Grafična tehnologija - Vodenje procesa izdelave rastriranih barvnih izvlečkov, preskusnih in proizvodnih odtisov - 2. del: Procesi v ofsetnem tisku DODATEK 1

Dodatek 1:2010 k standardu SIST ISO 12647-2:2005         
Ta del ISO 12647 določa vrsto in vrednosti parametrov procesa, ki veljajo pri pripravi barvnih izvlečkov za štiribarvno ofsetno tiskanje ali pri proizvodnji štiribarvnih odtisov z eno od naslednjih metod: z rotacijskim tiskanjem, tiskanjem na pole, ali neprekinjenim tiskanjem ali s poskusnim tiskanjem za enega od teh procesov; ali z ofsetnim poskusnim tiskanjem za rastrirani globoki tisk. Parametri in vrednosti se izberejo glede na celoten proces, ki vključuje stopnje »barvne separacije«, »nastavitve filma«, »priprave oblike tiskanja«, »izdelave preskusnega odtisa«, »izdelave proizvodnih odtisov« in »površinske dodelave«. Ta del ISO 12647 – neposredno velja za procese poskusnega tiskanja in tiskanja, pri katerih se kot vhodni material uporabljajo filmi z barvnimi izvlečki; - neposredno velja za poskusno tiskanje in tiskanje iz obrazcev za tiskanje, ki nastanejo z metodami brez filma, če se ohranja neposredna analogija s sistemi proizvodnje filma; - velja za preskušanje in tiskanje z več kot štirimi procesnimi barvami, če se ohranja analogija s štiribarvnim tiskanjem, kot velja pri podatkih in projiciranju, za substrate za tisk in parametre tiskanja; - po analogiji velja za vrstične rastre in neperiodične rastre.

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.
Amendment 1 to ISO 12647-2:2004 was prepared by Technical Committee ISO/TC 130, Graphic technology.

Part 2:
Offset lithographic processes
AMENDMENT 1
Page 4, Subclause 4.2.4
Replace subclause 4.2.4 with the following text:
4.2.4 Screen angle (film or printing forme)
For half-tone dots without a principal axis, the nominal difference between the screen angles for cyan,
magenta and black shall be 30°, with the screen angle of yellow separated at 15° from another colour.
The screen angle of the dominant colour should be 45°.
For half-tone dots with a principal axis, the nominal difference between screen angles for cyan, magenta
and black shall be 60°, with the screen angle of yellow separated by 15° from another colour. The screen
angle of the dominant colour should be 45° or 135°.
NOTE See Note 2 in 4.2.3.
Page 4, Subclause 4.3.2.1
Replace subclause 4.3.2.1 and Table 1 with the following text:
4.3.2.1 Print substrate colour
The print substrate used for proofing should be identical to that of the production. If this is not possible,
the properties of the print substrate should be a close match to that of the production in terms of colour,
gloss, type of surface (coated, uncoated, super-calendered, etc.) and mass-per-area. Press proofing
should be carried out on the closest match selected from five typical paper surface types whose attributes
are listed in Table 1. For off-press proofing the print substrate should be selected to conform as closely as
possible to the attributes listed in Table 1 of the paper type representing the envisaged production paper.
The type of paper shall be stated.

Values in brackets pertain to measurement on the white backing specified by CGATS.5 and are given as additional
information.
For prints on papers whose surface properties are identical to those of paper types 1 to 5 but whose mass per area is
appreciably higher, the CIELAB colour coordinates given in parentheses should be used.
NOTE 1 In terms of gloss and colour, the paper types listed in Table 1 are representative of the range of print substrates used for the
processes covered in this part of ISO 12647, with the following exceptions:
⎯ the paper types 1 and 2 are not typical for web-fed magazine printing except for covers;
⎯ paper types 3 and 5 are not typical for four-colour business forms printing.
NOTE 2 If the final product is subjected to surface finishing, this might severely affect the print substrate colour. See also Note 2 in
4.3.2.2.
