Almost weekly I have been asked to supply CLEAR Stickers or Decals. The first question I have is How will the stickers or decals be used? What is the color of the item they will be applied to? Generally the color to which they are mounted to has to be a light neutral color, preferably white.
Colors need to be backed up with white or the printed graphics and text colors will bleed out and take on the background colors. Basically with any sign, vehicle graphics or even a banner, has to isolate and/or support the colors intended. All efforts of color matching and color management will be a waste of time and effort on clear medias or substrates.
If you look closely at clear decals or stickers, there will be generally a halo of white around the images printed text. Even though it appears to be clear, additional costs of materials and equipment have been incurred, to apply a detailed layout of white ink first.
So remember, a clear background on a sticker, decal, vehicle graphic or other signage, does not necessarily relate to lower cost. a contour or detailed die cut on a white media may offer the best unit costing long-term.
