Offset and Digital:

          Cost vs. Capabilities

At some point in the print-buying process, there is a question of what printing technology to use. Should it be printed on an offset press or a digital press? It’s an important question because both are capable of brilliant print quality, but there are differences in paper and finishing options as well as costs.

Offset presses do most of the printing in the world. Magazines, commercial greeting cards, books, and mass-market collateral are printed in volumes that make offset printing cost-effective and efficient. The presses may print sheets or rolls of paper using printing plates that contain the print images for each of the ink colors, usually cyan, magenta, yellow, and black, but many presses also support additional spot and specialty colors. As the paper moves through the press, the plates in each printing unit pick up ink and transfer it to the paper. The paper moves from one color station to the next, building the image to create the final intended printed product.

The nature of the technology means that there is significant preparation before printing. Creative files are put through file preparation and color management processes to ensure the file is print-ready for offset. Color separation files are made for each color, which are then sent to a computer-to-plate (CTP) system that images the aluminum plates. After imaging, the plates are processed and mounted on the press. Many plate imaging systems require chemicals and clean-up fluids that add time, effort, and cost to the job.

Offset printing produces very high-quality print, in print runs that often go into the thousands and sometimes millions of pieces. It is a technology that supports almost any type of paper, any weight, and any finish. This is the technology most often selected for static printing that requires long runs because the cost model is appropriate. Plates and the cost of makeready become a smaller percentage of the total cost when higher quantities are produced.

The calculation changes when the print runs are short or when the work requires variable customization. That is where digital printing options are best suited. Digital devices use imaging modules that transmit information to inkjet print heads or electrophotographic modules that result in print on paper.

The most striking difference is that digital printing does not require the physical makeready – color separations, plate making, hanging individual plates, and running tests to ensure color registration – required in offset printing. There are file preparation requirements, but no plates, no chemicals, and less time to get ready to print. The image file is delivered to the Digital Front End (DFE) of the digital print device for final imaging and for communication with the print engine.

Digital technology is based on either inkjet heads that drop ink onto paper or imaging modules that transfer an image to a charged drum to attract toner that is transferred to the page. Each technology behaves differently and has slightly different color models because of the differences between toner and ink. Digital print also supports a more limited set of paper stocks.

Variable data print products like bills and statements, where every page is different, are done on digital print devices. Direct Mail is often printed using digital devices, especially if there are variable offers to target recipients. By comparison, if you were doing big box store coupons that only vary the name and address, you might print using offset technology and then add the name and address using digital technology, which could also impact your costs. Digital printing is becoming the technology of choice for short-run static work, book-of-one or personalized books, and personalized training material.
