Flexographic printing: Where does tape come in?
Flexographic printing has come a long way in a short time. Improved technology has made the process faster and more precise. The many uses of flexography include offering a speedy way to apply designs and label information to various packaging materials. A flexible plate creates the design by using a raised image. Manufacturers can select from many colors, and the method is economical.
So, what role does tape play in flexographic printing?
Tape's uses in flexography
Double-sided adhesive tape is the best solution for flexography. The tape balances two critical performance aspects. It has the right balance of tack while also allowing for clean removal.
What does that mean for the user? The tack level is essential to keeping the plate in place. A sturdy tape prevents the plate from moving during the printing process. When you finish the job and it's time to demount, the tape has to come off easily. You don't want to leave any residue on the cylinder or plate after the job. Taking time to clean the plate of tape residue adds time and hassle to a project and makes it last longer than you want.
You should be able to rip the tape off without leaving anything behind. At the same time, the tape must withstand pressure well to get the job done.
Plate mounting tape eliminates plate edge lifting and bubbling. It should bond to the plate or cylinder securely, leaving no room for lumps or bumps. A tight fit ensures a clean printing job, cushioning the plate from vibrations. The tape provides the support you need between the press and the plates.
Proper ink transfer
Using the wrong tape will result in a subpar printing job. The tape that secures the plate to the printing surface must display the right thickness and softness. Otherwise, printing defects can occur, su
