STORAGE OF RUBBER PRINTING PLATES

• Storage areas should be cool, dry and away from sunlight.
  
  
• Temperature should not exceed 100°F ( 38°C), with 70°F ( 21°C) or less preferred.
  
  
• Store away from sources of ozone, such as motors, welders, corona discharge machines, and other electrical equipment.
  
  
• Plates should be cleaned immediately after use with a cleaning agent appropriate for the type of ink and the type of rubber being used. A soft cloth or soft bristled brush may be used. Excessive brushing or too stiff a brush may damage the plates.
  
  
• Cleaned and dried plates may be dusted with talc or cornstarch for long term storage.
  
  
• Do not stack plates as the weight of plates on top may distort plates at the bottom of the pile.
  
  
• Plates stored mounted on cylinders are more readily attacked by ozone. A black polyethylene wrapper should be used for protection in this case.
