The files I supplied were vector, I suspected it was operator error but had no way to prove it, as for color management I use the swatch system set up by Roland, you have to design in cmyk, Roland supplies a file for Versaworks that you print out on the media you use commonly, it has your actual serial number of your printer on the file, then you take this big sheet to your cutting table & cut it up & punch a hole in each one put a zip tie through it & now you have a swatch that is color matched to YOUR printer with your favorite media, then you load the swatch pallet into illustrator and while you are designing you can show your customer the swatches, it looks a lot like my pantone swatch I use that cost me a hundred bucks but anyway when I choose a color from the swatch no matter what it looks like on the screen it prints out matching the swatch. You can make this swatch with all the different types of media you use & just pick the number on the color & it matches, I don't know what system gerber uses but would imagine every manufacturer has something like this
As far as the "home run" job you did with your gerber congrats, but I think for the local small sign shop you get more traffic on the soccer banners, truck & van lettering, lighted sign faces etc, now you have to agree that 54" wide printing gives you a lot of versatility for a wide range of jobs, even the 540 cut the sandblast mask but I am sure it didn't do it as handily as the graphtec would. My point was for the money you can cover a wider range of jobs with the same money with a VERY nice looking product. I was making signs 10 years ago & at that time wanted the gerber, but held out & subbed out till I couldn't take waiting etc. You gave me an example of one specialty job that you could cover with a specialty printer, I make signs, most of them are bigger than 2x3 & I wouldn't want to have to use a 15 inch printer for them, as for the color matching I didn't think many Roland users were using the Versaworks matching swatches after reading the rgb-cmyk thread but I didn't want to get into it at that time, I have no doubt the Gerber has it's place in the industry but my idea is toward the over all average of jobs walking in through the door of the local sign shop but if I would have had a call from printer like you did I would have made a different choice, I guess you have to monitor what jobs come through the door & make your choice accordingly.
