Profile designed for profile for proofer Figure 2 12 Full color chain You only select the emulation profile once in the ColorPro setup but it is used twice The CRDs are used first and then the color space is used to effectively start the second stage of the color chain It could be that the profile that the job was designed for is the same as the device profile that you want to emulate That is the job will ultimately be printed on the press that it was designed for However you may want to proof it on another device first In this case it is reasonable to select the same input profile as the emulation profile for example for the CMYK input This would still give a better route for RGB than just using an RGB input profile and the output profile of the proofer because that does not take any account of the press it is ultimately going to be printed on In the case of the CMYK data this would give a very similar result to just going from the input profile the job was designed for to the proofer profile The point is selecting the same input profile as emulation profile is mainly useful for RGB or mixed RGB CMYK inputs For pure CMYK inputs you may not gain any improvement over using the color chain Input Profile Output that job was gt prone designed for for proofer Figure 2 13 CMYK color chain In a case where the emulation profile is not the same as the profile

INDEX CONTENTS 4 55 gt Appendix F Seeing Color This appendix gives a brief description of the perception and measurement of color It forms an intro duction to understanding the issues in color printing listed in Appendix G Printing Color FI Perception of color The perception of color is both biological and psychological The biological aspect is the eye s detec tion of certain wavelengths of light The psychological aspect is the way the sensation of color is pro cessed by the mind For hundreds of years researchers have tried to express the human perception of color in objective and quantifiable terms But since all people vary in how they process color this has been a formidable task From a purely physical point of view seeing color requires the presence of three elements a light source an object that interacts with the light and a receiver the eye An object has a color because it absorbs some wavelengths and reflects or transmits others For example a tomato appears red because it absorbs green and blue light and reflects red light Light a form of electromagnetic energy can be described as waves The length of a wave is its wave length Wavelengths are measured in nanometers nm that is one millionth of a millimeter Wave lengths between 400 and 700 nm are visible to the human eye Red Green and other colors are names assigned to a certain range of wavelength F2 Additional r

Operator or spot color converted to a gray level and the job requests overprinting This behavior is not defined by the PostScript language and though it is unusual for a job to rely on it sometimes a job assumes this especially when the gray tint arises from a named black spot color which is converted to process For more information see Appendix D Overprinting options Overprint gray images Overprint behavior changed from Harlequin RIP version 4 1 to 5 x and beyond While the old behavior is deemed incorrect there is a desire to selectively use the old behav ior because of the un predictability of some graphic appli cations and to provide for end users the ability to handle legacy work The user parameter is called overprintGrayImages witha default of true which when set overprints gray images If it is set to false gray images will knock out of CMY back grounds Overprint 100 black When this option is selected the RIP overprints 100 black rather then generating knockouts in the other separations The black channel or separation is generated as normal but depending upon the characteristics of the other inks may need to be applied last in the combination process so that it overprints all colors necessary If this option is selected overprinting occurs regardless of whether overprinting is switched on for that graphics object There is no performance penalty incurred by using this fea ture in fact it m
