If you are talking about more than just printing but actually want the digitial instance to be absent of color why I do not know there are several ways however the simplest is just to print to PDF and change the print from default and or color to black and white. Keep in mind though if many soft tones are used they might in black and white or gray scale be indistinguishable eg pastel light hues will all be a kind of greyish white so pastel yellow in a light tone and pastel blue in a light tone would be very similar in grayscale. The easiest generic non-application specific based method is simply to print to PDF in black and white. For Adobe Acrobat which is what most use for PDF files as it has industry dominance If you want a veryplex method Distill to a PDF then in Acrobat go to tools Print Productionconvert colors Device gray Convert Profile grey gamma 2.2 don't profile. Use advanced output preview to toggle the black separation on and off to confirm the file is black only. Adobe Community. However I would save yourself the headache and just print to PDF and change the print setting to black and white this works universally and just creates a new instance which is going to happen anyway and of course if you are going to change the version like that you are going to want to save it as a different version. No matter how advance the technology bes nor how small nor how multifunctional keep in mind aputer is basically two things a huge file cabinet and a calculator. When ever you are talking about datastructure which in its simplest most basic sense is just organizing things into smaller and smaller files in a huge file cabinet you want to ask your self if you were doing it physically what would you do for example if forgetting for a moment all aboutputers you drew a picture in color and I was like this is great but I need it in black and white can you redraw and you did would you then burn the color copy because some one wanted it in black and white.
