Digital printing & previous print processes
Digital printing is increasing in addition; its use is spreading with the increasing and continuous development as a result of the emergence of modern trends in the field of printing and publishing. The trend has increased the use of computers in digital printing systems which increase the degree of color control and consequently the high efficiency of printing and increase the clarity and consistency of colors. Unlike previous print processes, where in most cases all the necessary ingredients to colour the fabric are mixed together, thickened and then printed, digital printing normally involves pretreating the fabric with the fixing agent. The digital printer then prints only the dye or pigment colour. Digital printing varies from conventional forms of analog printing — like offset printing — because digital printing machines do not require plate printing. Instead of using metal sheets to move an image, automated printing presses directly print the image onto the media substratum. Digital print technology in production is developing rapidly, and the quality of digital printing output is constantly improving. These advances deliver print quality which offset imitations. Digital printing provides more advantages including:
- Custom, Variable Data Printing (VDP)
- On-demand printing
- Cost-efficient short runs
- Fast turnarounds
What is the digital printing & how does it work?
Simply, digital printing is the print that transfigure the digital system, file or image file such as a jpeg, PDF, word, excel, Photoshop, etc. that was created on a computer and then sent to a printer to create a physical print using CMYK ink . By transfers it to the printing system, which performs a cycle in transferring the printing to the raw materials that will be transferred to all digital data on which the image is stored on the computer to the printer, which in turn receives that data and translates it into the image to be printed.
Digital printing is the last generation of the process of developing and upgrading the Xerox camera that took stencils out of the office print market forever. They are called digital because they rely entirely on the micro-transistor (micro-chips) for ink and paper control operations. This very advanced technology allows preparing and producing documents and printing them directly onto a variety of media substrates, in black and white or other colors, directly from the computer to the printer. There is no need for a printing plate, unlike with offset printing. Digital files such as PDF or desktop publishing files can be sent directly to the digital printing press to print on paper, photo paper, canvas, fabric, synthetics, cardstock and other substrates. It also is a highly versatile technology which has great potential in textile design and patterning Flexible digital inkjet systems have been developed that are designed specifically for decorative applications.
Digital printing has a lot of advantage as its technology excels in quick and cost-effective output on demand, and short printing. Digital printing is also a perfect customization tool. If you want Variable Data Printing (VDP) to easily modify images and messages, then digital printing is the only way to go. With advances in print quality and speed, the disadvantages of digital printing are rapidly disappearing, and digital printing presses are closing the gap in offset output.
Digital printer & its media types
There are many types of digital printing devices, including industrial printing presses such as sheet-fed industrial printers, digital cut-sheet presses, inkjet printers for manufacturing, and continuous feed printers. Some of Xerox’s recognizable brand names include iGen, Iridesse, Versant, Nuvera and PrimeLink output printers and digital presses, as well as Xerox Brenva, Baltoro, Rialto, Trivor and Impika production inkjet and continuous feed printer.
Everything from dense cardstock, heavyweight papers and folding cartons to cloth, plastics and synthetic substrates can be printed on digital printers. T-shirt printing is a very common digital printing application, and in addition to T-shirts, some digital printers can print on other fabrics, including linen and polyester.
Digital printing inks
Digital printing inks include toner and ink cyan, magenta, yellow and black (CMYK), and extended color gamut inks such as orange, blue and green, as well as specialty dry inks for metallic, white or clear effect.
In reality, digital printing is an alternative to traditional forms of printing, such as flexography, lithography, offset printing, letterpress, gravure and so on. The process eliminates most of the steps required for traditional printing methods such as
Color proofing, film making, printing plate making and manually stripping the pieces together. Compared to conventional methods, digital printing is simple and highly efficient, and comes with numerous benefits. Therefore in this day and age the process is so common.
Note: The CMYK process model uses three primary colors of ink: cyan (blue), magenta (purple/red), yellow and key (black) to print colors. When printing these as solid colors, seven different colors are possible.
