Why, exactly, do you feel that uber-anal not to mention expensive calibration of every piece of gear in sight is 'worth it'?
Did the less than $10K [it must be close to $10K or you would have chosen another benchmark] you spent generate at least that much additional business? Why would anyone want to blow money of that magnitude on something that might be fun but is totally unnecessary? A color chart costs a couple of bucks, takes a couple of minutes, and seldom if ever, changes.
The printer and a color chart produced thereupon is the truth. A monitor momentarily matching, somewhat, the truth of the printer is frivolous and inherently undependable. It most certainly is not the truth, only a coincidental, tenuous, and temporary agreement with the truth. An allegedly profiled monitor is merely something else to go wrong. Do not complicate things unnecessarily.
Thanks for the reply, I think...
The cost is dependent on the shop setup. I for example had to calibrate 7 printers. 3 solvents, 1 flatbed, 2 aqueous printers, and 1 dye-sub. This cost a little under 10 grand.
If a shop has 1 printer it can cost as little as 2 grand.
So you ask why would one do this, instead of the faithful color chart technique, and also did it pay for itself once it was done.
First part of your question: the charts are good for certain projects, or when a calibrated system isn't working correctly (which is rare). What the charts are not good for is very specific colors. Many business have colors they are picky about and don't want to come to your shop and look through color charts etc... They will if you leave them no choice, but ask any customer and they would prefer not to. Now again, if you only had one printer to deal with maybe the customer wouldn't mind as much. Though, if their order is going to be using multiple machines and materials, color charts are simply inferior IMO.
Other advantage to custom calibration is the range of colors you will achieve, the trueness of grey scales will be better, and time managing orders and machines will be reduced.
I have already proven one can take multiple machines and produce near exact colors, which is mostly not realistic with using color charts. Can you imagine having to print banners, fabric, and posterboards for an order and having to look up charts for each machine, material etc... That is insane.
Without calibrated machines you simply can't rely on sending the print without pulling the charts out everytime, especially if the job is split between different machines.
Next, where are the savings and did I make my money back. Of course I did. I generally never have to worry about color. I generally never have to explain to new employees how to use a chart system. And customers don't have to waste time choosing a "best" match, cause the
sign shop is too lazy or cheap to calibrate their machines.
Obviously you can get by with charts, but there is something nice about being able to load prints and not have to pull charts everytime.
