Digital printing has evolved over the past few decades and is one of the most preferred processes for good quality photo printing. However, good quality is of no use unless there is something inherent in the print which protects it from exposure, be it natural factors or artificial ones. An image which is to be used in a covered area is not subjected to as much exposure, however an image which is to be displayed somewhere in the open, requires a protective layer. It is not always possible to cover an image which is on display for either advertising or showing a new concept of a business.
Newer technologies have been incorporated in the latest digital printers. This has made the printing process efficient and easier to carry out. An innovative technique is now being used to make the images printed using a digital printer more durable in terms of quality. Keeping the concern about fading off of printed images due to water, dust, sunrays and other external influences, solvent based printing is being done rather than water based printing. Solvent based inks are used to print large images on PVC or other media. Since banners and other displays on walls, vehicles and many such backgrounds are constantly exposed to dust and pollution, the images are protected through solvent based printing cetak kartu nama murah. As a result, these images retain their quality for as long as 3-4 years. Such images made on solvent based inks do not require lamination and need not be protected in any other manner. This is because they inherently possess a protective layer.
A type of printing which uses water based ink is termed as aqueous printing. Compared to solvent based printing, water based images are unprotected and are suitable for display only inside a covered area. However, printing some fine images using aqueous inks lasts for more than several hundred years. Although these images are kept inside a room, the moisture may creep in very easily over the images. The printed images when kept under slightly protected conditions can retain their original quality and texture. Prints made from aqueous ink are preferred by artists and professional photographers.
Even though the inks using solvents make printing better and durable, a much safer option is to use Latex inks as they are eco-friendly. Use of PVC sheets is also dangerous as they are not easily disposed off in a manner that does not harm the environment. Both water and solvent based printing produce good quality images, where the choice completely depends on requirements.
