Outdoor Use
Preventing ink fading
  Be sure to use light-resistant durable inks designed for YUPO® according to the required level. Laminate with a PP film or a PET film as required.
Attaching posters
  When attaching posters, we recommend using double-sided tape or YUPO® that are self-adhesive treated. YUPO® sheets may tear when thumbtacks are used, so be sure to use double-sided tape in conjunction to the thumbtacks.
Posters in harsh conditions
  In cases posters, banners, or signs are to be used in rugged conditions such as wind and rain, a lamination of film should be applied to avoid problems such as ink fading or running. For such applications, always be sure to check in advance your selection of inks, laminating methods, and adhesives.

  • When laminating, be sure to use water-resistant, strongly adhesive inks.
  • Some pre-coat type laminating films lack water-resistance and adhesion.
Applying posters to mirrored surfaces (metal, glass, coated surfaces, etc)
  When applying posters to metal, glass, or coated surfaces, water that gets between the YUPO® sheet and the contacting surface can evaporate quickly in high temperatures. As a result, the YUPO® sheet will become welded to the contacting surface and coatings may be peeled off when the poster is removed. This is not just a case with YUPO® and can happen with any film-based product. However, for example, when using double-sided tape, it is necessary to ensure that there is no water between the YUPO® sheet and the contacting surface.
