DPR datamatrix

A DPR datamatrix (otherwise known as Dot Matrix QR) is a QR code which is comprised of dots instead of blocks, see example below

Since dots are being used, this leaves white spaces between the left vertical line and the bottom horizontal line.

To be able to allow the software to properly read this the gaps need to be closed.

Within GlobalVision the current profile needs to be modified using the following settings:

Enable Red Light simulation (found on the right)

To know which options to choose,

Open Filter: Applies to black dots

Closed Filer: Applies to white dots

Options available: 1x or 2x.

Between each dot there are 4 pixels. 1x brings in the dots closer by 1 pixel.

2x brings it closer by 2 pixels, which allows to remove any white space on the left vertical line and the bottom horizontal line.

It merges all the dots together.

This will now allow the barcode inspection to read and grade the QR code accordingly.
