Decal Applications The use of decals offers a full spectrum of colors while providing both a pricing and design alternative to either etching or direct screen-printing. This process is typically used for large runs of 1.5 to 6 liter bottles. Water- slide decals are hand applied to empty bottles, cured for 24 hrs, and fired at upwards of 1,200° F to permanently fuse them onto the glass. The practical aspect of decals is similar to direct screen-printing in that they cannot be torn, scuffed, wrinkled or soaked off the bottle surface. The cost is competitive to both paper and pressure sensitive labels. Click on image to see label details.
