Best way to determine tolerance is usually based on actual press data. You could have the printers aim towards a provided ink drawdown, and run the densities from low to high to determine your tolerances (the ideal density that yields the closest match to the target, as well as acceptable low and high density aim points). SpotOn makes a good tool for this. http://spotonpress.com/spoton-spot/ Mike On Wed, Aug 8, 2012 at 8:14 AM, Terry Walker <prepper@netzero.com> wrote:
Hi all,
We publish a library of books with a different PMS background color for each year. We have 14 PMS colors picked for this and have printed them now for 11 years. When we started out we didn't have a spectro to measure them with and over the years colors have drifted thru new ink companies, papers, etc. and just plain on press variations which seem to be worse lately. We now have a spectro and can measure the Lab values of these inks and have a "good" reference point to use going forward.
My question is, I know the press printing tolerance for cmyk solids for Gracol is dE of 5, what would you suggest for press tolerance of Pantone solids?
Most all our colors are darker shades. Some of our main PMS #s are 5605, 5255, 229, 140.
Any suggestions on what would be an acceptable dE range for these?
Thanks
