Quality without compromises and full customer satisfaction are essential factors of our mission. Our corporate slogan “The Toner for Better Images” says what it means, positioning the company as a manufacturer, who has built a reputation on the quality and performance of products, customers can trust.
The premium brand strategy of INTEGRAL toner is for a large part vested in a focus on quality as well as consistency as key factors of customer satisfaction.
At INTEGRAL, we focus on what we can do best and what the name stands for: the development, production and distribution of premium copier and printer toners. This is why INTEGRAL pursues an uncompromising premium brand strategy.
Founded in 1966, INTEGRAL has become one of the world’s largest independent manufacturers of toner for copiers and laser printers.
Today INTEGRAL serves thousands of customers in all continents with an extensive range of imaging consumables.
INTEGRAL operates state of the art manufacturing facilities in Germany , Ireland and France. At our Research & Development Laboratory – research and quality control-personnel ensure that imaging materials from INTEGRAL always fulfil the most stringent requirements of our demanding customers.
At INTEGRAL we developed and manufactured our first toner in 1973. Since this time, significant investments have been made by INTEGRAL into some of the most modern and advanced manufacturing facilities, which can be found in the industry.
QUEST FOR LEADERSHIP
With significant investment in Research & Development, INTEGRAL ensures that all products released to the market meet the highest quality and performance standards. Qualified research staff are engaged in the development of new toner products with optimized performance for specific copier and printer systems.
INTEGRAL maintains a state of the art toner development and research laboratory. The research facility features highly sophisticated equipment used in the analysis and development of mono and dual-component toner formulations as well as for the scale-up and reverse engineering of copier and printer toners. Extensive testing of products is carried out at the research facility before being released to market.
In addition to Research & Development in toner, INTEGRAL co-develops and carries out rigorous testing of copier and printer parts and components in collaboration with some of the world’s leading part manufacturers.
R&D AND QUALITY CONTROL
Vital characteristics and parameters of toners are measured at INTEGRAL’s state of the art research and development facility by highly qualified personnel, engaged in the development and quality control of a wide range of mono and dual-component copier and printer toners. Parameter analysis includes the measurement of important properties such as: tribo charge, flowability, melting point, softening point, particle size distribution and magnetic properties amongst other important characteristics of the toners. Activities at the research laboratory include new product development, scale-up, raw material control and final product quality control.
QUALITY CONTROL BY R & D PERSONNEL
Each production lot of toner is carefully analyzed in the laboratory and copy or print testing takes place in the applicable printer or copier models.
ANALYTICAL & LABORATORY EQUIPMENT
Various parameters of toner and raw materials are checked by the use of specific analytical equipment. Various equipment used is shown below:
PARTICLE SIZE DISTRIBUTION
The size and distribution of toner particles is of critical importance to print yield and background levels. Specialised equipment such as the Coulter Multisizer is used to measure the particle size distribution of toners.
Coulter Counter Multisizer III
The system works by laser diffraction and is connected to a central unit. The sample is either introduced in suspension in a cell or is dispersed in a water-based solution, which circulates in the laser system. This equipment measures the particle size distribution.
Shimadzu Particle Size Analyser
The q/m Meter is used to measure the toner charge, which is the charge to mass ratio (q/m-value) of two component developers (toner/carrier mixture). It is used in the development of new toners as well as in quality control.
Epping q/m meter
GLASS TRANSITION TEMPERATURE AND MELTING POINT
This equipment measures the thermal transition of a material. In toner it determines the glass transition temperature (Tg) and the melting point (Tf) or (Tm)
MELT FLOW INDEX / EXTRUSION PLASTOMETER
This equipment measures the melt flow index (MFI) of toner powder. It is an indirect measurement of the viscosity of a product at a determined temperature. The more viscous the material the lower the MFI.

IR SPECTROMETER ANALYSIS
As an integrated part of R & D, target toner compositions are analyzed by means of IR spectrometer analysis.
Mattson Instruments Galaxy series FT-IR Spectrometer
Magnetic properties of mono-component toners and ferrite raw materials are measured.
DIALECTRIC CONSTANT DISSIPATION FACTOR
The LCR meter measures the electrical properties of a toner. Through this measurement it is possible to determine the dialectric constant and the dissipation factor. Such measurements provide an indication of the degree of dispersion of the different constituents of a toner.
Sieve towers are used to measure the flowability of toners. A given toner is passed through a number of consecutive sieves in the tower. The flowability of a toner is determined by measuring the passing time and quantity.

COPY AND PRINT IMAGE QUALITY TESTING
Before being released to the market all INTEGRAL toners are extensively tested in the intended copier or printer systems over extended periods. After having successfully passed these tests under various environmental and machine conditions, each product is subject to a prolonged field test on a broader base. The product is only launched after having successfully passed the field test.
COPIER AND PRINTER TEST LABORATORY
In addition to the parameters being measured on laboratory equipment, print and copy tests are run to determine a toners stability and performance as well as the matching of components

IMAGE QUALITY MEASUREMENTS
Densitometers are used to determine the image density of solid areas on print-outs and copies. Such measurements provide an unbiased recording of density related aspects of copy and print quality.
Environmental conditions such as temperature and humidity influence the characteristics and print performance of electro photographic systems and toners.
An environmental chamber simulates varying combinations of environmental conditions while print and copy testing takes place.
Temperature cabinets are used to determine the long-term impact of temperature on toners at a set temperature level.
Before entering full-scale production, new product manufacturing trials are run on pilot plant equipment. Full scale production takes place after meeting the necessary criteria
