Excessive increase of PPI beyond the actual need (e.g., above 300-350 PPI for offset print) leads to unnecessary inflation of file size. This directly increases the RIP (Raster Image Processor) processing time in the Prepress department, raising the system workload and ultimately slowing down the job delivery time.

Therefore, setting the PPI based on actual requirements is considered a strategic decision within the Resolution Chain. This optimization not only maintains sufficient quality but also makes file management efficient and prevents the waste of time and computational resources. It also compels teams to view PPI as a cost-time variable, not merely a quality variable.
