Best suited 2 colour machine to do 4 colour jobs in A3 size

I am looking for a 2 colour press on which 4 color jobs will be produced the size of the paper will be A3 + or 15 x 20 Please suggest the machine

 

any press with good adjustability on the side guide (preferably a PULL guide) and a good setup for keeping the sheet in the headstops will work fine. As presses get older and worn they loose a little of the precision required to keep the close register tolerances required to do this with any success. Test print anything you consider purchasing with an eyed towards the presses ability to register on multiple pass printing. My preference leans towards the German engineered presses but ive done this kind of work on komoris and even solnas with good success.

 

GTOZ. No contest. If you can't afford one, try a Ryobi 3302, or even it's predecessor the Itek. Printers the world-over bought either of these presses and produce CMYK to great effect.

Main points are - good register system and true 2 colour printing. Don't consider a Printmaster or anything like that. Common blanket presses will start off looking ok but after a few sheets have gone through, the ink starts to migrate and contaminate the light colour. You might not notice it until it's too late.

Rolling power is important too. GTOs have 4 form rollers per unit and the inking is far more forgiving as a result. It's easier to maintain colour.

 

I think sm 52 is the best you can do full color jubs at full speed 15000 so i think this is the best option full automatic wash and verry quick color change
