angier Posted November 20, 2019 Share Posted November 20, 2019 Does anyone know how to prevent or correct the moire effect we get when using the liquify tool? Attached is a close up of one of my graphics. I've approached this problem from every direction I can think of. Any suggestions are welcome. Thanks for the help!

v_kyr Posted November 20, 2019 Share Posted November 20, 2019 You can try to remove a moire effect via noise filters like denoise or dust & scratches, where the later is quite effective.

firstdefence Posted November 20, 2019 Share Posted November 20, 2019 Do you have layers in this artwork that might be working to cause or exacerbate the moire effect?

firstdefence Posted November 20, 2019 Share Posted November 20, 2019 Might also be of benefit to see the whole image. On closer inspection the liquify process has physically distorted the lines and created a "Pseudo" moire effect" for want of a better description, so at points the lines are actually rippled.

John Rostron Posted November 20, 2019 Share Posted November 20, 2019 The go-to tool for removing moire effects is normally the Fast Fourier Transform Filter. Given the unusual source of your effect his may or may not work, but it could be worth a try.

firstdefence Posted November 20, 2019 Share Posted November 20, 2019 Quite a significant difference there. I think Largto's method is the one to go for because of the moire being a physical distortion not a colour shift.

R C-R Posted November 20, 2019 Share Posted November 20, 2019 Does color bit depth have anything to do with this? Like more bits per color creating finer steps or something?

angier Posted November 21, 2019 Author Share Posted November 21, 2019 Thank you to everyone who replied. After I posted for some reason I applied a field blur then I liquified the graphic carefully at 50 - 60% speed, 0 hardness, 40% opacity and the Ramp was on Cosine. Doing this totally helped! It's not perfect but I think I'm on my way to making the liquify tool work the way I need it to. See the attachment. And thanks again for the attention to my request for suggestions.
