Hi
[email protected], another copier technician-offset printer wannabe, well that makes two of us
. Things that you need to figure out and present to folks here are:
Size of the sheet that you need, what kind of stocks, how many jobs a day are you planning to run, how many impressions each... There are machines that have their own pros and cons.
Any press - be ready to clean, wash-ups, even with automatic wash-up devices.
if 12x18 format is withing your interest then depends on your jobs criteria you have a choice of 100% digital Press - Imaging huuuuge color laser printer. Than, there is Indigo which is sort of what we get if color laser printer and offset press were married and had a baby, than there is a DI offset press ( I think, it will fit your original request and PressTek makes 14x20 DI press. Still would have to wash it though. There is a problem with PressTek- many many printers hate it for what they did to company called AB Dick - do your research If interested).
If you seriously thinking about Offset - best way, I think, go trough some Printing courses or school, if you can. I still sell and service copiers and have printing shop ( no 4C presses) for 3 years and wish I'd find time to go and learn a little, but I really dig in to those things - I fix most of problems myself, I read , I research, try fix, fail - read more...
finally I get it, nothing super complicated. If you think you need bigger size of sheet, like 14x20 and bigger those machines would require you know some to lots of things and getting one without proper knowledge could make you a slave to service company. Anyway, hope I helped a little, Good luck.
