The New Standard in Screen Perforation

Harkness' 4K Digital Perforation Pattern is now the industry standard perforation replacing the existing pattern for all Harkness Screen types.  The new pattern has been designed to enhance presentation quality for viewing audiences by tackling some of the key issues facing modern cinema projection setups.


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.

improved sound transmission

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.

The Digital Perforation Pattern has an open area of 4.1% and 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.
