The other thing to think about is that when an offset run is done, you pay for all 250 or 500 or whatever in one shot.
When you have a giclee made, you can have 1, 10, or 100 made at a time allowing the artist to test the waters, so-to-speak.
Yes, each print will be more than the cost of each offset but the quality is considerably better and thus can be sold for more than the offset one would. I do this for artists along with my framing business.
I have a 4x5 transparency made of the original art and then I scan the transy into my computer. You can't make a really good scan with the average desktop scanner. You will not get the quality you need.
I have a Creo scanner that costs more than alot of the cars on the road in Maine. ( Of course, looking at most of the cars up here, that wouldn't take much!!)
I then print the art on my Epson 9600.
The best part of this is that while the printer is working, I can go back and continue framing. I don't have to sit and wait.
The last pieces I printed were 9@ 28x42 and took just over an hour for each to print.
So far, I'm only working with artists in my area as I like to have the original here with me so I can compare it to my print.
