GS1 Synkka – Primary product image
The primary product image refers to the images intended for the sale and marketing of the product. The product image shows the product in its entirety and nothing else. It is enough to add one good-quality product image to the product, which is:
- always cut out from its background
- tightly cropped, with small spaces at the sides of the product.
You can save several product images in GS1 Synkka. The product can be photographed from different directions and the product can be in packaging or without packaging.
Select one of the primary product images as the main image (Primary file).
Maintain the following information from the code list for the product image:
