    Considering purchasing a QM DI 46-4. How well do the inks apply on one blanket? Can you run heavy full coverage images without much problem? Would really appreciate feedback on the pros and cons of this equipment.

    Thanks :)

    Hi sir
    Good morning.
    Heidelberg QMDI presses are fully automatic 4-color, sheetfed, waterless digital printing presses.
    These presses eliminate the expense of film, the making of plates and everything associated with off press imaging.
    Because there is no film, you save time, money and labor.
    Digital files are sent to the press via a high-speed network. These digital files are imaged in register directly to a plate already mounted and advanced on each of the four plate cylinders on the press.
    The QMDI press can cost effectively print four-color preocess priniting in quantities 500 to 25,000 up to a maximum image area of 13 by 17.75 inches at up to 10,000 impressions per hour.
    The Heidelberg QMDI press's digital technology in addition to its unique compact design, make it an ideal addition to any pressroom or small copy shop.
    Of course support after sale.
    Back to me any question or doubt

    Having worked on this machine as a Heidelberg representative since its inception there are a few more things I would like to add to Chock's excellent review of the machine.

    In it's day the QMDI was a revolutionary piece of equipment. Keep in mind the last one came off the assembly line in 2002. This means the newest one you can find is 15 years old. It's service life was thought to be in the neighborhood of 30 million impressions, although there are many out there that were well kept and are way beyond that number.

    There were 4 versions of the machine produced. The Classic was manufactured from 1994 until 1998 it's serial number range was 990001 - 990908. Next the Plus was released fro 1998 until 2000, serial range 990939 - 991595. Lastly, there were 2 versions of the Pro machine; they were manufactured from 2000 until 2002. The first version was just called the Pro, serial range 991596 - 991858, the last version was the Pro Spot, serial range 991859 to 991910. The Pro Spot had a laser diode that fired a smaller dot for better resolution.

    The cons for the Classic is it only had 8 ink keys, and the press PC in the earliest versions was a 486 up to SN# 990188 (Try and find parts for a 486...they are even difficult on Ebay.)

    The Plus had 12 inks for better control, it imaged at a higher speed and the feeder decoupled while imaging (To save on wear and reduce vibration during imaging.), although it only had a Pentium 1, not much better than a 486.

    Both the Classic and Plus have a direct feeder. There are no front lays or pull guides.

    The Pro was the pinnacle of the QMDI, although by the time it was introduced, CTP plate setters were readily available and affordable, thus signaling the demise of direct to plate on the press. The Pro had a feeder like the SM52 with front lays and pull guides. The Press PC was better although 17 years later it is hard to find parts for it also. It had multiple imaging features and it's delivery decoupled along with the feeder during imaging. The press console had a CP200 touch screen for operation.

    Lastly, there are few of us left who work on these machines. The Pro has to have a special program for service personnel to connect to it for troubleshooting. I do not even have a functional version of it any longer. On the positive side, there are plenty of used parts for these machines around as many have been dismantled to fill the part void.

    If I were to buy a QMDI today I would get a Pro. Although, I would much rather have an SM52-6+L with a Suprasetter...
