I am trying to create seamless pattern repeats. Most of the time when I do this I get thin lines between the tiles (I place the original pattern and move>copy it to exact measurements). I have read in other forums that these are 'ghost' lines which don't appear when the design is printed out, but I've had fabric samples printed that do contain a line. Also sometimes the motifs on the edge of each tile don't match up - see the slight line down the orange / white cups here:
I move>copy the motifs using the exact measurements of the artboard, I line up my clipping mask with the artboard and they are exactly the same size, and they have no stroke width. I can't work out why it still does not work.
Even before I copy and tile the design I sometimes have a thin white line down one side - see below. I would really really appreciate help!
Something strange seems to be going on.
The alignment seems to be off in both directions, so that the pattern to the right is too far to the right and down; and the bottom of especially the orange cup is further disaligned, as if the pattern to the right is stretched vertically.
What version of Illustrator are you working in? If it is CS 6 then you are going about it wrong as you do not need to clip it to make the pattern.
The lines you speak of arenot the same lines as you aregetting as Jaob points out youshow a definite mismatch of the art which is what is causing your lines.
I know, this's quite old stuff, but maybe someone'll find it usefull.
Try eps instead ai. I've got the same problem with patterns imported to InD - white thin lines in pdf visible after rasterizing in PS. When i imported eps, not ai, tile lines have gone.
