In order to print your sticker white on transparent (even if only some elements of the logo are in white), please provide a fully vectorized file in EPS or AI format. JPEG, PNG, or PSD cannot be used for a white print. You can write a comment or directly name the white parts in your print file.
TIP: you can find all the design requirement for your stickers following this link: https://www.stickeryeti.ch/media/docs/default/EN_Stickeryeti_TechnicalRecommendations_02.02.2022.pdf
