When placing an image on a product, it would be nice if its appearance remained consistent across different forms of the product. In particular, when placing an image on one shape or style of a product, if it still looked good on all the other ones. After all, no Zazzler wants customers to select a certain form of a product, only to be met with a less-than-good appearance of an image or, worse, empty space. Yet placing images for consistency of appearance can be a bit of a challenge. Not only can Makers offer new forms or styles of existing products, ones which have different design dimensions, but sometimes, just getting an image to look good on all the existing options can be problematic.
Designing for Zazzle thus requires some careful thought on how to go about placing images, at least if they are intended to fill all the design area of a product. (Note that the design area includes the safe area, guaranteed to remain on the finished product; a border which may or may not get cropped during printing; and a bleed area which is supposed to get cut, except not assuredly.) Obviously the shape of an image plays a big role, as does the precise placement, with centered, square images seemingly being the safest to work with. Aspect ratio and precise placement aside though, in my experience, it is usually just a matter of fully expanding the image on all the different forms of a product in turn, and then checking on all the others to see how things look. Appearance can then be optimized for all current forms, at least, simply by working on the “right” one to begin with.
