Since 1996, COP Communications has been organized into 3 divisions, California Offset Printers, Inc. , ICI Digital, and ICI-Publishing (Post Magazine and Computer Graphics World).

Currently, we produce, print or publish over 120 regularly scheduled publications that maintain their long term relationship with us. We are very proud of our past. In 1984, we were the proud printer of all the Official Olympic Event Guides, produced and delivered daily to venues in the Southern California area. This set a standard for gold medal service to our customers which we still provide today. Under the ownership and leadership of William R. Rittwage, President/CEO, we have emerged as the premier regional producer and printer of magazines, catalogs, event guides, directories and other publication services.

We also have helped printing publications grow circulation with our Digital Magazine Production (while complying with BPA and ABC requirements) and help cut programming costs by using our custom Website CMS tool.

“Our Goal Is Your Success”. Our company philosophy focuses on providing solutions, customer satisfaction and quality assurance. The common goal is to provide technology-driven services to customers in a cost efficient manner. We intend to remain as current and qualified as the industry demands. Our proven print production expertise will be there when you need it as a catalyst to your success.
