Prepress, also known as pre-production, is the crucial stage in the printing process that occurs between the creation of artwork and the final printing. It involves a series of steps designed to prepare digital files for commercial printing. The primary goal of prepress is to ensure that the final printed product accurately reflects the designer's intentions and is free from errors.

Key activities in prepress include checking and correcting files for any technical issues such as low-resolution images, incorrect color modes, or missing fonts. Color management is a critical aspect, where colors are converted to the appropriate color space (typically CMYK for printing) and calibrated to ensure consistency. Proofing is another vital step, where a physical or digital proof is generated for client approval to catch any last-minute errors before the main print run.

Prepress also involves imposition, which is the arrangement of pages on the printing press in a specific sequence so that when the printed sheets are folded and bound, the pages appear in the correct order. Trapping is sometimes applied to prevent gaps or misalignments between adjacent colors. The final output from the prepress stage is typically a print-ready file, such as a PDF, that is sent to the printing press. Effective prepress is essential for achieving high-quality printed materials and avoiding costly mistakes during production.
