What is it?

Since some of the designs on my silkscreen reference card are a bit unusual, there are occasionally problems with the production. This is a set of 3 boards, which didn't quite pass the quality control.

You will get one each of the white, green and yellow silkscreen cards.

Details

The problem with the green board is, that the inverted silkscreen example in the upper right corner only shows a white area. The text is actually offset and appears below the white square. Additionally all vias for the "text over vias" examples are tented and don't accurately represent the most common situations.

The yellow board also has problems with the inverted silkscreen. In this case the text is offset to the left and partly overlaps the 2mil and 5 mil silkscreen line examples.

For the white board, the silkscreen bleed out a bit. This results in the small text examples being less readable than they should be and the silkscreen lines being wider than they should be.

Please note that the severity of the defect can vary a bit. I tried to select representative examples for the pictures
