Adjusting the Origin of an Acrobat Document

Does anyone know if there is a way to change the origin (or something along those lines) of a PDF document in Acrobat, so that when I print it to my laser engraver software it registers as the top left corner of the document rather than the center.

For clarity, my current process: Create artwork in illustrator, turn into a fillable form in arcobat, print form fields only from acrobat to my laser engraver software. This is the process follow to make the our nameplates. We have an epilog gavlo fiber laser that uses the epilog software to send the final project to the laser.

When the file comes from acrobat to the laser, rather than the top corner of the pdf aligning with the top corner of our laser bed, the center of the pdf aligns with the top corner of our laser bed.

The origin of coordinate spaces in PDF is the bottom left corner. However, there two boxes that define what bottom left means.

Here's an article that explains this in terms of the JavaScript model:

https://www.pdfscripting.com/public/PDF-Page-Coordinates.cfm

Under the covers it's slightly different because JS always makes the crop box 0,0 at the bottom left corner. But in reality the origin could be different.

Do you know how the laser engraver converts the internal coordinates of the PDF?

Do you know what the current media and crop boxes are for the problem PDF?

I am not aware software wise how the laser converts coordinates, but when the pdf is brought in the pdf Media Box is centered about where we choose to set the origin of the laser. We could adjust the origin on the laser but since some tags are different sizes this won't work unless we change it each time.

As far as the boxes, I'm not sure which of them if any would be the issue. It could be something thats just not possible between the Epilog and Acrobat softwares.

Hi @Marcus39052773p8y2,

I don't have access to the printer, though. You may want to check the "Print Production" tool. Launch Acrobat and open the PDF Form you use. Choose All Tools> Use the "Print Product" tool. You may want to check these options:

Set Page Boxes: Allows you to define the crop, trim, bleed, art, and media boxes on a page. The elements are important for proper page positioning and placement of printer marks, especially for imposition.

Add Printer Marks: Adds standard printer marks to a PDF page for positioning. These marks are embedded in the PDF.
