Digital presses consist of imaging lasers (or LEDs), new plates, photosensitive drums, and inks. The models offered by different suppliers range from high-speed laser printers to traditional offset printers, with a wide range of functions and printing methods. Digital presses can not only print files directly, but also automate file management, eliminating the time-consuming and costly process of film output, printing plates, ink preparation and calibration, saving time and cost. These printing methods combine professional printing with desktop systems to achieve short-term, four-color printing with short cycle times, high flexibility, and good economics.
Short cycle
Depending on the binding method, in general, an experienced digital printing factory can shorten the printing cycle to 48 hours or less.
flexibility
Since the plates or photoreceptor drums in the digital printing machine can generate images in real time, the files will not be lost even if they are modified before printing. An electronic plate or photoreceptor drum allows you to print while changing the image or text of each page so that the content of each page is different. This is called a personalization function. In addition, electronic files are sent to other locations where you can print anywhere in the world. If you have thousands of pages of 50-page booklets that need to be distributed at the year-end meetings, this type of printing can solve your problem of shipping these prints.
Four-color short print
Digital printing eliminates the vast majority of prepress preparation in traditional printing, making four-color short-run printing - whether it is 5 or 5,000 copies - at a reasonable price. Although digital printing is more expensive than traditional printing in terms of printing leaflets, the same short-run business will be more expensive if it is done using traditional printing.
limitation
Most digital presses do not have as much expressiveness as traditional seven-color printers, so the design of four-color files should not be too complex or deliberately pursue color accuracy. These new printing presses are not intended to replace traditional printing but are aimed at some markets that traditional printing cannot afford.
When to choose digital printing
Digital printing is suitable for four-color printing jobs requiring short cycles and high flexibility. In some cases, such as designing coupons and producing marketing materials, using digital printing will achieve good results that cannot be achieved by other methods. If you want to customize the content of each page, for example, keep the same text on each page of the real estate sales data, and replace the different photos, digital printing will be your best choice. At present, digital printing has only just begun. With the development of computers, lasers, printing plates, inks and other technologies, digital printing will provide more new features.
Comparison of digital printing and traditional offset printing process:
offset printing
Design and file preparation → Digital proofing → Photocopying → Film proofing → Platemaking / imposition → Printing (print proofing) → Finished product
Digital Printing
Design and File Preparation → Digital Proofing → Printing (Print Proofing) → Finished Product
Traditional offset printing requires a lot of time, manpower, and material resources to produce high-quality color prints. When printing large quantities of prints (more than 5,000 copies), traditional printing is often more economical than digital printing, and it can provide a wide selection of inks, paper, and other printed materials. However, because of the large amount of preparation required for traditional printing, four-color short-run printing is often uneconomical.
Digital printing eliminates the need for film and automated prepress preparation, and the press can provide proofing directly. Because the plate or photosensitive drum can be imaged in real time, it is possible to modify the contents of the prepress file or change the contents while printing. Since digital printing does not require a lot of manpower and processes, the level and experience of operators is very important for high-quality finished products.
