Flexo/Litho Printing Solvent Recovery

Flexo/Litho Printing Solvent Recovery

Kresco is a pioneer in the fabrication of solvent distillation and recycling systems for the printing industry. Our systems are widely used by major flexographic and lithographic printers around the world in order to reclaim and recycle cleaning solvents used for maintaining their printing equipment. The end product is a pure solvent blend that has equivalent properties to those of the original product.

Printing Machines Cleanup

Maintaining printing machines, and cleaning up printing cylinders, printing plates, inkwells and other mechanical components exposed to printing inks require significant amount of cleaning solvents.

In the latest flexographic and lithographic technologies, a very small quantity of solvent is sprayed on a cleaning fabric which is rubbed against the printing rollers and blankets in order to obtain a more efficient cleaning process, somehow faster, and requiring less solvent.

Unfortunately, it is not the case for printing presses of older generation. As a matter of fact, integrated sprinklers combined with oscillating brushes systems require a much bigger volume of solvent. And, as opposed to cleaning fabrics which can be disposed of in regular waste stream, waste solvent blend generated from older presses cleanup are hazard materials and must be disposed of properly in accordance with local jurisdictions.

A large blue barrel filled with dark liquid sits under a long metal pipe, which is releasing liquid into the barrel—a typical scene in solvent recovery processes for litho and flexo printing. Several hoses and cables run along the industrial floor next to metal equipment.

In some printers serving a large number of customers, color changes are frequent due to some customers who require a specific PMS color for their projects, which requires a printing rollers and blankets cleanup in-between each job. The volume of waste solvents generated for cleaning up printing equipment can sometimes be substantial and lead to significantly high hazardous waste material disposal costs. Not to mention that those printers must hire specialized contractors to collect and dispose of their waste properly. This practice is costly, involves the storage of a great deal of clean/used solvent drums in the shop and requires to fill out time-consuming EPA reports.

Fortunately, Kresco has a far more beneficial solution to offer, safe for user, environmentally-friendly, and very simple to use. Kresco provides a complete range of solvent recyclers designed to separate pure solvents from inks and other substances through an on-site distillation system. Reclaimed solvents can be reused over and over for presses cleanup. Our solvent distillers are safe to use, have a very small footprint in the shop and allow for significant savings, making your business more competitive and green.

Kresco’s Line of Solvent Distillers

Kresco’s line of Solvent Recyclers allows you to reclaim and recover your waste solvent through a controlled and fully-automated solvent distillation process. With our systems, you will be able to separate pure solvent from 3D printing resins and other contaminants with optimal efficiency, safety, and consistent quality. Depending on the components included in the substance, you should expect recovery rates yielding from 95% to 99.9% of the original product.
