Contract Proofs

[lostboyz]

I have a question, if we have a contract proof created in one place then it will be sent to another place for color matching is it still accurate? like for example from Philippines to Australia. Considering the environment?


Thanks,

I would hazard a guess that there are too many unknowns.

Add a colour bar when the proof is produced. Measure the colour bar and provide a report and or measurement data in a .txt file.

After the proof is received, measure the colour bar and compare to the original measurements (factoring in minor statistical variances between similar but different spectro hardware).

Thanks for the quick reply!
is the mediawedge will do?

Just to be clear....when you say: "we have a contract proof created in one place then it will be sent to another place for color matching" that you mean this other place will be matching the contract proof you sent by matching their proof to yours?

Or do you mean that the other place will be going on press and matching the colors of the proof that you've sent them?

Considering matching on the press.

Yes, a standard Ugra/Fogra v3 ISO12647-7 media wedge/colour bar (or perhaps IDEAlliance in North America).

Is the end printer “happy” being held to another’s proof?

Do they have a successful history of being able to “match” an externally produced proof?

Is the proof produced/certified to an industry standard such as Fogra 39 / ISO Coated v2?

Hello Stephen,

"Yes, a standard Ugra/Fogra v3 ISO12647-7 media wedge/colour bar (or perhaps IDEAlliance in North America)."
- yes, Ugra/Fogra v3 ISO12647-7 media wedge

"Is the end printer “happy” being held to another’s proof?
Do they have a successful history of being able to “match” an externally produced proof?"
- actually this is the first time that i will do this

"Is the proof produced/certified to an industry standard such as Fogra 39 / ISO Coated v2?"
- the proof is pass based on the Ugra/Fogra standard (ISO12467-7)

Thanks,

That's important and makes a difference.

Methinks you need to have a handshake. I.e. Have them make a proof that they consider their contract proof from your file and compare their proof to yours. (This is in addition to Stephen's suggestions)
If their proof matches yours - you're golden.

What is the printer’s stance? Are they confident? Neutral? Pessimistic?

”Is the proof produced/certified to an industry standard such as Fogra 39 / ISO Coated v2?”
- the proof is pass based on the Ugra/Fogra standard (ISO12467-7)

Thanks,

Great, the target is an ISO specification (I presume ISO Coated v2/Fogra39).

Does the printer say that they can actually print to the same specification as the proof is targeting?

Thanks Gordo,
"Have them make a proof that they consider their contract proof from your file and compare their proof to yours. "
- nice suggestion, I'll ask them to do this!


Thanks Stephen,
"Does the printer say that they can actually print to the same specification as the proof is targeting?"
- I'll ask them if they can print as my target proof.


Thanks all for a very nice and informative replies!

We (as a printer) are happy to accept an external proof as long as the proof is according to Fogra39 or Fogra47, since these are the Fogra standards that we print.

Our biggest issue would be that the customer wants to print on a paper that doesn't match the white point of these standards. We usually talk to the customer about this before printing.

My two cents,

I.e. every paper?
The paper that we print on has a white point that is more or less (mostly more) off the white point of FOGRA39/47. My favourite in that regard is some uncoated paper with b=-14.

If we receive external proofs, we often create our own proofs and see if they match.
More often than not they do not match. Be it that the source files have changed before we got them or something else.
Best thing for that: a proof of all pictures in a brochure; most pictures have red, hand-written text beside it that says "more magenta", "less green" and so forth. Totally viable to use that proof to match on press.
