When contemplating the intricacies of preparing a PDF for printing, one might ponder whether flattening the document is an essential step in this process. What are the ramifications of maintaining layers versus merging them into a singular, cohesive image? Does the act of flattening a PDF enhance its visual fidelity or perhaps streamline the printing workflow? Furthermore, could it mitigate potential printing discrepancies related to font rendering and graphical inconsistencies? In a world where precision is paramount, particularly for professional presentations or high-quality reproductions, how does one assess the necessity of this action? Are there particular scenarios, such as when dealing with intricate designs or relying on specific printer capabilities, where flattening becomes not merely beneficial but crucial? Additionally, how might the final outcome differ based on the original complexity of the document? Is it possible that flattening could inadvertently strip away essential elements needed for certain applications, thereby complicating matters further?
