RE: filmscanners: Why not sRGB ?

["LAURIE SOLOMON" <LAURIE@advancenet.net>]

No, I am not certain about it; but it seems entirely logical to me that a
six color printer will have  or be able to effectively use a different gamut
than a four color printer and that the general/business inkjet printers
which are more focused on presenting color presentational graphics and
illustration rather than color photography would use a gamut closer to the
sRBG than would be the case with printers dedicated to printing photographs.

This in no way questions what you have said below; it just suggested that
the gamut used by some inkjet printers may be closer to sRBG than others
although not necessarily identical to sRBG; and thus, we should be careful
not to lump all inkjets into the same category when talking about color
spaces.

Laurie,

Are you sure about that?

I don't know, but I suspect that the 4-color general/business application
inkjets also print colors outside of the sRGB color space, primarily
because, in general, some ink colors are outside of the colors visible on
the monitor just as some colors visible on the monitor are not printable
using normal printing processes, i.e. inkjets.

| shAf,
| What the original poster fails to take into account and you failed to
point

| inkjets are the same.  Some are 4 color general/business application
| printers while others are photo application printers (4 or 6 color).  They
| do not all have the same color gamut.  The lower end general /business
color
| printers probably do not need a larger gamut than sRBG; whereas the higher
| end photo printers may produce much higher quality outputs with the larger
| color gamut.  Obviously one can print on any color inkjet with the
narrower
| sRBG gamut; and in that sense it is suitable for all inkjets; however that
| does not make it optimum for all inkjets. :-)
