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 ISO 12647-2:2013 Fogra PSO and BVDM
Proof must be valid and have all required elements 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 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 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.
