I don't know so much about photographic printing, but I think that the amount of ink used in smaller or higher resolutions can be de same, or almost exactly de same, cause the only different thing on printing at higher resolutions is that the "ink dot" is smaller, but there are a lot of "dots" more ... ¿isn't it? At the end ... the amount of paper to be "painted" in low resolution is the same as in high resolution. Don't sure about this ... but maybe ... just guessing __________________ Llorenç Herrera Aznar http://www.lorenzoherrera.com http://www.fotopunto.com -----Mensaje original----- De: owner-photoforum@xxxxxxxxxxxxxxxxxxxxxx [mailto:owner-photoforum@xxxxxxxxxxxxxxxxxxxxxx] En nombre de howard Enviado el: lunes, 02 de mayo de 2005 13:30 Para: List for Photo/Imaging Educators - Professionals - Students Asunto: Half Res Half Ink? Dear Alberto, I have no real idea except that I'd expect the principle of mathematical scaling to work... Thus 720dpi = 1/2 1440 dpi along the horizontal axis AND along the vertical axis. (?) If my assumption is correct then the scale factor will be 1/2 * 1/2 = 1/4 Thus the ink usage will be 1/4 of 1440 dpi. I have an Epson R300. I always print at 720 dpi. The rare times I tried to compare to the printer's higher resolution I couldn't see any difference with the naked eye... But it certainly took much longer! No doubt forum members will disagree!
