The role of stickybackin flexographic printing

The stickyback is a key component within the flexographic printing process, although its main objective is to maintain and ensure the adhesion of the plates to the cylinder of the machine, its role within of the process is decisive to guarantee the fluidity and quality of the result.

• Plate adhesion: Used to adhere the plates to the printing cylinder.

Registration Accuracy: Ensures that printing plates are held in the correct position on the cylinder, maintaining color accuracy and alignment.

• Stability during printing: Provides solid, reliable adhesion that prevents plates from sliding or shifting.

• Facilitates the printing process: By keeping plates firmly adhered to the cylinder, double-sided tape contributes to a smoother and more consistent process, reducing the possibility of problems and adjustments during production.

• Plate changes: Facilitates quick plate changes when different designs or jobs need to be printed. The plates can be removed from the cylinder relatively easily and replaced with others without problems.

• Regarding its own characteristics: The thickness and hardness directly influence the final printing result; they must be selected based on the type of printing that will be executed. Printers use their hardness depending on the finish they want to obtain. Thus we have that: The semi-hard is used for white backgrounds and thick texts, because they have more coverage, the semi-soft for CMYK prints, plots and fine texts, because the dots come out with low gain (better defined) and the hard is recommended for whites and backgrounds.

As you can see, it occupies a leading role in the flexographic printing process. To prolong its useful life, it is important that you follow the manufacturer’s recommendations and keep detailed records. This way you can make timely decisions about when to replace it, maintaining high production in your printing press. efficient and smooth.
