What are digital hard-copy proofs?
They are digital printouts on a standard inject printer, which is regularly calibrated, so that it can print with high colour accuracy (almost 100%).
What are certified digital hard-copy proofs for?
In the case of offset printing, colour performance depends on various factors, like whether the file has been properly exported (colour profile), the condition of the machine, the printing-paper type, the ink quality, the machine operator…
The use of digital proofs can ensure the quality of the project. Based on a certified digital hard-copy proof, offset operators can check the output colour quality. They can compare the output material with the hard-copy proof they have. Digital proofs are much less costly (10-15euro for each A4 page) and can help you avoid many mistakes.
In order to create a proper hard-copy proof for each project, following requirements must be met:
- First of all, the file must come in the correct format. (view previous posts)

- Thirdly, the company you’ll choose to generate your hard-copy proofs must be able to provide certified proofs. More on a previous post. http://offsetvsgraphicdesign.blogspot.gr/2012/03/blog-post.html
Certified digital hard-copy proofs facilitate colour accuracy while at the same time they don’t cost much. You should get at least one for each project.
