watermark on every fixed number of pages

[RK20]

I would like to insert a watermark on my pdf document every fixed number of pages (ex. every 5th page).  However, there is currently only the option to select a range of pages or every odd or even page.  

Having this feature would be very useful to me as my resources are 200-300 pages, the watermarks are distracting, and for security purposes not necessary to have on every page.  I'm hoping this feature can be developed soon.

Thanks.

 This can be achieved using a custom-made script.

Do you want to use an image, or text? Where should it appear, and what should it look like?

Thanks. I want it to appear on the top of the page, text and I've attached a sample of what I would like it to look like. The water mark is on the top left corner.

Try this code:

var watermarkText = "Purchased by A Smith January 7, 2022";
for (var p=0; p<this.numPages; p++) {
	if (p==0 || p%5==4)
		this.addWatermarkFromText({nStart: p, cText: watermarkText, cFont: "Arial", nFontSize: 8, nHorizAlign: app.constants.align.left, nVertAlign: app.constants.align.top, nHorizValue: 14, nVertValue: -24});
}

You can run it as a part of an Action or from the JS Console.

I'm not familiar with this. Would it be possible for ut ot meet briefly via zoom so you can show me how.

I usually charge for private consultation sessions. If you're interested you can contact me via [try6767 at gmail.com].

You can learn here how to use the JS Console:

FYI for others that encounter this, try67 via email explained to insert the code "you just need to press Ctrl+J, paste the code into the window, select it all and then press Ctrl+Enter." And this worked and the code worked.
