Introduction
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 and file content, and finishing options. The degree to
which a reduction in productivity is experienced depends significantly on multiple parameters of the
job workflow. The most dominant of the parameters of the job workflow are: system environment,
application, and job characteristics such as the number of pages in a set to be printed, single-sided or
double-sided output pages, quality mode, number of print sets to be produced, substrate grammage/size
used, and finishing options, and job content complexities such as monochrome vs. colour, text/vector
vs. raster, page scaling and colour conversion. The existing International Standard (ISO/IEC 10561)
only addresses printing throughput for Class 1 and Class 2 printers and, therefore is not suitable for
comparing colour printing devices or high-speed page-oriented printing devices with many finishing
options and connectivity configurations.
This document provides a general method for measuring the productivity when the above-mentioned
job workflow parameters for digital printing devices are taken into consideration. This document also
includes a suite of test files, test-platform (hardware and software) setup 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.

INTERNATIONAL STANDARD ISO/IEC 24734:2021(E)
Information technology — Office equipment — Method for
measuring digital printing productivity
1 Scope
This document specifies a method for measuring the digital printing productivity of digital printing
devices with various office applications and print job characteristics. This document is applicable
to digital printing devices, including single-function and multi-function devices, regardless of print
technology (e.g. inkjet, laser). Devices can be equipped with a range of paper feed and finishing options
either directly connected to the computer system or via a network. It is intended to be used for black and
white (B&W) as well as colour digital printing devices. It 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. This document includes test files, test setup procedure, test runtime procedure, and the
reporting requirements for the digital printing productivity measurements.
This document is not intended to be used for devices which are not able to print on a media size of
A4/8,5”x11” or for devices which are not able to collate multiple copies of a print.
This document is not intended to replace manufacturer's rated speeds.

3.1
category test
test pertaining to one of two separate categories: office category, and advertising and graphics category
Note 1 to entry: The office category test is used to test and report first set out time (FSOT) (3.10), estimated
saturated throughput (ESAT) (3.7) and effective throughput (EFTP) (3.6) using content from typical office
applications and the advertising and graphics category test is used to test and report FSOT, ESAT and EFTP using
applications and files representing more complexity, higher coverage and a higher ratio of image and graphic
content such as pictures, gradients and embedded elements.

which may be achieved through either software features or via a hardware finishing device
EXAMPLE Repeating original order 1234, 1234, 1234, etc.
Note 1 to entry: Hard disk drive (HDD) is an example of a device feature that can be used to ensure proper output
order (3.19) by saving the images to disk then reading the saved pages to output in order.
3.3
default driver
printing device driver that is automatically selected as the default per the manufacturers’ installation
procedure
3.4
dual output order device
printing devices that support both original order output (3.18) and reverse order output (3.25)
3.5
duplex
duplex printing
two-sided printing
two-sided perfecting
printing where the printing device can make a number of prints with the printing being done to
both sides of the sheet
3.6
EFTP
effective throughput
rate at which a device produces pages measured from the initiation of the job through the complete exit
of the last page of the last test set (3.32)
Note 1 to entry: EFTP is expressed in images per minute (ipm) (3.13). EFTP can be affected by the digital processing
time of the test set as well as the run time of the test set.
3.7
ESAT
estimated saturated throughput
rate at which a device produces pages measured from the complete exit of the last page of the first test
set (3.32) through the complete exit of the last page of the last test set
Note 1 to entry: ESAT is expressed in images per minute (ipm) (3.13).
3.8
feature performance ratio
ratio of the device performance [such as first set out time (FSOT) (3.10) and estimated saturated
throughput (ESAT) (3.7)] with the subject feature ON versus the device default baseline performance
(without the subject feature ON)
3.9
feature performance test
optional test used to evaluate productivity changes with various printing and finishing
features enabled
Note 1 to entry: The feature performance test suite is run with default printing system settings to establish a
base line, and then with the selected feature (e.g. stapling) ON, for comparison.

3.10
FSOT
first set out time
number of seconds between the initiation of the job to the complete exit of the last page of the first test
set (3.32)
3.11
full detailed report
presentation of information including machine setup and full measured test results
Note 1 to entry: An example of a full detailed report is shown in Annex B.
3.12
full report
presentation of results including the first set out time (FSOT) (3.10), effective throughput (EFTP)
(3.6) and estimated saturated throughput (ESAT) (3.7) values for each file tested for a given category or
feature test as well as the calculated averages for the overall FSOT, EFTP and ESAT values
3.13
ipm
images per minute
printing rate, excluding time to first page printed, as measured when producing pages in a continuous
print mode for one minute with a single static document using a nominal grammage substrate
Note 1 to entry: Nominal printing speed is expressed in pages per minute or images per minute.
