Contract proofing provide a number of advantages for designers, advertising agencies, photographer or printer. First, you already know before production how the design is going to look, secondly, it prevents rejection of the print work and finally, it saves a lot of discussion about the colour quality of the final product of your client or printer.
- It saves time; a contract proof quickly gives a good image of your design.
- Saves money; making a printing test on a printing press is very expensive.
- A contract proof is leading, providing that the printer indicates to print according to that norm.
- Saves a lot of discussion because the colour test gives the right result.
Indeed, a colour test is essential for a predictable printing result.
Proofing Company makes contract proofing of every ISO norm or ICC profile. If the profile of your choice is not included in our list of contract proofing? Leave a message via our contact pageContacting Proofing Company or contact us directly via the WhatsApp chat on the site. We make sure we will add it to the list.
We make our colour tests on an Epson SureColor P7500 Spectro. This last generation Epson printer is equipped with a 12th colour (Violet), with which we go approach 99% of Pantone (PMS) colours (ironed material).
We work with certified substrates (with or without OBA (optical whiteners)) which also have a Fogra MediaWedge V3. After printing, it will be automatically measured with our inline spectral meter, and the result of the contract proof will be printed as a test, so you can always check, per contract proof, whether it is produced according the applicable tolerances.
Check measure ang equipment
To check our inline spectral meter, we regularly take samples with our Techkon SpectroDens meter to be sure that what is measured during the proof are the actual values!
“If only we had made a contract proof of that image”
ISO 12647 is a standard for the production of printed products. In basis, it has been developed by Fogra together with the Bundesverband Druck und Medien in Germany. The standard describes which measuring equipment must be used and under which circumstances files or printed matter must be produced.
Think about: LAB values for the colours, dot enlargement for grid fields, tolerances in Delta E (colour deviation), substrates, dot shapes, etc…
The objective of the ISO 12647 standard or other standards is to make the production process, which is divided over many departments, as efficient as possible and at the same time make sure that the end result has predictable colour qualities.
Customers place orders with various printers and media companies. The ISO standard makes sure that the same objectives are used for all printers and promotes interchangeability. There are different ICC Profiles and ISO standards available for every printing process. Think about sheet-fed offset, rotation, flexo, etc…
Will every print and every printer be the same?
No, that is not the case. The ISO standard is a tool with certain tolerances. The bandwidth of the tolerances makes sure the prints can still differ per printer. That is why it is so important to have a contract proof made. The contract proof is closest to the ISO standard and can be used as a guideline.
Every printer that works according an ISO standard, will be capable to meet the standards of the contract proof (within set tolerances).
This makes quality measurable, verifiable and reproducible!
