Whilst saving out a PDF for print using the default high quality print setting, under - compression - monochrome bitmap image - bicubic downsampling setting, is set at 1200. This produces a large file size and if you reduce this number to 300 the PDF size is much smaller. I can't see any reduced quality and I don't actually have any monochrome bitmap images in my document but I don't actually know what this setting is doing. Could some one explain what it is and if reducing the resolution is going to reduce the quality in some way?
Thanks for the help.
