The manufacturers of RA-4 photo paper now offer papers that are optimised for exposure in a digital printer, i.e. through laser or LED. I understand that the digital papers are formulated to give maximum density with a very short exposure. I heard of cases where Dmax of conventional papers could not be reached with the very short exposure times in digital printers, which can be a small fraction of a second at high intensity. I assume that this is due to reciprocity failure. Now I wonder, if one uses these papers that are made for digital, do they have any disadvantages when you expose them conventionally, i.e. at multiple seconds exposure? If the manufacturer improved reciprocity behavior at very short exposure times, does that mean the papers still work well at regular times? Is it simply an improvement of one characteristic while maintaining other qualities of the paper? Characteristic curves are now given for "laser exposure" or ".04 s exposure" in data sheets. But no curve for reciprocity behaviour is given.
