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 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...

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?

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 is on by default

All of a sudden the Overprint Preview is one when I open a document. How do I turn it off by default> This just started after several years of InDesign work and I can't get it so turn off. Any Ideas? Thanks. AZturtles

Hi Peter
Thanks for the response to me question about Overprint Preview in InDesign. The attached screen capture will illustrate what happing with the text. I can toggle on/off with the View>Overprint Preview but it is always on when I open the documents. Does this screen capture help define the problem/
Oh, by the way, InDesign is registered to my wife so perhaps you could answer to [removed by forum host] She works for Arizona State University and gets the Adobe products cheap but we must register them to her.
Thanks

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 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?

Overprint Preview, RGB, Image Resolution Acrobat v9

I recently started using Acrobat 9. There is 2 things I'm looking in V9.
1- Overprint Preview
2- All image resolutions in a HiRes pdf. I see a custom check profile called "resolution of color & grayscale images is between..." but I want image resolution is ...
3- Flag any RGB images used.
ThankYou

I'm sorry what I mean if a pdf have 35 images I would to see the image resolution of all of them independently if they are 72 or 600 dpi.

Quick keyboard shortcut to show Overprint Preview

The old Command+Shift+7 to toggle Overprint Preview doesn't seem to work in Acrobat Pro 9. Is there another way of quickly toggling this function without having to enter Advanced>Print Production>Output Preview?

Wow, guess I need to reinstall Acrobat 8 because it makes for a faster production tool. I thought I was upgrading. Guess I'll never see the logic or reason in the things Adobe does when producing new versions.

Modify PDF documents to activate the "overprint preview" the document opens in Acrobat 9 / X

Hallo ,
I would like to modify PDF documents that the document automatically activate the “Overprint Preview” option if they opened by using Acrobat Reader, Acrobat Stand. or Acrobat Prof. Version 9 or X.
It is important that it makes no different what is selected at the General Preferences settings (K+STRG)--> Page Display --> “Use Overprint Preview”.
It is possible that the PDF File / Data change the settings to “always” at the General Preferences --> Page Display -->“Use Overprint Preview” settings.
Has anybody a good idea to solve this problem?
Thanks for our help.
Ralf

I had the same problem and my solution was to disable the PDF extension that came with Firefox 4 which belongs to another company. I found out that it wast interfering with ReaderX. I unabled it and restarted Firefox. I have had no problems since then. Go to Tools, Add-On and click on Extensions and disable the PDF extension. I hope this helps

InDesign crashes when i export a pdf, overprint preview and package

I am using CS6 on a MacBook Pro. I have version 10.8.5.
I am working on a manual (original file not created by me).
I was trying to pacakge all the files together but it kept crashing. I do not see the blank window some people have been seeing when this happens. I only get the window about letting Apple know about the problem and submitting the problem to Adobe.
Under Preflight all systems are fine, I have the green light.
I checked that paragraph styles, character styles and master pages did not have fonts missing.
I went through all files and noticed some eps's did not have fonts converted to outlines so I made them outlines and relinked them.
I also changed all RGB to CMYK.
I converted the file to an IDML, reopened InDesign. I also resaved the file to a different name.
These did not seem to help unfortunately.
If there is no visible problem, what can one do? At this point I am trying to pdf one page at a time to see if I can pinpoint as to where the issues lies.
InDesign also crashes when exporting a .pdf and when I try to run an overprint preview. So strange..

Well I don't get why this would have been the problem, but I removed the logo that was on the cover and on the back. Since the logo was all vector, I copied it and pasted it into InDesign (so no links). This allowed me to create a .pdf and to package. This logo has been used several times over and over so not sure why this was part of the issue..

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.

Overprint preview acting up?

All my content is in 300dpi, but overprint preview will show everything as pixilated and put a grid on my page. I'm wondering why that is..

Could be as simple as a corrupt pref file. Let's try easy first...
Quit Preview. Go to Users/yourname/Library/Preferences/com.apple.Preview.plist and trash it. Relaunch Preview.
Any better?

Overprint / Transparency Question

Hi, all. I'm working on a logo which will need to be separated for 2-color offset printing. To produce shading effects, I've created a solid black shape to which I've applied a black/white gradient as an opacity mask. I've set this piece over an identical shape filled with a PMS blue. The idea is to overprint the black ink as a solid-to-transparent gradient over the blue solid to produce the shading. When I set the black gradient to "Overprint Fill" and view the logo in "Overprint Preview" the result looks great on screen. The design also features a hard bevel, the dark edges of which are produced by placing semi-transparent shapes filled with black and also set to "Overprint Fill".
However, when I go to save the file I'm presented with a warning about how using spot colors with transparency can "generate unexpected results". In the save dialog box there is also a message that says "Overprints will not be preserved in areas that interact with transparency". What does all of this mean for my poor little logo when it goes to press?
Here's an example of what I'm trying to achieve. The highlight is a simple gradient from white into the blue, but the shading is performed as outlined above. Any insight would be appreciated. Thanks!

The way I understand it is he is using a Black gradient over Blue. The White can be White, but in this case, probably 0% Black will work. The Opacity Mask is probably considered "Transparent" along with the Black bevel elements, hence the warnings. I wonder if those elements can be left without transparency and set to "Overprint Fill". For instance, a 30% Black on a single bevel element could be set to O.P. with no transparency settings. There will be no screen view of the effect, but it will separate as a 30% Black overprint. Same with the gradient. It will not preview with the effect, but will separate as a Black gradient set to overprint ( no Opacity Mask necessary ). Or, keep everything the same except apply "Multiply" in the transparency setting ( along with Overprint Fill in the Attributes dialog ). This gives you the preview of the effect, but the nagging warnings.

Overprint preview + white ink = trouble

Is there _effective_ and _efficient_ way to preview % tints when artwork ink is lighter color than background paper/shirt/etc.? (Have same prob in Illus and InD.) This prob is similar to other threads but not quite same issue, I believe.
Examples: (1) Vector t-shirt art, one color ink (prob opaque white) on darker shirts, or (2) silver ink on black cover stock invitations.
First -- I clearly understand diff between tint % and transparency, knockout, overprint, "paper" color vs. white spot ink, etc. When designing and working with black only (K), we can use "inverse" color to simulate look for client approval.
BUT when creating document correctly, 30% tint of pale color spot doesn't "look" grey in overprint preview, as 30% opacity in transparency field does. Worse yet, if _both_ transp and tint % used in design phase, then essentially needs flattening before output; but want to preserve vector shapes so as not to interfere with printer's screens/angles, etc.
Am I missing software feature I should be using instead? Appreciate any suggestions,
--romy
Lo-res from screenshot attached, as example.

I fully understand your problem. Does an opacity mask help?
Say you have a black background (the colour of your t-shirt which you can keep on a back layer, locked so that it's out of the way).
Now (on a top layer) do your tonal stuff using black and percentages of black.
Behind that (also on the top layer) make a rectancle of spot white that comes underneath the black artwork.
Now select everything on the top layer and in the Transparency palette hit on the little button at the top right of the palette and select Make Opacity Mask.
Reverse the mask as required.
Reckon that ought to work and I don't think you need to flatten anything.
