Tape to Plate First - Reversing the Liner:
If you prefer to mount the tape to the plate, the liner must be reversed on 3M™ Cushion-Mount and Cushion-Mount Plus Tapes.

Step 1: Peel back liner leaving tape on roll. Step 2: Unwind liner back to starting point. Step 3: Position plate and trim to size. Step 4: Remove the liner and mount it on the cylinder.

Use the excess liner that was trimmed off to rewrap the roll and cover the exposed adhesive.

Lower Adhesion:
If lower adhesion to the plate is necessary, a coating may be used on the back of the plate to facilitate clean removal. A 50:50 mixture of wood shellac and alcohol or a 50:50 mixture of ink extender (polyamide) and alcohol are common coatings that help reduce adhesion. Leave an uncoated border around the edges of the plate. This will minimize plate lifting. This technique may be needed when working with thin or low durometer photopolymer plates or with ground rubber plates where the grinding operation increases adhesion.

Note: When using coatings, be sure to follow manufacturer's directions and precautions for handling such materials.

Increase Adhesion:
A solvent based marker or adhesive primer such as 3M Primer 94 or Fastbond 30 Contact Adhesive can be used on plate edges or on sleeves to promote adhesion where lifting is occurring.

Note: 3M Fastbond 30 Contact Adhesive is not "solvent-based".

Bevel Plate Edges:
Plate edges can be bevel-cut to minimize plate lifting. Storage of mounted cylinder or sleeve should be in a controlled environment. Excess heat and humidity can significantly increase adhesion levels. A solvent-based marker or adhesive primer can be used on plate edges or on sleeves to promote adhesion where lifting is occurring.

Cylinder/Sleeve Storage:
Storage of mounted cylinders or sleeves should be in a controlled environment. Excess heat and humidity can significantly increase adhesion levels.
