Side note....I sure miss Joe Clarke's base. Best I ever used

"Pantone approved" means that the ink company has to get x-percentage of the Pantone book approved....not every color in the book!!!
Zelko probably still uses the ink shaker we had in Dover. They are awesome!

they only need to formulate 100 out of almost 3000. And even those do not have to be very close. That certification/approval is a JOKE!

Been using IMS 3 with Rutland C3, Zodiac Aquarius, and Union Mixopake/Maxopake for about 4 years now. Not every formula is spot-on, but I haven't had much trouble with adjusting the provided formulas to match Pantone. Before IMS, we grabbed formulas from the old Rutland Color Group website.

We really only use the standard formulas as a jumping-off point; once we get the color dialed in, we stick with our user formula and have consistent results across the various autos and manual presses in our shop. Haven't had to do too much adjusting of those user formulas after we get them Pantone matched, either, even across different batches of pigments. The consistency is huge for us because we have so many re-orders and frequently have short turnaround times that we need to meet.

And I agree with Zelko, that stirring the pigments is crucial for maintaining accurate mixes. We've got an M&R Turnabout that we use for mixing, and we stir manually with an ink knife to make sure everything is incorporated. We've got the attachments for stirring gallons and 5-gallons, but we don't use them very often.

still have the shaker.  but - the plastisizer that rises to the top of the pigment is so thin - when you put it in the shaker it finds its way out of the bucket
