is the easiest way I've found to ensure, with no ifs, ands or buts that I've got perfect placement for crossover images when my printer turns the output PDF from single-page layout to printer's spreads to print my job. This takes work, but if you do it right it's absolutely bulletproof.

Hope this helps,

"I was then told that the pdf had to be exported on a single page"

Yes, certainly. A magazine printer does not care about your reader's spreads. You MUST NOT send them reader's spreads.

"which then caused me problems for the images that covered two facing pages."

This should cause no problems. Most of the printed magazines in the world might be produced this way. 

You COULD produce a customer PDF with reader's spreads while makine a separate PDF with single pages for the printer. 

You will design the magazine as a facing pages document, and when you supply the files to your printer, you will generate single page PDFs. The printer has imposition software where they arrange the pages as they need to for a signature, with things like creep and bottling (I won't explain what these are because it's not your worry) to account for the folding of the paper. In very rare circumstances they may come back and ask for a particular page for a specific bleed situation, but this is rare.

If you want, you can create proof PDFs for your client in spreads (as some has mentioned); it helps them picture the flow across a spread, but if they want to print it out, they will probably just have a typical office printer so leaving as single pages is still better for them to handle.

It's a little unclear what you are asking for here but if the goal is to break your spreads down to single pages for the pdf then simply choose "Pages" in the General section of the Export Adobe PDf dialog window which appears when you export a pdf using File>Export>Adobe PDF (Print).

If your goal is to make the InDesign file into single pages then go through File>Document Setup and uncheck Facing Pages. If "Allow Document Pages to Shuffle" is checked in the Pages Panel pull-down menu then the spreads will all automatically change to single pages. If that option is unchecked then the spreads will remain in their original configuration (although it now will have the apperance in the Pages Panel of a single page document) but you will now be able to manually separate them into single pages.
