Combines the background, fade and bleed into one continuous sheet at 600 dpi in CMYK; later text, logos and added bugs remain vector. Stops if the whole page would be flattened. Turn off to retain original transparency for Acrobat or your RIP.
Vector keeps artwork as vectors where present and converts text to outlines. Flattened exports render each complete sheet at the selected dpi. Higher dpi cannot restore missing source detail.
Left binding · saddle stitch. Landscape sheets: duplex, flip on short edge. Print at actual size. Test one sheet on your press.
Print checks & processing
Review the detected cut before printing: files without reliable trim information may require manual insets. Mirrored bleed extends the original edges; it cannot invent missing design content. Pages meet at the spine without inner bleed.
Processing stays on this device. The PDF engine loads on first use. Missing fonts, failed processing, and unexpected output sizes stop the download. Maximum input is 80 MB; large sheets may need a lower dpi. This tool does not certify PDF/X or guarantee a particular press color match.
