Adjust Contrast in PDF files

Hello,
I have a huge searchable PDF file (300+ pages, 40+ MB; it is
a scan of an early 20th century book I need for my work at
university). Everything works fine, but the pages appear somewhat
too bright. It's hard to read them on screen.
Is there any way to increase the contrast of my
300-dpi-grayscale-PDF-file? I extracted some pages and edited them
in graphic software, just increasing contrast 20 %. The pages are
perfect now - but I am not happy about the perspective doing this
300 times, and I have some more scanned books that could need a bit
more contrast...
I tried to convert the pdf file to monochrome. But the result
does not look very nicely.
Thanks in advance
Zaphod

Adjusting contrast in a PDF document with multiple pages

I have seen a question asked several times in various forums and it never gets an answer: how do you adust the contrast and brightness of a scanned PDF if it has several pages? You can't do it in Acrobat, and there are no third-party tools that I've found that work. If you have Photoshop, there is a solution to the problem, which does not require adjusting every page in a document. I use a high-speed duplex hopper-fed scanner to copy books or articles I need for my school work (no, I don't violate copyright by giving them away). There is no way to adjust contrast at the scanner level, so I end up with a 700-page document that is too light or too dark.
1. Use Acrobat to extract all the pages to separate files.
2. Use Adobe Bridge Tools>Rename to serially rename all the pages, so that Photoshop sees them in the right order and they can be reassembled later. There are other free or cheap tools for batch renaming that work equally well.
3. Experiment with your settings on a sample page in Photoshop, until you find one that works. I usually use auto-contrast, or adjust the curves myself.
4. Perform whatever other manipulation you need to on the document page, such as resizing or changing mode to greyscale.
5. Create an action following the same steps.
6. Run a batch process on all the pages in your undone folder, saving them to a done folder. Override the Open and Save settings to avoid dialogue boxes and so on.
7. Reassemble the document from the individual pages using the Combine function in Acrobat.
I use this method frequently, making small adjustments to the action as necessary. It takes a while to do a large document, but it solves a lot of problems. One problem that is very hard to solve, however, is caused by scanning cheap paper, which makes the scans come out blotchy and grey, and very hard to re-contrast without losing resolution. Acrobat can help solve this problem sometimes with the Optimize Document functions, but in general, it's easier to scan better, whiter paper than rescue it later. One solution is to scan only one side at a time, and then use a third-party PDF tool to interleave the pages.
If you have a lot of documents to do that can use more or less the same settings, create a Droplet macro in Photoshop and drag your page folders to it, instead of running a batch.
Hope that helps.

Thanks for posting your solution.

Adjusting brightness of graphics in .pdf files.

How do I adjust the brightness level of my color graphics in my .pdf files in Acrobat 9 Pro? All graphics are printing way too dark. Printer is a brother 9840 MFC color laser. Thank you.

The color on your screen will never agree with the color printed. The
colors you see on your screen are formed by using combinations of Red,
Green and Blue (RGB). The colors when printed are usually made from the
colors (Cyan, Yellow, Magenta, and Black---called CMYK). The colors made
on your monitor are from combining light of different colors. The color
on a page is formed by combing toner or ink to form different colors.
If you use a color postscript printer the colors will be printed using a
CMYK model. A cheap inkjet printer will try to use CMYK, but for the
most part it is faking it.
It is very complicated to get good color reproduction. The steps involve
calibrating your monitor and your printer, so that your software knows
something about how the colors on your monitor and printer look. This
discussion is way beyond my ability to communicate effectively. Color
management is very complicated and fortunately, my work has never
required high fidelity color work.
Perhaps, someone can step in to recommend some reading that can lead you
in the right direction.

I have to zip pdf files to email them to someone with a PC. The problem is they aren't smaller after zipping and I can't email them. I tried adjusting the Quartz filter to the Reduce file size. Now they're smaller, but the recipient can't read them. Help!

I need to zip pdf files to email them to a PC user. The problem is file size is not reduced.
I tried zipping them in Win 7 (which I use via Parallels 7) and sending them to the Finder to email.
But lately nothing is reduced. I tried choosing the Reduce File Size option in the Quartz Filter when I save the doc. The file size was reduced. However, the recipient could not read the file. Everything was blurry.
Is there a solution?

I am having some PDF sizing issues also, I am a BETA tester for TurboCAD Mac, and with the usage of (public) version 5, I have had some scaling issues. I have had (auto sent) 15 plus crash reports, (available as text) and had posted my scenario within the "lion- problems so far" article, so not to use up extra bandwith- or whatever- there are pictures there. I was not able to upload a PDF on site, and the staff @ Turbo CAd is working on it also. this is Lion specific new update, as I have posted many large format PDF's

How do I scan multiple pages into one pdf file using the PIXMA MG7520 on Windows 8.0? Please help!

I recently received a PIXMA MG7520 for a gift. It works great with my lenovo laptop/tablet running on Windos 8.0. The one drawback to the HP all-in-one that it replaced is it does not have an ADF. That being said, there must be some way to scan multiple pages into one pdf file. I need help figuring thing out. Thanks in advance!
Solved!

Hi mdtolbert54,
There is a program that comes with the printer called the IJ Scan Utility that can assist you with scanning multiple pages into a single PDF document. To do this, please follow these steps:
1. On your keyboard, press the Windows key.
2. Start typing IJ SCAN UTILITY. The search window opens as you type. Once the IJ SCAN UTILITY is displayed, please select and open it.
3. In the Canon IJ Scan Utility window that opens, click SETTINGS.... in the bottom right of the window. The Settings dialog box appears.
4. Click the DOCUMENT SCAN option on the left pane of the window.
5. In the SAVE SETTINGS section of the window, you will select the save format and location of the document you are about to scan.
a.) In the FILE NAME field, specify the name you would like to give the file. By default the filename will begin with IMG; you can remove IMG and change it to whatever you would like to name the file.
b.) In the DATA FORMAT field, use the drop-down arrow to select the PDF (Multiple Pages) option.
c.) In the SAVE IN field, please navigate to the area where you would like the file to be saved once it is scanned in. By default, the file will be saved in the MY DOCUMENTS folder.
6. Once all settings have been selected, click the OK button at the bottom of the window to save the changes. The IJ Scan Utility main screen appears.
7. Click the DOCUMENT button. Scanning starts. Click the CANCEL button to cancel scanning if needed. Scanned items are saved in previously selected folder location specified in the SETTINGS... window.
If you find that you need advanced scanning options such as adjusting resolution, brightness, contrast, saturation, color balance, etc. in addition to the options selected above, please click on the SCANGEAR button on the IJ Scan Utility Main screen, then adjust the items as necessary.
Once the items above are set for document scanning, in the future, you will only need to launch the IJ Scan Utility, then press the DOCUMENT button to perform the scan (unless you want to make changes to the settings).
Hope this helps!

Adobe 9.1.3 and FireFox 3.5.1+ "...can not be used to view PDF files in a Web Browser"

This is the issue but I'm not sure there is a resolution:
Firefox: Version 3.5.1
Adobe: Version 9.1.3
When navigating the web, click a URL that opens a PDF inside the browser and you get an error * "The Adobe Acrobat/Reader that is
running can not be used to view PDF files in a Web Browser". Please exit Adobe Acrobat/Reader and exit your Web Browser and try again". I did read a post that doing a "repair" from the Adobe Reader application should fix this, they also reference a few registry keys to check becuase the post states it's lost the application path to Adobe version X. I don't necessarily buy that "fix" and here are my details below.
In FireFox if you navigate to Tools > Options > Applications > Adobe Acrobat Document
You're given choices:
Always ask: DOES NOT WORK, produces afore mentioned error *
Save File: Works, saves the file to a directory on your PC
Use Adobe Reader 9.1 (defau...: Works, opens your PDF's outside of your web browser
Use Adobe Acrobat (in Firefox): DOES NOT WORK, produces afore mentioned error *
Use other...:
IE seems to just work as expected.
If you open Adobe Reader > Edit > Preferences > Internet > Check "Display PDF in browser" - DOES NOT WORK, produces afore mentioned error *
This would seem to be an Adobe error rather than a FireFox web browser problems since FireFox does seem to know the correct path although I suppose you can't rule out that this is a FireFox problem since 2 out of the 4 PDF open options DON'T WORK.
Any thoughts on this issue would be greatly appreciated.
Other information:
Adobe 8.1.5 works perfectly with FF 3.5.1+ when opening PDF's in the web browser, we also had no problems with previous versions either.
MSI push via Active Directory from Adobe 8.1.5 upgrade to Licensed Distribution I signed up for, Adobe 9.1.3 which was upgraded from 9.1.0, to 9.1.2, to 9.1.3 via an MSP patch.
Operating system: Windows XP SP 2, plenty of RAM, plenty of Drive
IE version this works with the new version of Adobe 9.1.3 is version 7 (7.0.5730.13)
Our FireFox MSI's come from Front Motions website and as far as I know we've never had problems with their MSI's, also tried the new release of FF 3.5.2 from their website.
I think that about covers it. Anyone else experiencing the same problems or have a patch?

After troublshooting this for the entire day today the issue seems to be a MIME problem.
If everything is woking perfectly, in Tools > Options > Applications...
You should see 4 or more things related to Adobe like "Adobe Acrobat Forms Document", etc. If you don't see at least 4 MIME entries either your Adobe installation is hosed or your FF installation is hosed. I haven't figured out which is causing the issue.
What I did was remaster my patches from my original Adobe 9.1.0 MSI with the two updates via the command line in the directories with the source files. On the 9.1.0 original file I first remastered my MST transform with the Adobe MST utility. I then applied my patches.
msiexec /a AcroRead.msi /p AdbeRdrUpd912_all_incr.msp
msiexec /a AcroRead.msi /p AdbeRdrUpd913_all_incr.msp
I then uploaded that to my network share, unlinked my group policy, made a new group policy, added a batch file to delete adobe.com from program file and the desktop on system startup even though my MST was supposed to take care of that - it's not a perfect world is it? :-)
I then reapplied my GPO's for both FireFox 3.5.2 and Adobe 9.1.3, I checked to make sure the MIME extensions were there and they were. You might have to go into your Adobe Preferences and select that open in browser setting depending on what happens or adjust your MIME settings in FireFox's options but it should work.
That's what worked for me. It's possible a few other things I did along the way tweaked it out, in my group policy on the first run I did select to upgrade previous group policies, for the remaster and repush I didn't select any previous GPO's to upgrade.
It's hard to tell what one thing tweaked it out or what combination of things tweaked out the install. I did also reinstall Adobe 8.1.5 and FF 3.0.10 before doing all this since our machines currently have that setup, I'm not sure if that affected it either, it's just hard to tell but I don't think it did simply because I had done that several times in troubleshooting this issue.
If anyone else has more specifics that would be great!

I use iMac desktop. I can't save web pages as PDF file by using Firefox, but by Safari is fine.

I'm using Mac OS X 10.6.4. Today, I tried to save my email content as a PDF file. However, I only got a PDF file that have partial content of email. Then I adjust the printer setting and did it again, then I only got a blank PDF file. There was nothing inside. Then I tried to save email as a PDF file by using Safari browser. And I got a complete and sucessful PDF file. I usually save web pages or web mail, online receipt as PDF file by use Firefox. But since I have updated to the new version, there were many problems with my Firefox. I tried to restore all my application and made Firefox in the old 3.6.3 version which I used to have no problem. But now still not working.

I solved it for myself: it was my HP smart-web printer crap that was a plug in and add on for firefox that somehow automatically got installed when I upgraded to 5. I disabled both in the add-ons manager, and voila, printing is working.
It seems there are many things, like this and the Google toolbar, that were screwed by the oddly fast update to 5. Looks like Mozilla didn't give anybody any notice! Must've been some really bad security hole.

PDF file doesn't view properly in firefox & favicon doesn't show in Safari

I've got three issues I could use some advice with.
1. I used some iFrame code generously posted by Oldtoad that allows a pdf file in an IFrame. It works beautifully in Safari. here's an example: http://web.mac.com/phelpssculpture/Site/resumeone_page_DavidPhelps.html
but in Firefox it only opens as a dialog box asking what I want to do with the file (download, etc)
Is there any way to make this view properly in Firefox?
2. I've gone through the process to have a favicon in the address box (ico file uploaded with iTweak) and this views great with Firefox, but nothing in Safari (not sure about others) I've deleted the WebpageIcons.db file repeatedly, emptied cache, deleted all my bookmarks for the site, etc.
Anyone know how to make this work in Safari?
3. I recently updated my site (from iWeb 06) using iWeb 08 and published. A lot of search links got broken. I created a new sitemap (verified by google) and now, no matter what page a search refers to, when you click on it, only my home page opens. Did I do something wrong? It used to be that if a search pointed to a certain page, clicking that result took you directly to that page.
Any suggestions for these problems would be greatly appreciated.
Thank you, David

Old Toad:
I finally got it! the favicon works now at: http://web.me.com/phelpssculpture
Your Instructions at:http://toadstutorials.info/ #22 did the trick.
One problem I had with TextWrangle was I was doing a search and replace for <head><meta and it wasn't working. What I figured out was that there was other code on the line after <head><meta which was preventing the new code from working. I did a minor adjustment on each page in iWeb to force it to republish each page. That made the <head><meta line consistent on each page, then I selected the entire line and replaced it as per your instructions. It worked great. My experience was that iTweak did not process the code properly and was very slow, but this process was great.
Thank you for all your help. Sincerely, David

Create a single tall image from a multi-page pdf file

I would like to take a multi-pake pdf file, and have all of the pages "appended" from top to bottom edge to create a single tall image. I am a teacher, and I currently do this by hand, I am then able to annotate the entire page and croll down an entire document inside of Photoshop.
Here is an example: I have a pdf with 4 pages. Currently I open the pdf in PS, I end up with 4 images; I adjust the vertical canvas size of one of the images to be 4 times it's original size, then one-by-one I copy the contents of each image to that new tall image and move that layer vertically below the previous one. So the result is say a 1024x6400 pixel image.
I would like to be able to just open the pdf with a script and get this all done in one step.
Any help is appreciated.

Thanks again c.pfaffenbichler. I had most of it worked out in my own way before you got back to me, but I wasn't able to get the final naming part down.
Like I said, I am a math teacher, and I use photoshop as my whiteboard, and draw with a graphics tablet. So I can print to pdf from any program, now I can import any document into photoshop basically to write on it. So this is wonderful. I have never seen another teacher use PS as a whiteboard in class in this way, so I am most likely the only person in my county or state that would need such a script.
After I got everything worked out, I added some things to the script. Some of my colleagues will use my files as a whiteboard if I send it to them as a tall single page pdf that they can scroll down and write over; so they don't need photoshop. So I have scripted in the saving of that pdf as well. Here are my changes; most of what I changed is in the section commented MY WORK.

Printing several pages from a single page pdf file

I have a pdf file single page of a schematic diagram illegible at A4 (so much information); viewable in parts on screen with zoom and loupe tool. How can I separate the diagram and print at a legible size on separate A4 sheets .

Use Preview .app
Open the first jpeg in Preview and:
+Menu > Tools > cmd A (select all) > Adjust Size > Click on Padlock to unlock > Measure: Pixels > Fit into: Custom > Uncheck Scale proportionally > Check Resample Image > enter 3x height and keep resolution the same+
You should now have an 3 times as high but distorted.
Paste the 1st image back into file and slide it to the top.
Copy and paste the 2nd and 3rd images and move them into place.
Resave with a new name.

When saving a PDF file, it saves multiple of the exact same documents, why/or how do I change those settings?

When savind a PDF file, it saves multiple of the same document, why? Are there settings to adjust or what am I doing wrong?

This might help - I'm not sure:
Go to System Preferences (under the Apple logo in the menu bar). Click "General" and check "Always close windows when quitting an application."

PDF files merging on print command from windows desktop

Hello,
I have an application from which I want to genarate PDF documents. The application is installed on my personal desktop. To test the process, I downloaded the Adobe PDF converter driver (free download version) and installed the same on my PC. I used control panel to change my deafult printer settings on my PC as this new PDF converter driver.
Now I logged to my application , where I can select the list of documents to be printed. The application always uses default printer of the PC on which its installed. Hence all the documnets got created as individual PDF files on my desktop. This was great.
However my ultimate requirement is when I select a list of documents using my application and give it for print at one shot, all the documents should come as a single PDf file rather individual files. Or else you can define my requirement as any no of dcouments given for print at one go (or one session) must be generated as 1 single PDF file. Is it possible to adjust the PDF converter driver in some way to accomplish this
I made further investigation into this and found Adobe Acrobat pro 9 is a good software to generate PDF. Will purchasing this and installing this s/w solve my current problem. Please advise.

Hi Leonard,
Thank you very much for your prompt reply. The answer has not solved the problem yet. My users don't want to manually merge the files. They want it to happen automatically.
The application which prints documents is a simple MS access database. This is available on users personal desktop. As soon as the user opens the MS access, it is programmed in such a way that, the access database runs as a program. It uses DSN to connect to the sybase database and get the details of documents that are pending for print.
At this point MS accesses database starts an itretive process, fetches the data from sybase , calls the correct report template in MS Access , populates it and prints the report using the default printer on which the database resides. Thus it prints the document one by one. By setting the default printer to Adobe PDF converter, we were successful in creating PDF documents rather than printing to paper , but the disadvantage was each document got printed to one file each.
The whole process is coded as VBA module of MS access. my question is by using an API from Adobe SDK, will I be able to make changes in the VBA code of MS access database so that all files requestd for print comes out as a single PDF file.

How convert a color PDF File to black & white (gray scale...no color)

How convert a color PDF File to black & white (gray scale...no color)??? creative cloud cs6... Acrobat etc

Hi, just wanted to add my 2¢
I've been in publishing over 25 years and live in Acrobat for making my final files. Currently with a newspaper.
This is what we do:
• Tool Panes > Print Production Window
• Select CONVERT COLORS
• Midway down under OUTPUT INTENT, check Convert Colors to Output Intent
• In the associated drop down menu, I choose (because I'm printing on newsprint) DOT GAIN 20% – If you're working on better stock, choose a lower dot gain percentage.
• Click OK – this will convert the file
• Save
Note: this affects the file you're working with. Make sure that you use this method on a COPY if you want to retain the original color version.
I think if you compare my method to the Preflight method, you'll see a tighter contrast and better blacks. I've always felt the Preflight method left continuous tones a little muddy.
Now if there was only a way to add that to ACTIONS...!

How does I resize a pdf file page using Acrobat Pro?

In Acrobat Pro, how can one resize a pdf file page (21.38'' x 26.75'') into one measuring 6'' x 9'', to be submitted as the trim size? Is there a feature that allows this to be done? How does one set all print options from the Application print dialog box to enable one to adjust the dimensions of any customized file page?

I want to scale the 21.4'' by 26.8'' content down to one that can be fitted inside a 6'' by 9'' book.
I have this pdf that was created from the InkFlow app, and I'm using Acrobat Pro to merge three files into one (about 300MB), which I needed to submit to Amazon's CreateSpace, but they needed the trim size of 6'' by 9'', while the pdf is 21.4''' by 26.8'', and I can't amend the source file size of the InkFlow files.
I tried fiddling with the Crop and Print options, but I'm unable to resize the pdf to match the trim size. The problem on my side isn't so much on printing but to resize the pdf file page to 6'' by 9'' to satisfy Amazon's requirement for their trim size. Could this be done with Acrobat Pro? The message that appears is: Full print options of Acrobat Pro, set all print options from the Application print dialog box. Thank for the help.
