Introducing a New Standard in Screen Perforation

The new Harkness Digital Perforation Pattern will become the standard perforation pattern for all screen types replacing the existing standard pattern. The new pattern has an open area of over 4% with over 65,000 holes per square metre. This helps to significantly increase light reflectance into cinema auditoriums compared to Harkness’ previous standard perforation pattern and provides a brighter and better quality viewing experience.

The smaller holes also allow for a closer viewing experience with less visible seams, while the increased quantity of perforations provides better sound attenuation.

Harkness’ 4K Digital Perforation Pattern has been specifically designed to reduce the onset of the Moiré effect. Moiré fringing is caused when the weave pattern of a screen aligns and then interferes with the projector’s pixelated images resulting in an undesired, strobe-like effect across the screen, which can have a huge impact on cinematic experience.

With the resolution of projectors growing, it is a common issue in contemporary digital imaging and the new perforation pattern helps to offset this.

 

Harkness' 4K Digital Perforation Pattern is now the industry standard perforation replacing the existing pattern for all Harkness Screen types.

Reduction of Moiré
The Digital Perforation Pattern is proven to significantly reduce the effect of Moiré, a common issue in contemporary cinema where 4K projectors are used. Moiré occurs as an unwanted strobe-like effect across screens, it is caused by the pixels in the projector naturally aligning with the perforation pattern on the screen.

Vertical and horizontal perforations are out of phase within the design of Harkness’ 4K pattern, reducing the probability of alignment.

Improved Sound Attenuation
Audio performance is noticeably improved with the use of Digital Perforation. The increased number of perforations improves sound transmission into auditoria, allowing amplification equipment to operate at a lower level and speakers utilised with ease at higher frequencies.

Brighter image
The Digital Perforation Pattern has an open area of 4.1% and over 65,000 holes per square meter, increased light reflectance into cinema auditoria provides a significantly brighter, high definition image.

Less Visible Perforations
The smaller hole size allows those sat closest to the screen to view a movie without their experience being compromised by visible perforations.
