Setting Tips for PECíS
The key advantage of a PEC is to provide a platform
for a plate that will
allow for over impression, and absorb vibration that
is created in the nip.
The vibration that is created is a combination of
shafts turning, gears
meshing, plates contacting anilox rolls, variation
in cylinder TIR, and the
shuddering created by the die cut station along the
frame of the press.
The coating responds as a shock absorber and allows
you to over-impress
the plate to the substrate with out the usual negative
the anilox roll to the plate, making equal adjustments
the plate is inked, adjust the plate to the substrate
adjustments to both sides to insure parallelism,
the printing plates inks the substrate, make small
impression until you are confident that the impression
cylinder, and anilox roll are parallel to each other,
off the anilox roll impression until it just starts
some press configurations, you may have to advance
the plate cylinder
to the impression roll to avoid excess anilox to
this point, you may start to apply impression to the
until you achieve the desired results
Former training may cause hesitation in applying impression
to the plate cylinder. The product is designed to
absorb the extra impression so do not be reluctant
to squeeze the plate to the substrate.
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.
Preparation and Plate Cleaning
Wipe the surface of the PEC with a mixture of isopropyl
alcohol and water,
and let dry. PECís 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 plate making process. The plate backing should
be cleaned prior to
mounting in order to assure good adhesion and avoid
The recommended tape is available from Nu Tech Coatings.
It is perforated,
and has excellent adhesion which allows for:
Easy application to the cylinder.
Removal of the liner.
Virtually assures that any trapped air will be allowed
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
Apply pressure to the tape to increase the contact
and promote adhesion.
For a uniform butt slice:
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.
a rubber roller or your hand and apply pressure
to the entire plate
surface, particularly the lead and trail edges.
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.
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
PECís should not be stored in direct sunlight or on
their side. A peg storage system is recommended, or
place cylinders in a vertical position.
