Video Transcript:

After the main exposure process, load the plate carefully face-up into the FAST processor. Make sure the processor is up to temperature and has adequate amount of web to complete the entire plate. Select the plate gauge type and process the plate. After completion, examine the floor as it should be even and relatively smooth. If there appears to be patches of areas where excess polymer exists, the back exposure may be too short and you are not processing down to the real floor. For solvent processing, center the plate in the Cyrel Punch, making sure the plate is level against the back. Punch the plate twice to make sure all the holes get punched all the way through. After the holes have been punched, carefully load the plate face-up into the solvent processor. After you have secured the clamps, make sure the processor is up to the correct temperature and the correct thickness is selected. The optimized washout time is determined during the back exposure step test, discussed in detail in another video. Process the plate and while that operation is going, head to the dryer to make sure it is set at 60oC or 140oF. Once the washout has completed, carefully remove the plate from the solvent processor and place into the dryer. It’s important to note that hotter drying temperatures can cause shrinkage to the polyester support resulting in dimensional stability issues with the plate. Dry for the suggested times based on the plates thickness. The light finishing and post exposure can be performed simultaneously in most exposure units. If you are required to perform these steps individually, be sure to post expose the plate first and then light finish. The proper light finishing is determined with a light finishing step test described in another video. The result should be a plate that is no longer tacky to the touch, and should not be able to stick to itself.
