Start with an original image
ACE automatically prepares the uploaded JPG for the configured product size. This matching is part of your product setup; you do not repeat it for each order. The documented variant naming example is:
Poster_21x30_tryckfilsnamn
Use lowercase letters for the artwork name and do not use underscores inside that artwork name. The separators in the full variant example remain underscores.
