Black and White, no grayscale

[Knight3158]

I am trying to make this image Black and White with no grayscale. Over the last 4 days, I have tried everything I could possibly think of or could learn from online. It seems to be too many colors on too many colors to not have some grayscale. Am I missing something?

One can translate images’ brightness changes into purely black and white pixels with Adjustment Layers and Hard Mix-Pattern Layers. 

What is the purpose of this? Textile printing, stamps, …?

It will be printed out on a banner.

You will probably get the best results when you simplify the image before you make the adjustment to black and white. At least by making the background colors white.

And some elements might benefit from being traced as distinct linework, the thin texts for example possibly with white outlines.

Thank you, Marja, I will try that.

Your image would lose an immense amount of feel if it was either just solid areas black or white with no grey between. There's a solution to that - 

in monochrome printing [like a newspaper] the situation is the same, there is no grey ink, so tones between black and white must be represented by larger or smaller black dots [or it could be lines but that’s a different type of screening]. Have a look at a monochrome newspaper image under magnification, you'll see that tone is represented by larger and smaller dots, all those dots are black.

That's called a "halftone screen" https://en.wikipedia.org/wiki/Halftone

If that result is what you're after then you'll want to convert the image to a halftone screened version.

this video gives an idea how to do that
