The unique polymer coating on the PEC allows you to mount your plates directly to the cylinder using the recommended .005 tape. The durable surface of the PEC is resistant to knife cuts and designed for easy mounting, stripping, and remounting of plates.
PEC Surface Preparation and Plate Cleaning
Wipe the surface of the PEC with a mixture of isopropyl alcohol and water, and let dry. PEC’s are resistant to all flexo solvents and inks and will not swell or degrade over time.
The polyester substrate of the photopolymer plate may contain residues from the platemaking process. The plate backing should be cleaned prior to mounting in order to assure good adhesion and avoid plate lift.
Mounting Tape to Cylinder
- Secure the tape to the lead edge first, and with the heal of your hand; apply pressure to the liner with a sweeping motion across the cylinder.
- Slowly turn the cylinder and continue to lay down the tape.
- Apply pressure to the tape to increase the contact and promote adhesion.
- For a uniform butt slice:
- Allow the tape edges to overlap.
- Cut through both layers of tape, angling the blade
away from the tape edge.
- Remove the trim.
The PEC is cut resistant and will not be affected by the score.

Mounting Plate to Tape
- If the tape lifts from the cylinder as a result of repositioning the plate, push the tape back on the cylinder and continue mounting. It is not necessary to remove the tape and begin again due to wrinkles or air pockets in the tape during the mounting procedure.
- Use a rubber roller or your hand and apply pressure to the entire plate surface, particularly the lead and trail edges.
Please note: The sole function of the tape is to provide adhesion of the plate to the surface of the PEC. Air pockets or small wrinkles between the plate to tape, or tape to cylinder, will not affect the performance of the product.
Tape and Plate Removal
Remove the plate from the tape at a 90° angle. A slow removal rate will be most effective and limit damage to the plate.
Use the same technique when removing the tape from the PEC. You may opt to leave the tape on the PEC for future use and recognize additional savings.
Storage
PEC’s should not be stored in direct sunlight or on their side. A peg storage system is recommended, or place cylinders in a vertical position.
