Scripting Acrobat

[kaiserwilhelm]

I have a very talented Indesign scripter on staff. The scripts he has written for our department save us hours every day. We are getting in more and more pdfs (supposedly run ready) from clients. In the commercial web press world, I must have .187 plate gap.
Is there a software, or do you think it is possible to have a script / hotfolder where a PDF is dropped and a KEYLINE of .187 is put on the document from all four edges? IE, 8.5 x 11 would have a KEYLINE color (set to overprint) added to the PDF that is .187 from the top, left, right, and bottom?

I don't think that can be done by scripting Acrobat alone. What I would do is import the PDF in InDesign, add your stroke frame all around and re-export as PDF. I've came with the following. Save the code as AppleScript application and drop any PDF on it's icon. It will open the PDF (or multiple PDFs that will process one at a time) to gather page number, PDF width and height, then place the PDF in InDesign, add the overprinting stroke all around and export a new "refried" PDF to a desktop folder named "Refried PDFs". I wasn't sure if you wanted the stroke weight to be added to the document size. Right now, the script will take a 8.5 x 11 PDF and center it into a 8.874 x 11.374. Tested it here and it works. You can also edit the code to attach it to a mac hot folder by using the "Configure Folder Actions" on your mac so as soon as a PDF will be dropped in, it will trigger the script.

I appreciate this script. I will give it to my INDD scripter to try. My only concern is "re-fring" the PDF. We work in an APPE format. I wonder what will become of my unflattened PDF??
Does anyone from Adobe know? I am SURE they will just gasp at the thought of going into INDD.
However, I might just use this as a way of making sure I have plate gap and then (if I do have plate gap), using the original PDF?

Although the export folder is titled "refried", I personally do not consider *exporting* a PDF to be "refrying". I think of refrying as going to *PostScript + redistilling*. Exporting a PDF of a placed PDF from InDesign is not in the same class, even more so if one is using a PDF version format that does not flatten.

As mentioned toward the end of the script code, one can use any PDF export preset name, so it is possible to make a custom PDF preset setting to for use with this script (no jpeg, no resampling, no flattening etc).

Colorblind, I tried the script with AcroPro9 & InDesign 5.

The script reports an error of "data is out of range". The PDF is placed on the ID page, however no stroke colour or stroke is applied and no export takes place (the output folder is empty).

P.S. Is there code to set the stroke attributes to overprint, rather than just the swatch name?

I like what you have done so far!

As Stephen said, placing PDFs into InDesign and re-exporting is _NOT_ refrying.

@ Leonard

Thanks for the clarification about "refrying".

@ Stephen

As I said, I tested the script here and it works but, as they say, programming is 10% coding and 90% debugging. Will try to have a look. As for you stroke attribute question, in the lines:

set RectangleImage to (make new rectangle with properties {geometric bounds:{0, 0, new_page_height, new_page_width}})
set stroke weight of RectangleImage to (keyline_weight * 72)
set stroke alignment of RectangleImage to inside alignment
set overprint stroke of RectangleImage to true

The variable RectangleImage is a reference to the rectangle (or frame) that will have the stroke applied to so the line "set overprint stroke of RectangleImage to true" will overprint the stroke.

I quickly wrote another script that should set all strokes of rectangles, text frames and polygons in any open InDesign document to overprint, (your mac should beep 3 times when it's done) but as I mentioned earlier, writing the code is only 10% of the work :-) so forgive me if it doesn't work perfectly on your machine.
That being said, thumbs up to Adobe for implementing so well AppleScript into InDesign and Photoshop.

set volume 5
tell application "Adobe InDesign CS5"

set doc_count to (count every document)

end tell
--this is to ungroup all groups or else strokes that are in a group wont overprint

set my_groups to get every group

repeat with this_group in my_groups

ungroup this_group
end repeat
end if
end repeat
--end of code to ungroup
set my_rectangles to (every rectangle whose stroke weight is not 0.0)

Hey, I'm just happy to be a senior member now! Guess it comes when you have the only CiPress 500 digital web press in the nation sitting five feed from your Mac!

[kaiserwilhelm]

Leonard, I am shocked! Pleasantly shocked! I thought for SURE you would say that that is not a proper way to make a pdf.
Are you giving me the Adobe blessing to place a pdf in (1.7) and export back out (1.7)?? I might just owe you a beer and or Coke if so.

Thank you Colorblind for pointing out the part of code about overprinting (obvious now that you point it out).

And thanks for the script, it is appreciated and I do understand the issues with scripting and coding - so I am grateful for what you have done for the community in this script! As the script errors out before making the spot colour, I am guessing that the problem is somewhere there in the code...

You have done all the heavy lifting, it is not hard to simply add a new layer above the default and to then create the colour and apply the stroked overprinted frame to this new layer on the master page - then export.


Best,

Stephen Marsh
