Biosensors were previously defined as devices that respond to chemical species in biological samples or biological components. They are now described as analytical devices composed of a biological recognition element directly interfaced to a signal transducer, which together relate the concentration of a targeted analyze or analyses to a measureable response . The principle of a biosensor, therefore, is that a target molecule or a specific event is recognized by a biological molecule. The extent to which the target is recognized, it is detected by a transducer . Biosensors have achieved and continue to garner interest because of their many attractive features. These include high sensitivity, specificity, ease for integration with other devices, and portability for utilization at-point-of-use . Electrochemical sensors are widely used due to their simplicity, and miniaturization of the device is relatively easy. Moreover, the analysis is rapid, highly sensitive and is of relatively low cost. They have been widely application in many fields including food safety, green energy, bio-medical and environmental monitoring. One of the challenges that researchers are still striving to address, in all types of biosensors, is the application for real (often complex) samples on site.

In order to meet the needs for on-site analysis, it is necessary that we transition away from traditional, commonly used cumbersome beakers and electrochemical cell systems. Nanotechnology and exploitation of new fabrication techniques offer simple, smaller, but robust sensing systems perfectly suited for on-site analyses. Screen-printing technologies take an important part as tool needed to take electrochemical biosensors towards point-of-care. Our screen printing machine is using the technology for heat transfer labels, RFID labels, biosensor labels, etc. Although it has been in existence for over a thousand years, screen-printing technology has only been exploited in biosensors in the last two decades.

Screen-printing is one of the most promising approaches towards simple, rapid and economic production of biosensors. Disposable biosensors based on screen printed electrodes (SPEs) including microelectrodes and modified electrodes have led to new possibilities in the detection and quantization of bimolecular, pesticides, antigens, DNA, microorganisms and enzymes.

SPE-based sensors are in tune with the growing need for performing rapid and accurate in-situ analyses and for the development of portable devices.

Disposable screen-printed biosensors have been successfully employed in the development of analytical methods that respond to the growing need to perform rapid “in situ” analyses. Thus, the early detection of microorganisms, which plays an important role in the prevention of human health problems, animals and plants epidemics, has been carried out using this kind of devices. Moreover, microorganisms have been used as biological sensing elements in the development of sensitive microbial biosensors for the analysis of different analyses of interest.

Screen-printed disposable biosensors have been developed for the analysis of microorganisms such as Escherichia coli (E. coli), Salmonella, etc. In the same way, the incorporation of microorganisms in the SPE can be used for the analysis of different substances of analytical interest.

That is why we need to fully use of the screen-printing technology, which is a fast and cost-effective process, widely used in organic and printed electronics, and is one of the most promising technologies to produce electrochemical (bio)sensors for biomedical, agric-food and environmental applications . The advantages of screen-printed (bio)sensors include sensitivity, selectivity, possibility of mass-production and miniaturization, which facilitates the design of portable and cost effective measuring systems. Moreover, (bio)sensor fabrication through screen-printing technology is very versatile and this versatility is likely to underpin the progressive drive towards miniaturized, sensitive and portable devices, having already started to established its route from “lab-to-market” for a large number of sensors for both centralized and in-field analyses.

What factors will  influence the roll to roll screen printing speed ?

The roll to roll screen printing speed can be influenced by several factors. Some of these factors include:

• Printing length: The length of the print run can impact the speed of the printing process. The longer the print run, the longer it will take to complete the printing process.
• Design complexity: The complexity of the design being printed can also have an impact on the printing speed. More intricate designs may require slower printing speeds to ensure accurate placement and registration.
• Screen tension: The tension of the printing mesh can also have an impact on the speed of the printing process. Lower tension screens may require slower printing speeds to ensure even ink application.
• Printing machine speed: The speed of the printing machine itself can also impact the speed of the printing process. Faster machines can complete the printing process more quickly than slower machines.
• Material thickness and characteristics: The thickness, surface tension, and other characteristics of the material being printed on can impact the printing speed.
• Screen mesh count and tension: Higher mesh counts and tension can lead to slower printing speeds.
• Ink viscosity and flow rate: The viscosity and flow rate of the ink can affect the printing speed. High viscosity inks will print slower and require more pressure.
• Squeegee pressure and angle: The pressure and angle of the squeegee can influence the printing speed and quality.
• Printing machine type: Different printing machine types have different capabilities and may have limitations in printing speed.
• Operator skill and technique: The skill and technique of the operator can impact the printing speed and quality.

Nowadays, Most of the underwear, hats, jeans,shirts,skirts and dresses manufacturers take up the heat transfer label on their garments. We called they are professional manufacturers.

So why are they so popular in garment industry? Not only does heat transfer label label create a stylish design that is less intrusive than a fabric equivalent, but there are also savings in both cost and time to be made.

Heat transfer labels made process takes place in two parts. In the first stage, the design and text is printed on the transfer film or paper by silkscreen printing, the classic and conventional printing method on heat transfer label.

In the second stage, Through the heat press machine transfer to garments.

Roll to Roll Silkscreen Printing

Silkscreen printing uses a screen plate to transfer printing ink onto a substrate, one colour at a time. The areas that do not require printing are blocked out by stencil. The ink is applied through a squeegee which moves across the screen frame to fill the open areas of the mesh with ink.

There are two types of silk screen printing methods, sheet-fed silk screen printing and roll to roll silkscreen printing .

The downside of the sheet-fed silkscreen heat transfer label printing is that it can only print one colour at a time , requiring drying before the next colour can be applied. The printing speed is slow and most of are the semi-automatic configuration.This makes it perfect for one or two colour designs and little quantity production.

The advantage of the roll to roll silk screen printing is very suitable for multicolor images, mass production, and heat transfer label, electronic appliances, membrane switches, panel, soft circuit board, RFID label, IMD label, PCB label printing as well, called roll to roll silkscreen printing system, and it consist of a feeding unit, a screen printing unit and a hot air dryer.
