Vinyl stickers are primarily used for advertising on vehicles (buses, taxis, trucks), ground-level advertisements, outdoor billboards, directional signs, and flip signs. They have excellent weather resistance and are generally removable. However, due to the lower print accuracy compared to indoor photography, they are less commonly used indoors.

Self-adhesive wall graphics are a type of printed image with a backing that has an adhesive layer, allowing for easy peeling and sticking directly onto walls.

No single black value is allowed in both screen printing and photographic images; C, M, and Y colors must be added to create a mixed black. For a deep black, it can be set to: C=50, M=50, Y=50, K=100. Especially when using it in Photoshop, be sure to change the black parts to four-color black; otherwise, horizontal lines may appear on the black areas, affecting the overall effect.
