ACTEGA ACTDigi LEP Primer is Part of HP’s Expanded Primer Portfolio

ACTEGA launches its water-based ACTDigi® LEP Primer at Labelexpo Europe 2025, Sept.  16-19 in Barcelona, Spain. Developed in partnership with HP and included in HP’s newly expanded in-line primer portfolio, the ACTDigi LEP Primer ensures optimal print performance for different types of labels produced on a wide range of substrates, including coated and uncoated paper, synthetics and metalized substrates.

This performance is proven on even the most challenging structured substrates, such as velvety papers and wine labels.

ACTEGA’s ACTDigi LEP Primer enhances ink adhesion, enabling outstanding print quality. When combined with ACTEGA’s OPV solutions, including UV, LED, water-based, E-Beam, and solvent-based varnishes, it provides a versatile option for numerous substrates while boosting press performance.

The new ACTDigi primer also enables converters incorporate high-impact, visual effects, such as hot foil stamping, once the primer has been applied. Thanks to its excellent water resistance, ACTEGA’s new primer is ideal for applications requiring durability, like beer labels. It can also be applied before thermal transfer printing to create other highly durable, long-lasting applications.

Developed to Enhance Converter Operations, Products and Experience

The new ACTDigi primer is a collaborative result of ACTEGA’s rigorous R&D processes combined with HP’s exacting print standards. The primer has been developed to not only ensure the quality and value of the final PSL product but also with the converter experience at the forefront. The unique composition of the water-based primer extends the lifespan of critical press components, including the blanket and photopolymer printing plates.

ACTDigi LEP Primer eliminates common issues, such as foaming and yellowing, and minimizes ghost images, ensuring smooth production and consistent results.

ACTDigi LEP Primer also meets the highest regulatory standards. Compliant with the Swiss Ordinance and Nestlé’s stringent quality requirements and free from solvents, heavy metals, phthalates, and CMR substances, it is suitable for indirect food contact applications. Additionally, ACTEGA received the Cradle-to-Cradle material health certification for ACTDigi LEP Primer, further demonstrating ACTEGA’s commitment to sustainable and safe production practices.

“We are delighted to introduce the ACTDigi LEP Primer at this year’s Labelexpo Europe, a product born from our strong, long-standing partnership with HP,” says Dr. Thomas Sawitowski, SVP flexible packaging ACTEGA. “This launch marks a significant milestone for both HP and ACTEGA, reflecting our commitment to advancing print quality while delivering forward-thinking, flexible solutions that meet the evolving needs of the labels industry. Available in Europe this year, the ACTDigi LEP Primer will be available through our global distribution and service network in 2026.”

“Together we are introducing a primer that not only elevates print performance but also delivers the flexibility and reliability converters need to stay ahead in a dynamic market,” Regina Guslitzer-Okner, head of supplies, applications, and sustainability at HP Indigo, adds.
