What is Alice®?

Alice is GGI’s new and innovative, digital, direct-to-glass printing technology that allows any design to be printed on glass quickly and cost-effectively.

How long do images last when printed on glass?

Digital images printed directly to glass using GGI’s Alice technology are permanent.

How are images printed on glass?

Alice printing starts with the creation of an image using any current graphics design program. Once the electronic file is created, GGI technicians 1) match colors, 2) scale the image to the correct size, 3) determine the right panel layout, 4) create printing files and then 5) print edge-to-edge creative designs while permanently fusing the image into the glass.

How quickly can orders be filled?

Orders are filled much more quickly than in older, more traditional processes such as silk-screening. Most customers are able to receive final products within two to three weeks of final art/sample approval. Once orders are placed and files are created and approved, the fulfillment process is fast and easy.

Is printing on glass an expensive process?

Printing on glass is extremely affordable and cost-effective for small print runs and customized designs. For example, with Alice, there is no need for multiple screens in order to achieve multiple colors in one image.

Can images be printed on all sizes and types of glass?

Alice can print on most types of glass, including decorative and specialty glass. GGI standard production sizes range from 12”X 12” to 110”X 236” with glass thicknesses ranging from 3/16″ to 3/4″.

How high is the image resolution?

Alice prints on glass at a 720 dpi (dots per inch) resolution.

What are my color choices?

Color choices are virtually limitless with Alice. Our digital color matching process allows GGI technicians to create thousands of shades of colors and an infinite number of opacities.

Can text be printed on glass in any font?

Text, logos, lines, dots, unique designs, illustrations, photos and any other type of image can be printed on glass using Alice.

What is the warranty?

Alice products carry an unprecedented 10-year limited warranty against fading. Customers are protected against image degradation greater than 10 percent over the 10-year warranty period.
