The ACPU has margins in "inches" and my OS is in "millimeters" the darn thing doesn't even read that correct. How it suppose to work?
Are you serious? You can't figure out how to convert inches into millimeters? ACPU didn't build the target, the application that did can't help you convert units of measurement but it's ACPU's fault? You own Photoshop, try the
Image Size command if you can get past using an Adobe product to aid you with the math. I thought you were serious about needing to print an untagged target. In ACPU or otherwise. Now I suspect this entire genesis of this tread is Anti-Adobe.
Let's try again,
assuming you
really want to print the target in ACPU on Windows. Whatever app built the page, make a target that's smaller than 8.5x11. I recommend 8x10 which can be on an 8.5x11 inch page. FWIW, according to Photoshop's
New Document dialog window>U.S. Page when set to MM equals 215.9mm x 279.4mm. Do you need me to supply a screen capture of this dialog?
