Flexographic printing
Compared to gravure printing, flexographic printing strengthens its position in the market thanks to rapidly increasing print quality, operability and lower costs. Sleeves technology has brought an increase in the pace, simplification and reduction of costs in the subject of replacement of the printing form and in the time of proper printing. When using sleeves, laminate sleeves are provided with an elastomer or polymer layer on which a printed pattern is engraved. The finished sleeves are put on the air cores of the flexographic printing machine.

Ink rollers
WerographHigh-quality ink rollers with a long service life and good chemical resistance. The rollers ensure good paint transfer and problem-free cleaning.
Werograph-HX (NEW!)
Much more resistant to chemical reactions, prevents the so-called rubber corrosion and ensures ink roller stability in sheetfed offset printing with conventional inks - especially on high-speed presses up to 18,000 sheets per hour.
Wero-UV + LED UV 2.0 (NEW!)
Coatings for ink and waterjet rolls, optimized exclusively for printing with UV inks.
Weromix
The special quality for ink and dampening form rollers for mixed printing. This quality is also recommended for hybride inks.
Weronews
A new generation of rollers optimized for printing with inks based on vegetable oils (so-called vegetative inks).
Weronit
Rider or distributor rollers as an alternative to ril-san coated rollers. This quality offers an excellent runability and is also used for the recovering of film rollers with rhomb or polygone profile.
Dampening rollers
WeroaquaA new generation of wetting rollers designed to reduce IPA and for alcohol-free printing, enable stable printing both with the classic dosing of IPA, with its reduced quantity and without IPA.
Werodamp
Consistent hardness and a special hydrophilic surface ensure optimal dosing of the wetting solution in sheet and roll printing
Werodahl
High quality combined with mechanical resistance, the coating used in the Dahlgren and Delta water systems for water feed rolls. Excellent media resistance.
Werodamp-LT
New generation water ducts designed to reduce IPA and for alcohol-free printing. Very long service life. Easy cleaning with reduced consumption of detergents. Extremely high media resistance. Reduction of paint backflow. Short maintenance time.
Other rollers
Others:- varnishing rollers

The new formula of the UV 2.0 mixture for UV printing developed by Westland-Ligum is a response to changes in the composition of UV inks as well as new applications for Low Energy, H-UV and LED-UV printing appearing on the market. The selection of the appropriate mixture is preceded by detailed information received from the customer, it is also conditioned by factors related to its use as well as dictated by the working environment of the ordered product.
Reduce costs and enjoy a stable printing process, high wear resistance of the rollers and a longer service life.
The UV 2.0 mixture is characterized by exceptionally high chemical and mechanical resistance, which translates into a reduction in the effort incurred for maintenance activities and, consequently, extending the life of the roller. Other properties that characterize this mixture include the reduction of typical phenomena occurring in the UV printing process, such as swelling or shrinkage of the rubber and the change of its viscosity. It is worth noting that LED UV 2.0 is now standard with the largest OEM UV machine manufacturers and is becoming more and more popular in Europe and in the world.
