Introduction A new way to look at documents One of the greatest advantages of digital colour applications and systems is that they allow high-quality colour process printing to be produced in smaller quantities at a higher frequency, as well as personally tailored printing to optimise customer interaction. Digital printing technology changes the way we think about and create documents. Limitless possibilities are now accessible for full-colour, near-offset quality printing at a reasonable price

1 Digital print Digital technology has changed many facets of business and industry today. Computing and communications technology has allowed companies to revolutionise the manufacturing process – from producing goods and then hoping to sell them, to just-in- time production, where products are sold first and then manufactured to order, reducing waste, inventory and cost. It has also allowed them to produce products more in tune with individual customer’s needs, moving from mass production to

What truly distinguishes digital printing from traditional printing is the ability to print every page differently. This is something that offset presses – including DI presses – can- not do. Offset presses can only print exact replicas of the same sheet, again and again. The digital colour presses that dominate the market now – and for the foreseeable future – are all toner based. They utilise electrophotography, either with liquid toners (Indigo), or dry toners (IBM, Kodak-Heidelberg, MAN Rola

digital print Digital print workflow The entire process for the production of a printed document can be broken-down into three phases: prepress (which includes all steps after the design is completed up to the point where the job is printing), press or printing (the printing phase), and postpress or finishing (all the steps required to finish the job after printing and before distribution). Digital printing has greatly simplified two of these phases: prepress and press. For an understanding of

A proof can be produced on a digital device (like a DocuColor printer or inkjet or dye sublimation system) or using a photomechanical system (like Cromalin). The advantage of digital systems is that they have a lower cost and quicker turnaround, and they better fit the digital workflow most use today. However, photomechanical systems are still used where film is an important part o

digital print Press The job is now at the stage where it’s ready to be printed. If the job is being printed on a DocuColor 2045 or 2060, the operator will have calibrated the press earlier in the day and loaded the right paper. The job is then RIPped (using the appropriate settings) and printed. It doesn’t matter whether you want 1 copy or a thousand, the process is the same. On an offset press, the operator needs to set the press to make it ready for printing (called makeready). This process ca

With the DocuColor 2045 and 2060, you’ll make the change to the file and re-submit the job. The printer will re-RIP the job and print it. Done. With the traditional offset process, you would also change the file and re-submit the job. Now the printer will have to create a new set of film, new plates, set the press up again, and then start printing. More steps for something to go wrong and more waste produced. What does digital print mean to you? New opportunities: added document value combining

digital print The DocuColor 2045 and 2060 now allow consumers of print to have high quality colour work printed cost effectively on short runs – anywhere from a one-off up to 2,000 copies. You no longer have to buy long print runs to drive unit costs down. Because a digital press prints each page differently, you can even print one book at-a- time in a single print run. Examples of applications now possible with digital printing include: •Short run books • Limited run video covers and CD labels

As the life cycle of products gets shorter and shorter, it means that with digital print you will always have the latest, most up-to-date, accurate and relevant support material and publications. It allows you to frequently update the content of your printed material and print small batches of the latest version, avoiding the distribution of incorrect or out-of-date material. Examples of applications suited to the just-in-time advantages of digital printing include: •Manuals •Brochures • Catalog

digital print Variable information printing A unique characteristic of digital print is the ability to print every page differently. Not only does this mean you can print a multi-page document (like a book) in a single print run, but you can also personalise each sheet or page to an individual. It is achieved by changing certain text (like name and address) and/or images on the page. This new capability is called variable information printing (or variable data printing), which people may also ca

Use of colour Colour attracts attention, increases impact, stimulates emotions, and touches us where pure reason and intellect do not. Use of colour in documents improves understanding and comprehension, helps organise data, and aids the reader in decision-making, learning, retention and recall. Numerous studies back the power of colour. Ronald E Green (The Persuasive Properties of Color, October 1984) showed that colour sells products and services better by up to 85% and provides savings in tim

This section includes a description of the technology that’s built into the presses that allows them to deliver on their promise as well as providing information on some of the capabilities of the DocuColor 2000 Series that will help you in designing documents for the press. This includes topics such as size considerations, print s

Digital Blanket Significant improvements in image quality can be attributed to the Digital Blanket used in the DocuColor 2000 Series. The Digital Blanket passes under the four printing stations where the image is transferred to the blanket. The four colours of the image are assembled on the blanket – one on top of another in perfect register – and then transferred to the paper in a single pass when the blanket passes under a pressure roller. The uniform, flat surface of the Digital Blanket reduc

image reproduction process TRACS To ensure consistency from first print to last, the DocuColor 2000 Series utilises a technology called TRACS (Toner Reproduction Auto Correction System). TRACS automatically measures 16 levels of density and colour, and makes adjustments on the fly. TRACS works by placing CMYK density patches directly on the Digital Blanket between pages as they circulate through the machine. These patches are then read by built-in auto density control sensors, and any quality ad
