All About Offset Printing And Chemicals Used

Alcohol-free “wet” offset technologies are important not only in the interest of photo printers but for a stronger, more profitable business. The optimization of automatic offset printing program for the eco-friendly dampening components via free alcohol and purification procedures is a further milestone of the traditional offset technology ecological approach.

Offset printing, also named “wet” offset, uses dampening solution to be able to keep non-printing elements as a hydrophilic on top of offset printing plate. So fountain option would be a portion of its procedure. Generally, it is composed of water and around of 8-10% isopropyl alcohol as an area active agent improved wetting. However, there are natural issues with this technique, such as adverse ecological impact, health hazardous, complex media functions and waste water and substance regulations. Isopropyl alcohol used in water solution in offset printing has adverse influence as portion of it vaporizes to type substance toxins that contaminate the workplace, also toxic and combustible. Calculated by volume IPA is the most significant air pollutant in the Offset Printing Supplies. In the common environment savings conditions, there are different methods to reduce or even completely IPA-free printing, lowering costs and risks for safe practice the surroundings.

In web offset, printing is several possibilities to apply alcohol 100 % free dampening solution. In this study for the CSWO (Cold Set Web Offset) printing it was applied completely alcohol 100 % free solution with specially developed preservative, compatible to personal regular water properties. In addition here was used ceramic narrow to avoid fast pollution and also permit longer durations between changing the fountain solution and keeps it clean for a long time. So in this way, we achieved having constant printing procedure without any problems.

Best Wash Up Blades are manufactured to fine specifications for an ideal fit on old and new presses alike. They are resistant to substance attack from ink and chemicals and are highly efficient and durable.

An ideal profile ensures excellent wash-up results each time, lowering the amount of wash-up chemicals used and decreasing downtime on the media.

Blades are available for a large proportion of offset sheet-fed, the web and ongoing type presses in either metal/rubber, metal/urethane, rubberized (EPDM), plastic or Tufnol format. Every blade is presented in a plastic sleeve with the machine reference for easy identification.
