Hello.
Having recently updated to Creative Cloud, I've notice that the pdf stitch lines scenario has changed somewhat.
I am aware that, for many years now, when exporting a pdf (Acrobat 4 PDF 1.3) any transparency layers within the artwork result in very thin white lines being visible on the file.
I had sent thousands of artwork out to press in that way, and was confident that the lines would not print.
One of the ways I would put clients minds at ease though would be to rasterize the file into Photoshop, save as a jpg and hey~presto, said lines are all gone.
Now, (since CC update) if I rasterise a pdf, the lines do show! They're there in the channels, ok albeit very faintly, but they are there.
If I flatten, and save as a jpg, they're visible.
Has anyone else noticed this since the CC update? I'm still new to it, so I'm sure some of you have.
Just hoping someone can put my mind at ease, and say they're ok and still will not print.
Below is the cyan channel, rasetrized in Photoshop
