  • Profiling V/s standardization

    Hi,

    Many of people have concept that Profiling and standardization is same thing.

    Can you help me distinguish between this 2 concept.
    and also let me know the procedure for it.

    Please do the needful

    Profiling is taking a snapshop of an existing condition.
    Standardization is defining a target and a tolerance for deviation.

      It is very short and sweet answer....

      Can you give you explanation as you had given to my other question

        I don't understand your question. Can you restate it using different words?

          Dear Sir,

          Can you elaborate proofing concept and Standardization.

          It means what profiling exactly doing? how it give us snapshot of condition? What element include while profiling.

          My Sr. telling creating dot gain curve is profiling. But I dont think it include only TVI curve

            OK, this is my opinion. Others may disagree.

            I try to take an economic view of things.

            So, profiling and standards are related to economic impact.
            You can print however you want and tolerate any variation that occurs so long as there is no economic impact. If, for example, you're a magazine printer and your solid ink densities vary 30 points over or below industry standards or your registration is out by 1/8th inch - that's OK as long as your advertisers don't complain and ask for a discount, or charge back, on their ads. If they complain then there is a cost. If there is a cost for failure to comply then there is a reason to define a standard (target) and tolerance for deviation.
            For example, I was at a newspaper printer today and one of their car advertisers complained about the misregistration of their ad making the cars they were advertising look bad. The cost to the newspaper publisher making good on that complaint is $1600. If that problem occurs 10 times then that's $16,000 in costs (or reduced profitability) to the newspaper. That cost might be a good enough reason to the newspaper to establish a standard target and tolerance for misregistration. Why? Because failure results in costs and reduced profitability.
            If, to use your example, dot gain variation results in increased production costs or reduced profitability then it would be a metric that you would apply a target and tolerance for deviation to. If it doesn't result in increased production costs or reduced profitability then you can ignore it.
            In my experience, data based on cost and profitability is the only thing that convinces management to invest in making changes to the production process.

                Standardization = getting repeatable results. The results don't have to be accurate. The important part is that they are consistent and reproducible. On a digital printer or plate setter, this could be running a calibration process recommended by the manufacturer.

                Profiling = Once you have predictable results, you take it a step further to have accurate results. This is where profiling comes into play. You output a file with known values and use a measuring device to compare the original versus the output results. Software then creates a profile which helps you helps map the colors so the output is a more accurate match to the source.

                (That's the short version)

                  Hi Greg. I would personally characterize your description as fingerprinting rather than standardization. Where there is a standard, as Gordo pointed out, there is typically a target to aim toward, and tolerances for deviation as specified by a standardization body (ISO for instance). So accuracy may matter. Fingerprinting may or may not involve aiming towards a standard. However, I don't think adding "fingerprinting" is going to lessen the confusion of the OP.

                    I think I went off on a tangent. I had just returned from a newspaper publisher where everything was done by eye and there were no standards. I was trying to give them the tools they needed to rationalize the investment into getting the right tools to management.

                    Apologies. gordo

                      Hi Meddington

                      I assumed the OP meant fingerprinting/characterizing a press since it was coupled with profiling. If pacificiam said "printing to a standard", I would agree with Gordo's explanation. I just re-read the OP and I'm not really sure what pacificiam meant.

                      Good points in your post. Thanks for commenting.

                        Well what I'd say is that profiling is the process of characterizing printing devices. Since there are so many devices printing on so many media under so many different conditions, if you want to determine exactly how a device prints, and how to prepare files to send to it, you must have a characterization of how it prints in the condition in which you intend to use it.

                        That's a profile.

                        And profiles are a first necessary step to standardization.

                        Because what standardization does is attempt to make some group of disparate printing conditions print the same. Or in other words: Once you have a group of devices profiled, then you create a workflow in which you define one of those profiles as a target condition, and then tell all the other devices to match it.

                          But standardization can be accomplished completely without profiles. In fact, the characterization data used to create "standard" profiles comes from press runs compliant with a printing standard. Typically in a proofing scenario, profiles (of the ICC variety) would be required, but not always.

                            I usually explain that standardisation is to align a machine/process to a standard so that printed results will be similar in different print plants.

                            Profiling is what a printer does for the individual press.

                            to simplify (Safe CMYK workflow):
                            If only profiling a press RGB images are usually colour managed, but CMYK values will differ, each printer goes as far as it can to reproduce the original. Using a standard would bring even CMYK values closer together since we are defining ONE target.
