e. Make sure that vacuum blanket is clean and that vacuum exhaust holes remain uncovered.
NOTE
• If additional flats are to be exposed on the same plate, or if the plate is to be used for multiple color printing,
register marks should be inserted in the flats, or some sort of register system should be used to register the job.
Register marks are placed so they expose the plate outside the image area, so they can be trimmed off after the
job is printed.
• The sensitivity guide is designed to overcome the problem of incorrect exposure. The guide is stripped into the
edge of the flat in a nonprinting area, usually the outer edge.
