9、ion 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 committe
10、e. 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
11、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 app
12、roval 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.

These test prints have a homogeneous distribution of ink
16、on a substrate, and a reproducible ink composition and relative ink coverage. Therefore, they are suitable for optical tests so that the measured reflectance can be assigned to a known ink coverage. If tests are done only for the characterization of mechanical and/or chemical properties of links, th
17、e user may apply less accurate methods. The methods described in this part of ISO 2834 are used in other International Standards, such as ISO 2846-3, ISO 2846-5 and ISO 2836. The preparation of test prints for paste inks (lithography) is described in ISO 2834-1 whilst screen inks will be covered in
18、ISO 2834-3. In ISO 2834-1, specific operational settings for the “round-to-round” and the “round-to-flat” offset ink printability testers are provided. Printability testers for liquid inks encompass a much wider array of operating processes and associated settings. In addition, it is generally ackno
19、wledged that it is not possible to directly determine the actual thickness of an ink film printed by gravure or flexography. Therefore, the guidelines included in this part of ISO 2834 are more general and will, of necessity, result in more opportunities for operator error when making the test print

21、tion of test prints Part 2: Liquid printing inks 1 Scope This part of ISO 2834 specifies a test method for preparation of test prints produced with liquid water-based or solvent-based printing inks as used in flexography and gravure printing. These test prints are intended primarily for optical test
22、s, such as colorimetry, transparency and reflection density as described in ISO 2846-3 and ISO 2846-5. They can also be used for testing gloss, light fastness and the chemical, physical and mechanical resistance to mechanical and chemical attack regarding either printing ink and/or substrate. Flexog
23、raphic inks with higher viscosity, such as those cured by radiation are also covered. This part of ISO 2834 is not applicable to inks for ink jet printing. 2 Normative references The following referenced documents are indispensable for the application of this document.
