I have an idea, but would hesitate to say I understand them.

They are offset printing color standards. Gracol is more established (or better known) but not an ISO standard. Fogra is a newer competitive scheme. That’s about all I know.

I have posted regarding dot gain and such. I am in the process of trying the graycol to the best I can understand and I might add simplified it so it may not be close to the testing you have done. As I stated in a previous thread I shot fro what I think I read as getting my gray to print gray. My final dot gain goal on color ended up like this
K50% = 69% +/- 2%
C50% = 68% +/- 2%
M&Y50% = 62% +/- 2%

I got what apears to be a very clean printed piece. Not sure if this is the goal and I know I skipped alot of steps but what I am printing is definetly going to met my inhouse needs. I am waiting on a job from an outside vendor that is going to give me one of there fussy fussy jobs and see what I print using my current setup. I am by no means a Professional prepress guy and I think I would never say I was but what very little I know of prepress and the more that I know about printing and press I am printing better than I ever have on press. Thanks for the research you are doing and sharing

What is very important is the lab colours of the process solids - (how much ink u put down -) without that its hard to judge dot gain. You have to do it all
normally i would expect to see CMY dot gain the same. Yours match the US high dot gain and 68% ish

GRACol is a specification more than a standard. The new methodology that is being developed by the IDEAlliance group is called G7 and uses visual appearence of ink solids, grey balance and Neutral Print Density Curves to define the press run rather than traditional TVI values. The beta data for G7 is based on the FOGRA data because there is very little difference between the two. To learn more I would suggest visiting the GRACol website(www.gracol.org) and download the latest G7 'How To' v5.

We have not implemented the G7 methodology as of yet. We(Independent Printing Co.) have been following its developement closely and have been waiting for all issues to be resolved and we were hoping for ISO approval before we implement(interestingly we print very close to the specification now.) IDEAlliance is creating a registry of 'Master Printers' that we may want to become a part of. BTW-a new version of the 'How To' v6 has been posted
on the GRACol website.

Best regards,

The problem we have at the moment as printers is there are some out there who see this as an income stream - which costs us money .

I can definitely see where some may view this(G7) as a money making scheme vs. a better way to measure and calibrate a pressrun. I can say that I have been following Don Hutcheson's(GRACol Chair) methods and advice for the last four years and have not been dissatisfied with the results. Mr. Hutcheson has always been forthright and willing to help even though we are not a paying client of his. I feel his integrity is genuine, and he does believe this is a better way to print. I guess we shall see if the rest of the US(and the world for that matter) will agree. I will post when we have made our decision, and if we do become a 'Master Printer' the results.

Best regards,
TW
