How do we verify a printed sample and rate them?

[Yuvaraju.V.]

I understand that a good printing can be evaluated by print contrast.
Is there any thing more than this to quantify the print results and declare the superiority.
I have heard some print experts compare to print sheets and say sharpness, smoothness, image contrast etc., but I am not able to understand this because all these terminology are based on visual inspection. Is there any quantifiable method in evaluating the printed sample?
Kindly enlighten!!!

Printing is about reproducing supplied art. The art is represented by a contract proof. So the goal of the press work is therefore to reproduce the appearance of the proof. The closer the press work is to the proof then, in that sense, the better the quality of the printing.

There are many ways to quantifiably evaluate the printed sample.

One such method is System Brunner:
System Brunner AG

Another is Heidelberg's press image control:

To evaluate a printed piece one must first choose the attributes that are important to you, or your client. Knowing, and controlling, the expectations is the key.

What are the attributes YOU, the poster, consider to be important?
