Hello everyone!
I regularly scan drawings, then color them digitally after using Preview (I’m on Mac) to select the areas to “punch out” so I can fill them uniformly with color.
However, this process is sometimes lengthy, and I discovered when using another scanner (Canon Pixma MG29505) that the monitor allowed me to save images in black and white in PNG, and then the surface of the image is completely uniform, and no longer “grainy,” which allows me to color the surfaces with one click, without having to punch them out beforehand.
This is a huge time saver, so I tried to see if it was possible to reproduce this on my scanner and its monitor (MP Navigator EX 2.0), but I don’t think that's the case. And when I convert the JPG file obtained from this scanner to PNG afterward, I don’t get the same smooth result as when I scan directly in PNG with the Canon Pixma.
Do you know if it is possible to modify the settings on my MP Navigator EX 2.0 scanner, or if it's possible to achieve the same “smooth” file type that’s easy to color from a JPG scan?
I will probably post a similar message about quicker coloring formats in the “graphic design” thread, I hope this won’t create a duplicate.
Thank you very much for your attention!

I solved my problem thanks to a friend, I'm posting the solution here in case it can help someone!
It was indeed impossible to directly obtain the "smooth" format I was talking about with my scanner, which turns out to be the Bitmap format.
But you can get it with Photoshop by going to:
-Image => Mode => Change from "RGB" to "Grayscale"
-A window appears asking if you want to discard the color information => Yes
- Return to Image => Mode => select "Bitmap"
- In the dialogue window, choose the 50% threshold mode
And there you go! By saving the file as PNG or TIFF, you get a black and white drawing where the black is really black, the white is really white, and the areas can easily be colored in one click, as they are standardized.
