Description:

This is a node group that you can use for converting RGB image textures into CMYK halftones. It comes with two different versions, one for cycles, one for blender internal. For more on what it is and how it works, see this post on my website.

    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.

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

    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?
