Will PDF exporting on PS be distorted?

To export PDF without distortion, you need to follow the following steps: check the image resolution (more than 300dpi for printing); set the export format to CMYK (printing) or RGB (web page); select the appropriate compression rate, and the image resolution is consistent with the setting resolution; use professional software to export PDF; avoid using blur, feathering and other effects. For different scenarios, high resolution, CMYK mode, and low compression are used for printing; low resolution, RGB mode, and appropriate compression are used for web pages; lossless compression is used for archives.

PS export PDF, distortion? This question is awesome! Many friends have a headache about this. In fact, PS exporting PDF distortion is not the "pot" of PS itself, but the result of the combined effect of the export settings and the characteristics of the file itself. Let’s analyze step by step to see how to avoid this annoying situation.

1. Image resolution is the key

Many friends click to export directly, and the result is a tragedy. The root cause lies in the resolution of the image. Imagine that a low-resolution picture will naturally blur after being enlarged. After exporting it to PDF, this blur still exists, and is even more obvious. So, be sure to check the resolution of the image before exporting. Generally speaking, print-grade works require at least 300dpi, and web pages can be used lower, but clarity must be ensured. If your image resolution is too low, even if the export settings are perfect, it cannot be compensated. At this time, you have to consider re-acquisition of images or use AI image enhancement tools to improve resolution. Although the effect is not necessarily perfect, it is better than being muddy into a ball.

2. The knowledge of exporting settings

There are many mysteries hidden in the export settings of PS. Many people use the default settings directly, and the result is... you know. Focus on several parameters:

• Color mode: If it is for printing purposes, it is recommended to use CMYK color mode, which can restore the printing effect more accurately. If it is for web page purposes, RGB is enough. Never use it in conjunction, otherwise the color will be severely deviated.
• Compression settings: The compression settings of PDF will affect file size and image quality. The higher the compression level, the smaller the file, but the image quality will also decrease. It is necessary to weigh the trade-offs according to the actual situation. It is recommended to test the effect with a low compression ratio first, and then adjust it as needed. JPEG compression is a common choice, but be careful that excessive compression leads to loss of details.
• Resolution: The resolution set here is different from the resolution of the image itself. It refers to the resolution of the image in a PDF document. Generally speaking, keep it consistent with the image resolution. If your image resolution is high, but it is set very low here, that can also cause distortion.

III. The impact of file format

Some friends will use PS to process vector images and then export PDFs. The vector diagram itself will not be distorted, but during the processing process in PS, if blur, feathering and other effects are used, some information may be lost, resulting in slight distortion after exporting the PDF. In this case, it is recommended to process it in AI or other vector graphics software and then export the PDF directly.

4. Common misunderstandings and pitfalls

• Misconception 1: I think there will be distortion when exporting PDFs on PS. This is wrong, as long as it is set properly, distortion can be avoided.
• Point 1: Ignore image resolution. This is the most common cause of distortion.
• Point 2: Use inappropriate color mode. Will cause color deviation.
• Pit point three: Overcompressing the image. This will result in loss of image details.

5. Optimization suggestions for different scenarios

• Printing Purpose: Be sure to use high resolution images (300dpi or above), CMYK color mode, low compression ratio, and carefully check all settings.
• Web page purpose: Lower resolution images (72-150dpi), RGB color mode, can be used, and appropriately compressed to reduce file size.
• Archive purpose: Lossless compression is recommended to preserve the original image quality.

In short, the problem of PDF distortion exported by PS is not unsolvable. As long as you master the correct skills and methods, you can easily avoid it. Practice more and summarize more, and you will also become a master of PS exporting PDFs!
