1.2 Goals and Limitations
We feel that a much simpler solution than those proposed by Stone and Schreiber is attractive,even if it eventually falls short of optimum graphic arts quality.We assume that by keeping ‘both the measurement procedure and transformationsoftware as uncomplicated as possible it stands more chance of being broadly accepted by the computer graphics community.The starting assumption is that neither complex technology nor very expensive equipment is needed to get improved results.The additional gain in quality by using more advanced tech- niques may not be worth the investment in time and money,especially if the printer is insensitive to small changes in input data,or is relatively unstable.Images that benefit most from this technique contain continuous gradation,for example,data obtained by sampling photographs or smoothly shaded images obtained from a computer-aided design (CAD) system..
This approach is empirical rather than analytical and provides tools that allow users to adjust the color transformation parameters until a satisfactory appear- ance is obtained.The equipment needed for these tasks is kept to a minimum,assuming that some adjustments can be made by comparing images visually.However,color measurement instruments are needed for calibration of monitors and printers.
This technique is not encapsulated in any known software or hardware product.There is no general solution,only a general method for finding a particular transformation for a specific monitor/printer pair.It is unlikely that the solution developed for one monitor/printer pair will work for another pair.The transfor- mation will work for more than one monitor using the same printer if all monitors are adjusted to produce the same image from a digital file.If necessary,the method can be used to adapt the transformation to optimize a specific image.
