This is seriously interesting and might be quite useful. Thanks for doing and sharing this.

This, Sir, is awesome!

As i'm working in printing industry I found this very interesting. I like that rgb-cmyk conversion formula too :))

What an awesome idea. Converting renders to Ben-Day.

thanks!

This would be ussable for screen printing. Just render each layer sepret to make each screen. Very usful in many ways. Thanks for sharing. :)

this is just AWESOOOOOOOOOOOOME!!!!

Thanks for doing the hard work. This is amazing!

This is great ! what a powerfull tool. There is some mistake though the yellow chanel is not connected properly. -> Green won't work

Hello, BenSimonds! Sorry, but you can have a little bug inside the your Halftone shader (Halftone_Cycles group). Output of "CKYK stage 3" block is have a 3 channel with 2, 3 and 1 lines. But both of this can want to be a 2-linear output. Can i drop you a modified shader template? (Sorry, personal messages is not working)

Hey BenSimonds, I've been getting the same thing rudl has been getting. The green mixing doesn't work in cycles. So I assume this shader has not up to date. This shader would be better as a composite effect, but after tinkering with the compositor nodes myself, it doesn't seem like a feasible thing to do — so good job on what's here. Just fix the green parts and maybe change it to the window texture coordinate to give it that flat look?
