UV Curing Inks and its advantages

A variety of inks are used in the label printing industry today. Few examples are ink/water balance, fountain solutions, heat-set, cold-set and energy curable inks. UV cured ink is a completely solid system that is dried using photochemical processes.  Inks that are made from fluid polymers and monomers are exposed to high intensity ultraviolet light in a reactor. The exposure to UV light releases the free radicals and causes polymerization of the substance and a dry ink film containing the pigment is left behind. The applications of UV cured inks go beyond printed labels. These inks are used in electronics, automobile glass and plastic decorations and many more areas. Labels Manufacturers in India have been using UV cured inks in speciality printing like liquid cartons, flexographic printing and cosmetic packaging.

The advantages of UV cured inks

The first advantage of these inks is that they are very easy to handle, for the simple reason that the ink is completely dry. The dry ink has many advantages like trouble free operation in the printing machine and there is no threat of ink clogging. The UV ink also does not dry on screen and this makes it possible for printers to run for extended periods of time and achieve very high production throughput.

Absence of any volatile organic compounds (VOCs) makes the ink more environmentally friendly as well. When compared to heat-set inks, the UV cured inks have no toxic solvents and thus no gaseous emissions.

The colour value of the UV inks is also excellent. Most UV inks range from being transparent to translucent. This higher degree of transparency in inks translates to a very clean colour gamut. This makes such inks perfect for processes requiring four or more colour processes graphic printing.

These advantages of UV inks especially enable printing of sophisticated and highly detailed bottle labels and self adhesive labels. UV inks are a blessing to Label Manufacturers allowing them to print high quality tags in larger numbers within shorter periods of time.

Thermal Direct Printing and its applications

Thermal Direct Printing is a form of printing that makes use of chemically treated substrate and applies heat (thermal energy) to it for printing something. The chemically treated substrate is called thermal paper. When the paper is fed into the thermal printer and heat is applied to different areas, those areas turn black to produce an image. Thermal direct printing is the only form of printing that involves no ink or toner.

Uses of Direct Thermal Printing

Label manufacturers have found direct thermal printing suitable for a variety of printed labels. The simplicity and the affordability of the entire process is what make direct thermal printing ideal for select types of adhesive labels. Direct Thermal Printing does not require any ink or toner. It just needs a thermal paper which is not very expensive as compared to other substrates. The direct thermal printers are also inexpensive by themselves. They are not very big in size and not too complicated either. The typical components of a thermal printer are: a thermal head where heat is applied to the paper, a spring that applies pressure to the thermal head, a platen that feeds the paper and controller boards. Label manufacturers in Mumbai use it to print bar codes, FM CG package labels and simple labels to be used in shipping.

What is Flexographic Printing?

Flexographic printing or flexography is a process that utilizes a flexible relief plate in the printer. These plates are often made of rubber or plastic. Label manufacturers use flexographic printing for printing labels on plastic, foil, paper, metallic films and other forms of substrates used in packaging industry. Among other types of substrates, flexography is primarily used to produce printed labels on non-porous substrates like plastic used in food packaging. This is why flexographic printing is synonymous with plastic printing.

The Flexographic printing process

The flexographic printing process involves the substrate being fed into the printer in roll form. The substrate then moves through different print units that only prints a single colour. The various tones and shades of colours are achieved through processes similar to that in lithographic printers where the basic shades of ink- magenta, cyan, yellow and black are overlaid.

Four basic operations are involved in a flexographic printing process: image preparation, plate-making, printing and finishing. Image preparation is where an electronic copy of the art is supplied by the customer. It is assembled onto the computer through special software and simple proof is prepared before the final printing is done. Plate-making process in flexographic printing is similar to that in other printers. It is just that the relief printer is made out of flexible material so that it can be attached to a cylindrical roller for ink application. Flexographic printing for self-adhesive labels makes more and more use of UV cured inks as they are less toxic and much easier to handle as compared to heat-cured inks. The final stage of flexography is the finishing. Here processes like cutting, folding, coating and binding etc. may be carried out. Flexography is a boon for printing bottle labelsand has found extensive usage in sticker labels meant for food packaging.

JK labels’ infrastructure includes the seven-colour UV flexographic label manufacturing machine- Gallus EM 280, manufactured by world’s best manufacturer of label printing machines, Gallus. Visit www.jklabels.com to know more about the printing service offered by JK Labels.

The Machines That Print the Labels

Product manufacturers rarely know and are hardly interested about how the beautiful and attractive printed labels that they ordered actually become a reality. This is not the ideal situation, as doing so the people who need sticker labels do not appreciate the sophisticated technology and expertise that goes into the making of the labels, and neither realizes how much more the machines and the label manufacturers can do. We shall look into a few of the machines that are currently used by JK Labels and what they are capable of doing:

Gallus EM 280

The Gallus EM 280 is manufactured by Gallus, Switzerland and is the subsidiary of Heidelberg, Germany. The Gallus EM 280 is an excellent machine to produce high quality sticker labels in small and medium sized runs. The Gallus EM 280 comes with an option of printing in seven or eight colours and includes high level of specialisation for applications like tickets, booklet and multi-web labels. The speed at which the labels are produced coupled with the UV technology makes it ideal for most types of labels.

Speedmaster XL 106

The Speedmaster XL 106 is a sheetfed offset printer, as opposed to traditional flexographic ones, and is capable of printing as many as 18000 transparent sheets per hour. The speed and accuracy of the machines is unmatched by any other and is ideal for customers requiring very large volumes of high quality UV printed labels.

Rising Trends in Cosmetic and Healthcare Product labels

Plain and simple labels for the soaps and lotions used two decades back are now well and truly history. Today the labels of FMCG products are perhaps the most advanced in terms of technology and diverse in terms of materials used. It is because printed labels play a very important role in developing an attractive packaging of a product, something that can entice the consumer into trying the product out. Today a large variety of sticker labels, self adhesive labels and transparent labels are being used in the packaging of the FMCG products.

Among the rising trends, transparent labels are perhaps the most widely used today. Most transparent labels are made out of polypropylene, polyethylene and polyester. These transparent labels enable the very innovative form of packaging where the insides of the packaging are visible to the buyer. They are most frequently used together with transparent packaging bottles for products like shower gels, shampoos and other liquid products. Other products like tubes and bottles that are squeezed several times have seen increased use of squeezable self adhesive labels. These labels are usually laminated and moisture resistant so that they withstand the rough handling on the surface. The adhesive of the products also needs to be stronger than the ordinary.

Embossed labels, ‘soft touch’  sticker labels and screen printed labels for added texture are some other new trends in label manufacturing. Embossed labels are used mostly on bottles that are likely to be picked up by the consumer before buying. The embossed logo of the product can give a nice feel to the consumer and persuade him/her to try the product out. The same can be said about ‘soft touch and textured labels. The labels can indeed make the first time buyer to try the product, just because its label feels good in his/her hands.
