We manufacture Inks for different pritning and packaging industry

Production Capacity:

With the advanced machinary and optimising operating performance we are able to manufacture more than 1000 Ton of Ink per Year.

Viscosity Testing

Viscosity is a measure of a liquid’s ability to resist flow. A thick liquid that does not flow easily has high-viscosity; a thin liquid that readily flows has low-viscosity. The viscosity of ink strongly affects how it behaves on the press and is ultimately transferred to the sheet.

Liquids such as printing inks have thixotropic qualities. Inks are highly viscous under normal conditions, but will gradually become less viscous as force or stress is applied. To illustrate this phenomenon, consider what happens to an ink over the course of an average press run. Before it is removed from the can, an offset ink behaves more like a semi-solid than a liquid. However, as the press’ rollers work the ink, it becomes less viscous and more fluid in state. We can clearly see that as the ink is subjected to force, it becomes less viscous. This can negatively impact print quality, as low-viscosity inks are less capable of reproducing sharp halftone dots.

Fluctuations in temperature can have a drastic impact on the viscosity of ink. For example, a temperature increase of 5.5°C can reduce the viscosity of a printing ink by 50 percent or more. This strong correlation between temperature and ink viscosity can have serious implications. Colour changes on paper can occur over the course of a press run if the ink is not at its optimum temperature. Similar colour variations can occur between printing units if temperature is not kept stable.

The viscosity of ink characterizes multiple aspects of how well the ink will transfer onto its substrate, thus affecting the quality of the printed image. Throughout a press run, the properties of the ink’s viscosity can have several effects, on ink absorption, colour strength and drying. Highly viscous inks can be problematic as a result from the amount of tackiness it has; higher ink tack causes difficult image transfer to the substrate. With low viscosity, inks become more mobile and tend to flow on the printed substrate; this will often result in issues such as a growth in size of halftone dots, which causes the image to lose its sharpness and dirty printing.

Thus our each production batch is subjected to test viscosity by two methods

a. B4 cup

b. Brook field Viscometer

Fineness Of Grinding

Also called grind gages and Hegman gages. Many types of solid materials must be ground or milled into finer particles for dispersion in appropriate liquid vehicles. The physical properties of the resulting dispersions, often called “grinds”, depend not only on the actual size of the individual particles, but also on the degree to which they are dispersed.

The Fineness of Grind Gage is used to indicate the fineness of grind or the presence of coarse particles or agglomerates in a dispersion. It does not determine particle size or particle size distribution.

Fine grinding improves printability of the ink and improving the ink mileage and thereby reducing the printing and packaging cost.

Thus we ensure that the pigments are grinded to the desire particle there by increasing the performance of the ink. Our each batch of ink is tested for its grinding level then subjected to further testing.

Gloss Of Ink

The gloss of an ink is its measure of its ability to reflect incident light and depends to a large extent on whether or not the ink forms a smooth film on the surface of the substrate and masks any irregularities. The degree of gloss depends on multiple factors like nature of colorant, its particle size, shape and surface characteristics and the amount of resin and its ability to form a continuous film.

At Dilip Industries we ensure that the ink manufactured by us provides the desired gloss after printing. Our facility to test the gloss of the ink before it is dispacth to the clients ensure that we supply desired quility of ink and maintain the consistance of the ink.

Rub Resistance / Tape Resistance

Different packaging and pritning industry has diffrent requirements as per the use case and end  applications. However rub resistance is very important property of the ink when in comes to pritning and packaging industry. Most of the verticles require ink to be external rub resistant and tape resitant. Abrasion resistance is a desirable and sometimes critical property of printed materials.

Abrasion damage can occur during shipment, storage, handling and end-use. The result is a significant decrease in product appearance and legibility of product information. The amount of abrasion damage to a printed surface is dependent shipping conditions, possible temperature and humidity, time and many other variables. Prior to dispatch of ink we test for the rub and tape resistance.

Draw Down / Pull Down

A means of evaluating the color mixing of a printing ink by depositing a layer of the mixed ink on the surface of a substrate using a smooth-edged knife. Drawdown is one of three basic tests used to determine the accuracy of color matching and mixing processes, the compatibility of the various inks combined, the performance of the ink on the substrate, and the drying characteristics of the ink.

The basic test we perform after every batch to ensure ink consistence is achieved upto the desired level. The drawdown on the substrate on which print need to be taken helps us identify any issues there by improving the sucess rate of the ink to run on machines and substrates.
