OFFSET PRINTING SECTION

  • Three (3) Rislan covered vibrator rollers.

  • The vibrators are a rocker arm assembly drive from a rotary input which eliminates the need for individual gear box drive for each vibrator. This eliminates the possibility of gear streaking and dot slur due to surface speed variation if a vibrator gear box wears or is damaged due to a paper wrap-up.

  • The vibrator stroke is fully adjustable from 0" to 1 1/2".

  • Two (2) dedicated ink form rollers and one (1) ink/water form roller in the dampener unit.

  • MIYAFLOW 3 roll continuous dampening system consists of a rubber pan roller, a chromed metering roller and the water/ink form roll.

  • All ink rollers can be covered with UV compatible material.

  • Tool less ink and water adjustment is a standard feature.

  • Automatic ink wash is  a standard feature. The unit comes complete with two tanks so that UV and normal solvents can both be used.

  • The offset tower comes complete with independent unit drive for ink up, auto wash or unit preparation while the press is printing a previous job.

  • In addition to print register adjustment using the 10-key on the main operating panel on folder unit, individual units are equipped with button which enables operator lengthwise and lateral adjustment in both rough and fine adjustment by keeping pressing the button as needed. This feature ensures further waste reduction at starting up.

  • Motorized plate cylinder lateral registration is controlled by push button at each offset tower or at the main operator console.

  • 360° circumferential  register control is accomplished by harmonic drives on each tower activated by push buttons on each tower or the main operator console.

  • All offset cassettes are mounted permanently  on their own dolly and simply roll out of the press for a size change.

  • Zero position can be achieved for wash up or plate change with the press returning to its previous position or to zero position by one touch of a button.

  • All offset cassettes can be equipped with sticky back blanket cylinders or reel rod style.

  • All of the offset cassettes are bearer loaded.

  • Letterpress and numbering cassettes are available for use in any designated offset tower.

MULTIPLE FUNCTION PROCESS SECTION

  • The dual pull rolls at the entrance to the process unit and the pull rolls at the exit of the process unit are can be ratio adjusted. Using the Miyascale 750 to set the in and out tension ratios can improve print registration and fold pack quality on light and heavy weights of paper.

  • Lengthwise adjustment on file punch and lengthwise and lateral adjustment on marginal punch are possible on CNC.

  • Lengthwise perforation and slitter are fixed at 1/4" from the center of marginal punch which requires no adjustment at all. They move as the marginal wheel moves. Of course, lengthwise perforation can be put at any position by using the units located at the entrance of processing unit.

  • two positions for vertical perforations or slitters. Each position has its own hardened anvil cylinder and holder shaft. The holder shaft is pneumatically operated for on/off operation.

  • One position for file hole cassettes.

  • One position for marginal punching. This unit will be equipped with Miyakoshi punch reels. The unit will be configured for single-single.
