There is some slop in the aluminum cover so that eInk screens are not cracked during assembly. This is both vertically and horizontally. Thus each hand built HF32 cart may have a slight variation in the eInk to aluminum cover relationship. It’s understood that this display to cover variation makes it somewhat difficult to exactly center labels.
The templates show two green rectangles. The inner most area is considered the viewable label area. The area between the two bounding green boxes is the bleed area. Artist should fill this area with bleed graphics otherwise sharp borders may be visible after assembly of the HF32 carts. Due to variation in hand assembly of the aluminum covers and eInk displays, artists should not put anything critical in the outer bounded areas, or realistically even close to it. See the included blended images as examples. Ultimately, test your labels on physical HF32 carts to get a full understanding of how they will look color wise and spatially.
The aluminum cover opening is tighter horizontally than some of the FR4 covers that came before it. Thus, order artwork may not fit exactly within these new templates. However, the aluminum covers have been stable for multiple batches of orders now and is not likely to change. Older covers have larger openings such as the early prototypes and some of the red FR4 covers.
