Blanket wash cleans the blanket in offset sheet-fed pricing. There are a number of scenarios where it may be necessary to clean the blanket, and Mid-State Litho supplies several different blanket washes to meet our customers' needs. All washes have the capability of cutting ink, which will cause it to mix with the wash itself. This makes the mixture to become more viscous in order to be wiped away.
Blanket wash and solvents can contain harmful chemicals and release VOCs (volatile organic compounds) as they evaporate. In the recent past, there has been a hard push to green this process of printing and come up with more environmentally friendly forms of blanket washes.
Blanket Washes come in a wide variety of formulations for specific applications. Certain types of blankets perform better with specific formulas of blanket wash. Some other blanket washes are engineered to work specifically with a particular type of blanket material. There are even blanket washes that are formulated to be water-miscible meaning that they can be mixed with water.
Environmentally Friendly Washes
In modern times, we are all aware of how important it is to take care of our natural environment and our bodies. Both government regulations and a widespread drive from end users and operators have led manufacturers to come out with specialty Blanket Washes that have extremely low levels of VOCs and low oder without compromising performance in the press room. Although these blanket washes are certainly better to use, they do come with an added expense of operation. For this reason, environmentally friendly blanket washes have not yet been universally adopted in operation throughout the entire printing industry. With time and perhaps some further regulation, the industry will no doubt fully transition to better more responsible formulas.
