When it comes to duplex production, the numbers tell an interesting
story. A large proportion of the jobs produced in commercial and in-
plant operations involve duplex applications.
Océ user research indicates that in produc-
tion environments, some 80 percent of
traditional publishing jobs printed on high-
volume cut sheet devices are printed on both
sides of the page.
These jobs include books, booklets, manuals, reports, letters, course
packs, and catalogs. All are duplex applications that have traditionally
been printed on simplex devices, by passing each page through the
device twice to print on both sides of the page. The result? Inconsistent
quality, more frequent misfeeds and jams during duplex runs, and diffi-
culty meeting deadlines. Compounding the problem, slower, single-pass
cut sheet devices are more costly to own and operate.
Océ Gemini Instant Duplex technology.
A breakthrough in high-speed, duplex digital printing
Clearly, duplexing is a critical component of any print provider’s
productivity equation. But not all duplexing technologies are created
equal. Given the problems associated with printing duplex jobs on
simplex machines and the fact that most high-volume output is duplex,
wouldn’t it make sense to build a single duplex engine?
In fact, duplexing comes in two flavors—dual-pass duplexing on
simplex machines (the de facto standard until recently) and revolu-
tionary Océ Gemini Instant single-pass duplexing, an advance that
represents a watershed moment in professional printing. What’s the
difference between the two … and does it matter?
In answer to the first question—the difference is a quantum leap in
quality, productivity, and reliability. As for the second question, it
matters a lot if you care about reliability, throughput, or time to market.
Despite the fact that most jobs are produced in duplex on high-volume
systems, all other cut sheet digital systems have been designed for less
efficient single-sided printing. In these systems, paper must pass twice
through the print engine and fuse the image at least twice to produce
duplex sheets, creating reliability, speed, and productivity issues. Not so
with Océ single-pass duplexing, which enables print providers to
increase speed and productivity while eliminating overtime, freeing
employees to focus on other work.
Duplexing:
the Fast Track to Exceptional Productivity
Consider the Océ VarioPrint® 6250—the world’s most productive
digital duplex cut sheet printing system with the Océ Gemini print
engine. This innovative new technology comprises two imaging
modules encased in a single engine that simultaneously prints both sides
of a sheet of paper to achieve near-perfect registration. The technology
also enables a 70 percent plus increase in output.
Because the images on both sides of the page are transferred and fused at
the same time, less stress is exerted on the substrate and reliability is
exceptional. The combination of single-pass duplex printing and a
fusing temperature well below that of competitive electro-photographic
methods further reduces paper stress and eliminates paper curl. The low
fusing temperature also helps with finishing, by maintaining adequate
levels of humidity within the paper to reduce the risk of jams. Bottom
line—with Océ single-pass duplexing, pneumatic paper feed technology,
a short, straight paper path and lower fusing temperatures, the Océ
VarioPrint 6250 can handle an impressive range of media.
Print providers benefit from high productivity, greater operational
efficiency and lower printing costs, for more efficient short-run
production of training manuals, technical documentation and other
essential business applications. Duplexed tabs, cost-effective color
inserts, and professional finishing capabilities, like fusion punch and
square fold booklet making, open up an even wider range of work.
