How to set security for exporting PDF on PS

The security settings for exporting PDFs on PS can be divided into the following steps: Setting the opening and permission password, and controlling the opening and operation permissions. Add digital signatures to PDF files to prevent tampering and verification of author identity. Adjust compression levels as needed, weighing file size and image quality. Embed fonts to ensure that the fonts are displayed normally on different systems. Select high-quality export settings to avoid blurry pictures or distortion of color.

Today, let’s talk about the security settings when exporting PDF on PS. This is a technical job and cannot be careless! After all, your design works are all the fruits of your efforts. Many friends only know how to export PDFs, but ignore the security settings. This is like building a house only to build a main body, but forgetting to lock the door. It is very risky.

Let’s talk about the most basic one, PDF password protection first. When exporting PDFs in PS, you will see an option that allows you to set the open password and permission password. Opening a password, as the name implies, is the password you need to enter to open a PDF file; the permission password is more advanced, and it can control the user's various operations on PDF files, such as printing, editing, copying, etc. When setting permission passwords, you can choose which operations are allowed and which are not allowed, which is very flexible. Remember, when setting passwords, be sure to choose a password with high strength. Don’t use a weak password like “123456”. It will be easily cracked and your efforts will be in vain.

Here is a tip: After setting the password, you must test it yourself to see if it can be opened and operated smoothly, so as to avoid the inaccessible file due to errors in password settings. Many friends will ignore this step, but after exporting, they find that they can't open it, so they will go crazy.

Let’s talk about digital signatures. This function is relatively advanced, but it is also very important. It can verify the integrity and authorship of PDF files and prevent the file from being tampered with. You can understand it as placing an "anti-counterfeiting seal" on your PDF file. When exporting PDFs on PS, you usually need to use other software or plug-ins to implement digital signatures. The specific operation steps will vary from software to software, but the principles are the same. It should be noted that digital signatures require digital certificates, which require application from a professional institution.

Next, let’s talk about some advanced skills. For example, you can control the file size by adjusting the compression level of PDF files. The higher the compression level, the smaller the file, but accordingly, the image quality may drop slightly. This needs to be weighed according to your actual needs. In addition, you can choose to embed fonts, which can ensure that the PDF file can display fonts normally on different systems and software, avoiding garbled codes.

Finally, let’s talk about some common questions and pitfalls. Many friends will encounter problems such as blurry pictures or distortion when exporting PDFs, which is usually caused by improper export settings. It is recommended that you choose high-quality PDF settings when exporting and carefully check the image resolution and color mode. In addition, some PS plug-ins or extension functions may also affect the export effect of PDF, so be careful to use.

In general, the security settings for exporting PDFs by PS are a comprehensive problem, and different solutions need to be selected according to different needs. For general purposes, setting an open password is enough; for scenarios with higher security requirements, permission passwords and digital signatures need to be considered. Remember, it’s no small matter to protect your design works and start with the details! I hope these experiences can help everyone.
