How to flatten and secure PDFs in Adobe Acrobat DC Pro; simple
step-by-step.
Flattening prevents
others from lifting material such as clip art, out of the PDF. Securing prevents others from editing the
PDF--a must-do if you create products for the internet.
If you can select, copy and paste
pictures or text from your PDF file, it is not flattened and secured.
Please let me know if you have any
suggestions or improvements. Thanks so much!

Faint
White Lines – PROBLEM & SOLUTION
Sometimes, after flattening, you will see
very faint white lines. These can appear in a box shape around your clip art
images or text boxes—often only on your cover page.
When you print, these lines will not show
up.
You CAN, however, erase the lines from
your PDF. The solution comes from Adobe:
Solution 1: Export as PDF 1.4 or
later.
In the Export Adobe PDF General settings,
select Acrobat 5 (PDF 1.4) or higher from the Compatibility options.
Solution 2: Turn off the Smooth
Line Art option in Acrobat.
1.Choose
Edit > Preferences (Windows), or Acrobat > Preferences (Mac OS) to open
the preference dialog box.
2.In
Categories > Page Display deselect the option Smooth Line Art, and then
click OK.

About Adobe:
Adobe Acrobat Pro DC is the best program, by far, for flattening and securing PDFs.
If you're a teacher or student, you can save quite a lot by buying the Student and Teacher Edition. Here's the Windows or Mac version. You can upload it instantly, and begin using the trial version for a month before you must confirm your teacher/student status:
IMPORTANT: Please read the verification process carefully
before you purchase. If you do not qualify for Teacher or Student
status, you will be obligated to pay the full price.
Special thanks to Laurah J for her
cool video on securing PDFs.
Special Notes for Preview Files:
Many preview files when flattened, become too large to upload to TpT. The solution I found is:
1) In Flattener Preview page, Preset: Low Resolution, and Compression Settings/ Quality: Minimum.
Be sure to change these back to High Resolution and Maximum for the actual resource (that is, not a preview).
2) When Saving the Final Preview: File/ Save As/ Reduce File Size (tiny check box at the top)/ Choose Folder/ [Type: File Name PREVIEW +]
If your Preview file is still too large…
2) Upload
the file, compress it and download it.
3) Repeat
the steps 1 and 2 in Preview Files section above, to flatten and secure!
Also, for Preview Files: In your password
security > settings > change settings > printing allowed > [select NONE]
MUST:
Change BACK to “High Resolution”
for a printable resource!
