Overprint preview setting in Javascript

Hello-
I'm trying to control Acrobat 7's preferences through a javascript, specifically, the overprint preview checkbox.
In the past I've used
if(app.runtimeHighlight)
app.runtimeHighlight = false;
to control field highlighting.
I hoope there's a similar setting for overprint preview.
thanks for any help!
Ralph

there is not.
With the newer versions of Acrobat, you don't even need to worry about it. So just upgrade...

Getting overprint preview preference in Adobe Acrobat 9

Hello,
yesterday I installed the Adobe Acrobat 9 Trial and I tried my plugin.
Does anyone know how to get the overprint preview setting?
In older version of Adobe Acrobat I'm using following code:
AVAppGetPrefBool(DSAVSettings[prefNumber].m_section, DSAVSettings[prefNumber].m_name, (ASBool)DSAVSettings[prefNumber].m_requiredValue_9);
m_section is "Originals" and m_name is "OverPrintPreview".
In Adobe Acrobat 9 it always returns the default value m_requiredValue_9 which means that the setting can not be found?
Do I have to change the value of m_section or m_name or do I have to use an other method?
Thanks for your help!

I'm having a problem with securing specific fields. Not sure if that can be done. I have a form that I created in LiveCycle Designer and the forms contains fields that create a basic calculation for example (Qty+Price=Total). I want those fields to be field out by our sales people and I want them to save the form with the info. field in and email to customer as a quote basically, but I don't want the customer to be able to change those numbers, but I do want the customer to fill in other portions of the field. Having a problem doing this cause Acrobat is only letting me secure the whole form and not just portions. Is there a way to only secure portions of a form. Please help ASAP.
Thank You

Overprint Preview and Workspace are set to the same, but look different

I'm working for something to be viewed on a screen, so I work in the sRGB IEC61966-2.1 (Edit > Color Setting > Working Spaces - RGB: sRGB IEC61966-2.1 ). I have set the Overprint Preview to the sRGB IEC61966-2.1 as well (View > Proof Setup > Device to simulate : sRGB IEC61966-2.1). But when I tick Overprint Preview the colors look completly different. Why?
Thanks, Andi

Maybe you are right and it doesn't make much sense to use the Overprint Preview in this case. I think what happens is, when you tick Overprint Preview, ID converts from your actual RGB-Color Space to a set CMYK-Color Space and back to the old RGB-Color Space (if set to the same one). On it's way the colors change through it's conversion from RGB to CMYK and back to RGB. That could explain it.
Thanks a million, Andi

Acrobat 9: Overprint Preview

In v7, the option to view a file in OP Preview was on the main menu bar (Advanced, I think). I could toggle it on and off at will. Convenient.
In v9, the only place I find any OP setting is in Preferences>Page Display. Is this correct?
If so, can I assume Use Overprint Preview>Automatic will toggle on OP Preview when a file has overprinting and not when the file has none? Is this the setting most of you use?
With this setting, can I assume the only way to turn off OP Preview when viewing a file with overprinting is to return to preferences settings?
Thanks.

You are correct, Overprint Preview > Automatic automatically detects if there is content in the document that requires overprint preview to display it accurately. Changes to the preference should be immediately visible, without having to quit and relaunch. Are you getting different behavior? If so, what OS are you on?
There is one other way to toggle off overprint preview temporarily when it is enabled by the preferences. WIth the Output Preview dialog open, there is a checkbox to turn on/off Simulate Overprinting. This on/off toggling only works while the Output Preview dialog is open.
Color Warnings view in Output Preview should still highlight the objects that are set to overprint. Additionally, you can use Preflight to determine if there is overprinting content in the file. There currently is no message bar or overprint indicator icon.
Also note that, even with the Never setting selected, overprint preview is automatically enabled when the Output Preview dialog is open.
I hope this cleared up your questions?

Overprint Preview question and another issue...

Hi...
CS4, Win XP.
Overprint Preview question:
The other day i sent a file for printing (poster) in PDF and CS2 formats. For some reason, the printer converted the file to a .tif and then printed. Parts dropped out... Both the PDF and CS2 files looked fine.Description follows:
1/ Background black
2/ Design element over the black (blue lines to form a wave).
3/ Logo in red and white. Plus a line of text in red. And other text in white.
The white of the logo vanished. The red line of text kind of vanished... printed very faintly and only (i think in parts). Printer tried to do a patch job of printing the line separately and pasting... anyway... to cut a long story short, he wanted the final output in .tif. OK...
So, i converted to tif and sure enough... those parts vanished... did a search here and found the solution - view file in Overprint Preview and then in Attributes, turn off the Overprint Fill... so all well...
So, the question is, why does this happen? And, how, do i know in advance that x or y is likely to cause a problem? I have noticed in Bridge that sometimes, parts of a logo or a line of text does not show... but looks fine in AI or Acrobat... now realise the cause, but not the reason.
The other issue...
Same black background(s)... placed Photoshop file/s with a transparent background... Prints fine at the printers (various machines and media) ... But on the laserprinter an HP Color Laser Jet CP1510 series, there's a dark patch around the image (the actual file area).
Again, any ideas?
Cheers...

<snipped>... so if your looking for this forum to play detective and tell you who in your workflow set the elements to overprint, I don't think this can be done. I don't think I have ever seen Illustrator set any elements to overprint all by its self. <snipped>
Hi PrepressPro...
Many thanks for your earlier inputs, but not quite sure where you got the idea that i want someone or anyone to play detective... i've understood the Overprint problem... and moved on. If anything, maybe i was just musing and wondering if any particular action turns on "Overprint Fill"...
Or maybe, i was referring to the second question which has not been resolved yet... Quoting it below for easy reference:

To elaborate, the pix above are product shots which have been cut out and placed on a transparent background... The PS file is then placed in AI CS4 with the object option selected to maintain transparency. The transparent area is printing darker on the printer above. But is fine when sent to commerciqal printers...
Attached is a scan of the problem...

After saving a PDF with a Spot UV layer, all of the highlights and detail under the spot color are flattened in Overprint Preview. What am I missing here?

I'm attempting to print some business cards with a Spot UV coating. I have a layer above the artwork with a spot color (set to green per the printer's request). Underneath is a logo, essentially a red circle with some highlights and depth. My issue is that, after exporting a PDF, all of the highlights and detail on the red circle disappear in Overprint Preview (it's there when I hide the Spot UV layer, but missing when I hide the Spot Color). What can I do to retain that information?
Thanks!

Let me know if you need different screen grabs. Thanks in advance.

Pixelated images and overprint preview

I have a few images already inserted in a document which are all in CMYK at 300 dpi. When I zoomed in on them, they appeared just like they did in photoshop, nice and clear.
Last night, I started having trouble with the images appearing pixelated when I add them in. I couldn't find any differences in my workflow in bringing them in, which is the strange part. They are all 300dpi. When I placed some images last night, they appeared pixelated when I zoomed in. Also if I chose Place and just clicked one time, they would appear huge, more than the size they were intended to be, which makes me worry the document may not be setup right, but I cannot find anywhere to adjust the dpi of the document. I have it set for Print, 6x9 size but I dont see where you would modify the dpi for the print setting.
I made a flattened psd image which shows up in InDesign's info window as 300 dpi/cmyk but when I add it, it tried to make the image huge. So I used a different method and scaled the image into the area I wanted it and it still looked very pixelated when I zoomed in.
I looked around and turned on the setting overprint preview and the image cleared up. I am about to be placing a lot of images in this document to finish the book so I am trying to get a better idea of what is going on first and make changes to my document if needed. My question is - If the image doesn't display well when overprint preview is off, do I need to worry if it looks good when its turned on?
Pic 1, overprint preview on. Pic 2, overprint preview off.

Yes I understand this. I was just worried because strangely, other images I had placed before I did this one were not behaving in the same way. I had scaled them down, which is the only difference I could find. I was just very concerned thats all. I know it may have been a simple question but I am finishing a huge project and just about to drop a lot of work on prepping the photos for my book, so I wanted to double check the process very carefully to make sure I wasn't about to repeat a mistake somewhere 100x...

Overprint preview spot colors

Hey All,
one of my collegues brought something to my attention and we are wondering why Illustrator does it. Here is the situation.
We create two layers. Layer one contains some objects filled with process colors.
The second layer contains an object filled with a spot color and the layer is set to non-printing.
When you open the separations panel and turn on overprint preview it seems that the spot color is converted (temporarily) to process. When you turn of the spot plate the object still show and starts to disappear when you turn of the process plates.
The spot object does however disappear when it's plate is hidden once it's layer is set to printing.
Why does Illustrator do this?
We expect the spot object to disappear when the plate is turned off in any situation.

You are right experiencing the same here, and agree with you that the spot should not show in cmyk when the layer is set to not print.
Turn off show (or the visibility eyeball) for the spot layer if this bothers you.
Looks like a bug, I believe have originally seen many versions ago, and never been resolved cause not many people asked to get this fixed.

PDF showing overprint preview

Is there a way to output a PDF that looks like Aunt Illie's Overprint Preview?

Oh ok, thanks.
Ah yes, I meant to comment on that - I tried it and it seemed to do nothing. Though, I don't understand Flatten Transparency at all. I've read about it, but have never worked with it.
Here's my attempt:
Afterward, it all looked and seemed to be unchanged.
Another screenshot for ya (with no Flatten Trans done) - The pink swooshy shapes are screens of a PMS, set to overprint. Here you can see my setup with one selected, along with my workspace panels mess (yes, that's a little extra Hieronymous B. wallpaper action for the fine art lovers in tha hizzouse):

Overprint Preview question

I am trying to print a film positive for a spot UV job that is supposed to have some text reversed out of it. Output Preview does not show the text. My RIP does not see it either. I can only see the knocked-out text when I turn off overprint preview in Acrobat preferences. I guess my question is what did the artist do wrong when he made the PDF? Also, is there a preflight profile I should use on all the files I receive, to prevent this confusion from happening again?
I am using Acrobat 9.5.1 on Windows 7
RIP is Roland VersaWorks

Do you know what software the artwork was created in?
If I didn't see reversed text, I would first check that the reverse field object was not set to overprint -- which would eliminate reversed-out type. Some other issues can interfere with reversed type -- using an unavailable font for example, or the text not being set to white, and several more exotic settings and techniques. Some DP software has trouble knocking out type if it's not the frontmost object on the page.
BTW, the title says "Overprint Preview question" but I think you're just asking about "output" preview, though it did make me think of the overprint setting issue.
As to preflight profile, you have to make sure everything is set right for your particular output device/print conditions. You might want to run a profile that checks for missing fonts, low-resolution images, non-CMYK inks -- anything that would give problems in film/plate output or on the press.
Also, when I have text problems, I try printing to other devices -- laser printer, inkjet, whatever -- to see if the problem is device-specific.
Hope that helps a little

Overprint preview

I'm using CS2. Is there a way to get overprint preview to be the default mode for InDesign display? I'm getting really tired of having to select it every time I launch InDesign.

I doubt you can script it in CS2 because there are no scripting events. In CS3 or later you can set a script to run any time a document opens.
In CS2 you could assign any key command you want and at least avoid the menu.

Overprint preview - default

CS2 - Is it possible to have "overprint" preview on by default?
Regards
Nina Storm

I'm not sure if this is the answer Nina, but I am trying this option from the Help Menu.
Choose either Edit-> Preference-> Display Performance (Windows) or InDesign-> Preferences-> Display Performance (Mac OS), and make sure Preserve Object-Level Display Settings is selected.
Choose View-> Display Performance, and make sure Allow Object-Level Display Settings is selected.
With the Selection tool or Direct Selection tool, select an imported graphic.
Do one of the following:
Select Object > Display Performance, and choose a display setting.
Right-click (Windows) or Control-click (Mac OS) the image, and choose a display setting from the Display Performance submenu.

How to export 'CMYK/Overprint Preview' document to jpeg/pdf?

Thanks.

Appreciate ur help....
Actually What I want to do is that there is my original document containing some arts or objects like as follows:
Currently doc is set to CMYK/Preview. Now I clicked the menu item Window>Separations Preview where i checked the Overprint preview, this will set my document CMYK/Overprint Preview and I unchecked Cyan, Yellow and Black from separation preview dialog which gave me result like this :
I am trying to export the above overprint preview but every time I got the original one.
I am using AIRasterize suite to get the current state of the document and export it but didnt find any luck. I am also trying to do it on illustrator but I am not able to do i.
So I am just curious can it be doable or not?
Thanks.

How Can I Set a Javascript Value into an Attribute of BSP PAGE

Hi
Can anyone tell me.
How Can I Set a Javascript Value into an Attribute of BSP PAGE

Hi Mithlesh,
javascript runs on client side and you cannot assign the value to a Page attribute directly.
As a workaround,you can use an Inputfield,hidden if required,and set the value using javascript.Then the form will have to be submit to be able to read the value in onInputProcessing and then can be assigned to any variable.
In Layout
<head>
<script language="javascript">
function pass()
   txt1 = document.getElementById("ip_mrf");
   txt.value = "hello" ;
</script>
</head>
<htmlb:inputField id="ip_mrf"
                           value="<%=mrf_number%>"
                           visible="FALSE"/>
in onInputProcessing
cha1 = request->get_form_field( 'ip_mrf' ).
where cha1 is the page attribute
hope this helps,
Regards,
Siddhartha

Overprint preview in Adobe Reader

Hello,
Is there a way to preview colour separations in Adobe Reader (overprint preview). I create Illlustrator files with overprint preview and save as pdf for my customers. When white is on top you can't see the other colours underneath.
Adobe Acrobat is OK with this because it has an option to preview colour seps.
Would appreciate a reply on this as my customers are not happy
Best Regards
Ron

Is there a non-confidential example of this PDF that we could view?
