hair like lines show in my prints after flattening

these are small hair like lines and show rectangle shaped boxes, they print in the finished images, is it my merging process? I rasterize my smart objects and text first then merge down the other layers one at a time and it occurs, I let PS do it all and it occurs, the lines look to be the size of the bounding boxes that would show while adjusting the various items in my composite, running the latest update on CC.

Thanks for any advice

You might also want to try changing the blend mode on the layers to lighten, that might cancel out the dark lines.

I've seen this when using layer masks where the composited element is smaller than the image it is added to. I just tried to duplicate the effect, but was not able to, but I can't remember the exact circumstances. Did you have layer masks before you flattened?

yes, I do have layer mask and the images are 5616x3744 300dpi going into a 9000x6000 300dpi back drop

Before you flatten, Alt click each layer's Eye icon which turns all the other layers off. If a layer reveals a rectangular hairline, select the layer and roughly draw around the object in the layer with the lasso tool, but inside the hairline. Then invert the selection, and delete.

If you get out of sync and find lots of layers turned off and can't turn them back on, select those layers, and turn on with Ctrl , (Ctrl comma)

I can't think of an easier fix other than doing it layer by layer.

I guess what you could do is add a layer above the background layer and fill it with a colour like green. This would make the hairlines show up very clearly.

Then group the other layers, and add a layer mask to the group, and paint out the line using that mask. This won't work where lines overlap required objects. You'd have to go back to fixing those layer by layer.

Few questions...

1, where are you printing this? or is someone else printing and are you sure its not the printer?
2, Do you know if you actually have layers that line up to those lines? if you do, then it's simply because you don't have enough overlap between the layers to make sure it's filled in.
3, don't merge down and flatten. you lose any way of editing after the fact. Stamp the image instead. When you are highlighted on the top layer, it's Shift+Option+Command+E. It creates a new layer combining everything below the highlighted layer. This might also help keep the final clean instead of weird lines like that.
4, are you printing right out of photoshop? if so, are you zooming in and actually checking for this stuff on the image file before printing?

I was doing full sized test runs at sams club, never had this happen before tonight, yes the layers can be toggled on-off and the matching lines go away, running nec 272 monitors and I do zoom in, they are set to proper pixel count so an inch is an inch of screen space

Can you show some screen shots?

this is 66% zoom sizing on a 20x30 composite poster image

this is a basketball team composite made up of 25 masked images, all full resolution from 5dmkiii, this arm is a showcase for my problem, large .psb files while building the document out, could that be my problem?

And this bnb is flattened? If it isn't, this often happens with images that aren't viewed at 100%. Do you have overlap with the images? Did a layer style somehow get attached to the layers?
