Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12637-3 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This first edition cancels and replaces ISO 12637-5:2001, of which the terms and definitions have been
incorporated.
ISO 12637 consists of the following parts, under the general title Graphic technology — Vocabulary:
— Part 1: Fundamental terms
— Part 2: Prepress terms
— Part 3: Printing terms

Introduction
Documentation gives rise to numerous international exchanges of both intellectual and material nature. These
exchanges often become difficult, either because of the great variety of terms used in various fields or
languages to express the same concept, or because of the absence or the imprecision of useful concepts. To
avoid misunderstandings due to this situation and to facilitate such exchanges, it is advisable to select terms
to be used in various languages or in various countries to express the same concept and to establish
definitions providing satisfactory equivalents for the various terms in different languages. The purpose of this
part of ISO 12637 is to provide definitions that are rigorous, uncomplicated and which can be understood by
all concerned.
This part of ISO 12637 contains terms and definitions of printing technology and addresses printing systems
and processes.

68
inner frame dimension
〈screen printing〉 inner length and width of the area enclosed by the screen-printing frame, excluding all parts
firmly attached to the frame
69
keyless offset
inking mechanism of an offset press in which an ink metering roller is used instead of adjustment keys for
controlling the ink flow
70
laser printer
〈electrophotography〉 digital electrophotographic printer using a laser to form the image
71
laser thermal transfer
printing process employing a high-energy laser beam to transfer colorant from transfer layer to a substrate
with the use of physical and/or physicochemical phenomena such as sublimation
72
magnetic-brush developing device
〈electrophotography〉 device that transfers toner particles to charged areas of a photoconductor in dry toner
systems and some of magnetographic printing systems
73
magnetic printer
printer in which a magnetic print head transfers an image to a magnetized drum that picks up toner with the
opposite magnetic polarity and transfers it to the substrate to form the printed image when the drum is
demagnetized
74
make-ready
preparation process and operations in which adjustments are made to the press to ensure a satisfactory
printed image on the substrate
75
mass tone
colour of an ink in bulk which has sufficient thickness to hide the substrate colour such
