an innovative printing technology
In the digital era, all images are obtained in the RGB color space and, for printing, it is necessary to transform these colors from RGB to CMYK, so they can be printed. During this transformation, many colors are lost, and therefore details and fidelity to the original, because the RGB color space (light source) is much greater than the CMYK one (color reproduction).
In turn, the human eye can perceive more colors than those which can be printed on a high quality printing in CMYK. That is, with normal methods of printing, we cannot reproduce on a print all colors that our eye catches. This limitation encouraged us to research ways of providing improved color than that obtained on prints.
At Agpograf, we wanted to answer this question, and we set a new challenge: what can we do to move towards a different product?
… Why not print directly on RGB? and, well, why not print without transforming to CMYK, thus transferring all the colors of the original image? This was the beginning of our adventure. Of course, this goal raised many issues that needed to be resolved, starting with the fact that a screen is bright and the paper on which we print is opaque. But even so, we have managed to print most of the RGB color space, and there are even areas where we can offer even more colors than the ones offered by RGB (as shown in the figure).
we have successfully managed to implement the «RGBtoRGB» printing or multichromy, thus obtaining a significant increase of the color
After a year of work, having conducted numerous tests and trials, we have successfully managed to implement the «RGBtoRGB» printing or multichromy, thus obtaining a significant increase of the color spectrum that can be reproduced. Colors that until now seemed impossible to achieve with CMYK printing can now be reproduced without any problems.
We also wanted to add an additional quality plus to «RGBtoRGB» or multichromy printing, so we chose to use the stochastic weft of 20 uM (microns), thus improving the quality of the final printing.
So, today we can say with certainty that we have made a technological breakthrough, allowing to improve the outcome of current printing towards a new concept in the quality of the printed product, better contrast, sharp-ness, brightness, depth and overall fidelity to the original.
