    Glass-Printing for a Business

    Printing on glass surfaces using printed images is a bit of a trickier task and will require a digital printer. Using this machine opens an array of options. Here are a few things to keep in mind:

    Digital printing on glass, known also as ceramic digital printing allows its users to print absolutely anything they want in high quality. Here are a few helpful pieces of information:

    1. This method allows absolute full control over the format of the printed image.
    2. Manufacturing large quantities of a product is extremely easy using this method.
    3. It is recommended to use primer ink to optimize the end results.
    4. If your goal is to print images that include one to two colors, the best process is screen printing as it is most suitable for such designs.

    If, however, you intend on making colorful objects, digital printing is best.

    The Screen Printing Process

    Screen printing is a practical technique for creating bold canvases and artwork, even on darker backgrounds. This process is also sometimes called serigraphy or silk screen printing on glass. It can be used to print on a number of surfaces, like wood, metal, plastic, and of course-glass. It should be kept in mind that in order to print on glass like a professional, a number of steps should be followed:

    1. A stencil and a mesh screen are used to create a design of choice.
    2. Across said screen, ink is being spread with a swab, squeegee or paint brush.
    3. The stencil blocks and covers certain areas of the glass surface.
    4. All the other areas are left open for the ink to seep through on to the glass.
    5. The ink is then “fired” to adhere to the glass.
    6. This method is ideal for printing commercial materials.

    The end product is a sharp and vivid design.

    The Digital Printing Process

    The digital printing processes appear to be the most popular in recent years and should therefore be researched thoroughly. There are two methods for digital printing: UV-curable printing and digital ceramic printing. Depending on the desired end result, you should decide which process suits your expectations.

    UV-Curable Printing on Glass

    1. To cure the ink on the glass surface, organic inks and ultraviolet light are used.
    2. The printer jets the ink to the glass surface.
    3. No drying is necessary; the glass products are ready to be sold as soon as the printing process is finished.
    4. This process opens up an unlimited array of color options.
    5. Something that has to be kept in mind: the durability of the end product can be questionable and there’s a lack of functional inks.

    Nevertheless, an inkjet printer is an innovative way of printing on glass surfaces.

    Digital Ceramic Printing on Glass

    1. A specially formulated substance named ceramic frit is used. It consists of glass nano-particles, pigmented colors, and a liquid medium.
    2. The aforementioned inks get joined with the glass during printing.
    3. This method is extremely durable and permanent.
    4. All of the possible problems that could arise with other methods aren’t present in this one as the print quality is very high.
    5. The possibilities are truly endless as special effects can be achieved because of the unlimited color options.
