Ryobi 582 Offset Printing Press 2 color

Printing press in action. 17.5"x22.5" sheet size 13,000/hour max, 2 color. Can do tight registration 4 color process printing.

Very much a Rube Goldberg machine, fascinating to watch it grab just one sheet at a time and position it just perfectly in a quarter of a second!

What kind of an offset would I need to print 24 inch by 36 inch posters? And how much would it cost?

[ryobiguy]

Dunno, something way bigger. This machine is just under half of that size, and the ballpark price I heard was around a quarter of a million US dollars in 1995.

[LuxuriousLuxembourg]

shit man, thats a lot. I wonder what the price to make a poster of that size cost at least. to see if its even worth it or not. but dang back in 95. I see a printer by HP for around 8 to 12 grand that does it, no idea on how much ink it would use up.

[ryobiguy]

Well, offset printing vs. inkjet (or some other similar technology) is very different.

If you're making thousands of them, it makes sense to use offset printing.

If you're making just a few here and there then offset printing probably doesn't make sense.

Plus, this is only a two color press - the sheets have to go through twice to get full color, "4 color process".

[ryobiguy]

So offset printing requires a big machine, lots of labor, but makes sense when you need a lot of the same thing. Even though this press's top speed is 13,000 2-color impressions per hour, it make take 2-4 hours to get 5000 sheets printed.

(Plus overhead of end-of-day time washing the rollers, cleaning all the rubber and chrome working surfaces.)

Nice Ryobi stream feed too! We have the 3302 and 3304 at my school's press shop neither are stream fed *crys* That's really sweet though

[ryobiguy]

I also worked on a 3302, was a fun machine to run, when it was working well... I spent a lot of time messing with the infeed roller pressure (under head of sheet) and the infeed cylinder grippers to get register just right. Make sure you've got good rubber on the infeed rollers, makes a world of difference.

On 3302, there's a rod that's too close to the rollers and builds up ink (presumably from sloppy washup) and drips dirty ink into into the rollers, had to clean frequently.

@HachiZenki web presses suck compared to sheet-fed presses, because of the constant drone of a web press. Besides, it takes a team of people to run a web press.

I am worked in Ryobi 750 good and excellent printing mashine short wastage and good production sugathan kc kunnamkulam

[enfantdusoleil100]

whaaaa ^^ je travail sur une rioby 725....heu je vais pas a cette vitesse ....bravo pour le reglage de la marge ...;)

[sama73]

that is only copy,not printing!

[Fentanyl3]

@geroldkid LOL, run millions of impressions a week, most all of them are very close, or above 13K IPH. Smashed grapes color ramps off, etc are tossed and our ship out scrap is below 0.3 %

[HachiZenki]

Disaster at 13K iph? You gotta be joking me. Try seeing what a web out + wrap up will do to a press at 28K iph.  Esp. if the damn operator ain't paying attention and is spacing out.

@Kostagh How much is that machine? Nice not bad thanks for the information. :)
