Homebrew PCBs

Opening the picture and zooming in on the 3 mil one, the line width and
spacing are not consistent.  I do not think that is caused by the Windows
viewer.  The result is the same using Photoshop.  In other words, be careful
and verify the dimensions before using the picture.

 

Here is a link to more resolution tests, both a standard resolution chart
and a printer/PCB chart that includes angular tracks besides
horizontal/vertical ones.

Do not use a web PDF viewer to check it out since the resolution is poor.
Even an official viewer start to fail at the 1 mil track level.

For best accuracy use the CAD version or the Gerber version since they are
accurate vector drawings.

Mark,

 This is test image .tif to test 3 mil through 12 mil line/spacing.  Can you
take a picture of it when you print it?
