Glass Printing Machine has been used since the mid-1990s for the purpose of reproducing digital format images on the hard surface. Most commonly, this is used for mass print production of photos, art and other large format artwork. Ceramic printers are used in this process. Digital printing on glass can be done in two different ways, digital inkjet printing and laser printing.
Description Digital printing on glass is an innovative technological advance used for the commercial application of digital image, pattern or text on the surface of hard flat glass. As with other digital printing methods, it makes use of a special form of image reproduction. In digital ceramic inks, tiny droplets of color are propelled on the surface through a continuous flow of water. The droplets of color are then spread over the surface in uniformly spaced bubbles which become the image.
Uses Digital printing on glass has various commercial applications. Ceramic inkjet printing can be utilized for printing high-resolution logos, business cards, flyers, signs, banners and much more. It can also be used to print text, data and graphics on flat surfaces including metals like stainless steel, copper, aluminum and glass. For digital printing on glass, ceramic inks are mixed with metallic dyes which provide for the colors to pop out.
Image Processing Digital printing with inks entails a process of transferring an image using an inkjet or laser beam onto the flat surface that is to be printed. Depending on the application, the method may include photo processing software to apply the image processing software or manual drawing procedures. The image processing software can be computer based such as Adobe Photoshop and its standard image processing software like Paint Shop Pro.
Optical Character Recognition Digital printing on fabric with inks involves recognition of characters in the form of patterns and symbols from electronic images. This is done through the use of specialized cameras and digital printing equipment wherein the characters are printed onto the glass surface. These characters are then converted into alphanumeric characters by means of the image processing software. This provides for the production of barcodes, price tags and holograms which are useful for industries like the retail, entertainment and shipping industries.
Thermal Transfer Ceramic print out from digital glass printers involves the transfer of an image from the print head to a coated glass surface. In this technique, the inks have a thin film of a particular material deposited on the glass. The heat of the printer is applied onto the deposit which forms a sort of a layer on the glass. When this layer dries, a clear sheet of glass is formed. This type of technique is commonly used to create door hangers and promotional material branding.
Silk Screen Digital printing using inks on glass is also known as silk-screen printing. It is often used in the production of large-scale advertisements where the visibility of the print is extremely important. It makes use of tiny particles of silk and other materials like nylon to create images. To make silk screen printing more effective, an image conversion process is employed wherein a computer model is generated beforehand and the printouts are done on the glass by using special equipment.
All the three techniques are applicable for digital printing on glass. These techniques have their own advantages and limitations. A highly recommended way of minimizing the environmental impact of any printing job is to utilize raw materials that have the highest water or energy content. These can include recycled paper or recycled plastic. Additionally, the use of printers with a green conscience would go a long way in making printing processes more eco-friendly. For those who wish to print large volumes of posters, labels or other promotional materials, it would be advisable to hire professional print shops to do the job for them.
