Pros of using digital printing over traditional printing methods
The process of printing digital-based images directly onto various media substrates is called as digital printing. Unlike traditional offset printing in digital printing, there is no need for a printing plate. In this type of printing digital files like PDFs or other types of desktop files can be directly sent to the digital printing press. These files then can be then printed on substrates such as paper, photo paper, canvas, fabric, cardstock synthetics, etc.
Digital printing in many ways differs from traditional printing. Offset printing, which is an analog printing method will require printing plates whereas this is absent in digital printing. In offset printing, these print plates are used to transfer an image onto a paper or other substrate. But in digital printing, the image is directly printed on to the media substrate.
As technology is seeing a massive improvement in this present time the digital production print technology is also evolving quickly thereby improving the output quality of digital printing. There are some additional advantages technologically in digital printing such as personalized, variable data printing (VDP), cost-effective short runs, fast turnarounds and print-on-demand.
Currently, there are various types of digital printing machines such as sheet-fed production printers, production inkjet printers, continuous feed printers and cut-sheet digital presses. In order to get vibrant prints inks used in digital printing are of high-quality. The commonly used inks are cyan, magenta, yellow and black (CMYK) toner and ink. Also, specialty dry inks are used for metallic, white or clear effects.
A few of the advantages of using digital printing are that they are cost-effective, on-demand production and running short print quicker. Personalization is made easy in digital printing where you can modify images easily through VDP. As advancements are rapidly increasing digital printing machines are closing the gap on offset output.
UV Printing in this Modern World
Introduction to UV printing:
UV printing is a unique method of digital printing utilizing ultraviolet (UV) light to dry or cure ink, adhesives or coatings almost as soon as it hits the paper or aluminum, foam board or acrylic. The technique can be used to print on almost anything. High5 Prints uses this technique more accurately to give you prints of the best qualities. This work principle makes High5 Prints the best UV printing service in Coimbatore. Asides from printing banners when you search for the best flex printing service in Coimbatore it will be High5 Prints that would be resounded.
Development of UV from its initial years:
The technique of UV curing – the photochemical process of drying - was originally introduced as a means of quickly drying gel nail polishes used in manicures, but it has recently been adopted by the printing industry where it is used to print on anything from signage and brochures to bottles. Due its high quality in printing it is widely used for brochure printing, visiting card printing in Coimbatore in the recent times.
Traditional Printing and its Cons:
The process is the same as traditional printing, the only difference is the inks used and the drying process – and the superior products produced. In traditional printing, solvent inks are used because these can evaporate and release volatile organic compounds (VOCs) which are harmful to the environment. The method also produces and uses heat and an accompanying odor. Furthermore, it requires additional spray powders to help with the ink offsetting process and drying, which can take several days. The inks are absorbed into the printing medium, so colours can seem washed out and faded. The printing process is limited mostly to paper and card mediums, so it can’t be used on materials such as plastic, glass, metal, foil or acrylic like UV printing. These drawbacks have urged High5 Prints to implement UV printing which we use it commonly for online printing, flyer printing and thus making us the best digital printing service in Coimbatore.
How it Works:
In UV printing, mercury/quartz or LED lights are used for curing instead of heat; the specially designed high-intensity UV light closely follows as the special ink is distributed on the printing medium, drying it as soon as it is applied. Because the ink transforms from a solid or paste to a liquid almost immediately, there is no chance for it to evaporate and so no VOCs, toxic fumes or ozone are released, making the technology environmentally friendly with almost a zero-carbon footprint. This modern technology can be seen in use and this aspect make us the most successful printing press in Coimbatore.
The ink, adhesive or coating contains a mixture of liquid monomers, oligomers – polymers consisting of few repeating units - and photo initiators. During the curing process, high-intensity light in the ultraviolet part of the spectrum, with a wavelength between 200 and 400 nm, is absorbed by the photo initiator which undergoes a chemical reaction – chemical cross linking - and causes the ink, coating or adhesive to harden instantly. Business card printing in Coimbatore is growing in demand gradually and to meet the satisfaction of the clients High5 Prints use UV printing method for accuracy and quality.
