Your preference should be based on printing a standard printer test image at the various printing quality dpi settings offered and compare them with your eyes to see which you like best. I went through much of this in my article on this site reviewing the SC-P900.
#RESOLUTION CALCULATOR PRINTING EPSON 7900 DRIVER#
You select in the Print Quality driver settings which of these printing resolutions you prefer. All this contributes very heavily to print quality. These printing resolution numbers don’t begin to tell you much about the complexity of the dithering ink mixing and dot placement that goes on under the hood to produce the photo on paper. There are lower resolutions – down to 1440 large dimension dpi if I remember correctly. If that’s true, should we now upsample to 300 PPIif the native file resolution is less than 300 PPI or upsample to 600 PPI if the native file resolution is between 300 and 600 ppi?įollowing that logic, should one also import files from a card now at 300 PPI as a starting point?Īctually, the maximum printing resolution of an Epson SC-P900/SC-P7570 is 5760 x 1440 dpi. I may be wrong, but the base resolution of the newer Surecolor printers is apparently 300 DPI. The newer Surecolor printers like the P700/900 and the P7570/9570 have a maximum resolution of 1200 x 2400 DPI so they apparently no longer use 360 DPI as the base resolution. This was based upon the fact that Epson printers printed at 360 DPI or 720 DPI. I recall that Jeff Schewe and others had always recommended that the print resolution of a file to be printed with an Epson printer be upsampled in Photoshop or LR to 360 PPI if the native resolution of the file at the desired print size was below 360 PPI or to 720 if the native resolution was between 360 and 720 PPI.
The earlier generations of Epson printers used “printer resolutions” that were 360 DPI or multiples thereof.
