Web compliant colors in PDF files – how to reduce errors

Jani / Tips and tutorials / January 9th, 2012 / 20 Comments »

We know you love using FlipSnack to create amazing flipbooks, so we try to make every app as simple as we can, but sometimes it’s not up to us to make everything run smooth.

Most of the issues people have with converting PDF files in FlipSnack or SlideSnack are due to the color format of the file. Some programs are quite old and will not create web compliant PDFs.

This tutorial will show you how to fix them. First of all you need to get Adobe Acrobat X Pro – you can either buy it or download the trial version.
After the installation, open the troublesome PDF in Acrobat X Pro and do the following:

1. Click FileSave AsMore OptionsPDF/A

Reduce PDF file size

2. Click Save (you can overwrite) – please be patient, this may take a few minutes.

After this step you may or may not get a message regarding PDF/A standard compliance; if you do not get the message, your PDF file is fixed. However, if you do, please continue with the steps; also, if you experience problems with this step, please go back to Step 1 and try using PDF/X instead.

    Hi! Thank you for your wonderful customer support and laymans terms in the FAQ! My question is, I created a page in my PSE, but there doesn’t seem to be an option to save it to PDF format. How can I create a PDF format?

    Hey there Amy,
    Thank you for your very nice comment.

    Here’s how you can save your work in PDF format:
    1. In the Edit workspace, choose File > Save As, and choose Photoshop PDF from the format list.
    2. Specify a filename and location, select file-saving options, and click Save.
    3. In the Save Adobe PDF dialog box, select a compression method.
    4. Choose an option from the Image Quality menu.
    5. To view the PDF file, select View PDF After Saving to launch Adobe Acrobat or Adobe® Reader (depending on which application is installed on your computer).
    6. Click Save PDF.

    I installed adobe pro 11. I made all the process explained in your FAQ. Adobe report says everything is OK and still I got :

    File essai_rencontre2.pdf couldn’t be saved. Invalid type

    Have you any idea ?

    Thank you for your answer.

  6. Jani says:

    Hi Philippe,
    Unfortunately, I can’t help you myself, but please contact our technical support and they will help you (contact[at]snacktools.com). Thank you!

  7. Rachel says:

    My pdf just got 147 pages~ However, after uploading the pdf, it states that i have 1670 pages (exceed 150 pages limit).
    I have no idea on this.
    How can I fix this problem??

  8. Jani says:

    @rachel Please contact our support team: contact@snacktools.com and we’ll check your PDF to see what’s causing that error.

  9. Leah says:

    Hello! I have a quick question about the search option. Do you have to enable optical character recognition on your PDFs before you upload them? ie if I’m scanning a page of a book, I have to use OCR so there’s actually text to search, right? Thank you!

  10. Jani says:

    Yes Leah, you are right. You need to have actual text in your PDF to be able to use the search option in FlipSnack!

  11. Kathy says:

    I’m not able to upload my PDF using Acrobat 9 which is the same version I used successfully last year. Must the Acrobat be new than version 9 to work?

  12. Jani says:

    The acrobat 9 shouldn’t be a problem. Please contact us via live chat and we will be able to ask you more details and help you fix the problem.

  13. Bill O'Brien says:

    My PDF files are not stored in my photos folder on my smartphone so I cannot access them to upload them, nor can I drag and drop in iOS8 that I know of.

    How can I convert a PDF on my phone?

  14. Jani says:

    I’m sorry Bill, but the FlipSnack app doesn’t work on mobile devices yet…

  15. FLO says:

    I’m exporting a pdf straight from an InDesign file in PDF/A or PDF/X, my file is still invalid (176 Mo).
    It says (among other things) that my font is not true type, my pictures are in72dpi CMKN, etc. Do I have to switch to JPGs ?

  16. Jani says:

    Hi Flo, please contact our support team via live chat or by email: contact@flipsnack.com

  17. Rusty says:

    Does your software support MS Publisher 2007?
    My newsletters are about 20 pages in PDF but remain under 5 mgs. Will this be a problem?
    Your FAQ says a limit of 15 PDFs or pages?

  18. Jani says:

    Hi Rusty, at the time we only support PDF, JPG and PNG files. If you sign up for a free account, there will be some limitations on your account: you will only have 1GB of storage and we will only display the first 15 pages of your newsletters. So if your newsletters are 20 pages long each, you will be able to upload and publish them, but your readers will only see the first 15 pages. There are other limitations as well (like watermark, limited statistics) for the free accounts.
    By upgrading you will get rid of all of these limitations.

  19. Nicole says:

    Hello! The last few times I published something on Flipsnack, it completely changed my dark colors to neon versions of themselves. Can you explain why it did that and how I can fix it?

  20. Jani says:

    Hi Nicole, thanks for telling us. Could you please email us one of your problematic PDFs, so we can check the issue: contact@flipsnack.com ?
