The installation of our 4 colour Direct Imaging (DI) printing press is
changing the way we meet our customers’ demands for their printing be it single
colour or short-run colour. This proven technology produces high quality offset
printing, in the least amount of time, with the least amount of labour and
materials.
Q. What is DI?
A. DI is an acronym for Direct Imaging. A DI press
is connected to a Postscript-based prepress system in a similar fashion as a
laser printer — the press becomes another computer peripheral. The Postscript
data is used to simultaneously image the four printing plates in register,
directly on-press.
Q. Why DI?
A. DI cost-effectively provides the quality,
quantity and quickness, that print buyers require. Our DI press provide the
convenience, economics and turnaround of toner systems, but surpass their
capabilities with the higher quality and greater capacity of offset printing,
with the added bonus of being environmentally friendly.
Q. How does DI printing benefit the environment?
A. Direct Imaging eliminates hazardous waste
material right up to the final step of printing. Film and chemical processing
are eliminated. The plates are non-photographic and used plates are recyclable
so disposal problems associated with heavy metals are gone, as is the cost.
Since DI is a waterless printing process, fount and alcohol substitutes are eliminated.
The very quick makeready time of DI presses significantly reduces paper waste.
Q. What exactly is DI technology?
A. A successful DI strategy is a combination of
three core technologies working in unison —1. laser imaging, 2. thermal plate
and 3. press design. This process requires the fewest steps from digital file to
plate, eliminating the need for a safelight environment, reducing waste and
removing chemical processing from the plate making process.
Q. What are the benefits of Direct Imaging?
A. Our DI press enables us to be more competitive
in a market that continually demands faster turnaround time, shorter press runs,
and expects lower cost without sacrificing quality. It is a very cost-effective
method of printing one, two, three or four-colour jobs at run lengths from 200
to 25,000.
Q. What is the difference between a DI press and
digital printer?
A. They are two different technologies. Digital
printers, such as HP Indigo and Xeikon products, are toner-based printers that
provide copier quality in run lengths of less than 500. Our DI press offers true
offset, lithographic quality - ink on paper in quantities of 20 and greater.
Digital printers are limited to the stock that they use, while DI presses use
any stock from onion skin to heavy board thickness. With a digital printer each finished piece has a
fixed cost, while DI presses are designed for production printing. DI presses
are clearly the highest quality and most cost effective solution for all types
of printing.
Q. What can be printed on a DI press?
A. Anything that can be printed on a conventional
press from single colour to full colour, can be printed on a DI press, including
stationery, catalogues, books, documentation,
sales literature, point-of-sale displays, cards, packaging, and forms. We’re not
limited to paper and board stocks, either. The DI can print on labels, plastics
and Tyvek, and we
can even use the DI for lenticular printing to produce direct mail with a
three-dimensional appearance.
Q. What level of print quality can I expect from a DI
press?
A. Our DI press delivers higher-quality offset
printing. With output at 2540 dpi with 300 line screen in comparison to the 600
dpi from toner based systems. In comparison to traditional offset printing
methods, DI delivers higher quality because the DI production process reduces
manual intervention and the number of iterations between the original and
finished plate. The instabilities associated with conventional production
methods, such as emulsion variances, processor condition, and ages of chemistry,
have been eliminated.
Q. Are DI presses suitable for versioning?
A. Due to the fast plate changing and excellent
registration, DI presses will easily address your versioning needs. For example,
a sales brochure can easily be printed in multiple languages, simply by changing
the black plate.
Q. Are there any special requirements for clients
submitting their own files for printing on our DI Press?
A. Printing to a DI press carries many of the same
requirements as printing to a traditional press. You should start by talking to
us. Before sending the job please make sure you have completed an output form
giving details of the job, include all fonts, or convert fonts to outlines,
images supplied in CMYK, checked bleed sizes and any trapping.
