Ziska

Unfortunately, the back of the card has an extra 0.25 inch margin on all sides. There is also 0.5 inch between the barcode and the edge of the paper in both the PDF and the printed version.

Additionally, the Ziska logo, publisher logo, retailer logo, disclaimer, publisher SKU, and Ziska SKU are not centered over each other. It appears the internal white space within each element is affecting their alignment.

Here are two suggestions, though feel free to implement what works best:

Adjust the disclaimer to span the full printable width with a 0.25 inch margin. Center the text within that container box and use as little white space as possible, since excess spacing will affect alignment.
Create a full-width element container box. Center the text and all variables within it, using minimal white space to avoid adding extra spacing that could throw off alignment.
