Paper Abstract

For the sake of clarity, two fundamental questions should first be addressed: "WHAT IS SOFTPROOFING AND WHY WOULD ONE WANT TO SOFTPROOF?" Softproofing is just another off-press proof for verification and approval of color and its corrections. Proofing is done on an image presented on an imaging display and is called a "soft" image because it disappears when turning off the display. The major purpose of soft proofing is to significantly decrease turnaround time in the color approval process. Although soft proofing ,in all likelihood, will not replace other color proofs completely, it offers an important contribution to to increased productivity in the Graphic Arts Industry. It should be obvious to all off us that this technology will only prove useful if the soft image is a true representation of the final proof on which the customer will sign off to provide the binding contract between the customer and color separator. Essential factors for a match between the soft image and a hard copy proof--whether it be photomechanical proofs, such as transparencies, digital proofs or press proofs--are numerous and complex. Probably the most important requisite for any proofing system is CONSISTENCY. Color consistency in the display over time (from day to day), over space (from shop to shop, machine to machine), and over image content. Undoubtedly this is what kept a lot of you from using softproof techniques heretofore. Before describing what problems in traditional displays keep you from achieving consistency and thus use soft proof techniques, it may be worth pausing here to examine and get a better understanding of the transfer curve of a display. (see fig 1) The graph represents the light output for the three colors and the
