I am trying to create an action list in Pitstop to convert a PDF with a scanned image to grayscale. The image mostly contains black text along with a white background. Every action list I've came up with so far has had problems with the white background. It usually converts to something like 94.51% or even 99.61% grayscale (Close, but not exact). I have attempted using several conversion features including "Remap color", "Change color" and "Snap color to a color set". I have also added actions to remove the rendering intent, change the rendering intent to Absolute/Relative/Perceptual/Saturation, remove the ICC profiles, change the ICC profiles, apply transfer functions, and the list goes on.
I'm pretty sure I understand the issue going on: Pitstop is not referencing the white point of the image, so it is not basing the conversion on the white background. Rather, it is referencing some other point, whether it is the black point or somewhere inbetween.
So my question is, can Pitstop do this conversion so that the background is kept at a pure white, or should I be looking at other software to do this?
Thanks for your help!
