Hi,

Can I add trim inside the pdf content.

Yes, enable crop marks first with this CSS:

@page {
    marks: crop
}

Sorry, I accidentally deleted your post! Can you post again?

But the crop marks are unable to bring inside the pdf content, I want to bring the crop marks inside the pdf content, Also tried negative value of bleed and trim,

Crop marks inside the printable page area? I'm afraid Prince does not have support for that, you will need to add them as images yourself inside the page regions, perhaps like this:

@page {
    @top-left-corner { content: url("top-left.png") }
    @top-right-corner { content: url("top-right.png") }
}

May I ask why you need to crop marks inside the printable page area?

The issue is that we need to add the "trim box" inside the pdf. A pdf of 5 inches by 8 inches - We want the trim box at 4.75 inches by 7.75 inches.

How do we draw that? Please note we do not want crop marks but want the trim box inside so the printers can use the trim box for cutting.

Can you please help with this?

You can set a prince-bleed value without using cropmarks. It sounds like you just need to set that to .125in to achieve what you’re looking for. e.g.:

@page {
    size: 4.75in 7.75in;
    prince-bleed: .125in;
}

That'd generate a 5x8 PDF with a trim box within it that measures 4.75x7.75, and no crop marks at all.
