Differences between the Benchmark test, the P2P and Press Profile

 

In the last decade, our industry has achieved gigantic advances, going from being an artisanal work to becoming a complex and highly technical process. Which is why we always emphasize the importance of knowing the capabilities of your press and all the variables involved in the printing process.

The standardization of the printing process is done through a test system called Press Characterization. This process consists of 3 tests that, although they seem the same, are not. In this sense we will show you the order and the differences that exist between them:

1.- BENCHMARCK TEST: It is the first of the tests and its objective is to optimize the press, define the minimum point, the lines and isolated points both in positive and slide. Define minimum sizes of positive and inverted text and define the optimal speed of your press, among others. Typically a plate is made to print on all types of substrate (transparent and/or white) in cyan, magenta or black inks. In the case of transparent ones, a white background is added.

2.- P2P: Once the previous conditions have been established, we continue with this test to define the dot gain, gray balance and color overprinting, CMYK combinations of two, three and four colors in different percentages of color dots. It is necessary to make a cliché for each color that the press prints and they run together.

3.- PRESS PROFILE: The last, but not the least important. With this test we can extract the color space and determine the achievable color gamut that your press can reproduce, based on the defined conditions, creating an ICC Color Profile, to adjust the color testing system to the correct simulation response. regarding the final impression.  Like P2P, a cliché needs to be made for each color that the press prints and they are run together.

Important considerations:

1.- With the results of these tests, the press is profiled against the proofer (digital printer), with which the Certified Color Tests are carried out.

2.- The characterizations are individual and independent for each press. If you have several, even if they are the same model, you must characterize them separately.

3.- If you print on several substrates you must profile for each type.

4.- If after characterization you change any supplier or type of input (substrate, ink, sticky back or iron) you must repeat it, to ensure repeatability and consistency.

As you can see, although they have very significant differences, they are needed to timely address all the scenarios that arise and take advantage of the full potential of your presses.

At Grafiflex, we understand what it means to be a differentiator within the competition, to be at the forefront and to offer flexographic solutions to a trade as demanding as ours.

If you have not yet characterized, we invite you to do so. We have a qualified team to carry out these tests. We assure you that your printing process will be a before and after.
