1. Resolution or quality setting: When exporting a PDF, if you choose a lower resolution or lower the image quality, the color and clarity of the watermark may be affected, resulting in shallowness. It is suggested to choose a higher resolution and image quality to ensure that the quality of the watermark is not affected.
2. Background color setting: The brightness and contrast of the watermark are related to the background color. If the background color of the contract is lighter or similar to that of the watermark, the watermark may merge with the background, resulting in lighter color. Before exporting the PDF, check the background color of the contract and ensure sufficient contrast with the watermark color.
3. Printer and printing settings: If the contract is printed by a printer, the color and quality of the watermark may be affected by the printer settings. Adjust the printer settings reasonably to ensure that the color and clarity of the watermark are consistent with expectations.

In addition to the above reasons, there are other factors that may cause the watermark to become shallow. For example, there may be something wrong with the software tools used, or the design and transparency setting of the watermark itself are inappropriate. When solving the problem, we can try to use different software tools or modify the design parameters of the watermark to get better results.
In addition, for the important information in the contract, it is suggested to take other security measures besides watermarking, such as digital signature and encryption, to ensure the integrity and confidentiality of the document. At the same time, it is helpful to check the effect of watermark and the printing quality of contract regularly, and keep the software and printing equipment updated and maintained, which will help to avoid problems such as shallow watermark.
