Rigid Media Certification Process

The process

We have developed a convenient way of testing print media after printing with HP Latex inks, while collecting all necessary printing parameters. The HP Latex Certification program puts the material specifications and optimal setting for your rigid media straight into thousands of printers and into the HP Media Solutions Locator website.

1. Optical print quality check for coalescence, deformation, grain, banding, etc.

Optical checkWe test each media for obvious visual defects by printing carefully designed test files, designed to expose weaknesses in coating or surface materials. We are checking for issues like: banding, deformation, bleeding, marks on media, coalescence, and grain. By adjusting the printer settings and finding the right parameters within the bandwidths specified for the respective media, we will try to solve the visual defects.

2. Minimum color gamut required for certification
Each material category has predefined color gamut requirements. In other words: we expect a certain color range and quality for each media category. By creating an ICC profile and measuring the gamut volume of these profiles, we are able to determine whether the media capabilities fall within the required bandwidth.
3. Shrinkage

Latex ink requires curing, which has the potential to cause media to dimensionally shrink during the printing process. By printing specially designed test files and measuring the physical print after it has been fully cured, we make sure your material falls within the tolerances set by HP.

4. Water fastness
HP Latex inks are waterfast, under the right conditions and with the right material. This test is a basic water fastness test that ensures the media is capable of withstanding and handling water, within the expectations of HP and Color Concepts.
5. Ink cracking under tension
Printing on super flexible materials can be a challenge, especially when it comes to stretching and bending the material for its final application. HP Latex ink are designed for great flexibility. This test determines if a material in a particular category is able to handle the grade of flexibility you might expect from it. This test is done by stretching the material and detecting if any ink cracking occurs.
6. Ink adhesion

Ink adhesion is a crucial part of any printing process. HP Latex inks have great adhesion properties on compatible materials. This procedure uses industry standard tools to perform the required testing to make sure the materials are compatible with the HP Latex inks and provide the adhesion required for the application the material is designed for.

7. Wet / dry rub
Can I touch the material after printing? Does this media require lamination after printing? Just some questions every print shop wants answered. For this test we are using high-end lab equipment to simulate dry and wet rubbing as it might occur in daily life.
8. Scratchability

Every print shop and print media expert knows the test: you take a print, you have your thumb and you scratch. Since everyone is scratching different, we designed a reproducible test that simulates the average force of a reasonable amount of scratching that every printed material should survive.

9. Stackability

This test will evaluate if your material can be safely stored in piles. We will be checking if there is any ink transfer from your material with the standards set by HP.

Note that every thickness of your media needs to be tested in order for your media to be certified.
