Clear Window Clings are made of 8mil thick clear glossy material with a paper backer that will be peeled off prior to application. They are suitable for indoor or outdoor use. Ideal for POP signage on glass or other very smooth, clean surfaces. Excessive heat or cold will not allow the product to cling to the surface.

With Clear Window Clings, you have the option to use white ink as an overprint so your printed graphic can be opaque in some areas and transparent in others. This will allow for vibrant, crisp color.

Similar to Spot UV masks, White Mask files are separate from your artwork files and black color indicates where the white ink will print.

Make sure to create your mask file the same size as your color art file. This will prevent alignment issues during printing.

Note: White Masks must be made in vector format and be saved as EPS or PDF and use 100% K.

Use vector paths/shapes to create black color areas that will indicate where the white ink base will go. The rest of the area will represent the Clear Window Cling stock.

Black in the White Mask file indicates where white ink will be printed. Remember the following when creating a white mask for your white ink base:

- White ink base will be printed behind any color that’s in your Artwork Layer.
- Areas with color but without a White Mask will be printed with color directly on the material. These areas will have somewhat transparent color due to the Clear substrate.
- Areas with color and a White Mask will be printed as opaque or solid color.
- Areas with a White Mask and no color will be printed as white.
- The black for the White Mask file must be 0% C 0% M 0% Y 100% K or it will not be recognized by preflight.

If your Clear Window Cling is intended to be viewed from the outside of a window, please select "Mounted From Inside" when building the product. Also, the artwork should be reversed prior to submission. See images below.

As long as the cling remains clean it can be reused several times. We recommend that you keep the backing to protect the cling if you plan to reuse it.

Start with by thoroughly cleaning and drying the window or application surface. Use a spray bottle filled with soapy water to spray to completely cover the application area. We recommend 1% soap and 99% water. Carefully peel away the backing and avoid letting the cling fold over on itself. Place the side that had the backing against the surface and apply the cling to the window. Use a squeegee or credit card to squeeze out access water pressing from the center outwards. You can spray more soapy water on the back of the graphic to lubricate the surface as you are eliminating air bubbles.
