Computer integrated manufacturing (CIM) can be defined as the integrated use of computers in manufacturing and other business processes, such as sales, finance, management and distribution. The primary theme of CIM is to deploy systems that can be accessed by employees across the company, from design and development to manufacturing, distribution, billing and post-sale relationship support.
Making a case for CIM
Although CIM has been around for more than 30 years, it has been seriously considered as a method for improvement in the printing industry only recently. Early adopters have discovered benefits such as improved productivity, reduced waste and overruns, and streamlined internal and external communications. These savings prove CIM isn’t just hype—there’s a compelling business case for implementing it.
CIM is not an all-or-nothing proposition. It can be implemented in stages as budget and time allow. But it’s important to identify areas where CIM can benefit your operation today and where it can take your company in the future. Implementing certain aspects of CIM might require some changes in business practices. Automating pressroom instructions, for example, might require more detailed production-planning knowledge from personnel and front office systems.
Implementing CIM in an organization that hasn’t employed these processes and methodologies previously can be challenging. Misconceptions include the following:
Myth 1: CIM for print is impossible.
Reality: Many printers already have implemented CIM. It is easy to find printing companies that have implemented software for:
Myth 4: CIM only addresses the shop floor.
Reality: CIM is a broader concept than just shop-floor productivity. The concepts of CIM represent an enterprise improvement thought process, which will help your entire operation become more efficient and profitable.
Myth 5: Printers won’t change to embrace CIM.
Reality: Successful printers have embraced change from the very beginning, with Gutenberg, and continuing through Linotype, offset lithography, optical and computer typesetting, digital workstations and desktop publishing advances such as the Macintosh, PostScript and PDF. With every new technology, the adoption is quicker. PDF took almost 12 years to become a ubiquitous standard. JDF has been clearly defined only since 2004, and it is taking hold much more quickly.
Myth 6: Printers don’t have the skill sets or motivation to implement CIM.
Reality: In every industry, some companies are adverse to change on the grounds that existing methodologies work "just fine" for their business goals. If you want your company to grow and thrive, however, you certainly don’t lack the motivation to be successful with CIM. Training and a lot of reading will almost certainly be necessary to get everyone up to speed. If leadership is present, and there is buy-in from key managers and operational personnel, printers can be successful with CIM.
Myth 7: You have to replace existing equipment to implement
Reality: Many CIM concepts require little more than a computer with a spreadsheet application. While users can maximize their productivity by using new equipment with JDF-enabled software to achieve the highest level of automation, older equipment can be retrofitted to reap some of these benefits. MAN Roland, for example, has stated that all of the company’s sheetfed presses manufactured after 1995 can be upgraded with its PECOM system, which provides JDF connectivity.
Older equipment also can be "connected" using technologies such as EFI’s Auto-Count system, which provides a direct machine interface (DMI) to the presses, allowing press productivity and waste to be monitored and controlled. Using this technology, managers don’t have to rely on press operators—whose first priority is to run a press—to do paperwork and fill out time sheets when they get a chance. The data integrity provided by DMI makes sure the numbers are right and lets the operators focus on more important qualitative issues, such as achieving color. Although DMI technologies only address one part of the overall shop-floor CIM equation, they can provide a substantial profitablity enhancement. It is not unusual for paper costs to be reduced five to 10 percent almost immediately by implementing this type of technology, resulting in an immediate ROI.
Although some CIM components don’t require additional investments, other parts of the CIM puzzle include tools such as print-management information systems (MIS) and accompanying databases, dynamic scheduling, automated prepress workflows, automatic download of press settings, networked interoperability between machines, and customer-facing systems, such as job submission and soft proofing.
Nonetheless, equipment isn’t always the first place to look for improvement. Although it is compelling to look at big capital expenditures first, there are other ways to improve efficiency, profitability and differentiation. Once you start streamlining your own (and your customers’) activities, solutions will become more apparent.
JDF & CIM: What’s the difference?
JDF is an XML-based specification. It provides a common framework for systems to communicate with one another and describe work processes. JDF enables CIM solutions because it allows different equipment and software programs to share information for more streamlined production. Without examining your current process and taking advantage of process improvements going into a CIM implementation, you won’t be able to reap the benefits of the interoperability and automation JDF will provide.
We’re going to see more applications emerging that employ JDF in ways that help users—in both print buying and printing companies—expand their capabilities to become more efficient and profitable by producing more work faster with the same or less labor.
M&Ms, the Internet and mass customization
By Katherine O’Brien
At first glance, CIM seems incompatible with the printing industry. Print is a custom manufacturing environment—every job is different. CIM is built on rigorous process controls—it involves continous quality and productivity improvement, decreasing waste and extensive data measurement, reporting and analysis. Nonetheless, it is possible to computerize print’s highly customizable process. "Tradtionally, low cost and customization have been mutually exclusive," explains EFI’s Chuck Gehman. "Mass production provided low cost, but at the expense of uniformity. Today, technologies like the Internet allow customers to interact with companies to specify unique requirements which are then manufactured by automated systems."
To underscore this point at EFI’s recent Connect
Users’ Conference, Gehman distributed small bags of
customized M&Ms. A website, www.mms.com, facilitates mass
customization, even for small quantities. Buyers simply click a
button to choose their candies’ color and enter the desired
personalization. Similarly, Web-to-print solutions ensure that
printers are no longer spending $45 of time to enter a $100 job in
their MIS. EFI’s Web-enabled solutions—including
Printchannel, EFI PrinterSite Exchange and PrinterSite
Fulfillment—bring CIM’s benefits to job submission,
production and business management. These tools provide simple
interfaces that allow print customers to log on to branded
print-ordering interfaces, view PDF proofs of their documents for
immediate review and approval and enter job specifications for
production and finishing. E-commerce capabilities let customers
actually buy their jobs online.
EFI PrinterSite Exchange lets printers deploy branded storefront Web sites—Version 2.5 includes new Remote Print Center worfkflow integration, JDF-based job tickets and visual job tickets, variable-data capabilities and enhanced PrintMessenger PDF-generating drivers. Benefits reportedly include streamlined estimating and order input as well as cost savings due to reduced or eliminated prepress labor.
Printchannel—an EFI Web-based ordering solution for variable-data printers—now packs a powerful mailing-list ordering module. Working with USADATA (New York), EFI now provides direct list integration, enabling users to order an entire direct-mail campaign using corporate-approved mailers and lists in minutes.
