Printer Setup
KODAK PROFESSIONAL ENDURA Metallic Paper is slightly slower than KODAK PROFESSIONAL PORTRA and SUPRA ENDURA Papers. As a starting point, use the same printing times and include a density series to determine your preferred exposure.
Initial conversion to this paper from KODAK PROFESSIONAL Color Metallic Paper involves rebalancing your printers. Since the green speed is about a 1/2 stop faster than Color Metallic Paper, increase your magenta filtration by approximately 15CC.
White-Light Exposure Method
Control color balance with dichroic filters built into the printer or enlarger, or with KODAK Color Printing (CP) Filters (Acetate) placed between the lamp and the negative. You can use any number of filters between the light source and the negative. If you use cyan filtration, use filters with

5.Remove neutral density from your filter pack. For example, if you determine that a filter pack of
40R + 10Y + 10C will give you a pleasing print:
a.Convert any primary filters (R, G, B) to their subtractive equivalents (C, M, Y):
40R = 40M + 40Y.
b.Add filters of the same color: 10Y + 40Y = 50Y.
c.If the new filter pack has all three subtractive colors, cancel the neutral density by subtracting the smallest density value from all three densities:

6.Adjust the exposure for the new filter pack. An exposure time that produced a print of satisfactory density may not produce an acceptable density when you change the filter pack. The following table gives filter factors for calculating exposure adjustments when you use KODAK Color Printing (CP) Filters.

Note: The filter factors listed in the table take into account the effects of filter surfaces.
To use the factors, divide the old exposure time by the factor for any filter you remove. If you add a filter, multiply the time by the factor. If you add or remove two or more filters, multiply the individual factors and use the result as your factor. You may need to modify these factors for your equipment.
