Easier to see zoomed out, but there is a clear line where the halftone seems different. This is in the same couple approximately 1/2" thick lines going down the screens the long way. Always in the same couple channels on the screens.
A few halftone jobs we have had to go back to using film instead of the CTS because of this. It's very noticeable in the print on large halftones of the same opacities..
We replaced the CR encoder strip thinking that would fix the issue but it didn't (this is the help we were given, and other than that would need to pay $2k + for a tech to fix it...).
Here is an example of it which is very obvious:
I've never seen it anything like that bad on a real screen though.
Anyone have experience with this type of banding issue on an Epson? What needs to be done to fix it?
