Luminance-Based Monochrome Color Transformation

PDFCore Studio transforms RGB color data into monochrome luminance using standard ITU-R BT.601 colorimetry weights: Y = 0.299R + 0.587G + 0.114B. This ensures text and graphics retain high contrast without becoming washed out when printed on laser or monochrome office printers.
