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

Customer supply digital files.

We make digital proof and send to customer. If customer is not satisified with proof he do rework na supply own profs with our printing conditions, according ISO 12647-2:2013 Fogra PSO and BVDM

Proof must be valid and to have all elements required 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 dont know how is product prined before.

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

Some of few reason is

• uknown paper
• unknown ink
• uknown press linearisation

Also it's impossible to compare 10.000 printed book 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 immidiately see on press result.

Unortunatelly this is worst case. Ink during drying change his optical characteristic 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 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.

Typical Mistakes

How we see color is different topic but usualy we have several cases.

WYSYWIG

Wysywig or what you see is what you get is big myth in computer era.

Customer work on files and look on his monitor. Customer expect that what he see on his monitor printer must reproduce and if it's not it's printer fault.

There is several reason why you can't achieve same color reproduction on printing press as you see on your monitor. Mainly there is mistakes which fall in different categories.

Device fault

Cheap low quality monitor

Impromer monitor setup

Uncalibrated monitor

Software fault

Improper color setup in desktop application, typical mistake North America General Purpose 2

Invalid or legacy ICC profile selection, typical mistake SWOP Coated or Fogra 39 ICC Profile

Wrong softproof setup

Customer did not use softproof

Approvment of digital data in Email program

Usage of Acrobat Reader insted of Acrobat Pro

Software bug in desktop application.

Document elements

Usage of thin line instead of exact line weight

Usage of artifical Bold and Italic

Wrong colorspace space RGB instead of CMYK

Usage of 4 color in text C=50, M=50, Y=50, K=80

Usage CMY in text instead of K

Small size of text 8pt in negative

Gray color build with CMY, i must say sometime it works, but it's very hard to avoid variation during print run

Overprint white

Combine image and vector elements from different desktop application on same page. For example combine

gray color CMY=75,62,60 in Photoshop and put on background InDesign. Sometime works but sometime not.

Document format

Wrong image format, gif, png

Wrong image size, low resolution or too high image resolution

Wrong image color space, RGB instead of CMYK

Wrong document colorspace RGB instead of CMYK

Too high sum of inks, typical mistake is content with C=100, M=100, Y=100, K=100

Usage of Pantone C color library and product is printed on uncoated media.

Document exchange

Wrong PDF export setup, typical mistake is AdobePDF preset PressQuality
