Digital printing is a method of printing from a digital-based image directly to sheet, rollstock, or films. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. The savings in labor and the ever-increasing capability of digital printing methods means that Spartech digital printing technology can match or supersede conventional printing methods' ability to produce high-quality print runs at competitive prices.
Water Transfer Printing
Water transfer printing, also known as immersion printing, water transfer imaging, hydro dipping, watermarbling, cubic printing, Hydrographics, or HydroGraphics, is a method of applying printed designs to three-dimensional surfaces. The water transfer printing process is extensively used to decorate items that range from entire all-terrain vehicles and car dashboards, to small items like bike helmets or other automotive trim. Films can be applied to all types of plastic substrates. For the most part, if the item can be dipped in water and can be painted using traditional techniques then the hydrographic printing process can be used.
In the process, the substrate piece to be printed first goes through the a preparation process. A PVA hydrographic film, which has been printed on with a desired graphic image using latex or pigment-based inks, is carefully placed on the water's surface in a dipping tank. Once dipping starts, the surface tension of the water causes the pattern to curve around any shape. Any remaining residue is then rinsed off thoroughly. The ink adheres to the surface and is then allowed to dry. The adhesion is a result of the chemical components of the activator softening the base coat layer and allowing the ink to form a bond with it.
Sustainability. The Key To Future Value.
