Frosting can give curious guess into the color of the spirit and liquor. It is a quite simple way for glass bottle surface treatment. 
Screen Printing is printing technique where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed. One color is printed at a time, so several screens can be used to produce a multi-colored image or design. 
There are various terms used for what is essentially the same technique. Traditionally, the process was called screen printing or silk screen printing because silk was used in the process. It is also known as serigraph and serigraph printing. Currently, synthetic threads are commonly used in the screen-printing process. The most popular mesh in general use is made of polyester. There are special-use mesh materials of nylon and stainless steel available to the screen-printer. There are also different types of mesh size which will determine the outcome and look of the finished design on the material. A decal consists of the following layers from top to bottom: 1. A paper or film face stock makes up the top layer of the label stock. The printing is done on the upper side of the face stock. 2. An adhesive layer is applied to the bottom of the face stock. 3. A silicone or release coating layer is applied to the upper side of the backing material. 4. A paper or film liner provides the bottom layer of the label stock. When need multiple printing on the surface of glass bottle, decal process is used.
