предговор

ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у тој комисији. Међународне владине и невладине организације које су у вези са ИСО такође су укључене у овај посао. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електротехничке стандардизације.

The draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Објављивање као међународни стандард захтева одобрење најмање од стране 75% of member bodies.

Међународни стандард ИСО 12040 was developed by the Technical Committee ISO/TC 130, Graphic Technology.

Annex A to this standard is for reference only.

ИСО 12040-1997 Технологија штампе – Assessment of light resistance of prints and printing inks using filtered xenon arc lamps

увести
The methods described in this standard for evaluating light resistance using blue wool references are technically consistent with those given in ISO 2835. Међутим, according to the latter, natural light should be used to obtain a valid evaluation of light resistance. This standard describes accelerated test methods by specifying light sources and filters for daylight simulation and by exposing test samples to artificial sunlight.

Додатно, the international standard is partially consistent with ISO 105-B02. For more information on equipment and test methods, it is recommended to refer to ISO 105-B02.

1 домет
This standard specifies a method for assessing the light fastness of prints and printing inks by giving

– General test requirements for printed matter;

— Special testing requirements for inks.

This standard applies to all printing substrates such as paper, board, метал (sheet metal and sheet metal) and plastic film and all printing processes.

2 Normative references
The following standards contain provisions which, by reference, constitute the provisions of this International Standard. At the time of publication, the version shown is valid. All standards are subject to revision and parties to an agreement based on this international standard are encouraged to investigate the possibility of applying new versions of the following standards. IEC and ISO members maintain a register of international standards currently in force.

ИСО 12040-1997 Технологија штампе – Assessment of light resistance of prints and printing inks using filtered xenon arc lamps

3 Дефиниција
For the purposes of this standard, the following definitions apply.

3.1 Light resistance of printed matter to filtered xenon arc light

Printed matter is resistant to the effects of fixed light sources (filtered xenon arcs) and is not directly affected by the weather.

3.2 Light fastness of printing ink

To assess the resistance of standard printed matter according to the instructions for printed matter in this international Standard.
