Hello, i have encountered a bug when designing a new pcb:
There are greyish/white stripes all over the image like this:
They are also in the svg version.
This is a known issue, but we haven't seen it for a while. What version of Fritzing are you using and on what platform?
If you are home-etching, you could open up the image in a paint program or SVG editor and remove the lines.
I'm using the version 0.7.12 (b6882 2013-02-13) (Qt 4.8.3) on Arch Linux.
Thanks. As far as I can tell, the lines don't show up when you export to Gerber.
i am having the issue. any solutions for this?
It depends on what you are trying to do. In many cases it doesn't actually affect anything important.
i am trying to make traces for PCB milling from the PNG... so the grey lines creates unwanted horizontal traces in the PCBs. i can remove the grey lines with levels in photoshop / gimp, it's just an extra thing to do, which makes the workflow a bit more cumbersome, so i was searching for a fix.
I've checked and the lines are apparent in the gerber files. Here's a render of a gerber file exported using the latest fritzing on ubuntu 13.04: http://i.imgur.com/ZftitqX.png

I've noticed that the lines don't matter when you send the board to a production service:
I understand this may not be the answer you are looking for if you are etching the pcbs yourself. I thought this might be useful information for those looking to produce the board using a service such as the Fritzing Fab.
This bug has been hard for us to track down. If you email your sketch to info .at. fritzing .dot. org, perhaps we will get lucky and finally track down the problem.
thanks for you reply. i didn't check the "subscribe via email" ticker, so i only see it now.
sending the sketch now.
i am running fritzing 0.6.3 and ubuntu 12.04
any progress on this? having the same issue on mac os x 10.8.5 and fritzing ver. 0.8.3
No progress to report.
Hi again, I'm using the latest version (0.8.5) and this problem still exists.
But there are no grey stripes in the gerber file.
Btw: Reproduction is easy, just create a new project, add a USB-Connector, apply ground fill and you see the lines right there.
i think this is just a "graphical" problem, that's why there is no progress in this issue. the gerber export hasn't the strips, so it's not a problem in the pcb-production from my point of view. has anyone other experiences where the strips are a problem during pcb-manufacturing-process?
if you try to do something like jsr606 does with the export file. i think so far a workaround is to create svg's and fix them in a programm like AI or inkscape.
It may not be a problem with the professional production, but if you're a beginner and doing home-etching it's awful to always load the generated .pdf and painting the stripes black with a really small brush just to see you forgot something and start over again.
