The Myth of Legitimacy

In part the rise of LED curing technologies is due to the market’s acceptance of UV-curable inks. Unlike conventional inks, UV inks do not dry through evaporation, but rather must be changed into a solid surface that sits on top of the substrate. A UV light source heats the printed inks which contain photoinitiators and other ingredients. The heat causes photoplymers in the ink to cross link and form a solid layer. The ink sits on the substrate surface rather than being partially absorbed into it, so these inks can have much larger and more intense colour gamuts than conventional offset inks. They are also instantly dry so the prints can move straight into finishing, storage or be readied for shipping. This can hit the bottom line, in that it means faster throughput in the plant and ultimately more jobs on press.

The World Ends, So No More Music

Many designers struggle when it comes to choosing a suitable ICC profile for their artwork, often because they simply don't know what paper or printing process will be used for the final print production. One way around this is of course to use the RGB colour space in the design stage, and only softproof to CMYK when all the print parameters are known. But many designers, and prepress operators and printers as well for that matter, prefer to move to CMYK when the artwork is getting close to the approval stage.
