Don't be a waster

The key to eliminating substrate waste is to understand the options available and the basic challenges associated with each product type - By Peter Kiddell
Published: 
09 April, 2010

Substrates are quite simply the surface that we print onto. Achieving perfect results is not as simple as it sounds however, because the range of substrates is constantly increasing.

From a printer’s perspective, generally the substrate is determined by the client. What the printer has to do is decide on the ink and drying/curing system that suits that particular substrate and its working environment. Assuming the substrate ink combination will provide suitable adhesion, the printer still has considerable responsibility in ensuring that the partnership remains satisfactory. Maintaining the condition of the ink and its drying technique is crucial, but so is managing the substrate.

Think before you ink

Some things in life are constant, including, it seems, the presence of ink. Despite its ubiquity, however, ink technology is constantly changing resulting in more choice for the print professional - By Peter Kiddell

Two major changes have influenced ink development in recent times: the abolition of heavy metal pigments such as lead, cadmium and chromium and the need to diminish solvent use. Both changes have been driven by the imperative to reduce Health and Safety and Environmental hazards.

Don't gamble with process control

Gambling is good for you if you are a supplier to the fruit machine industry, but printing on substrates that will be backlit necessitates a clean and accurate process. Perhaps that's no bad thing at a time when quality is the byword for survival - By Peter Kiddell

Display your individuality

So many products are totally dependant on brand recognition for their success - using innovative print techniques can provide the edge over competitors - By Peter Kiddell

Thank goodness we are all different in how we look, live, and run our businesses. There are times, of course, when replicating a look or product offering can be appealing and beneficial to our industry, but the power of product differentiation is also key.

Screen, an illuminating process

With the introduction of chip-and-pin payment cards the cry of ‘sign here please' is something we hear far less. Conversely, physical signs providing both instructions and information are on the rise day-by-day. We have the EU to thank for most of the growth - By Peter Kiddell

Somewhere in Brussels is a mole with contacts in the sign and print industry who is insisting on warning labels, posters and displays being produced for every conceivable human activity. These explain whether you can do it, can't do it or the consequences of same. Be aware that many of these will have to be specific colour matches and lightfast for seven years. So where do we turn to but screen printing where the inks we can use are more stable that those used of other processes.

A trip to India visiting graphics screen printing organisations revealed a host of sophisticated printing facilities. Fully air-conditioned and clean room environments were equipped with kit, inks and chemistry from Europe, US and Japan. The management were highly educated, with several having doctorates and CEOs determined to win the Best Place to Work competition for manufacturing companies.

Precision printing drives the digital revolution

Most electronic products rely on screen printing in their production. As circuits become smaller and the range of applications increases, so screen printing takes a stronger hold in the world of electronics production - by Peter Kiddell
Published: 
06 July, 2009

It is unfortunate that screen printing is sometimes overlooked when in fact most advanced technologies are dependent on the process. This dependency is at the core of advances in electronics. Printed circuit boards (PCBs) are largely produced using screen printing technology and as circuits have become smaller, and the range of applications increased, so screen printing has strengthened its position in electronics production.

Precision cures print problems

Stencil quality and drying and curing equipment both have a major impact on the accuracy of industrial screen printing. As ever, precision and consistency are key to achieving the desired result - by Peter Kiddell
Published: 
21 May, 2009

What makes screen printing so attractive to production process engineers is the ability to apply a controlled film thickness over large areas relatively quickly and yet with precise positioning. In the graphics industry the material printed is an ink with a coloured pigment or dye that that can be adhered to a range of substrates for visual effect. Being able to control the ink film thickness and the precise position and shape of the image is crucial to the final appearance.

Wage war on waste

Waste is the destroyer of profits, yet unfortunately it is often accepted as inevitable in the screen printing environment. Challenging this attitude requires guts, but it's a sure fire way to increase profitability - by Peter Kiddell
Published: 
05 May, 2009

One of the main reasons why screen printing is under pressure is that waste has become part of the culture. Waste can be defined as rejects, both on-line and off-line, unused materials, inefficient use of materials and consumables, wasted manpower, machine downtime and excessive set up time. Any reduction in waste goes straight to profits.

Finding hidden treasure

Printing is involved in every aspect of life. Not just printing on sheet materials, but in countless applications that we take for granted: speedometer dials in the car, mobile phone fascias and even electronic circuits and sensors. Here we take a look at the printing technology that makes these 'hidden' applications a reality - by Peter Kiddell
Published: 
09 April, 2009

THE CAR is in a treasure trove of printing applications. The speedometer dials, the indicator arms, the air conditioning controls, the windscreen, most of the front facia and the side windows all feature printing of some kind. Open the bonnet and printed electronic circuits are a major feature with dozens of printed sensors sending signals to help the suspension, for example, sense mistimed braking on a corner. Printing is present in almost every modern environment and it allows our technological world to operate.
