Okay folks, having a bit of bother with a print job. Sent a piece to print but was told by the printer that the black was too dense for 170gsm stock and that I would have to upgrade to 300gsm. Now, I agree there is a lot of black on the leaflet with a make up of 100K & 40C. When I called back to discuss the job I was told by someone else that normally that amount of black would not be an issue, but rather it was something to do with something needing tightened on their presses as it wasn't picking up the paper properly and smudging. As you can imagine, having to upgrade from 170gsm to 300gsm for 40k leaflets is a big jump in costs. Can any printers comment on this? Jpeg of artwork attached to show amount of black.
