Digital Inks

It refers to the technology of digitally expressing handwriting in a natural form. In a typical digital ink system, a digitizer is placed below or above the LCD screen to create an electromagnetic field that can capture the movement of a special-purpose pen or stylus and record it on the LCD screen.

In addition, sublimation inks can be used for digital printing, so large volumes can be printed at higher speeds. More recently, textile printers have succeeded in printing directly on polyester fabrics with the same sublimation ink.

quality comparison. Where screen printing provides a more vivid finish (especially when printing on dark surfaces), digital distribution is better suited for detail work as it has a thinner layer of ink that allows for a more accurate final print.

Digital printing is best for items that require large amounts of detail and small orders. Unlike traditional printing, there is no pre-printing step between the digital document file and the final product. No need for messy format equipment like film plates or photochemicals.

At the heart of any inkjet printing system is the ink, which is essentially a pigment suspended in a carrier liquid. The role of the ink is to transfer the pigment to the medium and bind it to the surface of the medium. The range of substrates the ink will work with ultimately determines the applications the print engine can handle.

Water is the cheapest and most sustainable carrier, but once the pigment has been delivered to the medium, the water must be dried. Because water tends to seep into uncoated paper, water-based inks can only print on coated paper and the range of suitable substrates is quite wide, but this increases the cost of consumables.
