Abstract
We have been making high-performance, highly-reliable imaging charts. It is required to maintain three factors (materials, exposure, and processing) steady at high level. Uniform density cards (Density inconsistency is less than 0.03), Ladder-pattern resolution charts (Maximum resolution is 1,600 DPI), and patch-style density & color charts are produced as ready-made products. Order-made charts are available such as a chart from a digital image file. The chart is produced with digital & analog photographic technology and its quality is excellent though the production line is long and complicated. We are going to develop and produce more variety photographic products.
