= Quality =
Sometime is very hard to explain is it product printed well.

'''Quality becomes measurable, verifiable and reproducable!'''

Our quality control is based on industrial standard which is based on measurement.

Typical cases are mentioned below.

== Customer supply digital files ==
We make digital proofs and send them to the customer. If customer is not satisified with proofs he do rework and supply own proofs with our printing conditions, according [[https://www.iso.org/standard/57833.html|ISO 12647-2:2013]] [[https://www.fogra.org/en/fogra-standardization/standardization-pso/pso-e28093-the-process-standard-offset.html|Fogra PSO]] and [[https://www.bvdm-online.de/fileadmin/user_upload/bvdm_MediaStandard_Print_2018.pdf|BVDM]]

Proof must be valid and have all required elements [[https://www.iso.org/standard/66426.html|ISO 12647-7:2016]], Fogra PSO and BVDM.

 * Fogra MW 3
 * Job ticket
 * Measurement
 * Result in tolerances

In this case product will be printed according [[https://www.iso.org/standard/57833.html|ISO 12647-2:2013]]

== Customer Supply printed samples ==
We are happy to see your printed product, but we must warn you that we don't know how your product is printed before.

It's too optimistic to expect to make reprint of unknown printing condition.

Some of few reasons are

 * uknown paper
 * unknown ink
 * uknown press linearisation

Also it's impossible to compare 10.000 printed books with one sample.

During print run there is fluctuation, some of them are visible, some not.

In this case product will be printed according [[https://www.iso.org/standard/57833.html|ISO 12647-2:2013]]

== Customer approve on press ==
On first sight it's best sollution. Customer makes correction and immediately sees the results on press.

Unortunatelly this is worst case. The color during drying changes its optical characteristics and real color appereance is achieved after 2-3 days after printing. We can't speak anymore about quality and repeatibility.

After that nobody, even we can't do reprint of you product. In case of some mistakes in finishing, or different batches of ink's we can't repeat job.

In this case product will be printed according [[https://www.iso.org/standard/57833.html|ISO 12647-2:2013]]

= Lamination =
It's well known phenomenon that printed sheets change appereance after lamination. It's very hard to predict color changes.

Influnce of this changes is lamination thickness, vendor, batch, ink color, ink thickness, ink drying, ink batch, paper.
It's impossible to achieve 100% accuracy. Customer must to accept this variation.
Usualy because of diffuse effect with glossy lamination, intensive color appear darker.
With matt lamination we have oposite effect, intensive color appear lighter.
In this case unlaminated product will be printed according ISO 12647-2:2013 [[https://www.iso.org/standard/57833.html|ISO 12647-2:2013]]
