    hello everyone I am a newbie here and I want to ask something regarding RISO printers. I have always heard about it and one of my friends even ask me about it but I didn't have an answer coz I don't know about it. Can anyone tell me the difference of RISO printers from ordinary printers? :confused:

    I'm not sure exactly what you mean by "ordinary" printers.
    The most common ordinary printers are probably desktop inkjets which have an inkjet head or a pair of heads that moves back and forth on a guide bar across the sheet making pass after pass as the sheet moves through the printer. Quality is good, cost is high per print, cost of the machine is very low, and time per print is very slow.
    Riso's background is in digital duplicators. These print a master which allows ink to flow through it from a central ink cylinder onto sheets at a high speed, low cost per print, low quality, fairly low cost for the machine. There are two color digital duplicators that can print a color line drawing or one color logo against a different color of type or simple two color envelopes.
    Riso was early into the inkjet market with the forcejet or comcolor. This uses a line of inkjet heads across the sheet to print quickly. Cost is about what you pay on a click contract, but you don't need a contract. For light coverage the cost is very reasonable.
    "RISO ComColor high-speed inkjet printers employ 24 in-line Piezo drop-on-demand print heads. Each of the four colors (cyan, magenta, yellow, and black) has six print heads in a row imaging the page."
    The ideal use of the Riso inkjet is something that has variable data or some light color coverage that you need high speed, low cost, and not a long enough run per unique run to pay the cost of plates and press for offset printing.
