Standard Test Method for Volatile Content of Sheet-Fed and Coldset Web Offset Printing Inks

SIGNIFICANCE AND USE
4.1 This test method is the procedure of choice for determining volatile content of sheet-fed and coldset web offset inks. This information is useful to the ink manufacturer and user and to environmental interests as part of the determination of the mass of volatile organic compounds emitted from the ink.
Note 3: Since these inks do not contain water or any materials currently classified by US EPA as negligibly photochemically reactive (exempt solvents), volatile organic compound content is the same as volatile content. The volatile organic compounds in these inks are high boiling hydrocarbon oils which are, according to US EPA guidelines, 95 % retained in the printed substrate or oxidized into the ink film. Therefore, the mass of volatile organic compound emitted from the ink would be calculated as only 5 % of the volatile organic compound content of the ink as derived from the results of this test method.
SCOPE
1.1 This test method describes a procedure for determination of the weight percent volatile content of sheet-fed and coldset web offset printing inks. Test specimens are heated at 110 °C ± 1 °C for 60 min.
Note 1: Coldset web offset printing is often (also) referred to as non-heatset web offset printing.  
1.2 This test method is also applicable to sheet-fed and coldset web offset printing ink vehicles.
Note 2: Vehicle is the liquid portion of the printing ink. Any substance that is dissolved in the liquid portion of the ink is a part of the vehicle.  
1.3 This test method is not applicable to ultra-violet (UV) or electron beam cured materials, which must be cured by exposure to UV light or an electron beam as part of the test for volatile content.  
1.4 This test method is based on Test Method D2369, in which the allowable ranges are ±0.1 g for specimen weight and ±5 °C for oven temperature. Interlaboratory studies have shown that specimen weight and oven temperature must both be more tightly controlled in order to improve the precision of test results for sheet-fed and coldset web-offset inks. Such inks typically contain a wide range of high-boiling hydrocarbons and often have a volatile content below 25 %.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement see 7.5.1  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Evaluating Ink Stainblocking of Architectural Paint Systems by Visual Assessment

SIGNIFICANCE AND USE
5.1 This standard may be used by paint companies and raw material suppliers to assess effectiveness of interior architectural primers for blocking stains from bleeding through to a topcoat.  
5.2 In practice, different ink-stained substrates may give various results for stainblocking performance for a primer and topcoat system. As such, this test method may be used for a number of different ink-stained surfaces.
SCOPE
1.1 This standard provides a method for evaluating the ability of an architectural paint system to block ink stains from markers and writing instruments from bleeding through a primer into a topcoat.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Methods for Measurement of the Rotational Viscosity of Paints, Inks and Related Liquid Materials as a Function of Temperature

SIGNIFICANCE AND USE
5.1 The viscosity of paint, inks and many related liquid materials is dependent on temperature. It is useful to know the extent of this dependence. One use of such information is to prepare a viscosity-temperature table or curve. Then, if ambient conditions do not allow the measurement of viscosity at the exact temperature stated in a specification or regulation, the viscosity measured at ambient temperature can be used to determine the viscosity at the temperature of interest through the use of the previously prepared table or curve. Viscosity measurements that cover a range of shear rates as well as temperatures could include shear rates associated with paint application or allow extrapolation to such shear rates. This information would enable a producer or user to estimate the effect on application of heating the paint.
SCOPE
1.1 These test methods cover the use of rotational viscometers to determine the dependence of apparent viscosity of paints, inks and related liquid materials on temperature. The first method uses a standard rotational viscometer with concentric cylinder geometry running at a fixed rotational speed as the temperature is increased or decreased. The second method uses a rotational viscometer with cone and plate geometry running at a fixed rotational speed as the temperature is increased or decreased. The third method uses concentric cylinder or cone/plate geometry operated with a shear rate ramp at several discrete temperatures.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Methods for Measurement of Yield Stress of Paints, Inks and Related Liquid Materials

SIGNIFICANCE AND USE
5.1 The yield stress of a material is a measure of the amount of force required to initiate movement of that material in a pipe, through a pump, or from nozzle. The yield stress also characterizes the ability of the material to maintain particles in suspension. Along with viscosity measurements, yield stress measurements have been useful in establishing root causes of flow problems such as excessive orange peel and sagging and in explaining resistance to such problems. After a coating has been applied, flow and leveling tends to be inversely related to yield stress and sag resistance tends to be directly related to yield stress. The ability of an automotive basecoat to keep aluminum and/or mica flakes oriented has been related to yield stress (direct relationship).
SCOPE
1.1 These test methods cover three approaches for determining yield stress values of paints, inks and related liquid materials using rotational viscometers. The first method uses a rotational viscometer with coaxial cylinder, cone/plate, or plate/plate geometry. The second method uses a rheometer operating in controlled stress mode with similar geometries. The third method uses a viscometer with a vane spindle.  
1.2 A non-rotational technique, the falling needle viscometer (FNV), also can be used to measure yield stress values in paints, inks and related materials. See Test Methods D5478, Test Method D, Yield Stress Determination for details.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Fineness of Grind of Printing Inks By the NPIRI Grindometer

SIGNIFICANCE AND USE
5.1 Oversize particles in a printing ink may damage a printing plate, plug a cell, clog a nozzle and adversely affect the appearance of printed ink films. Fineness of grind measurements are useful for deciding when to stop the dispersion process and for determining if the test material meets specifications as agreed upon between the supplier and the customer.
SCOPE
1.1 This test method describes the procedure for determining the fineness of grind of printing inks using a NPIRI Grindometer. It evaluates the size of the largest particles in a finished dispersion but not average particle size or concentration of sizes.  
1.2 This test method covers both manual and automatic drawdowns using an A1 scraper.  
1.3 This test method is applicable to any dispersion that is fine enough to fall within the 0 to 25 μm range of the specified grind gauge. With a minor variation in procedure, it is applicable to both paste (nonvolatile) and liquid (volatile) inks.  
Note 1: The 0 to 25 μm gauge specified in this test method is similar in principle to the 0 to 100 μm Hegman gauge described in Test Method D1210 and the various gauges described in ISO 1524:2000. Sieve analysis for concentration of particles above 45 μm is covered in Test Method D2067.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Relative Mileage of News Ink on Newsprint

SIGNIFICANCE AND USE
5.1 Ink mileage on a production press is of economic importance of the user of printing inks, the lower the mileage figure, the less ink is required to produce a job. This test method provides a procedure by which news inks can be assessed for mileage or newsprint stocks for ink receptivity in the laboratory.  
5.2 Because of the many variables that exist among laboratory and production presses, this test method is apt to yield more meaningful information when results are expressed on a relative rather than an absolute basis.
SCOPE
1.1 This test method covers the laboratory procedure for determining the relative mileage of news inks on newsprint. The test method utilizes a proofing press, analytical balance and a reflection densitometer.  
1.2 This test method is intended for black oil-based news inks that dry by penetration (that is, letterpress or web offset) and for which a suitable reference standard is available. With appropriate optical instrumentation, it is also applicable to colored news inks.  
1.3 This test method may also be used to determine the relative ink receptivity of test newsprints versus a reference standard.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Drying Time of Oxidative-Drying Printing Inks by Squalene Resistance

SIGNIFICANCE AND USE
5.1 Inadequate setting or drying of sheetfed inks, or both, can cause blocking of stacked prints with subsequent loss of product. “Setting” of an ink refers to the rapid rise in viscosity of the printed ink film, sometimes accompanied by surface drying, that prevents transference of the undried ink film to adjacent surfaces under light pressure. “Setting” is a property of the ink-substrate combination. Inadequate drying may be due to several factors, but the primary causes are: (1) omission of metallic driers from the ink, improper ink formulation (2) unusual ink-substrate interactions, and (3) use of a fountain solution that is too acidic. If the test prints are made on a standard laboratory proof press, where there is no application of fountain solution, then only the first three possible causes can be evaluated. If the prints have been made on a commercial production printing press or some other acceptable means of introducing the fountain solution into the ink agreed upon, then the effect of fountain solution can be determined. It will often be necessary to run several tests to isolate the specific cause of a drying problem.  
5.2 This test method is suitable for most combinations of oxidative drying inks and substrates. Because this test method relies on a visual assessment of the extent of drying, very light colors and clear varnishes may present difficulties in quantifying the extent of drying. In such cases, the supplier and the customer should agree upon an alternative method of assessing the drying properties of the ink.
SCOPE
1.1 This test method covers the procedure for determining the drying time of oxidative-drying printing inks (also referred to as “sheetfed inks”) by squalene resistance of printed ink films.  
1.2 This test method is applicable to all paste inks that dry primarily by oxidation regardless of the substrate on which they are printed. With appropriate changes in the test fluid, it may also be used with paste inks that dry by other mechanisms, such as heatset or ultraviolet light.  
1.3 This test method utilizes a modified rub tester and is intended to serve as a “referee” procedure when laboratories, using less rigorous test procedures (see Appendix X1), cannot agree on their results.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Methods for Water Pickup of Lithographic Printing Inks and Vehicles in a Laboratory Mixer

SIGNIFICANCE AND USE
3.1 The lithographic printing process requires that some dampening solution be emulsified into the ink. These test methods provide a rapid means for determining water pickup under laboratory conditions. Test results may be useful for specification acceptance between the supplier and the customer.  
3.2 In order that results be comparable, the tests must be run at the same temperature and with the same type and quantity of liquid added prior to mixing.  
3.3 The emulsions obtained in these test methods are of larger particle size than those typically produced in printing nips. Because of these and other variables in the printing process, water pickup results do not by themselves predict lithographic printing performance.
SCOPE
1.1 These test methods cover two procedures for determining the amount of water picked up by lithographic printing inks in a laboratory mixer.  
1.2 Test Method A covers single-point water pickup; Test Method B covers the rate of water pickup. Both test methods are applicable to any printing ink and vehicle intended for the lithographic printing process.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practices for Preparation of Oil-Based Ink Resin Solutions

SIGNIFICANCE AND USE
5.1 These practices provide means of preparing small quantities of resin solution (in some procedures in an inert gas atmosphere using uniform, controlled heating).  
5.2 This practice provides quick ways to prepare a resin solution for quality control testing during the manufacture of resin solutions and vehicles. Samples can usually be prepared in approximately 30 to 45 minutes or less.  
5.3 These practices can be used to prepare commonly specified ink test solutions such as 33.3 % resin in alkali refined linseed oil, and 50 % resin in heat-set ink solvent (that is, C12 to C16 hydrocarbon petroleum distillate with initial boiling point (IBP) about 470°F).
SCOPE
1.1 These practices describe laboratory procedures for preparing an oil-based ink resin solution in a high-boiling solvent using four pieces of lab equipment:
(1) A hot oil bath (Sections 4 to 11),
(2) A stirrer/hot plate (Sections 12 to 16),
(3) An industrial blender (Sections 17 to 22), and
(4) A hot air gun (Sections 23 to 27).
ASTM Subcommittee D01.37 recommends using the hot oil bath procedure (Practice D5597) where possible.  
1.2 These practices use laboratory equipment generally available in a normal, well-equipped laboratory.  
1.3 One or several of these practices allows for rapid resin solution preparation (under 30 min, typical), can regulate the maximum temperature, can be done under an inert atmosphere, and can prevent the random solvent loss during preparation.  
1.4 These procedures are for use with ink resins intended mainly for oil-based offset and letterpress inks. The type of resins are typically, but not limited to C9 aromatic hydrocarbon resins, modified dicyclopentadiene resins, rosin pentaerythritol or glycerine esters, phenolic modified rosin esters, maleic anhydride modified rosin esters, and naturally occurring resins such as gilsonite.  
1.5 The typical high boiling solvents to be used include C12 to C16 petroleum distillates, 2,2,4 trimethyl 1,3-pentanediol di-isobutyrate,2 alkali refined linseed oil, tridecyl alcohol, or combinations of the above.  
1.6 To avoid fire or injury, or both, to the operator, these practices should not be used with low flash point solvents such as toluene or xylene. The minimum flash point of the solvents used should be 60°C (140°F) as determined by Test Method D56. (Warning—Users of this practice should be aware that the flash point of many solvents used for this test (as defined in Test Methods D56 and D1310) is exceeded in the heating cycle of this test method. Take safety precautions since there is the potential for vapor ignition. Do the methods outlined in a shielded exhaust hood, where there is access to a fire extinguisher if needed.)  
1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statement see 25.11.

Standard Practice for Preparing Prints of Paste Printing Inks by a Motor-Driven Printability Tester

SIGNIFICANCE AND USE
5.1 It is generally recognized that the best method for evaluating printing properties of ink-substrate combinations is by actual printing. this practice provides a convenient method for preparing repeatable laboratory prints at realistic conditions of printing speed, printing pressure and ink film thickness.  
5.2 This practice is useful for quality control, specification acceptance between producer and user, product development and research. Printed samples have found widespread applications for color matching, gloss-ink holdout and other appearance properties, permanency, abrasion, drying time and many other tests of interest to the printing ink, paper and allied industries.
SCOPE
1.1 This practice describes the procedure for preparing laboratory prints of paste printing inks using a motor-driven printability tester.  
1.2 This practice covers printability testers of four different designs, referred to as Tester A, B, C, and D. These testers feature “push-button” control of printing speed and pressure and facilitate measurement of exact ink film thickness.  
1.3 This practice is intended primarily for lithographic and letterpress inks that dry by oxidation or penetration. With appropriate drying or curing equipment, it is also applicable to other systems such as heat-set or energy curable.  
1.4 This practice is applicable to the preparation of single-color solid-area prints by dry offset (also know as letterset) or by letterpress on any flat surface including paper, paperboard, plastic film, textiles, and metal.  
1.5 The values stated in SI units are to be regarded as the standard. The only other unit of measurement used is fpm.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
