Hallo Liste, hallo XRite / Pantone
Meines Wissens schreibt eine Zertifizierung nach ISO 9001 vor, dass bei
der Lieferbeziehungen zweier Partner, die beide nach ISO 9001
zertifiziert sind, der Empfänger eines Produktes Einblick in das
Qualitätsdokumentation des Lieferanten bekommen muss.
Wenn ich als Druckerei, Vorstufe oder Print Buyer nach ISO 9001
zertifiziert bin und Pantone-Fächer nutze, verstände ich das so, dass
ich bei Pantone das Messprotokoll zur ausgelieferten Charge meines
Fäches anfordern kann.
Liege ich damit richtig ?
Gruß

Guten Morgen,
Leider hat die Antwort von meinen Kollegen Rachid Angri von PANTONE
krankheitsbedingt etwas verzögert. Eine generelle Aussage zum Thema
Farbabstand in den unterschiedlichen PANTONE Fächern können wir leider
nicht machen, da dieser je nach Druckfarbe und Papier sehr
unterschiedlich ausfallen kann. Wir geben aber gerne etwas mehr
Einblick in unseren Qualitätssicherungsprozess.
Unter _www.askpantone.com_ geben wir übrigens Auskunft zu vielen
häufig gestellten Fragen wie eben auch dieser:
*/_How much variance does Pantone allow for swatches when printing
books?
_/*
The specific tolerance standards that are used are proprietary.
However, so that you will better understand our process, I have
provided the following information.
In May of 2003, Pantone achieved ISO 9001-2000 Certification.
Following are some of our quality control procedures for all
PANTONE Color Publications, which can be found in our ISO
9001-2000 Standard Operating Procedures for Quality Assurance:
* Base inks are checked for shade and strength. Adjustments are
made until they match our standards to +/- 2% in strength and
almost no tolerance in shade. Hue difference, saturation
difference, lightness difference and total difference are
evaluated under D65 and at 10 Degree Observer using the CIE Lab
equation.
* A random sampling is made of stock from various skids of paper
and checked for uniformity of color and gloss.
* Base inks and certain blends are printed on a production press
to evaluate ink and stock. Color, gloss, quality of print, paper
picking, etc., are checked.
* During make-ready, color is matched to previous color approvals.
Stored wet ink density readings are used as a guide in evaluating
all printed colors. Before running, these matches are checked by a
Quality Control Supervisor.
* During production runs, every 200th sheet is pulled and checked
on a scanning densitometer. Tolerances are set at a +/-5%
deviation in density to the standard.
* Color approvals from the new production runs are measured on a
spectrophotometer and compared to our computer-stored PANTONE
Color Standards and previous production runs. Although the
spectrophotometric data is very useful as a tool for evaluation,
our final decision is always a visual color comparison.
* Printed sheets are cut, fanned out and inspected.
Recently, Pantone has taken the next step in achieving run
consistency, by installing a scanning spectrophotometer. We are
currently in the process of building a database of wet density
readings. We will be able to use this data to compare wet
densities to stored readings during the production run.
Please be assured that Pantone is committed to providing our
customers with products of the highest quality and we will
continue to make improvements to reduce color and print variations
in all PANTONE Publications.
Wir hoffen diese Erklärung beantwortet die Anfrage in ausreichendem Maße.
Mit freundlichen Grüßen
