print quality can offer you a small certification to certify that you are able to produce colour-accurate proofs in accordance with ISO 12647-7.
If you are interested, please contact us. We will promptly send you the test form to be proofed. You must comply with the tolerances that are measured in the ugra/Fogra Media Wedge CMYK V3. A properly displayed status line is also required.
This must contain at least:
- Label of proof system
- Colouring agent (which toner or which ink)
- Printing condition to be simulated (e.g. FOGRA39, i.e. offset printing in accordance with ISO 12647-2, PT 1/2, 60 grid)
- Colour management profiles
- Time and date of printing
The following tolerances must be adhered to under ISO 12647-7 or Premium PSO:
(Target value – proof)
|Substrate – paper white simulation||Max. ΔE= 3||Max. ΔE= 2,5|
|Average of all fields||Max. ΔE= 3||Max. ΔE= 2,5|
|Maximum of all fields||Max. ΔE= 6||Max. ΔE= 5|
|Maximum primary colours||Max. ΔE= 5||Max. ΔE= 4|
|Hue distance primary colours||Max. ΔH= 2,5||Max. ΔH= 2,2|
|Hue distance medium grey patches||Max. ΔH= 1,5||Max. ΔH= 1,3|
