We are currently running a job with a large red background ( spot color ). Our problem is whenever we get the colour close to our approved colour we find that the next day the colour lightens or appears matte.
We've used inks that are mixed in the plant and inks mixed at our ink supplier and we get the same results. As you can imagine it is very difficult matching the colour if changes when it is drying.
I've read in "Solving Sheetfed Offset Problems" that this is due to not enough oxygen for complete drying and heat generated from the drying process but would like to know what are other possible caused of the problem.
Thanks
