hello,
I would like to know if a business making print out of documents and pictures (print shop) needs to calibrate its printers say after changing toners/carrying repairs or maintenance for the purpose of compliance to ISO 9001.
Note that the according to the manufacturer, the printers have inbuilt calibration/system.
thanks,
nidhir

I can't think of any circumstances under which calibration of a printer would be necessary or helpful. You might have to verify that printed documents are legible and properly scaled, but that's not calibration in the sense you're concerned about.

but how about the colour hue of pictures/graphics and so on

What are the documented requirements?

Good question. They do not have one. I will have to audit a print shop soon and they excluded calibration from their scope. So I wanted to make sure that it is justified and I would like to know what is the current practice in the business.

Does "print shop" mean that the business is doing things like offset printing, or is this just standard "electronic" printing (ink jet, laser, etc.)? I don't know much about printing presses and what might (or might not) need calibration. If the business has requirements for say, color matching, there could be a need to compare output to standards and perhaps make adjustments, which would be a form of calibration.

This may sound stupid: what is offset printing?

I have googled offset: No they do not carry offset printing . It is just xerox and so on...

Offset printing

Here's the deal: if the company does printing of any sort that involves matching the output to a standard and then adjusting the printer (or paper, or whatever) to achieve the required results (conformance with the standard), calibration is being done and should be properly documented.

Thank you for the wiki link as well as the 'deal'. It clarifies this calibration thing for me.
I will definitely dig into it.

You're welcome.

Along with that, I know that if printing barcodes there are national standards to ensure that a bar code printed in one place will be properly read in another.
ANSI X3.182-1990 goes into detail. Of course the "master" bar codes given to verify/ calibrate the bar code scanners are NIST traceable...
