PRODUCT APPLICATIONS:
Long-run offset printing on web
and sheet-fed presses.
EXPOSURE GUIDE:
Use a high intensity UV light source. The exposure time
will vary according to the distance and wattage of the
light bulb. Using an IBF 21 Plate Scale, expose lhe
plate to a solid step 3.
Using a 2,000 watt light bulb at 31''/80cm from the
plate, expose for 40 seconds. Insufficient exposure
can create lack of details.
PROCESSING:
MANUAL PROCESSING:
Pour and spread IBF Negative Developer
with a sponge over the plate and let the developer dwell
there for 10 seconds.
Remove the coating, pressing the sponge in a circular
motion.
Do not prolong the development unnecessarily. When the
nonimage area is free of coating, it will be sufficient
to pass the sponge once again with the developer to
ensure that the plate is totally developed.
AUTOMATIC PROCESSING:
IBF Negative Plates can
be easily processed using a continuous dry-to-dry option
on the various automatic processor models available.
