I thought so. Currently, he is using all colors CMYK, + in the original setup. Not "refillable", cartridges, but he replaces each one as needed.
Does the ink coverage come out (as deep) and dark using just all black? It's pretty opaque now as it is. I'm wondering if he does it for ink coverage (opacity) or maybe he does simply doesn't know you can switch it to just black?
Have you noticed a difference in cost savings using just black? He probably puts out 24x30" films at 20 sheets a day.
By the way, these things are soooooo slow at printing films. Sheesh. It's like 3 hours to print one 9 color job. Back in the day, using wet photo film/Imagesetters, it would take about 30 min to raster and then it would spit them out. about 30 min total. MUCH faster and higher quality but the machine was more costly and did have more prep and maintenance. I think he has the highes quality setting right now. How much different is the lower quality setting? he uses 53 lpi on most and 75 lpi on others.
