Upload the `alphaprepress-pdf-preflight` folder to `/wp-content/plugins/`, or install the ZIP via Plugins Add New Upload. 2. Activate the plugin through the _Plugins_ menu in WordPress. 3. Go to **PDF Preflight Settings** to configure your preflight rules. 4.

No. All analysis is performed on your own server using PHP. ### How accurate is the image resolution check? Resolution is estimated from the image pixel dimensions relative to the page size. It is a strong indicator but, for pixel-perfect placement analysis, use a professional prepress RIP. ### Can I generate a real downloadable PDF report? Yes. The report exports as a self-printing HTML page (browser “Save as PDF”). If you install a PDF engine such as Dompdf and hook the `pdf_preflight_render_pdf` filter, a true PDF binary is produced. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “AlphaPrepress PDF Preflight” is open source software.
