	Plug&Play-CMYK Preview A pioneer development from LaserSoft Imaging enables the scanner preview in SilverFast to correspond 1:1 with the CMYK-preview in Photoshop - that's sensational - making production of perfect color-printing as easy as ever! With this break-through, LaserSoft Imaging enables color reproduction through Plug&Play CMYK for everyone!
	Predictable color with Photoshop SilverFast allows the preview image to match the final image in Photoshop. There is no color drift thanks to the color management system of SilverFast.
