Q: What is an ink?
A: An ink is really just a special type of colored glue. Its purpose is to record an image on a support such as paper or vinyl. The support is also referred to as the "substrate."
The three main components of an ink are the pigment or colored material, the binder or glue, and the solvent mixture. The solvent mixture allows the ink to be printed on the substrate, then it evaporates. This creates a strong bond between the substrate and binder, which holds the pigment in place to form an image.
Q: What is True Solvent Based Ink,Eco-Solvent ink,Water Based ink,UV Curable ink?
A: True Solvent Based Ink
When True Solvent Based Inks were launched, they became immediately popular largely for their durability, low cost, and ability to adhere to uncoated substrates. The inks are largely used to produce billboards, fleet graphics and outdoor signage and banners due to their durability. They need a ventilated area to protect workers against volatile organic compounds (VOCs).
Eco-Solvent ink
A major benefit for EcoSolvent ink is the extended printhead life and limited need for ventilation systems or HAZMAT shipping. These environmentally friendly inks are able to print high-resolution, outdoor- durable billboards.
Water Based ink
Water Based Inks offer an advantage with their smudge-resistant formula when used with the proper-coated media. Whereas the dye-based ink is suitable for indoor graphics, the pigment-based variety is more fade resistant and has high light fastness even when exposed to sunlight. Although the receptor-coated substrates generally cost more, these environmentally friendly inks provide excellent value.
UV Curable ink
UV Curable Inks are ejected in liquid form though the printhead nozzle, and dry instantly when exposed to UV light. These inks are suitable for flatbed printers and the benefits are in the wide range of substrates available and longevity on outdoor media. Special attention to the process is essential as the light source has to be fine-tuned and the ink requires special handling.
From solvent-based to UV curable inks, SolTeck produces every types of digital inks for use with all large and grand format ink jet printers, both in bulk and in cartridges. SolTeck knows very well that every printer, printhead and substrate needs a specially formulated ink to match, so whatever composition you demand, SolTeck has the complete color range that you need. Whether printing in low or high resolution, on PVC, self-adhesive vinyl, paper or textile, SolTeck ensures consistently superior results every time.
Q: What is a piezo inkjet printer,a thermal inkjet printer?
A: Piezo inkjet printer
A piezo inkjet printer uses one of two major types of printheads: drop-on demand or continuous flow.
Drop-on-demand systems are those in which an electrically stimulated crystal changes shape, creating pressure on the ink chamber and forcing ink through the nozzles. Drop-on-demand printheads are made in Japan by Epson,Konica and Seiko, in England by XAAR and U.S.A by Spectra and are incorporated in wide-format inkjet printers. Continuous-flow inkjets use an electrical charge to deflect a continuous flow of ink. Different types of continuous-flow piezo inkjet systems are used.
One of the benefits of piezo inkjet printheads in that they can be engineered for use with either water-based inks or inks in which the colorants are suspended in a solvent such as oil, naphtha-alcohol, acetone, or other solvent.
Thermal inkjet printer
As the name implies, thermal inkjet printers use heat as part of the process. In a thermal inkjet, the inks are repeatedly heated to create bubbles, which force the drops from the nozzles. Unlike piezo inkjets, which can be engineered for use with a wider variety of inks, all thermal-inkjet printers drop-on-demand systems that use water-based inks.
