What is the role of a press check?

• A. To verify color, ink density, and impression quality on press during production and approve or adjust as needed.
• B. To adjust the color profile of software.
• C. To select paper stock.
• D. To set the machine speed.

Answer: (A)

A press check centers on verifying color accuracy, ink density, and how the image prints on the press while production is underway. The goal is to compare live print samples to the approved proof, checking color balance, tonal range, density, and registration. If any aspect doesn’t align with the proof, adjustments are made on the spot—tweaking ink balances, pressure, paper handling, or other press settings—to ensure the final run matches expectations and minimizes waste. This real-time verification and adjustment during printing is what makes a press check essential.

Other tasks described in the other options happen earlier in the workflow or are separate steps: adjusting color profiles in software is a prepress activity, selecting paper stock is decided before printing, and setting machine speed is part of the makeready/press setup but not the primary focus of a press check.
