4. SPLITGRADE is an electronic instrument intended to control the contrast range of variable contrast papers VC during the enlarger process By printing the picture in two steps first through the Yellow filter and then through the Magenta filter or first through Magenta and then through Yellow the reproduction of the different tonal values is greatly improved by usage of the SPLITGRADE The contrast range of variable contrast papers will be perfectly matched to the given contrast range of the negative The characteristics of various variable contrast papers from AGFA AMALOCO FORTE ILFORD KENTMERE KODAK TETENAL and ORIENTAL are stored in the SPLITGRADE controller unit These values can be easily updated by floppy disk or download from Internet via PC if the manufacturer s paper characteristics should change The exposure time is automatically calculated for each gradation of the programmed and selected paper The exposure time and the gradation are calculated after scanning the projected picture using the probe until the darkest and the brightest areas were detected An acoustic and optical signal supports finding a quick result The evaluation and the composition of the picture takes place under white light When the filter module is disconnected the SPLITGRADE controller can be used as a high quality B amp W analyser and exposure meter The focus light will be automatically switched OFF after 5 minutes The use of the SPLITGRADE
