Color Scanners--The Color of Digital Originals
Is there room for improvement?
Agfa's Chris Parent, product marketing manager, fields this question.
"Truth? It's going to be awfully hard to get any better, more economical and technological scanners, but we could, as an industry, offer improved color fidelity and a greater bit depth."
For a list of scanners, consult Printing Impressions' annual Master Specifier next month.

Will We Need to Change the Way We Scan Color?
Don Rogers, product manager for scanning systems, Heidelberg Prepress
Yes. In fact we are already seeing a move away from traditional CMYK scanning techniques. This is primarily due to both the need for re-purposing of scan data, as well as color management tool improvements.
Although high-end scanning methodologies have been used in CMYK formats to ensure high quality for commercial printing results, there are many factors that, in sum, make these techniques less efficient for today and the future.
When the final goal was to produce film and an analog color proof that represented final press conditions, scanning internally with the "known" conditions that covered paper, ink, dot gain, screen ruling, UCR, GCR, etc. was best accomplished by scanning directly to the CMYK output format.
Today's multimedia output destinations (print, CD, Internet, etc.) require that scan data be processed in a way that will deliver the best results no matter what the final output path or paths may be.
Even when commercial print is the only goal, the number of companies that have multiple presses and even multiple plants make this flexibility necessary because the final location at which the job will print is not always known.
With ever shorter production schedules, the ability to process scans without knowledge of their destination is quickly becoming a requirement.
