This is my first post. I hope this isn't posted in the wrong place or isn't a repeat question.
I work in a label shop and we have two Jetrion, Digital, Roll-to-Roll presses. Something I run into over and over again is brown mixes and gray mixes varying from one head to the other. The problem is magnified if you are printing on top of white when using any material that is not white (silver foil, clear etc.).
The problem as I understand it is that browns and grays are a mixture of all four colors. Add that to the fact that you have three separate printheads spanning the width of your print that must be working in perfect sync with one another (output of all four colors and their respective percentages) in order for a solid gray or brown to appear consistent. This often results in some areas of the print having more magenta (for example, this applies to all except black). I should mention this is only in jobs that have a solid color background: meaning the label has a gray or brown background with black text(for example: the black text is irrelevant to the discussion). And especially in cases where it is white behind the solid gray or brown.
I am asking if you have solutions other than to operate in the utopian world where printheads are always aligned and calibrated perfectly, clients know better than to order browns and grays on digital, and unicorns re-set type for me HAHA. In all seriousness though are there certain CMYK mixes that result in more consistent browns and grays?
I can go into more detail if you guys are unclear but I don't want my query to be ignored for it's lengthiness. Plus if you are experienced in digital production I am sure you have run into the same issue.
PS I can post a picture of the specific artwork in question. But once again I think that specialist, such as yourselves, will understand that this is a non-artwork specific issue.
Thank you so much for your time.
