Ink Testing Machines

Product Details:

Lloyds Laboratory Rub Resistance Tester is a tool for comparing the rubbing, scuffing and marking of inks and coatings on commercial print and packaging, it can be used as part of quality control in a production environment or an aid to development in the laboratory.
Modern papers and carton boards can prove a challenge for inks and coatings. Harsh substrates such as matt paper and recycled board are prone to marking, scuffing and rubbing during post print production and transportation.

The Rub Resistance Tester allows the user to compare the durability of printed cartons, commercial print or proofs of ink and varnish on a wide range of substrates. The tester uses a rotary motion to abrade the printed surface against virgin material, face to face against itself or to a reference material. The user can vary the abrasion force or number of cycles to adjust the severity of the test.

The washability and resistance to fat, oils and detergents of inks and coatings can also be tested. This tester allows the user to visually compare the performance of different batches of production, ink/varnish formulations or substrates under the same abrasive conditions

Features:

• Easy setup and configuration for fast test
• Programmable cycle to run test unsupervised
• Compact and Maintenance free design

Ink Flow Spreadometer are used to measure the comparative flow rates of liquids or paste over time. A very popular test in offset ink to evaluate the ink rheology and body with varied ink raw materials used. The spread meter is one of the methods for measuring fluidity of lithography and letterpress printing inks. This instrument is used to determine " spread " of ink. Test principle: a certain amount of ink is placed between two parallel plates, to deform the ink by the dead weight of the plates. Along with time elapsed, the ink spreads in a circular shape. With the increase of the circular area, the pressure applied on the ink decreases. After a certain length of time, the diameter of the spread ink is measured. Yield value is determined from the ink spreading speed.

Lloyds laboratory Rub Resistance Tester is a tool for comparing the rubbing, scuffing and marking of inks and coatings on commercial print and packaging. It can be used as a part of quality control in a production environment or an aid to development in the laboratory.

Modern papers and carton boards can prove a challenge for inks and coatings. Harsh substrates such as matt paper and recycled board are prone to marking, scuffing and rubbing during post print production and transportation.

The Ink Rub Resistance Tester is designed to determine the quality of adhesion, and scuff resistance of ink to paper surfaces, plastic and aluminium film. The motorised unit is simple to operate by entering the number of rubs in the preset counter and starting the unit. It will rub the sample until the pre-set value is achieved. Dry and Wet rub can beperformed on the Ink Rub Resistance Tester.

The method of operation is that a 2 or 4 Lb weight with a clean white board is swept across the test piece for a set number of times, then closely examined.

The washability and resistance to fat, oils and detergents of inks and coatings can also be tested. This tester allows the user to visually compare the performance of different batches of production, ink/varnish formulations or substrates under the same abrasive conditions.

Features:

• 2 in 1 unit for ASTM and BS test method
• Easy setup and configuration for fast test
• Programmable cycle to run test unsupervised

Lloyds research has developed the 3rd generation of Computerized Ink-O-Scope for the in-depth evaluation of your ink formulation and its dynamic behavior on press condition and making a sense of tack dynamically rather than just an arbitrary tack number.

Tack is not a static rheological property of an ink or vehicle. It depends on the formulation, applied dynamic conditions like temperatures, stress, speed and time. All these parameters may vary on printing presses, so it's important to know how strong several factors may influence the ink tack behaviors and in consequence the quality of ink under different practical conditions.

Tack dynamic behavior is used by ink makers and users to ensure the quality and consistency of the inks and its formulations. Because of the high repeatability and reproducibility of the tack results, lloyds ink-o-scope is an essential instrument used by many companies that operate on an international level with data exchange between various facilities to ensure homogeneous quality throughout the facilities.

Features:

• Design confirms to astm d 4361
• Very high accuracy and 100% reproducible results
• Ergonomically designed with easy cleaning.
• Negligible and minimal maintenance
• Individual display of all programmable test parameters
• Dedicated hi-speed electronics and
• Communication (data recording speed of 1000 readings per minute)
• Tackoware software (optional) for graphical online presentation, data interchange and comparisons of infinite results
• Easy diy digital calibration by simple deadweight method and not by varnishes or ink.
• Rubber rollers available for conventional or uv curing inks.

Product Details:

The Ink Water Emulsification Tester of the dampening solution to the ink surface on the plate and ink form rollers is inherent in the printing process and the major weakness of lithography.

 

If dampening solution, revolution by revolution, accumulates on the ink surfaces, it will interfere with and eventually prevent the critical ink transfer. This dampening solution can only be removed by emulsification into the ink. 

 

Therefore, lithography depends on the ink’s ability to emulsify the dampening solution which during the process, is unavoidably applied to the plate surface. The medium which is printed on the substrate is not the ink as was applied to the press but an emulsion of aqueous dampening solution in the continuous hydrophobic phase. 

 

Lloyds automatic Digital Ink water Emulsification tester produces accurate, repeatable water pickup test for lithographic materials and is the instrument specified in ASTM#D4942.

 

Lloyds Ink-Water Emulsification Tester Model 92 IWE is an automated programmable device employing a rotating set of mixer blade and a rotating ink sample beaker, ideally suited for water/fount-solution emulsification testing of printing ink and varnish for consistent performance on offset printing presses.

 

Features:

• Easy setup and configuration for fast test 
• Programmable cycle to run test unsupervised
• Compact and Maintenance free design
