"Purpose","Start with the document’s purpose, then compare a small representative scan at two suitable settings. Higher sampling resolution increases pixels but does not guarantee better recognition or useful detail.","Proposed workflow",""

"Compression","Codec and quality setting","File size and artifacts",""
"Example","A 8.5 × 11 inch page sampled at 300 pixels per inch has about 2550 × 3300 pixels, or 8.415 million samples per channel. At 600, each axis doubles and pixel count quadruples. The final compressed PDF size will not necessarily quadruple because compression and content also matter.","Illustrative; not a measured product result",""
