Artwork Job Template allows you to set up crop function and add mask for cropping.
- Crop dimensions are set in pixels. In below image, I set the print size from product - 90 x 180 mm and convereted it into pixels - ~1067 x ~2128. Imaged didn't cropped.
- After I set Crop to 800x800, final artwork cropped. Notice that Crop is set from top-left corner and then center of artwork shifts.

- Mask is set according to Crop dimensions. In this case, mask file with circle in middle has the same dimensions as artwork.

- As previously mentioned, mask will fit into crop dimensions and can get deformed. In this case, same circle mask was uploaded but height dimension stretched almost 2x.
