When i have to convert an RVB pic to a CMYK, photoshop allow me to look at the CMYK layers. So, i can easely transform my layers to have a better convertion.
But, when i have to print, using an Epson or other, i cant have the layer simulation of my printing. So i have to use cmd+Y (using the icc of my print and paper) to preview and look at the composite.... I really prefer to have the possibility to work on layer... Is there a way to simulate the layer of a personal printer, so i will be able to work on them like i do with CMYK ?
