Create thumbnails and pdf low resolution

We have an archive of 3000 + PDF in high resolution, ready to print and new come every day.
Some of them are 80 + Mb in size.

We want to put these available for download, but in low resolution.
Can someone tell me how I can

-Downsample pdf high resolution low resolution as PDF files, have 72 dpi images.
-Excerpt from the first page in PDF in low resolution.
-Create thumbnails of the first page, in jpg format, width: 200px.

I tried many solutions already ghostscript iText, acrobat pro, pdf2image and cfx_pdf.
All of these programs seem to give nice results at first sight, but all have let me down.
They cannot manage jpeg2000, add borders and invisible to the pdf layers, etc.

We are working currently with automate and acrobat pro, but acrobat crashes all the time.

We are looking for something reliable that we can run ColdFusion with Java/COM or command prompt.

I'd like to hear your comments, thank you in advance.

Hello

I found the solution I was looking for.
I'll post here so if anyone has the same problem, it doesn't have to waste time, I did.

You will need 1 program and 2 plug-ins, all of them are not free to say the least.
-Adobe Acrobat Professional
-A box of stuff ( http://www.quite.com/box/) -200 EUROS
-Autobatch ( http://www.evermap.com/autobatch.asp) -120 EUROS

These tools allow to downsample a whole repertoire of PDFs from the command line (CLI) at 72 dpi.

You can create a 'batch' with "a box of stuff" so it won't be to downsample the images in a PDF document at 72 dpi.
Autobatch is a program that creates batch (.bat) files that run in "batch processing" in acrobat professional.
ColdFusion can run this batch file, and you can create a scheduled task to do it regularly.

However this solution only works on Windows and Mac.
You must run a free operating system, write a letter to Adobe to convince them to free Acrobat professional on linux, * BSD, whatever. Because they should.

Best regards

  • Look at pictures of press pdf low resolution

    Hey,.

    I wrote a pdf of press of an Indesign file made up of photography. He was wonderful as usual. But I imported the same content for a resizing and wrote a new pdf press and photo of the pdf part looks like very low resolution. I re-imported the photos and tried again. But now I am at a loss. Someone help please?

    As you find it, a lot depends on how you create the PDF file. I guess it isn't with the option to export in ID, Acrobat. When you change the size on a bitmap, a change of resolution in PDF format can cause a lot of problems because of the way the original bitmap can be sampled and put in the new resolution. Always a danger when playing with scaling of bitmaps (why vector graphics are preferred where appropriate - of course, not for photos and others). I suspect that all goes back to the sample which is forced. In the future, you might want to to scale the chart in an appropriate program (perhaps PhotoShop) to obtain the desired size and resolution and use in the presentation of the ID, not just a copy, paste, scale. Graphics programs are properly designed scaling a bitmap.

  • 5.5 InCopy user cannot save to PDF low resolution

    The user complains that they can only save as pdf high resolution pdf not low resolution.

    Is there a way to do this in InCopy?

    Harlan

    InCopy users have not 'res pdf' control... it downsize images to 150 dpi, which I think is more a "res intermediary." Images that are less than 150ppi initially are left as is.

    The only way to get the images to a smaller resolution is to open the PDF file in Acrobat Pro and do a Save optimized As it or to reduce file size.

  • workaround for the slowdown in performance and the low resolution of the RED R3D files after effects CC 2014 (13.0)

    ml http://blogs.adobe.com/AfterEffects/2014/06/Red-R3D-Problems-After-Effects-CC-2014-13-0.HT

    The After Effects team are investigating a bug in after effects CC 2104 (13.0) when RED (.) R3D files) are very slow and the resolution of the images is poor, all sampling of 1/8.


    The following workaround solution was reported to solve problems in some cases:

    1. Save the project.
    2. Choose Edition > purge > all memory and disk cache.


    Please post in this thread on whether or not this work around has helped you.

    Performance issues and resolution with the RED (.r3d) files have been fixed in the CC of effects after update to 2014.1.1 (13.1.1).

  • Gradients and PDF frame edge problems

    I have a document that contains a series of bottles of cutting on a gradient background.

    If I print this document to a color printer, it seems.

    If I print to PDF, however, all the contours of the block appear (that is, the contours of the block of the cutting cylinders). If I lose the gradient, this problem no longer occurs.


    Someone can you please explain how to solve this problem (and why it is happening at first)?

    Thanks in advance.

    In rereading the post, can I have misinterpreted what you said originally (a screenshot is a wonderful way to show us what you're talking about). I thought you said the transparent background area showed as a different from the rest of the background shade, but I realize now that's probably not what you mean at all.

    First turn off we're going to try to get more details on the file and the final outing. This will display a press or digital? Are the Spot color or process?

    What are the settings you use to make the PDF? You said 'print' in PDF format, and if this is the case, you're flattening transparency and what you desbcibe as showing the outlines of the block would be thin white lines in the image inclusive. They are called "seams" and are a flattening artifact that displayed on the screen and in low resolution prints made since the PDF, but don't generally are not in press output.

    Print to PDF is a distillation process and ALWAYS made PDF with flattened transparency. It is best to leave transparency live as long as possible, ideally let RIP printer do the flattening. To keep the dynamic transparency, you must EXPORT it to PDF, not print (and starting in CS5 you for printed output, you must change the default value to [Interactive] PDF export as PDF [Print]) and using Acrobat 5 or greater compatibility. Presetting of the quality press is a good choice if you are going to press on and you control the color management on your end because you know the printing requirements (it converts all colors to process and a unique output profile). PDF/X-4 will preserve all the colors and incorporated to the RIP printer profiles for color management, but not all printers are up-to-date enough to handle this.

  • Embedded Fonts and low resolution PDF

    Hi guys,.

    I have Acrobat Pro 9. I've used Acrobat Pro 7 some time ago and it was great to have option of embedded fonts. I read that if I save the PDF file in high resolution (printing for example) fonts will always be integrated. The thing is I want to make a Low Res PDF for the Web but Embedded fonts so that everyone will see the Garamond type I choose or if they decide to print it, they can do it and maintain its design.

    Can I do this?

    Thanks for any info!

    See you soon,.

    SEBS

    In InDesign, just use File > export and choose preset for smaller file size. Which will integrate your fonts (the subsets that would be good enough) and reduce the image color resolution 100ppi.

    If you want it lower, like in Acrobat, go to the "Compression" settings and put them at a lower resolution it.

  • script to save .pdf with different presets generates the file size low resolution wildly different interactive operation

    The script below is adapted in part from that has been with Illustrator and other pieces and the pieces that I picked up the Forum.  When I run it on a 15.3 Mg .ai file it produces

    . The same PFS size that would be the case if I manually created at Headquarters printing and by default; but the low-resolution sort option to 9 Mg as opposed to the 439 K he "should" be.

  • logo JPEG to PDF display low resolution in reader but ok in acrobat DC, any ideas why?

    The appropriate image size should be set in Photoshop.  Let all the layers - especially the layers as kind and forms vector

    Then you must read carefully the options when recording in PDF format.

    On the Compression tab, ensure that the dpi is set at least 300

    Hello

    I have a P100-188 and fonts on the office and Internet icons display very well, however the fonts displayed in message boxes look terrible, looks like they are displayed in low resolution, you can see practically every pixel that make up the letters.

    Could be a hardware failure on the laptop.

    One thing to try as a test is to start from a 'live' as Ubuntu OS (for example), just start it DO NOT install it. See - http://www.ubuntu.com/download/desktop/try-ubuntu-before-you-install - for more details. This should hopefully allow you to see if the screen works well or not in another OS, if it looks OK in Ubuntu, then its less likely to be a hardware problem. But if the screen is still divided, then unfortunately, it could be a hardware failure.

    Other things to try eventually (in no particular order):

    1. set to update your graphics card drivers to the latest compatible drivers available for your laptop, where they have been corrupted somehow.

    2 - is still divided into 'safe mode' or is it OK to whom?

    3. If you look in Device Manager, it shows errors regarding the graphics/display/monitor card?

    4. There is this fixit - http://support.microsoft.com/mats/Windows_Display_Quality_Diagnostics/ - in the center of MS fixit who can be worth it. But I doubt it.

    5. If this just started recently, try a restore point for just before it occurred.

    Assuming that you have already tried to change the screen resolution and depth etc color settings and then restore the default values, you need.

    I created show and hide features in InDesign I want to export to interactive PDF format. These functions work when seen in Acrobat on the desktop, but not on iPad/Tablet - why?

    Why? Most likely because the PDF Viewer on the Tablet is too stupid to deal with show/hide functionality.

    You could try PDF Expert of Readdle on qpdf Notes Pro on Android and iOS devices.

    Depending on how the show/hide was created during the export of InDesign, it can work in viewers. Otherwise, you will need to open PDF files in Acrobat and edit features show/hide something more digests of PDF device viewers.

    BTW, you will encounter the same issues with the PDF display components in web browsers.
