BS ISO/IEC 24734:2021

What is ISO/IEC 24734 about?   

ISO/IEC 24734 specifies a method for measuring the digital printing productivity of digital printing devices with various office applications and print job characteristics.  

Devices can be equipped with a range of paper feed and finishing options either directly connected to the computer system or via a network.  

 ISO/IEC 24734 is intended to be used for black and white (B&W) as well as colour digital printing devices.   

ISO/IEC 24734 allows for the comparison of the productivity of machines operating in various available modes (simplex, duplex, size of substrates, etc.) and office applications when the test system environment, operating modes, and job mix for each machine are held identical.    

ISO/IEC 24734 includes test files, test setup procedure, test runtime procedure, and the reporting requirements for the digital printing productivity measurements.  

Note 1: BS ISO/IEC 24734 is not intended to be used for devices that are not able to print on a media size of A4/8,5” × 11” or for devices that are not able to collate multiple copies of a print. 

Note 2 BS ISO/IEC 24734is not intended to replace the manufacturer's rated speeds. 

Note 3: ISO/IEC 24734 is applicable to digital printing devices, including single-function and multi-function devices, regardless of print technology (e.g., inkjet, laser). 

Who is ISO/IEC 24734 for?  

 ISO/IEC 24734 on measuring digital printing productivity is useful for:  

• Printing device manufacturers 
• Personnel working in the printing industry 
• Printer servicemen 
• End consumers 

 Why should you use ISO/IEC 24734?   

 Many digital printing devices produce printed pages at a different rate than their nominal speed when running with different modes (simplex, duplex, print quality modes), different substrate grammage, system environments, applications, file content, and finishing options. The degree to which a reduction in productivity is experienced depends significantly on multiple parameters of the job workflow. 

ISO/IEC 24734 provides a general method for measuring productivity when the above-mentioned job workflow parameters for digital printing devices are taken into consideration.  

ISO/IEC 24734 also includes a suite of test files, test-platform (hardware and software) set up guidelines, and a procedure to be used for measuring digital printing productivity. It allows manufacturers and buyers of digital printing devices to describe the productivity of various digital printing devices with respect to representative office usage patterns. 

What’s changed since the last update?  

ISO/IEC 24734:2021 supersedes BS ISO/IEC 24734:2014, which is withdrawn. 

 The main changes compared to the previous edition are as follows: 

• Added a “Normative references” clause 
• “Terms and definitions” clause have been modified to add new definitions and removed definitions of terms not used in the text 
• Added a requirement that single copy output shall use the default “output order” setting and the alternate “order output” is an optional test 
• Added reporting of the “output order” setting as part of the summary and detailed reports since it has a direct impact on the ability for results to be repeatable 
• Added “ready delay time” requirement to “test measurement” procedures
