Delivering superior optics and lighting for highest quality printing

Optics for Prepress Applications

In printing and publishing, prepress is what occurs between the creation of a print layout and the final printing, including the manufacture of a printing plate.  Excelitas enhances product performance with a complete range of standard and customer-specific optical solutions for printing plate production, inspection and quality assurance that deliver consistent, high-quality lenses with superior imaging accuracy. Our cutting-edge technology creates illumination and imaging optics for a range of printing needs:

• Imaging systems
• Exposure systems for offset, screen, flexo and gravure printing
• Laser writing on both thermal and UV sensitive plates
• Digital imaging for computer-to-plate (CtP), computer-to-film (CtF), computer-to-conventional-plate (CtcP)
• Job printing, newspapers, security printing, digital printing, packaging printing
• Engraving with high-powered lasers
• Internal drum, external drum and flatbed exposure
• F-Theta lenses, fiber head, full-field imaging
• Laser optics, laser modules, standard components, electro optics and drivers
• Web inspection, registration, color management, quality monitoring

Reprographic Lighting

For graphic reproduction through mechanical or electrical means such as photography or xerography, Excelitas lighting leads the way for applications including catalogs and archives, as well as in the architectural, engineering, and construction. For over 40 years, Excelitas has been a leader in supplying Xenon flash tubes and trigger coils for reprographic lighting needs. Our Xenon flash lamp technology is well-suited to toner fusing and exposure requirements for high-volume printing and copying jobs.

Xenon flash tubes have the highest peak luminance of all light sources. Excelitas offers flash lamps for the printing/reprographics industry, going up to energies of 2,000 Watts. We bring together an impressive complement of technical expertise, high-volume manufacturing and localized support to meet the growing demands of reprographic lighting.

Infrared Emitters and Systems for Printing Ink Drying

Printing is used on a wide range of materials, from napkins printed with flexography to brochures and advertising materials produced with offset or screen printing. In digital printing, ink must dry quickly to keep pace with the printing process. This is especially important for water-based inks, where effective drying helps high-speed printheads operate at full capacity.

Excelitas' Noblelight Carbon Infrared Systems (CIR®) support efficient drying for water-based inks. Our Infradry® systems combine infrared radiation and air management to improve drying performance. Hybrid infrared emitters dry both the surface and interior of materials such as cardboard and napkins.

Advantages of Infrared Heat for Printing Ink Drying

• Contact-free energy transfer
• Low maintenance requirements
• Infrared emitters precisely matched to the product
• Optimal wavelength selection to accelerate drying and increase energy efficiency

Excelitas offers IR drying solutions spanning NIR to medium-wave carbon infrared. By utilizing IR emitters precisely matched to the ink and material, these solutions help improve drying performance and increase energy efficiency.

UV LED Curing for Printing Applications

Excelitas UV LED Curing Systems are poised to take on the next generation in UV LED printer solutions for digital inkjet, flexographic, and screen-printing applications. UV LED curing can improve print quality with less heat impact to the substrate, and lower operating costs through extended life and less frequent maintenance intervals. At the same time, the use of UV LED further enhances the environmentally friendly aspects of UV printing with dramatically lower energy consumption and no mercury content or ozone emission.

Our extensive portfolio of UV LED curing products comes in a variety of sizes to match your needs for a wide range of applications to support high printing speeds without compromising print quality.

• Digital inkjet for bi-directional, single-pass, and 3D printing to create products such as posters, labels, signage, packaging, and 3D objects.
• Flexographic printing for labels and packaging applications. The low heat output enables new capabilities such as heat-sensitive materials, unsupported films, and thinner substrates while requiring less maintenance and energy.
• Screen printing on various materials, including plastics, metals, ceramics, glass, wood, and posters. UV LED for screen printing is used for direct bottle and tube decoration, which eliminates the need for a label.
