I have a pdf template file with printers marks and a bar code. I'd like to add graphics to the file (essentially cover the whole page). Covering the printer's marks is required, but I'd like the bar code to survive the coverup.
How can I accomplish this?
Here's the template. PDF's can't be uploaded here, so it's a screen shot. The printer only issues templates in pdf or InDesign format--there are no other options. Notice the bar code in the left panel:
The blue portion must be covered completely, like so:
Notice that the bar code now is different, because it's not the bar code that came supplied with the template. I'd like to preserve this bar code in some way.
In terms of tools, I've created the overlay using various programs, Photoshop, Affinity Photo, Gimp, etc. But I'm having trouble preserving the bar code.
If I just open the template in Photoshop, for example, and copy the barcode, I can't paste it into the overlay because the barcode is only 72 dpi when you do a cut and paste in this fashion, and the template must be at 300 dpi. If you resize the image after the cut and paste, it's fuzzy. Is there a way to do this with layers, where the only element on the template, the bar code, is preserved onto the overlay, which would be on a new layer?
