This article is aimed at office scenarios such as contracts, bids, scanned documents, and archived materials, explaining how to use HeSoft Doc Batch Tool to add a perforation seal to PDFs in batches. The article first shows multiple PDF files and unsealed pages before processing, then demonstrates the effect of a perforation seal appearing on the right side of the page after processing, and illustrates the complete workflow through the software interface, from selecting "Add Stamp to PDF", importing multiple PDFs, setting all pages, choosing the perforation type, uploading the seal image, to adjusting position and scaling, helping users efficiently complete multi-file sealing work.
In daily office work, contract PDFs, bid proposal PDFs, acceptance documents, policy files, and scanned archives often need to be stamped with a cross-page seal. The issue is that these types of files are usually not processed individually but in batches. For instance, a project folder might contain multiple PDFs, each with several pages. Opening and stamping each file manually is not only inefficient but also prone to missing stamps, positional deviations, and version confusion due to fatigue.
This article will focus on the high-frequency need of "batch applying cross-page seals to contracts and bid proposal PDFs," introducing how to use the office software " HeSoft Doc Batch Tool " for batch processing. This software is positioned as a batch document processing tool, suitable for centralizing repetitive file operations, such as batch processing PDFs, Word documents, Excel sheets, and images. This article highlights the setup method for cross-page seals within the PDF add stamp feature, allowing you to follow the steps directly after reading.
Applicable Scenarios: Why Contracts, Bid Proposals, and Archived PDFs Need Batch Cross-Page Stamping
The function of a cross-page seal is typically to certify that multiple-page materials belong to the same document, reducing the risk of page substitution. In paper documents, the seal spans the edges of multiple pages; in electronic PDFs, a similar effect can be achieved by placing a stamp image along the page edges. Batch adding cross-page seals is particularly valuable for the following scenarios:
- Contract Documents: Procurement contracts, sales contracts, service agreements, supplementary agreements, etc., often require a uniform cross-page seal on every file.
- Bidding Materials: Bid proposals with numerous pages and attachments are very time-consuming to process manually page by page; batch stamping can improve delivery efficiency.
- Internal Company Policies: Policy PDFs, notice PDFs, appointment documents, etc., need uniform stamping before distribution or archiving.
- Scanned Archival Materials: After paper documents are scanned into PDFs, if electronic cross-page seals need to be added, this can be done through the PDF stamp function.
- Batch Project Documents: Multiple PDFs under the same project, such as 1.pdf, 2.pdf, 3.pdf, 4.pdf, need the same seal added at once.
If you are searching for "how to batch stamp contract PDFs," "add cross-page seals to bid proposal PDFs," or "how to uniformly add stamps to multiple PDFs," the workflow in this article is very suitable for reference.
Effect Preview: What Changes After Batch Adding Cross-Page Seals
Before Processing: Multiple PDF Files Waiting for Stamping
In the pre-processing folder, you can see multiple PDF files; the example includes 1.pdf, 2.pdf, 3.pdf, 4.pdf. These are all objects to be batch-processed this time. Using traditional methods would require opening and setting up stamps for each file individually, which is highly unsuitable for cases with a large number of files.
After opening one of the PDFs, you can see that there is no stamp on the right edge of the page. In the screenshot, the red arrow points to the right margin area of the page, which is precisely where the cross-page seal will be added later. For multi-page PDFs, cross-page seals are usually placed at the page edge, which reflects continuity while minimizing interference with reading the main text.
After Processing: Cross-Page Seals Appear on the Right Edge of the PDF
After batch processing is complete, open the PDF again, and you can see parts of a purple stamp appearing on the right edge of the page. Parts of the stamp edge are visible on different pages, forming a cross-page seal effect. It will not be completely pressed onto the center of the page like a regular stamp but will display along the page edge, better aligning with the usage habits for contract and bid proposal type documents.
Comparing before and after processing shows that after batch adding cross-page seals, the page edges of the PDF files have a uniform identifier. For files that need archiving, review, or submission, this uniform processing can reduce subsequent inspection workloads.
Operation Steps: Batch Add Cross-Page Seals to Contract and Bid Proposal PDFs
The following steps are explained in conjunction with the software interface. Note that the software name in the screenshots is " HeSoft Doc Batch Tool ". This time we are using the "PDF Add Stamp" function under the "PDF Tools" category on the left, not the watermark function or PDF conversion function.
Step One: Open PDF Tools and Enter "PDF Add Stamp"
After launching HeSoft Doc Batch Tool , select "PDF Tools" from the tool category on the left. The main interface will display multiple PDF batch processing function cards, such as PDF Add Watermark, PDF Delete Pages, PDF to Word, PDF to JPG Images, etc.
To add cross-page seals, you should select "PDF Add Stamp." In the screenshot, this function card is shown as "7. PDF Add Stamp," with the description text being "Batch add stamps to PDF." This aligns with the need for batch stamping PDFs like contracts and bid proposals.
The key for this step is selecting the right function. Watermarks and stamps are visually similar, but cross-page seals belong to the stamp processing logic. The subsequent interface will show two stamp types: "Normal" and "Cross-page," so you should enter through "PDF Add Stamp."
Step Two: Import PDF Files to be Batch Processed
After entering the function page, the top displays the current function as "PDF Add Stamp." The process is divided into 4 steps: Select records to be processed, Set processing options, Set save location, Start processing. First, stay on step 1, where you need to add contract PDFs, bid proposal PDFs, or other PDFs waiting for stamping to the list.
There are "Add Files" and "Import Files from Folder" buttons in the upper right corner of the interface. If files are scattered in different locations, you can use "Add Files"; if files are concentrated in the same directory, using "Import Files from Folder" is more suitable for batch processing. The screenshot shows that 4 PDFs have been added, with paths D:\test\1.pdf, D:\test\2.pdf, D:\test\3.pdf, D:\test\4.pdf.
In the table, you can check the file name, path, extension, creation time, and modification time. The bottom shows the record count is 4, meaning these 4 PDFs will all enter the subsequent batch stamping process. After confirming the files are correct, click "Next" at the bottom.
Step Three: Set the Processing Range, Decide Which Pages to Stamp
After arriving at Step 2, "Set Processing Options," you first see the "Processing Range." The selectable options include "All Pages," "First Few Pages," "Last Few Pages," "Odd Pages," "Even Pages," and "Custom."
For cross-page seals on contracts and bid proposals, selecting "All Pages" is usually recommended. The screenshot currently shows "All Pages" is selected, which means every imported PDF will participate in the stamp process across all its pages. If your business rules only require stamping certain pages, you can also use other range options.
The processing range setting directly affects the result. If only some pages are selected, cross-page seals will not appear on other pages. Therefore, before formal batch processing, confirm the requirements of your unit or project regarding the number of pages to be stamped.
Step Four: Select "Cross-Page" as the Stamp Type
On the same settings page, you can see the "Stamp Type" area with two options: "Normal" and "Cross-page." The Normal stamp is suitable for placing a complete seal at a fixed position on the page, such as stamping the lower right corner of the first page; Cross-page is suitable for distributing the stamp along the page edges, used for continuous identification of multi-page documents.
This time we need to batch add cross-page seals, so "Cross-page" must be selected. The red box in the screenshot marks the "Cross-page" option, indicating the current setting is correct. This option is one of the most important settings in the entire process, determining whether the final effect is normal stamping or cross-page stamping.
Setup Purpose: To have the software process the stamp in a cross-page manner, rather than simply placing the full seal on each page.
Expected Result: Parts of the stamp appear on the page edges of the processed PDF, forming a sense of continuity across multiple pages.
Step Five: Upload the Stamp Image
In the "Stamp Image" area, click "Choose File" to import the seal image. The screenshot shows "1 file selected," indicating the stamp material has been added successfully. The image selected here will serve as the unified stamp source for all PDFs.
It is recommended to check the quality of the stamp image before importing. The cross-page seal image used for PDFs should be as clear as possible, and the color should not be too light; if the image background is transparent, it usually looks more natural when overlaid onto the PDF. If there is a lot of white space around the seal, it might affect the display ratio of the cross-page seal at the edge; this can be adjusted later with the "Crop Edge White Space" and scaling settings.
Setup Purpose: Specify the seal material for batch stamping.
Expected Result: All imported PDFs will use the same stamp image, ensuring a uniform stamping style for contract or bid proposal documents.
Step Six: Choose Fixed Position to Make the Cross-Page Seal Appear on the Page Edge
In the "Position" area, you can choose "Fixed Position" or "Custom Position." The screenshot shows "Fixed Position" is selected, and the middle area on the right side is chosen in the diagram. For most contract and bid proposal PDFs, the right edge is a common position for cross-page seals, as it is less likely to obscure the main text and conforms to reading and binding habits.
If your PDF page layout is special, for example, the main text is close to the right edge, or you need to place the cross-page seal on the left edge, you can adjust the position based on the actual effect. It is recommended to test with one file first to see if the stamp covers the text, page numbers, or important tables.
Setup Purpose: Determine where the cross-page seal will appear on the PDF page.
Expected Result: The stamp is located at the page edge, and the processed result shows a partial seal body on the right side, similar to the effect diagram.
Step Seven: Adjust Rotation, Cropping, Transparency, and Scaling Effects
The "Effects" area on the right displays multiple adjustable items, including "Rotation Angle (Clockwise)," "Crop Edge White Space," "Opacity Level," and "Shrink or Enlarge." The screenshot shows "Shrink or Enlarge" is turned on and provides a slider that can be adjusted among "Shrink," "No Change," and "Enlarge."
These settings are mainly used to optimize the stamp display effect. For instance, if the stamp is too large, you can shrink it appropriately; if there is too much white space around the stamp image, consider cropping the edge white space; if the stamp obscures the main text, adjust the opacity level. Since different PDFs have various page sizes, it is recommended to check a proof before large-scale batch processing.
Setup Purpose: To make the size, clarity, and coverage of the cross-page seal more aligned with office document requirements.
Expected Result: The stamp is clearly visible, uniformly positioned, and does not significantly obscure the main text information.
Step Eight: Set Save Location and Start Batch Processing
After completing the processing options, click "Next." From the top workflow, you can see that "Set Save Location" and "Start Processing" follow. The save location determines where the processed PDFs will be output. It is recommended to create a new output folder, such as "Contract PDFs - Cross-Page Sealed" or "Bid Proposal PDFs - Processed," so they can be kept separate from the original files.
After setting the save location, proceed to "Start Processing." The software will execute the add cross-page seal operation on multiple PDFs in sequence, based on the imported file list and stamp settings. After processing is complete, open the output files for spot-checking to confirm that the expected stamp appears on the page edges of each PDF.
Setup Purpose: Protect original files and batch generate PDFs with cross-page seals.
Expected Result: A batch of new PDF files is obtained in the output directory, suitable for subsequent archiving, sending, printing, or submission.
Frequently Asked Questions and Notes
1. Do I need to back up original files before batch stamping?
It is recommended to keep the original PDFs. Although batch processing is efficient, if the position, size, or stamp image is selected incorrectly, reprocessing might be needed. Saving output files to a new directory is a safer office habit.
2. Are the same settings suitable for both contract and bid proposal PDFs?
Not necessarily. Contract PDF pages are usually quite regular, while bid proposal PDFs may contain various pages like covers, tables of contents, tables, and scanned copies. It is recommended to test by file type first before deciding whether to use the same set of position and scaling settings uniformly.
3. Why is only part of the stamp showing?
Cross-page seals are typically designed to appear at the page edge, so what you see on a single page may only be a part of the stamp. As long as a continuous effect is formed across multiple pages and it meets your stamping requirements, this is normal behavior.
4. Will different page orientations affect the result?
Possibly. The edge positions differ between landscape and portrait pages, and the display effect of the stamp might also vary. If a batch of PDFs contains both landscape table pages and portrait text pages, it's recommended to spot-check different page types first.
5. Is it possible to process only odd or even pages?
From the interface, "Odd Pages" and "Even Pages" options are provided in the processing range. If business rules require adding stamps only to certain types of pages, you can use these range settings. However, conventional cross-page seals are usually more suitable for all pages.
Conclusion: Improve Contract and Bid Proposal Processing Efficiency with Batch PDF Stamping
To batch add cross-page seals to contract and bid proposal PDFs, the focus lies in three steps: first, import all PDFs to be processed into the list; then select the "Cross-page" stamp type and upload the stamp image; finally, set the position, size, and output directory. HeSoft Doc Batch Tool integrates these repetitive operations into a batch workflow through the "PDF Add Stamp" function, effectively reducing the time spent on manual file-by-file processing.
If you frequently need to process multiple PDF files, whether they are contracts, bid proposals, scanned copies, or archival materials, you can first test the cross-page seal effect with a small number of samples, and execute the batch process after confirming it is correct. This not only improves office efficiency but also ensures consistent stamping results for the entire batch of PDFs.
