Water (H2O) is a polar molecule with excellent solvency. It’s always known as “universal solvent” due to its capability to dissolve a lot of substances compared to any other liquids. There are plentiful sources of water (tap water, underground water, treated water, etc.) which is easily accessible. However, the source of water plays a very crucial […]
The single biggest cost of printing is paper, followed by ink, and then by consumables such as printing plates, blankets, blanket wash, fountain solution, etc. The other important factors affecting the cost of printing are press down time due to make ready, wash ups, press maintenance and also importantly, the skill of the printers. The paper

Do printers have to replace the offset printing blanket due to indentations or low spots? The answer is NO! Printers often encounter problems such as low spots and rubber surface smashes on the blanket during printing. Previously, printers had to stop the printing job half way through and change the printing blanket. This would delay
Surfactants are incorporated in most fountain solutions. These types of surfactants provide a uniform water transfer and enhance the efficiency on wetting the printing plate. Available on the market are a broad range of surfactants. Some of these surfactants have serious negative effects, such as excessive foaming, ink emulsification or even plate blinding. For these reasons, Shadowfax has put a
Isopropyl Alcohol (IPA) has been widely used in printing industry, especially in offset lithography printing. It has some advantages in reducing surface tension of fountain solution and provides better wetting. It also acts as a “coolant” to remove the heat from rollers and the ink rapidly. However, the highly volatile properties of isopropyl alcohol (IPA)

In offset lithography, the dampening rollers transfer the press ready, diluted fountain solution to the printing plate as a way to render the non-image areas of the plate ink-repellent. Isopropyl alcohol, (Isopropanol or IPA) has been, and in some parts of the world still is used, as a popular dampening solution additive because of the
